Definitions
- This invention relates to food products, including vegetable protein products, baked products, and animal protein-containing food products and preparations, more specifically to food products having improved moisture retention and shelf-life.
- U.S. Patent No. 5,964,983 uses alkaline and/or acid conditions to make their microfibrillated cellulose. Dinand discloses the use of alkaline and/or acid conditions to make microf ⁇ brillated cellulose, and also does not disclose the combination of water, fiber and shortening directly together to make a reduced fat shortening, oil, margarine, or butter.
- U.S. Patent No. 5,766,662 (Inglett) describes replacing fat, but specifically states that the fat replacement product is the product made according to his invention is a product made through the combination of mechanical and chemical processes. Additionally, the dry product he makes needs to be sheared in a shearing device, i.e., a high speed blender, before the product can be used for fat replacement. This work does not disclose the direct combination of water, fiber, and shortening together to make a reduced fat shortening, oil, margarine, or butter.
- Animal protein-containing food products including whole meat, ground or chopped meat, pureed meat and deboned whole meat products, such as poultry, ham, roast beef, frozen fish filets, shrimp, scallops and fine paste sausages, contain moisture in the form of natural water content and, in some cases, water that is added during processing.
- the water content of such products has a pronounced effect on both product weight and product sensory qualities.
- Various additives such as, for example, polyphosphates, starches, gums, and carrageenans are used as to enhance the moisture retention of such food products.
- Polyphosphates are the most commonly used moisture retention additive, but may undesirably increase the phosphorus content of food processing effluents.
- U.S. Patent No. 7,001,630 (Bender) describes a method for treating meats to retain moisture by injecting or otherwise adding alkali metal silicates into the meat. Injection of marinades into meats is well known (as described in US Patent No. 5,431,937), but the moisture content is not retained in the product by effective means.
- U.S. Patent No. 4,031,267 (Berry et al.) describes an expanded protein product containing up to about 35% by dry weight of a fat or oil that can be prepared by forming a mixture comprising a proteinaceous material, fat or oil, and minor amounts of a finely divided non-proteinaceous and non-farinaceous filler material, hereinafter referred to simply as filler material.
- the expanded product having a meat-like texture is prepared by subjecting the mix to heat and mechanical working such as in a cooker- extruder, and extruding the composition from a zone of higher pressure into a zone of lower pressure.
- U.S. Patent Nos. 6,582,964 and 6,423,364 (Altemueller) describes meat product containing a blend of at least one meat and an unrefined plant protein material.
- the unrefined plant protein material of the meat product has a nitrogen solubility index of from about 30% to about 80% and at least one of the following properties: a salt tolerance index of from about 30% to about 80%; a water hydration capacity of at least 3.75 times the weight of the unrefined plant protein material; or a viscosity of at least 500 centipoise at a temperature of 15C to 25C.
- the unrefined plant protein material of the meat product has at least one of the following properties: a gel weight of at least 30 grams at a temperature of from about 15C to about 25C in a 5 fluid ounce mixture containing 5 parts water per 1 part of unrefined plant protein material, by weight; or a refrigerated gel strength of at least 50 grams when combined with 5 parts of water per part of soy material, by weight.
- the unrefined plant protein material is an unrefined soy protein material, most preferably soy flour, soy grits, soy meal, or soy flakes. Alternative methods of maintaining moisture in meats is desirable. All references cited in this document are incorporated in their entirety by reference.
- the present invention is directed to an animal protein- containing food product, comprising animal protein, water and an amount of alkali silicate effective to enhance the moisture retention of the food product and as a replacement for butter, margarine, shortening, oil and other additives.

All types may be broken down further with leavened and unleavened products, although with one of the products, the chip, leavening is seldom used.
- Each of these cracker products has a crust component in which the outermost surface (at least initially after cooking) tends to be more oxidized or more stressed (e.g., browned, crisper, bubbled into a thinner exterior than the overall thickness of the cracker product, more brittle exterior layer component) than the interior of the cracker product.

- HRC highly refined cellulose
- the HRC may have an average pore diameter of at least about 5 angstroms and may have a Langmuir surface area of at least about 7 m 2 /g. That reference is incorporated herein in its entirety. Published U.S. Patent Applications Nos. 20050274469; 20050271790; 20050074542; 20040086626; and 20030116289 disclose highly refined cellulose materials.
- HRC material may alternatively be described as a fiber material that has a total dietary fiber (TDF) content greater than 30% as measured by AOAC 991.43 and a water holding capacity greater than five parts water per part fiber as measured by AACC 56-30 followed literally or with modifications as listed in the specifications and is less than 90% soluble fiber.
- TDF total dietary fiber

- the combination of the fiber and gum is preferably made in advance of the mixture of the fiber/gum composition to the food product, which in part explains the relatively wide range of weight additions of these materials that is possible.
- the fiber ad gum materials are precombined, in the 5-50% range described above, preferably in a
- Highly refined cellulose fibers may be produced with a wide range of properties and by various distinct processes.
- TDF total dietary fiber
- WHC water holding capacity
- AACC 56-30 we are defining highly refined cellulose fibers as those with a total dietary fiber (TDF) content greater than 30% as measured by AOAC 991.43 and a water holding capacity (WHC) greater than five parts water per part fiber as measured by AACC 56-30 followed literally or with the following modifications; namely, 1) using shearing to hydrate the fiber mass, and/or 2) only using the first stage steps (1-4) of AACC 56-30 to find the approximate WHC and using this as the final WHC value, and/or 3) determining the final or approximate WHC value at 2-10% solids instead of 10% or using 2.5 g of fiber mass for the sample size instead of 5 g as the procedure calls for.
- TDF total dietary fiber
- WHC water holding capacity
- the varying products can produce highly refined cellulose products with a wide range of properties that are based in part upon both on the starting organic mass containing fibers and the process steps, parameters and reagents.
- the underlying objective of the various processes is to take fibrous and or cellular mass (usually from agricultural products, especially flora (plants), and to reduce the structure in maximum ways. For example, as the original mass is sheared, shredded, exploded, disrupted or otherwise reduced from a complete cellular structure to fibrils, fibers, particles and other structures that form parts of the original organic mass.
- Various references that teach such processes and resulting expanded, highly refined cellulose materials include but are not limited to U.S. Patent Nos.
- dietary fiber generally refers to the use of bulk fiber material, usually in its less processed state (e.g., dried but not highly sheared) so that the fiber remains substantially intact and even cell wall structure and cell morphology can be readily seen under microscopic examination (e.g., 4OX to 500X examination).
- WRC Water-Retention Capacity
- ORC Oil-Retention Capacity
- the Langmuir surface area values were obtained by relating the surface area to the volume of gas adsorbed as a monolayer.
- Results and Discussion - Pore Size and Surface Area Average pore size is a measure of openness of the HRC structure. The average pore size increased rapidly as NaOH concentration was increased to 0.007%, then slowly with further increase in NaOH concentration. The surface area reached a maximum value at 0.007% NaOH, which also coincides with the maximum WRC discussed above. The decrease in surface area after the maximum value seems to suggest an increase in the ratio of large pores to small pores, which may contribute to the decrease in total surface area.
- the processes of the Lundberg Application removes lignin to a sufficient degree or substantially inactivates it such that undesirable fiber clumping does not occur
- WHC/viscosity between the two products (the Chen product and the product of the Lundberg Application) in a wet form, but there is a significant and commercially and technically important difference between the products/processes is that 1) Chen never provided a method for drying the gel product or 2) rehydrating the dry product.
- the present process for citrus has no required chemical treatment and does not need any mechanical treatments to produce a dry product that rehydrates to a high WHC/viscosity gel. Additionally, there is less concern about all the surface area, and pore size measurements.
- the HRC materials should provide a viscosity of at least 200 cps (preferably at least 300 cps) at 2OC in a concentration of 3% in deionized water after mild stirring for 4 hours, a water retention capacity of at least 8X the dry weight of fiber (preferably at least 10X, at least 15X and at least 20X), which may also be determined by filtering saturated fiber mass, draining excess water (e.g., under mild pressure of 50g/10cm for three minutes), weighing the drained wet fiber mass, then dehydrating the drained mass (to less than 5% water retention/weight of the fiber) and weighing the dried product to determine the amount of absorbed water removed.
- This latter method is less preferred, but can address the issue that drying of fibers often changes their physical properties, and particularly dried fibers (unless additionally sheared) often lose WRC after drying.
- a highly refined cellulosic material e.g., cellulose, modified celluloses, derivatized celluloses, hemicellulose, lignin, etc.
- a highly refined cellulosic material e.g., cellulose, modified celluloses, derivatized celluloses, hemicellulose, lignin, etc.
- product can be prepared by generally moderate treatment and still provide properties that are equivalent to or improved upon the properties of the best highly refined cellulose products produced from more intense and environmentally unfriendly processes.
- Fruit or vegetable cells with an exclusively parenchymal cell wall structure can be treated with a generally mild process to form highly absorbent microfibers. Cells from citrus fruit and sugar beets are particularly available in large volumes to allow volume processing to generate highly refined cellulose fibers with both unique and improved properties.
- EPM's parenchymal microfibers
- EPM's have improved moisture retention and thickening properties that enable the fibers to provide unique benefits when combined into edible products (e.g., baked goods, liquefied foods, whipped foods, meats, meat fillers, dairy products, yogurt, frozen food entrees, ice cream, etc.) and in mixtures that can be used to generate edible food products (e.g., baking ingredients, dehydrated or low hydration products).
- a new process for making HRC cellulose from parenchyma cell wall products is performed in the absence of a hydroxide soaking step.
- This is a significant advance over the prior art as described by the Chen and Lundberg patents.
- Dinand, et al. (U.S. Patent No. 5,964,983) also recommends the use of a chemical treatment step in addition to bleaching.
- we are able to attain higher functionality (measured as viscosity) compared to Dinand et al. even though we use less chemical treatment, which is likely due to the higher amount of shear and chemical energy we put into the materials.
- the product is able to display the same or improved water retention properties and physical properties of the more strenuously refined agricultural products of the prior art, and in some cases can provide even higher water retention values, thickening and other properties that can produce unique benefits in particular fields of use.
- General descriptions of the invention include a highly refined cellulose product comprising microfibers derived from organic fiber plant mass comprising at least 50% by weight of all fiber mass as parenchymal fiber mass, the highly refined cellulose product having an alkaline water retention capacity of at least about 25g HbO/g dry highly refined cellulose product and methods for providing and using these products.
- the highly refined cellulose product may have a water retention capacity of at least 50g HbO/g dry highly refined cellulose product.
- Parenchymal cell walls refer to the soft or succulent tissue, which is the most abundant cell wall type in edible plants. For instance, in sugar beets, the parenchyma cells are the most abundant tissue the surrounds the secondary vascular tissues (xylem and phloem). Parenchymal cell walls contain relatively thin cell walls compared to secondary cell walls are tied together by pectin (Haard and Chism, 1996, Food Chemistry. Ed. By Fennema. Marcel Dekker NY ,NY) In secondary cell walls (xylem and phloem tissues), the cell walls are much thicker than parenchymal cells and are linked together with Iignin (Smook). This terminology is well understood in the art.
- dry or “dry product” refers to a mass that contains less than 15% by weight of fibers as water.
- the organic fiber mass comprises at least 50% by weight of fiber mass from organic products selected from the group consisting of sugar beets, citrus fruit, grapes, tomatoes, chicory, potatoes, pineapple, apple, carrots and cranberries.
- a food product or food additive may have at least 0.05 percent by weight solids in the food product or food additive of the above described highly refined cellulose product.
- the food product may also have at least about one percent or at least about two percent by weight of the highly refined cellulosic fiber of the invention.
- a method for refining cellulosic material may comprise: soaking raw material from organic fiber plant mass comprising at least 50% by weight of all fiber mass as parenchymal fiber mass in an aqueous solution with less than 1% NaOH; draining the raw material and allowing the raw material to sit for a sufficient period under conditions (including ambient conditions of room temperature and pressure as well as accelerated conditions) so that the fibers and cells are softened so that shearing can open up the fibers to at least 40%, at least 50%, at least 60%, or at least 70, 80, 90 or 95% of their theoretic potential. This will usually require more that 4 hours soaking to attain this range of their theoretic potential. It is preferred that this soaking is for more than 5 hours, and preferably for at least about 6 hours.
- This soaking time is critical to get the materials to fully soften.
- a low alkaline concentration is used in the soaking, without the set time, the materials do not completely soften and can not be sheared/opened up to their full potential.
- This process produces soaked raw materials; and the process continues with refining the soaked raw material to produce refined material; and drying the soaked raw material.
- the process may perform drying by many different commercial methods, although some display improved performance in the practice of the present invention. It is preferred that drying is performed, at least in part, by fluid bed drying or flash drying or a combination of the two. An alternative drying process or another associated drying step is performed at least in part by tray drying.
- fluid bed drying may be performed by adding a first stream of organic fiber plant mass and a second stream of organic fiber plant mass into the drier, the first stream having a moisture content that is at least 10% less than the moisture content of the second stream or organic fiber plant mass.
- the use of greater differences in moisture content is also within the scope of practice of the invention.
- the water may be extracted with an organic solvent prior to drying.
- the second stream of organic fiber plant mass may have at least 25% water to solids content and the first stream may have less than 15% water to solids content.
- These processes may be practiced as batch or continuous processes.
- the method may use chopping and washing of the cellulose mass prior to soaking.
- Another description of a useful process according to the invention may include draining and washing the soaked raw material in wash water to produce washed material; bleaching the washed material in hydrogen peroxide to produce a bleached material; and washing and filtering the bleached material to produce a filtered material.
- the drying of an expanded fiber material according to the invention may use room temperature or higher air temperatures that dry the expanded fiber product and maintain the fiber material's functionalities of at least two characteristics of surface area, hydrogen bonding, water holding capacity and viscosity. It is also useful to use backmixing or evaporating to bring the organic fiber plant mass to a solids/water ratio that will fluidize in air in a fluid bed air dryer. This can be particularly performed with a method that uses a fluid bed dryer or flash dryer to dry the expanded or highly refined cellulosic fiber product.
- any surface area expanded cellulosic product can be dried and a functional product obtained and is not limited to parenchyma cell wall materials.
- the fiber products of the invention may be rehydrated or partially rehydrated so that the highly refined cellulose product is rehydrated to a level of less than 9Og H 2 OZg fiber mass, 7Og H 2 OZg fiber mass, 5Og H 2 0/g fiber mass or rehydrated to a level of less than 30g H 2 OZg fiber mass or less than 2Og H 2 OZg fiber mass.
- This rehydration process adjusts the functionalities of the product within a target range of at least one property selected from the group consisting of water holding capacity, oil holding capacity, and viscosity and may include the use of a high shear mixer to rapidly disperse organic fiber plant mass materials in a solution.
- the method may include rehydration with soaking of the dry materials in a solution with or without gentle agitation.
- the HRC dispersion of the present invention is a highly viscous, semi- translucent gel.
- HRC embodiments comprise dried powders that are redispersable in water to form gel-like solutions.
- the functional characteristics of HRC are related to various properties, including water- and oil-retention capacity, average pore size, and surface area. These properties inherently relate to absorption characteristics, but the properties and benefits provided by the processes and products of the invention seem to relate to additional properties created in the practice of the invention.
- the present invention also includes an aqueous HRC gel having a lignin concentration of about one to twenty percent (1 to 20%).
- the HRC products of the present invention exhibit a surprisingly high WRC in the range of about 20 to at least about 56 g H ⁇ O/g dry HRC. This high WRC is at least as good as, and in some cases, better than the WRC of prior art products having lower or the same Hgnin concentrations.
- the HRC products exhibit some good properties for ORC (oil retention capacity).
- a general starting point for a process according to the invention is to start with raw material of sufficiently small size to be processed in the initial apparatus (e.g., where soaking or washing is effected), such as a soaker or vat.
- the by-product may be provided directly as a result of prior processing (e.g., juice removal, sugar removal, betaine removal, or other processing that results in the fiber by-product.
- the process of the present invention may also begin when raw material is reduced in size (e.g., chopped, shredded, pulverized) into pieces less than or equal to about 10 x 5 cm or 5 cm x 2 cm.
- Any conventional type of manual or automated size reduction apparatus can be used, such as a knife or a larger commercially-sized chopper.
- the resulting sized raw material is then washed and drained, thus removing dirt and unwanted foreign materials.
- the washed and chopped raw material is then soaked.
- the bath is kept at a temperature of about 20 to 100 0 C. The temperature is maintained within this range in order to soften the material.
- about 100 g of chopped raw material is soaked in a 2.5 liter bath within a temperature range of about 20 to 80 degrees Centigrade for 10 to 90 minutes.
- the resulting soaked raw material is subjected to another washing and draining.
- This washing and additional washing and draining tend to be more meaningful for sugar beets, potatoes, carrots (and to some degree also tomatoes, chicory, apple, pineapple, cranberries, grapes, and the like) than for citrus material.
- sugar beets, potatoes, carrots growing on the ground rather than being supported in bushes and trees as are citrus products, tend to pick up more materials from the soil in which they grow.
- Sugar beets and carrots tend to have more persistent coloring materials (dyes, pigments, minerals, oxalates, etc.) and retained flavor that also are often desired to be removed depending upon their ultimate use.
- the soaked raw material is washed with tap water.
- the material is drained. This is optionally followed by bleaching the material with hydrogen peroxide at concentrations of about one (1) to 20% (dry basis) peroxide.
- the bleaching step is not functionally necessary to effect the citrus and grape fiber conversion to highly refined cellulose.
- some chemical processing may be desirable, although this processing may be significantly less stressful on the fiber than the bleaching used on corn-based HRC products. From our experience, some chemical step is required for sugar beets, and bleaching is one option. Using alkaline pretreatment baths is another option. Acid treatment or another bleaching agent are other options.
- the material is optionally bleached at about 20 to 100 0 C for about five (5) to 200 min.
- the bleached material is then subjected to washing with water, followed by filtering with a screen.
- the screen can be any suitable size. In one embodiment, the screen has a mesh size of about 30 to 200 microns.
- the filtered material containing solids can then be refined (e.g., in a plate refiner, stone mill, hammer mill, ball mill, or extruder.).
- the filtered material entering the refiner e.g., a plate refiner
- the refining can take place in the absence of water being added.
- the plate refiner effectively shreds the particles to create microfibers.
- the plate refiner which is also called a disk mill, comprises a main body with two ridged steel plates for grinding materials. One plate, a refining plate, is rotated while a second plate remains stationary. The plates define grooves that aid in grinding.
- One plate refiner is manufactured by Sprout Waldron of Muncy, PA and is Model 12-ICP. This plate refiner has a 60 horsepower motor that operates at 1775 rpm. Water may be fed into the refiner to assist in keeping the solids flowing without plugging. Water assists in preventing the refiner's plates from overheating, which causes materials in the refiner to burn. (This is a concern regardless of the type of grinding or shearing device used.).
- the distance between the plates is adjustable on the refiner. To set refining plate distances, a numbered dial was affixed to the refining plate adjustment handle. The distance between the plates was measured with a micrometer, and the corresponding number on the dial was recorded. Several plate distances were evaluated and the setting number was recorded.
- the microf ⁇ bers may then be separated with a centrifuge to produce refined materials.
- the refined materials are then diluted in water until the solids content is about 0.5 to 37%.
- This material is then dispersed. In one embodiment, dispersing continues until a substantially uniform suspension is obtained, about 2 to 10 minutes. The uniform suspension reduces the likelihood of plugging.
- the resulting dispersed refined materials may then be homogenized in any known high pressure homogenizer operating at a suitable pressure. In one embodiment, pressures greater than about 5,000 psi are used.
- the resulting highly refined cellulose (HRC) gel may display a lignin content of about 1 to 20% by weight, depending in part upon its original content.
- All of the mechanical operations, refining, centrifuging, dispersing, and homogenizing could be viewed as optional, especially in the case of citrus pulp or other tree bearing fruit pulps. Additionally, other shearing operations can be used, such as an extruder, stone mill, ball mill, hammer mill, etc.
- citrus pulp the only processes that are needed to produce the expanded cell structure are to dry (using the novel drying process) and then properly hydrate the raw material prior to the expanding and shearing step of the process of the invention. This simple process could also be used in other raw material sources.
- Hydration is a term that means reconstituting the dried fiber back to a hydrated state so that it has functionality similar to the pre-dried material. Hydration can be obtained using various means. For instance, hydration can occur instantly by placing the dry products in a solution followed by shearing the mixture. Examples of shearing devices are a high shear disperser, homogenizer, blender, ball mill, extruder, or stone mill. Another means to hydrate the dry materials is to put the dry product in a solution and mix the materials for a period of time using gentle or minimal agitation. Hydrating dry materials prior to use in a recipe can also be conducted on other insoluble fibrous materials to enhance their functionality.
- any type of convective drying method can be used, including a flash dryer, fluid bed dryer, spray dryer, etc.
- a dryer that can be used is a fluid bed dryer, with dry material being added to the slurry to equilibrate the moisture content in the materials. It has been found that by adding 5:1 to 1:1 dry to wet materials within the fluid bed drier improves the air flow within the drier and the material may be effectively dried. In the absence of the combination of "dry” and “wet” materials, the slurry will tend to merely allow air to bubble through the mass, without effective drying and without a true fluid bed flow in the drier.
- wet and dry are, of course, somewhat relative, but can be generally regarded as wet having at least (>40% water/ ⁇ 60%solid content] and dry material having less than 20% water/80% solid content).
- the amounts are not as critical as the impact that the proportional amounts of materials and their respective water contents have in enabling fluid flow within the fluid bed drier. These ranges are estimates. It is always possible to use "wet" material with lower moisture content, but that would have to have been obtained by an earlier drying or other water removal process. For purpose of economy, and not for enabling manufacture of HRC microfibers according to the present invention from citrus or beet by-product, it is more economical to use higher moisture content fiber mass as the wet material.
- a flash drier may also be used alternatively or in combination with a fluid bed drier to effect moisture reduction from the citrus or beet by-product prior to produce a functional dry product. It would be necessary, of course, to control the dwell time in the flash drier to effect the appropriate amount of moisture reduction and prevent burning.
- One aspect of the drying process is useful for the drying of any expanded cellulose products, especially for the drying of highly refined cellulose fibers and particles that have been extremely difficult or expensive to dry. Those products have been successfully dried primarily only with freeze drying as a commercially viable process. That process is expensive and energy intense.
- a method for the drying of any expanded cellulose fiber or particle product comprises drying an expanded cellulose product by providing a first mass of expanded cellulose fiber product having a first moisture content as a weight of water per weight of fiber solids; providing a second mass of expanded cellulose fiber product having a second moisture content as a weight of water per weight of fiber solids, the second moisture content being at least 20% less than said first moisture content; combining said first mass of expanded cellulose fiber product and said second mass of expanded cellulose product to form a combined mass; drying said combined mass in a drying environment to form a dried combined mass.
- the method may have the dried combined mass dried to a moisture content of less than 20, less than 10, less than 8, less than 5 or less than 3 H 2 0/g fiber mass.
- the method by way of non-limiting examples, may use drying environments selected from the group consisting of, flash driers, fluid bed driers and combinations thereof.
- the rehydration and shearing (particularly high shearing at levels of at least 10,000 sec "1 , preferably at least 15,000 sec "1 , more often, greater than 20,000, greater than 30,000, greater than 40,000, and conveniently more than 50,000 sec '1 (which is the actual shearing rate used in some of the examples) of the dry fiber product enables the resultant sheared fiber to retain more moisture and to retain moisture more strongly. It has been noted in the use of materials according to the practice of the invention that when the fiber products of the invention are rehydrated, the water activity level of rehydrated fiber is reduced in the fiber (and the fiber present in a further composition) as compared to free water that would be added to the further composition, such as a food product.

Unless otherwise specified, the concentrations of highly refined cellulose given herein are based on the weight of non-hydrated highly refined cellulose.
- an amount of highly refined cellulose effective to provide an animal protein-containing food product having (based on about 100% w/w of the food product) from about 1% w/w to about 30% w/w muscle protein, from about 30% w/w to about 80% w/w water, up to about 50% w/w fat, and from about 0.005% w/w to about 3.0% w/w highly refined cellulose, should be used.
- the animal protein-containing food product may optionally, contain other ingredients, such as for example, cereal products, milk proteins, sweeteners, soy proteins, vegetable proteins, and salts.
- moisture retention additives such as for example, polyphosphates, starches, gums, silicates, emulsifiers, or hydrocolloids such as carrageenans may be used in addition to the highly refined cellulose.
- one or more ingredients comprising, for example, ground meat, of the animal protein-containing food product are contacted, associated with, imbibed with, injected with or otherwise combined with the highly refined cellulose, in its dry or hydrated (rehydrated) form.
- the food product ingredient may be treated by mixing the ingredient with highly refined cellulose in solid particulate form. The highly refined cellulose treated ingredient may then be incorporated into the food product.
- Preferred amounts of highly refined cellulose by weight of solid are greater than about 0.05% w/w, more preferably about greater than about 0.1% w/w, and most preferably from about 0.2% w/w to about 1% w/w highly refined cellulose concentration in the animal protein-containing food product.
- the animal protein-containing food product is contacted with the alkali silicate by contacting highly refined cellulose, in the form an aqueous highly refined cellulose solution, suspension or dispersion, with the food product.
- the food product may be contacted with an aqueous composition of the highly refined cellulose by tumbling, dipping, immersion, injection, massage marinating, or by any other suitable means.
- the rehydration and shearing of the dry fiber product enables the resultant sheared fiber to retain more moisture and to retain moisture more strongly. It has been noted in the use of materials according to the practice of the invention that when the fiber products of the invention are rehydrated, the water activity level of rehydrated fiber is reduced in the fiber (and the fiber present in a further composition) as compared to free water that would be added to the further composition, such as a food product.
- the food products that result from cooking with 0.1 to 50% by weight of the HRC fiber product of the invention present has been found to be highly acceptable to sensory (crust character, flavor/aroma, grain/texture, taste, odor, and freshness, especially for mixes, frozen foods, baked products, meat products and most particularly for bakery goods, bakery products, and meat products) tests on the products.
- the products maintain their taste and mouth feel qualities longer because of the higher moisture retention.
- the high water absorbency and well dispersed nature of the product also lends itself to be an efficient thickening agent/suspending agent in paints, salad dressings, processed cheeses, sauces, dairy products, meat products, and other food products.
- the HRC products of the present invention possess a WRC and ORC that are at least as good as or even better than prior art products (including the Chen product) with regard to the water retention characteristics and the strength of that retention. This is true even though the products of the present invention may have a higher lignin concentration than products made using conventional processes and are dried (and the same amount as the Lundberg patents products).
- the highly refined cellulose microfiber product of the present invention derived from parenchymal cell material. These products are sometimes referred to herein as "exclusively parenchymal cell wall structures.” This is indicative of the fact that the majority source of the material comes from the cell structures of the plants that are parenchymal cells.
- the HRC microfibers of the invention are not produced by mild treatment of the leaves, stems, etc. of the plants (which are not only parenchymal cell wall structures, but have much more substantial cell structures). This does not mean that any source of citrus or beet cells and fibers used in the practice of the present invention must be purified to provide only the parenchymal cells.
- the relative presence of the more substantive cells from leaves and stems will cause approximately that relative proportion of cell or fiber material to remain as less effective material or even material that is not converted to HRC, but will act more in the nature of fill for the improved HRC microfibers of the present invention. It may be desirable in some circumstances to allow significant portions of the more substantive cells and fibers to remain or even to blend the HRC (citrus or beet parenchyma based) product of the present invention with HRC fibers of the prior art to obtain particularly desired properties intermediate those of the present invention and those of the prior art.
- the more substantive cells and fibers may be present in weight proportions of up to fifty percent (50%).
- the unexpected properties and benefits of the HRC materials of the present invention derived from the mild refinement of cells and fiber from citrus and beet by-product are the fact of the HRC fibers, the stability of HRC fibers from parenchymal cells, the high water retention properties, the strength of the water retention properties of the fibers, the ability of the HRC fibers to retain water (moisture) even when heated, the ability of the HRC fibers to retain water (moisture) on storage, and the ability of the HRC fibers to retain moisture in food stuff without promoting degradation, deterioration or spoilage of the food as compared to food stuff with similar concentrations of moisture present in the product that is not bound by HRC fibers.
- the ability of the fiber materials of the present invention to retard moisture migration is also part of the benefit.
- This retarded water migration and water activity of water retained or absorbed by the fibers of the invention may be related to the previously discussed binding activity and binding strength of water by the fiber.
- the materials of the invention provide significant benefits in this regard.

- An additional unexpected property is for the end processed product to have similar rheology curves as other common hydrocolloids, such as xanthan gum.

- Cohesive, machinable doughs which can be sheeted, stretched, and cut into pieces may be produced at room temperature when the doughs possess a high content of wheat or other gluten-containing flour.
- the baking of conventional wheat-based doughs into crackers provides a lamellar structure with generally uniform small cells and a tender, mealy, leavened texture. Upon mastication, the conventional crackers generally disperse more rapidly than does a chip. They do not provide a crunchy texture and a sensation of breaking into pieces with low molar compaction before dispersion as does a chip. Additionally, crackers are generally dockered to prevent pillowing and to provide a generally flat bottom surface and a blistered top surface.
- Oyster or soup crackers and snack crackers which have a pillowed appearance may be produced from wheat-based doughs by the elimination of dockering holes. However, these products still possess a leavened, tender, mealy texture and a cracker appearance, rather than a crisp, crunchy chip-like texture and chip-like appearance.
- Filled baked crackers or snacks obtained by needle injection of fillings into hollow expanded snacks made from wheat flour are disclosed in U.S. Patent No. 4,209,536 to Dogliotti, U.S. Patent No. 4,613,508 to Shishido, U.S. Patent No. 4,752,493 to Moriki, and U.S. Patent No. 5,000,968 to Szwerc et al. Production of a chip-like snack having surface bubbles and surrounding crisp, thin regions is not disclosed in these patents.
- the doughs are formulated and processed to retain a puffed or pillowed shape after piercing of the baked/hollow piece.
- a cellular structure is obtained by the use of egg white in the shell of the pastry product of U.S. Patent No. 4,209,536 to Dogliotti.
- hard dough biscuits are prepared by baking a dough having 10-30 parts by weight of sugar, 10-25 parts by weight of edible fat or oil, 1.5-4.0% leavening agent, and 20-35 parts by weight of water per 100 parts by weight of cereal flour to obtain a degree of leavening of at least 280%.
- the baked hollow expanded snacks in the form of a figure such as an animal or vehicle of U.S. Patent No. 4,752,493 to Moriki are produced from a farinaceous raw mixture.
- the raw mixture is prepared by mixing from 60-95 parts by weight of at least one low swelling-capacity farinaceous material and 40-5 parts by weight of at least one high swelling-capacity farinaceous material.
- the low swelling-capacity material may be a non-glutinous cereal such as wheat, rye, maize, non-glutinous rice, sago, sorghum, triticale, millet and beans, or starches separated from these sources.
- the high swelling-capacity material may be potato, taro, tapioca, arrowroot, sweet potato, glutinous rice, waxy corn, or starches derived from these sources having their cell walls broken.
- the farinaceous raw mixture is partly gelatinized prior to rolling into a smooth sheet by the addition of hot water or by the action of steam, so as to raise the temperature of the farinaceous raw mixture to 65°C to 90 0 C.
- Moriki upon baking, the starch in the surface of the dough pieces is gelatinized, thereby forming a skin having good gas-holding capacity and excellent stretchability. Water and volatile materials in the dough pieces push the skin outward upon heating, so that the dough pieces expand and are internally split into two layers or shells, forming a hollow space therebetween.
- the filled crackers of U.S. Patent No. 5,000,968 to Szwerc et al. are produced from a dough containing proteolytic enzymes.
- the enzymes hydrolyze proteins of the flour, which relaxes the dough and thereby permits a hollow center to be formed, rather than a cellular center, as the cracker expands under the influence of the leavening agent during baking. This, it is disclosed, strengthens the shell of the cracker and permits the cracker to be filled by means of an injection needle piercing the surface of the cracker.
- a standard recipe for a baked good known as a cracker includes at least the following as a non-limiting example: 3Og Active dry yeast
- the recipe calls for 70-90% by weight flour, 2-8% yeast, 0-10% sugar, 0- 8% salt, 0.005 to 2% consumable oil, 5-30% water and 0-5% flavoring or seed additive.

- wet materials Prior to drying, the wet materials need to be back mixed (that is wetter materials are added to the drier materials to facilitate drying of the wetter materials) with the dry materials (backmix ratio was 2 parts dry to 1 part wet) and a total of 6 lbs (2.6 kg) of wet feed was put in the batch style dryer.
- backmix ratio was 2 parts dry to 1 part wet
- a total of 6 lbs (2.6 kg) of wet feed was put in the batch style dryer.
- Pilot scale Flash drying trials were performed using a Carrier Vibrating Equipment (Louisville, KY) Tornesh dryer. Prior to drying, the wet materials (dispersed orange pulp, as from Example 2) were to be back mixed with the dry materials, again orange pulp from Example 2 (backmix ratio was 2 parts dry to 1 part wet) and a total of 30 lbs (13 kg) of 50% moisture wet feed was put in the dryer- Dry products were attained having functionality that was similar to the wet feed materials.

- a reduced fat shortening was made by adding Citri-FiTM 200 FG citrus fiber coprocessed with guar gum from Fiberstar, Inc., water, and vegetable shortening. The water level used was both three and six times the weight of Citri-FiTM and one half of the shortening was replaced with citrus fiber and water combination.
- Test 1 contained 100% vegetable shortening.
- Test 2 contained shortening at 50% and the balance being Citri-FiTM 200 FG (citrus fiber, guar gum) and water at 6 times the weight of fiber.
- Test 3 contained shortening at 50% and the balance being Citri-FiTM 200 FG (citrus fiber, guar gum) and water at 3 times the weight of fiber. All tests were conducted at 75°F with five replicates. The spreadability of the spreads were evaluated using a texture analyzer available from Texture Technologies with a spreadibility rig (TA-425 TTC) to measure the cohesive and adhesive forces of the spreads. The test results are shown in Table 1.
- a & B Denote groupings that are not statistically different from each other.
- Table 1 Cohesive and adhesive forces as measured by a texture analyzer of a 100% vegetable shortening compared to 50% shortening and balance being Citri-FiTM 200 FG (citrus fiber, guar gum) and water at 6 times the fiber weight (Test 2) and 3 times the fiber weight (Test 3).
- the spreadability results from Table 1 show that a 50% shortening spread can be made with very similar spreadability to a 100% shortening product.
- the adhesive and cohesive forces can be adjusted depending on the amount of water used along with the citrus fiber. In this example, if water is used at three times the weight of the citrus fiber, guar gum, then the spread had more adhesive and cohesive forces and was more firm. Whereas if water is used at six times the weight of the citrus fiber, guar gum, then the spread had less cohesive and adhesive forces and was slightly less firm.
- EXAMPLE 12 Another test was conducted by adding Citri-FiTM 200 FG (citrus fiber, guar gum), water, to a low trans roll-in, commonly used in the production of Danish, available from Bunge. Once again various water levels were used to evaluate the differences of water levels but another variable of the amount of roll-in replaced was also evaluated. The amount of roll-in replaced was 33% and 50%. Once again the cohesive and adhesive forces were measured using a texture analyzer. Test 4 contained the low trans roll in at 100%. Test 5 contained the low trans roll in at 66% and the remaining being fiber and water at six times its weight. Test 6 contained the low trans roll at 50% and the remaining being fiber and water at 3 times the weight of fiber. Test 7 contained low trans roll in 50% and the remaining being fiber and water at 6 times the weight of fiber. The test results are shown in Table 2.

- Test 10 contained margarine roll-in at 50% and the balance being Citri-FiTM 200 FG (citrus fiber, guar gum) and water at 6 times the weight of fiber.
- the test results shown in Table 3 suggest that with this margarine roll-in, a water level of 6 times the weight of fiber may be higher than what is needed to make a reduced fat roll-in with equivalent spreadability compared the full fat control.
- Example 11 and in Example 12 we showed that the by adding water at three times the weight of the Citri-FiTM 200 FG (citrus fiber, guar gum) can make the reduced fat spread more thick compared to the control spread.
- an alternative way to make a more cohesive and adhesive texture is to start with a fat that has a harder texture and to add the 6 times water and fiber to this starting mixture.
- a Swede Gold shortening was used along with Citri-FiTM 200 FG (citrus fiber, guar gum) and water at 6 times the fiber weight.
- the texture of this combination was compared to the control roll-in as shown in Test 8.
- the spreadability of the spreads was evaluated using a texture analyzer available from Texture Technologies with a spreadibility rig (TA-425 TTC) to measure the cohesive and adhesive forces of the spreads.
- Table 4 Cohesive and adhesive forces as measured by a texture analyzer of control margarine roll in and reduced fat margarine roll-in spread.
- Test 8 contained 100% margarine roll-in.
- Test 11 contained a hard fat roll-in that was reduced by 50% with Citri-FiTM 200 FG (citrus fiber, guar gum) and water at 6 times the fiber weight.
- EXAMPLE 15 A control Danish made with 100% margarine roll-in was compared to a Danish made with a reduced fat roll-in that was prepared and compared to a 66% roll-in and balance being Citri-FiTM 200 FG (citrus fiber and guar gum). The water level used was six times the weight of the fiber. Roll in is typically used in a Danish to produce the flaky and layered texture that is desired for a Danish or croissant. Thus, the test with the reduced fat roll in to see if the layered texture and flakyiness could be maintained when the roll-in had a percentage replaced with Citri-FiTM 200 FG (citrus fiber and guar gum) and water. The following formula was used for the control and reduced fat Danish.
- Table S Formula used in the production of a control and reduced fat roll-in Danish.
- Citri-FiTM 100 citrus fiber from Fiberstar, Inc. was used in testing a 50% reduced fat shortening cake formula.
- the amount of Citri-FiTM 100 citrus fiber used was 0.125 times the weight of shortening removed from the formula and the amount of water was 7 times the weight of Citri-FiTM 100 citrus fiber.
- the nutritional analysis for the control and test cake formula was generated using Genesis software from Esha Research (Salem, OR). The cake was made according to the formula shown in Table 1:
- Step l granulated sugar 110.1 110.1 cake shortening 52.9 26.5
- Citri-FiTM 100 0 5.3 water 0 15.9

- Citri-FiTM citrus fiber can be used to replace fat, shortening, and oil and maintain a product with similar eating qualities to the control.
- EXAMPLE 17 REDUCED FAT BREAD Bread was made according to the formula shown in the following table where 100% of the shortening was placed in the formula. Citri-FiTM 200 citrus fiber and guar gum was used in this test.
- Citri-FiTM 100 citrus fiber was used to make a 50% reduced fat shortening in a sweet roll according the formula in the following table.
- EXAMPLE 19 REDUCED FAT MUFFINS
- expanded cell wall materials can also be used to reduced the fat in an oil.
- the resultant reduced fat oil has a similar consistency as a standard oil and when this is added into a formula, the resultant product has very similar eating qualities compared to the full fat oil.
- Citri-FiTM 100 citrus fiber was used to reduce oil in a muffin formula.
- a Multi-Foods muffin mix (# 44812) was used in this testing and the control formula was followed according to the instructions on the bag. The formula used for the muffins is shown below:
- a cracker was made using Citri-FiTM 100FG ® fiber additive available from Fiberstar
- Table 1 Example cracker formulation with Citri-FiTM 100 FG.
- the crackers made using the Test 1 and Test 2 formulations were significantly stronger compared to the control. Although all crackers have similar eating qualities and taste, it was apparent that the level of Citri-FiTM fiber additive could be used to adjust the strength of the crackers up or down. For example, in Test 1 with 1.5% Citri-FiTM 100 FG fiber additive, the strength was noticeably increased compared to Test 2 that had a reduced 0.75% of the flour weight of Citri-FiTM fiber additive 100 FG, while both were significantly stronger compared to the control.
- EXAMPLE 21 A pasta product was made using Citri-FiTM 100FG ® fiber additive available from Fiberstar Inc. at levels of 0.75% and 1.5% of the flour weight. An additional four parts of water per part of Citri-FiTM fiber additive were added to maintain a similar dough consistency as the control. Example formulations are shown in Table 1. Once the dough was mixed, it was formed into the shape of pasta and baked at 400° F for 5 minutes until brown and crisp.
- Citri-Fi 200 ® fiber additive available from Fiberstar, Inc. at a level of 4.27% of the flour weight.
- An additional six parts of water per part of Citri-FiTM fiber additive were added to maintain a similar dough consistency as the control.
- Example formulations are shown in the following table. Once the dough was mixed, it was formed into the shape of tortilla chip and fried in frying oil at 400° F. The Citri-Fi fiber additive tests were noted to be stronger compared to the control.
- the 3-Point Bend test is performed using an adjustable bridge platform (TA- 92) and a rounded end knife blade probe (TA-42).
- the bridge platform has two rails and for this evaluation the rails were spaced 1-inch apart.
- the cracker sample is supported by the two rails at each edge.
- the probe contacts the sample along a center line and continues to descend through the cracker measuring the force it takes to break it.
- the pre-test speed was 3.0 mm/second.
- the rounded end knife blade traveled at that speed until the Texture Analyzer's surface detection feature detected 10 grams of force (trigger) and which point it traveled 15.0 mm through the cracker at a speed of 1.0 mm/second.
- the probe withdrew at a speed of 10.0 mm/second. Fourteen to fifteen crackers were tested for each variable.
- the crackers containing 1% Citri-Fi 100 FGTM additive took significantly more force to break. The distances to peak were not significantly different between variables. This means it is taking a similar distance to affect breakage. One other trend that was noticed during the testing was the number of stress fractures before the final break. Control had the highest number. The presence of Ci tri Fi 100TM additive in the cracker appeared to reduce the number of stress fractures. Sensory evaluation did not pick up any flavor differences between the samples. All samples were crisp. The 1.0% Citri-Fi IOOFGTM additive sample was slightly more dense and tough than control.
- the meat was placed in a mixer, and then half of the treatment solution was added and mixed for about 30 seconds at speed 1.
- the bowl was scraped, tKen the remaining treatment solution was added while mixing for four (4) minutes at speed 1.
- the pH of the treated ground meat was measured.
- the meat paste was then placed in aluminum cups or loaf pans.
- the . weight was standardized at 400 grams per cup.
- the cups were each sealed with a plastic foil and the meat was cooked in a baking oven, until the core temperature reached 72.2C (162F).
- the total cooking time was about 1.5 hours at HOC (230F).
- the cooked product was left to cool for about 1 hour at room temperature. After cooling, the meat was dried in absorbent paper then weighed. Examples for using expanded fiber products to replace binders in meats

These results from these experiments are shown in Table 4. Table 4: Results from using various levels and types of Citri-Fi citrus based fibers and sodium tripolyphosphate.
- Test 1 For the first test (Test 1), the same procedure as outlined above was followed except there no phosphates or carrageenan and replaced with an expanded fiber product. 0.5% Citri-Fi 100M40 citrus fiber was added dry after the initial mixing for 8 minutes and mixed for an additional 4 minutes. Cured, cooked and chilled as above. The Test 1 result had 3.3% purge after cooking and chilling. The product looked good (except for small air holes), had no evidence of fiber, sliced well, was firm and tasted good.

MOISTURIZING COMPOSITION FOR PROTEIN MATERIALS RELATED APPLICATIONS DATA
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
This invention relates to food products, including vegetable protein products, baked products, and animal protein-containing food products and preparations, more specifically to food products having improved moisture retention and shelf-life. BACKGROUND OF THE ART
Published articles from FDA, American Heart Association, and Harvard all tie a link between trans fats and saturated fats with increased LDL (bad cholesterol) and thus, heart disease. Beginning in January 2006, FDA will require food companies to list the amount of trans fatty acids on their labels. To lower the trans fat levels in foods, shortening suppliers have introduced low trans fat shortenings.. However, within the newer compositions that have been provided for low trans shortenings there is an increase in the amount of saturated fats. In a typical shortening the saturated fat goes from 26% in standard shortening to 40% in low trans shortenings. Therefore, while shortening suppliers are trying to offer a healthier product a product with lower the trans fat, there is a trade-off with the increased saturated fats that raises concerns with regard to the saturated fat ingredient. For companies concerned about keeping trans fats off their labels, a company that switches to a low trans/higher saturated fat shortening for certain high fat products, e.g. cakes, donuts, etc, will still need to label an amount of trans fatty acids and also indicate a higher level of saturated fats.
U.S. Patent Nos. 6,251,458; 5,487,419; 4,923,981; 4,831,127; 4,629,575, Weibel) relates to material additives. US 4,923,981 relates more to issues of fat replacement describes using expanded parenchymal cell cellulose (PCC) for fat reduction. However, this Weibel patent specifically talks about making PCC through a process that uses alkaline or acid conditions. Additionally, the patent does not give a method for drying the product nor enable using a dried and expanded PCC, whereas the product used in the present technology is in a dried form.
U.S. Patent No. 5,964,983 (Dinand) uses alkaline and/or acid conditions to make their microfibrillated cellulose. Dinand discloses the use of alkaline and/or acid
conditions to make microfϊbrillated cellulose, and also does not disclose the combination of water, fiber and shortening directly together to make a reduced fat shortening, oil, margarine, or butter.
U.S. Patent No. 5,766,662 (Inglett) describes replacing fat, but specifically states that the fat replacement product is the product made according to his invention is a product made through the combination of mechanical and chemical processes. Additionally, the dry product he makes needs to be sheared in a shearing device, i.e., a high speed blender, before the product can be used for fat replacement. This work does not disclose the direct combination of water, fiber, and shortening together to make a reduced fat shortening, oil, margarine, or butter.
In considering the Weibel patents (6,251,458; 5,487,419; 4,923,981; 4,831,127; and 4,629,575), only patent 4,923,981 appears to have relevant disclosure with respect to fat replacement using expanded parenchymal cell cellulose (PCC) for fat reduction. The resulting product is not a reduced fat shortening, spread, roll-in, butter, or oil, but is a compounded product. Additionally, this patent specifically talks about making PCC through a process that uses alkaline or acid conditions. Weibel also does not give a method for drying fiber, which is a very significant and important step in the process of providing a highly refined cellulose fiber, and especially a highly refined cellulose fiber from citrus pulp and material with high parenchymal content. Weibel does not disclose using a dried and expanded PCC
Several other prior art sources (US Patent #'s: 5,658,609, 5,190,776, 5,360,627, 5,439,697, 6,048,564) state the concept of a reduced fat shortening, margarine, spread, roll-in, butter, or oil but they are made with either combinations of modified starches, gums, emulsifϊers, or combinations of other ingredients as opposed to the object of this invention is to do the fat reduction using an expanded cell wall cellulose and water.
Published US Patent Application No. 20020012722 describes a ready-to-eat food having, at a 60% confidence level, a lower taste value greater than -8.00; a water activity of less than 0.90; and comprising, on a single reference serving basis: a.) an amino acid source that provides at least 19% of the total caloric value of said food; b.) a fat that provides less than 30% of the total caloric value of said food; and c.) a carbohydrate that provides the balance of the total caloric value of said food and at least about 2.5 grams of dietary fiber.
Animal protein-containing food products, including whole meat, ground or chopped meat, pureed meat and deboned whole meat products, such as poultry, ham, roast beef, frozen fish filets, shrimp, scallops and fine paste sausages, contain moisture in the form of natural water content and, in some cases, water that is added during processing. The water content of such products has a pronounced effect on both product weight and product sensory qualities. Various additives, such as, for example, polyphosphates, starches, gums, and carrageenans are used as to enhance the moisture retention of such food products. Polyphosphates are the most commonly used moisture retention additive, but may undesirably increase the phosphorus content of food processing effluents.
U.S. Patent No. 7,001,630 (Bender) describes a method for treating meats to retain moisture by injecting or otherwise adding alkali metal silicates into the meat. Injection of marinades into meats is well known (as described in US Patent No. 5,431,937), but the moisture content is not retained in the product by effective means.
U.S. Patent No. 4,031,267 (Berry et al.) describes an expanded protein product containing up to about 35% by dry weight of a fat or oil that can be prepared by forming a mixture comprising a proteinaceous material, fat or oil, and minor amounts of a finely divided non-proteinaceous and non-farinaceous filler material, hereinafter referred to simply as filler material.

DETAILED DESCRIPTION OF INVENTION AND PREFERRED EMBODIMENTS
The present technology enables the addition of Highly Refined Cellulose materials (as defined and described herein) as additives to specific classes or groups of food products to enhance physical and taste/feel properties of food materials without adding unnecessary amounts of harmful or less desirable additives such as fats, shortentings, sugars, and artificial chemical additives to the food products.
Published articles from FDA, American Heart Association, and Harvard all tie a link between trans fats and saturated fats with increased LDL (bad cholesterol) and thus, heart disease. Beginning in January 2006, FDA will require food companies to • list the amount of trans fatty acids on their labels. To lower the trans fat levels in foods, shortening suppliers have introduced low trans fat shortenings. However, within the newer compositions that have been provided for low trans shortenings there is an increase in the amount of saturated fats. In a typical shortening the saturated fat goes from 26% in standard shortening to 40% in low trans shortenings. Therefore, while shortening suppliers are trying to offer a healthier product a product with lower the trans fat, there is a trade-off with the increased saturated fats that raises concerns with regard to the saturated fat ingredient. For companies concerned about keeping trans fats off their labels, a company that switches to a low trans/higher saturated fat shortening for certain high fat products, e.g. cakes, donuts, etc, will still need to label an amount of trans fatty acids and also indicate a higher level of saturated fats.
U.S. Patent Nos. 6,251,458; 5,487,419; 4,923,981; 4,831,127; 4,629,575, Weibel) relates to material additives. US 4,923,981 relates more to issues of fat replacement describes using expanded parenchymal cell cellulose (PGC) for fat reduction. However, this Weibel patent specifically talks about making PCC through a process that uses alkaline or acid conditions. Additionally, the patent does not give a method for drying the product nor enable using a dried and expanded PCC, whereas the product used in the present technology is in a dried form.
U.S. Patent No. 5,964,983 (Dinand) uses alkaline and/or acid conditions to make their microfibrillated cellulose. Dinand discloses the use of alkaline and/or acid conditions to make microfibrillated cellulose, and also does not disclose the combination of water, fiber and shortening directly together to make a reduced fat shortening, oil, margarine, or butter.
U.S. Patent No. 5,766,662 (Inglett) describes replacing fat, but specifically states that the fat replacement product is the product made according to his invention is a product made through the combination of mechanical and chemical processes. Additionally, the dry product he makes needs to be sheared in a shearing device, i.e., a high speed blender, before the product can be used for fat replacement. This work does not disclose the direct combination of water, fiber, and shortening together to make a reduced fat shortening, oil, margarine, or butter.
In considering the Weibel patents (6,251,458; 5,487,419; 4,923,981; 4,831,127; and 4,629,575), only patent 4,923,981 appears to have relevant disclosure with respect to fat replacement using expanded parenchymal cell cellulose (PCC) for fat reduction. The resulting product is not a reduced fat shortening, spread, roll-in, butter, or oil, but is a compounded product. Additionally, this patent specifically talks about making PCC through a process that uses alkaline or acid conditions.
A highly refined cellulose material is a composition of matter is used in a cooked cracker product comprising a) 0.05%-5% by total weight highly refined cellulose product defined by a fiber material that has a total dietary fiber (TDF) content greater than 30% as measured by AOAC 991.43 and a water holding capacity greater than five parts water per part fiber as measured by AACC 56-30 followed literally or with modifications as listed in the specifications and is less than 90% soluble fiber, b) proteinaceous grain product, and c) fat or oil used as an ingredient in the preparation of non-leavened or leavened crusted product that is prepared by baking, frying, broiling or other heated-prepared flour or grain based food products such as chips, crackers, the precooked mass comprising 0.05%-5.0% by weight of highly refined cellulose fiber, 2-20% by weight animal consumable oils or fats, 30-92.75% of flour or grain and 5-45% by weight of water. The final product has increased crust strength and resistance to cracking and rigid crumbling.
A problem that continues to exist with certain types of foods, namely relatively flat (e.g., having an aspect ratio of at least 5: 1, or 7:1, such as crackers,
chips (e.g., corn rice, vegetable, rice, wheat or other organic edible protein-based sources), wafers, and the like (such as those products sold under names such as Pringles® chips, Dorito® chips, Wheat Thins® crackers, Ritz® crackers, Keeblers® crackers, Triskets® wafers, and the like), pretzels, taco shells, graham crackers, dried noodles and pasta in its various forms, is the susceptibility of the products to be damaged during storage, packaging, shipping, package handling and the like. The damage to the product (hereinafter generically referred to as a cracker or breakable flour containing product, as opposed to a cracker, chip, wafer, pretzels, taco shells, graham crackers, noodles and pasta reduces the appearance, marketability, utility and value of the final cracker or breakable flour containing product. Especially where the products have fragile surface constructions, such as bubbles, which appear in typical crackers or breakable flour containing products, the surface o the bubbles (which are much thinner than the entire thickness of the cracker) is even more subject to damage that reduces the appearance, the functionality (e.g., the crackers or breakable flour containing products break more easily when put under stresses of use) and value of the cracker or breakable flour containing products. The presently disclosed technology establishes that the addition of highly refined cellulose material (fibers, fibrils, fibroids, and particles) into the recipe mixture from which the cracker product is formed and the cracker or breakable flour containing products are cooked, the strength of the product surface or crust is improved. This is effected especially when at least 0.05%, at least 0.25%, at least 0.50%, at least 0.75%, at least 1.0%, at least 1.25%, at least 1.50% up to about 5% of the wet weight of the recipe mixture comprises the highly refined cellulose material. A preferred range should be identified for each recipe, but will still reside within the range shown, and may be more narrowly expected within a range of 0.5% to 4.0% wet weight of the ingredients, or within a range of 0.75% to 3.0% wet weight of the ingredients. The exact mechanism or reason for this benefit is not understood, but has been evidenced by actual reduction to practice.
There are several distinct types of cracker or breakable flour containing products that are contemplated in the practice of the invention, the cracker, the chip, the wafer, pretzels, taco shells, graham crackers, dried noodles and pasta. All types may be broken down further with leavened and unleavened products, although with
one of the products, the chip, leavening is seldom used. Each of these cracker products has a crust component in which the outermost surface (at least initially after cooking) tends to be more oxidized or more stressed (e.g., browned, crisper, bubbled into a thinner exterior than the overall thickness of the cracker product, more brittle exterior layer component) than the interior of the cracker product. It is because of this stressing from the cooking process that the crust layer or most exterior layer of the cracker product tends to be more subject to damage. The addition of the highly refined cellulose fiber, as defined by the > 30% total dietary fiber and five times water holding capacity, product according to the present technology and especially the highly refined cellulose products developed and described herein that are derived from citrus pulp addresses and moderates this problem, providing a stronger crust that still retains the essential taste, feel, snap, brittleness and texture properties expected and desired in a crust of a cracker product. A highly refined cellulose material is used in a composition of matter is a cooked or uncooked edible mass that ordinarily has a recipe including eggs, egg whites, egg yolks or egg substitutes in a dry or undried form as from 0.5-30% by weight of the edible mass has the egg content reduced or replaced by a substitute material comprising from 0.05-10% highly refined cellulose and 2 — 50 parts by weight aqueous material per part of dry highly refined cellulose material added, preferably water. The final product may be based on any existing or future recipe which calls for about 1-30%, 1-15%, 1-12% or 2-10% of the total mass (either dry or wet) to comprise eggs, egg whites, egg yolks or egg substitutes. These products could include, by way of non-limiting examples, pastry, bread, pasta, dumplings, bagels, flat bread, wrappings, cakes, cookies, crusts, cracker, whole egg products, or any other product where eggs are added in a product comprising a) 0.05%-7% by total weight highly refined cellulose product defined by a fiber material that has a total dietary fiber (TDF) content greater than 20%, 25% or less than 30% as measured by AOAC 991.43 and a water holding capacity greater than three, four or five parts water per part fiber as measured by AACC 56-30 followed literally or with modifications as listed in the specifications and is less than 50%, less than 75% or less than 90% soluble fiber, b) proteinaceous grain product, and with or without c) fat or oil used as an ingredient in the preparation of non-leavened or leavened product that is prepared
by boiling, steaming, baking, frying, broiling or other heated-prepared flour or grain based food products such as those listed above, the precooked mass preferably comprising 0.05%-5.0% by weight of highly refined cellulose fiber; 0, 1 or 2-20% by weight animal consumable oils or fats; 30-92.75% of flour or grain and 5-45% by weight of water and where egg component (a term herein defined as egg, egg white, egg yolk, or egg substituent) in the original recipe of from 1-8% total solids ingredients (wet or dry considered) being replaced or substituted in whole or in part by the technology of the present description . The final product has increased crust strength and resistance to cracking and rigid crumbling. A meat product (any whole, ground, boned or deboned animal protein product) comprises 0.005%-5% by total weight of a fiber material that has a total dietary fiber (TDF) content greater than 30% as measured by AOAC 991.43 and a water holding capacity greater than five parts water per part fiber as measured by AACC 56-30 and comprises less than 90% soluble fiber. The use of this type of composition allows for the reduction of all or a portion of sodium tripolyphosphate that is commonly used in meat products to maintain moisture, enabling the user to reduce the tripolysphosphate. concentration to less than 0.5% by total weight, less than 0.4% by total weight, less than 0.3% by total weight, less than 0.2% by total weight, less than 0.1$ by total weight, and less than 0.05% or les than 0.01% by total weight (down to 0% by total weight) of meat protein in the meat product.
A meat product may also comprise O.OO5%-5% (e.g., 0.010-4%, 0.05-4%, 0.80- 3%, and 0.05-5%) by total weight in the meat product, including moisture of a fiber material that has a total dietary fiber (TDF) content greater than 30% as measured by AOAC 991.43 and a water holding capacity greater than five parts water per part fiber as measured by AACC 56-30 and comprises less than 90% soluble fiber where all or a portion of the milk solids are reduced (e.g., less than 5% by total weight, less than 4% by total weight, less than 3% by total weight, less than 2% by total weight, less than 1% by total weight to 0% by total weight) using the fiber material.
Another meat product may comprise 0.05%-5% by total weight of a fiber material that has a total dietary fiber (TDF) content greater than 30% as measured by AOAC 991.43 and a water holding capacity greater than five parts water per part fiber as measured by AACC 56-30 and comprises less than 90% soluble fiber where all or a portion of the carageenan products are reduced (e.g., less than 5% by total weight, less
than 4% by total weight, less than 3% by total weight, less than 2% by total weight, less than 1% by total weight to 0% by total weight) using the fiber material.
A meat product comprising 0.05%-5% by total weight of a fiber material that has a total dietary fiber (TDF) content greater than 30% as measured by AOAC 991.43 and a water holding capacity greater than five parts water per part fiber as measured by AACC 56-30 and comprises less than 90% soluble fiber where all or a portion of the gums and other water binders in the meat are reduced (e.g., less than 5% by total weight, less than 4% by total weight, less than 3% by total weight, less than 2% by total weight, less than 1% by total weight to 0% by total weight) using the fiber material.
A highly refined cellulose material is a composition of matter is defined in variously in the art by way of its properties. For example, copending US Patent application Serial No. 10/303,256 describes HRC fibers as cellulosic mass from organic mass derived from agricultural plants comprising a highly refined cellulose (HRC) having a lignin concentration of at least 1% by weight and a water retention capacity of at least about 20 g H2CVg dry HRC, possibly an oil retention capacity of at least about 10 g/g dry HRC, and possibly further having an oil retention capacity of at least about 10 g/g dry HRC and or a Langmuir surface area of at least about 7 m2/g. The HRC may have an average pore diameter of at least about 5 angstroms and may have a Langmuir surface area of at least about 7 m2/g. That reference is incorporated herein in its entirety. Published U.S. Patent Applications Nos. 20050274469; 20050271790; 20050074542; 20040086626; and 20030116289 disclose highly refined cellulose materials.
HRC material may alternatively be described as a fiber material that has a total dietary fiber (TDF) content greater than 30% as measured by AOAC 991.43 and a water holding capacity greater than five parts water per part fiber as measured by AACC 56-30 followed literally or with modifications as listed in the specifications and is less than 90% soluble fiber.
The HRC may, according to the practices of the technology described herein, be used as ah ingredient in the preparation of non-leavened or leavened, vegetarian or meat-containing product that is prepared by baking, frying, broiling or other heated- prepared methods, the precooked mass comprising 0.05%-5.0% by weight of highly refined cellulose fiber or 0.01% - 10% by total weight of the food product of the fiber
gum combination. The combination of the fiber and gum is preferably made in advance of the mixture of the fiber/gum composition to the food product, which in part explains the relatively wide range of weight additions of these materials that is possible. When the fiber ad gum materials are precombined, in the 5-50% range described above, preferably in a
Highly refined cellulose fibers may be produced with a wide range of properties and by various distinct processes. For the purpose of this patent application we are defining highly refined cellulose fibers as those with a total dietary fiber (TDF) content greater than 30% as measured by AOAC 991.43 and a water holding capacity (WHC) greater than five parts water per part fiber as measured by AACC 56-30 followed literally or with the following modifications; namely, 1) using shearing to hydrate the fiber mass, and/or 2) only using the first stage steps (1-4) of AACC 56-30 to find the approximate WHC and using this as the final WHC value, and/or 3) determining the final or approximate WHC value at 2-10% solids instead of 10% or using 2.5 g of fiber mass for the sample size instead of 5 g as the procedure calls for. The varying products can produce highly refined cellulose products with a wide range of properties that are based in part upon both on the starting organic mass containing fibers and the process steps, parameters and reagents. The underlying objective of the various processes is to take fibrous and or cellular mass (usually from agricultural products, especially flora (plants), and to reduce the structure in maximum ways. For example, as the original mass is sheared, shredded, exploded, disrupted or otherwise reduced from a complete cellular structure to fibrils, fibers, particles and other structures that form parts of the original organic mass. Various references that teach such processes and resulting expanded, highly refined cellulose materials include but are not limited to U.S. Patent Nos. 5,766,662; 5,342,636; 4,957,599; and copending U.S. Patent Applications Serial No. 10/969,805, filed 20 October 2004, "HIGHLY REFINED CELLULOSIC MATERIALS COMBINED WITH HYDROCOLLOIDS/' which is a continuation-in-part of U.S. Patent Application Serial No. 10/288,793, filed Nov. 6, 2002, titled "HIGHLY REFINED FIBER MASS, PROCESS OF THEIR MANUFACTURE AND PRODUCTS CONTAINING THE FIBERS . "
It is important to note the difference ion the practice of the present technology of the term "highly refined cellulose" product as compared to the more conventional material referred to as "dietary fiber." Many teachings of baked
products including cracker products include the use of dietary fiber as one method of improving dietary or nutritional benefits in the baked good. Dietary fiber generally refers to the use of bulk fiber material, usually in its less processed state (e.g., dried but not highly sheared) so that the fiber remains substantially intact and even cell wall structure and cell morphology can be readily seen under microscopic examination (e.g., 4OX to 500X examination).
Published U.S. Patent Applications Nos. 20050274469; 20050271790; 20050074542; 20040086626; and 20030116289 disclose highly refined cellulose materials. Prior art results according to the Chen patents were WRC values were measured for both the aqueous HRC gel and dried HRC powder using a process that used NaOH concentrations ranging from about 0.004 to 0.025 g NaOH/g water. The WRC values for both the HRC gel and HRC powder were in the range of about 20 to at least about 56 g H2CVg dry HRC, depending on the concentration of the alkaline solutions as measured by AACC 56-10 at varying solids content, which were typically less than 5% and most commonly at 1%. Maximum WRC values for the gel of at least about 56 g H2OZg dry HRC were obtained with a NaOH concentration of about 0.007 g NaOH/g H.sub.2O. Drying the HRC gel resulted in a reduction of about three (3) to 15% in WRC, which may be attributed to structural damages such as recrystallization caused by dehydration. However, the HRC powder also exhibited high WRC values, having a maximum WRC value of at least about 56 g H2OZg dry HRC at a NaOH concentration of about 0.007 g NaOHZg H2O. Compared with WRC values for even earlier prior art HRC products of 3.5 to 1O g waterZg dry powdered cellulose reported by Ang and Miller in Cereal Foods World, Multiple Functions of Powdered Cellulose as a Food Ingredient, Vol. 36 (7): 558-564 (1991), it was shown that both the HRC gel and powder of the Chen Patents had a much higher water-holding capacity than prior art materials known at the time of the invention.
Determination of Water-Retention Capacity (WRC) and Oil-Retention Capacity (ORC) WRC is a measure of the amount of water retained under standard centrifuge. The WRC values for both aqueous HRC gel and freeze-dried HRC were determined in accordance with Method 56-10 of the American Association of Cereal Chemists (AACC), except the water holding capacities were measured in a 1%
hydrated state. In the ORC (oil retention capacity) test, the same procedure was used except oil was used instead of water.
Determination of Pore Size and Microsurface Area Both the pore size and the microsurface area of freeze-dried HRC samples were measured using a Micromeritics™ 2000 from Micromeritice Instrument Co. The test sample was weighed with a precision of 0.0001 g. In all cases, the test sample weight was more than 100 mg to reduce the effect of weighing errors. At 85°C and 6 mmHg vacuum, the sample was degassed, and moisture and other contaminants were removed. The degassed sample was analyzed in a nitrogen gas environment. Average pore diameter, BET surface area and Langmuir surface area were measured. The BET surface area values were determined by calculating the monolayer volume of adsorbed gas from the isotherm data. The Langmuir surface area values were obtained by relating the surface area to the volume of gas adsorbed as a monolayer. Results and Discussion - Pore Size and Surface Area Average pore size is a measure of openness of the HRC structure. The average pore size increased rapidly as NaOH concentration was increased to 0.007%, then slowly with further increase in NaOH concentration. The surface area reached a maximum value at 0.007% NaOH, which also coincides with the maximum WRC discussed above. The decrease in surface area after the maximum value seems to suggest an increase in the ratio of large pores to small pores, which may contribute to the decrease in total surface area. In one embodiment, the processes of the Lundberg Application removes lignin to a sufficient degree or substantially inactivates it such that undesirable fiber clumping does not occur There is not a large apparent difference in terms of WHC/viscosity between the two products (the Chen product and the product of the Lundberg Application) in a wet form, but there is a significant and commercially and technically important difference between the products/processes is that 1) Chen never provided a method for drying the gel product or 2) rehydrating the dry product. Additionally, 3) the present process for citrus has no required chemical treatment and does not need any mechanical treatments to produce a dry product that rehydrates to a high WHC/viscosity gel. Additionally, there is less concern about all the surface area, and pore size measurements.
It is desired that the highly refined cellulose fiber materials used in the practice of the present technology have the following properties. The HRC materials should provide a viscosity of at least 200 cps (preferably at least 300 cps) at 2OC in a
concentration of 3% in deionized water after mild stirring for 4 hours, a water retention capacity of at least 8X the dry weight of fiber (preferably at least 10X, at least 15X and at least 20X), which may also be determined by filtering saturated fiber mass, draining excess water (e.g., under mild pressure of 50g/10cm for three minutes), weighing the drained wet fiber mass, then dehydrating the drained mass (to less than 5% water retention/weight of the fiber) and weighing the dried product to determine the amount of absorbed water removed. This latter method is less preferred, but can address the issue that drying of fibers often changes their physical properties, and particularly dried fibers (unless additionally sheared) often lose WRC after drying.
A highly refined cellulosic material (e.g., cellulose, modified celluloses, derivatized celluloses, hemicellulose, lignin, etc.) product can be prepared by generally moderate treatment and still provide properties that are equivalent to or improved upon the properties of the best highly refined cellulose products produced from more intense and environmentally unfriendly processes. Fruit or vegetable cells with an exclusively parenchymal cell wall structure can be treated with a generally mild process to form highly absorbent microfibers. Cells from citrus fruit and sugar beets are particularly available in large volumes to allow volume processing to generate highly refined cellulose fibers with both unique and improved properties. These exclusively parenchymal microfibers (hereinafter referred to as EPM's) have improved moisture retention and thickening properties that enable the fibers to provide unique benefits when combined into edible products (e.g., baked goods, liquefied foods, whipped foods, meats, meat fillers, dairy products, yogurt, frozen food entrees, ice cream, etc.) and in mixtures that can be used to generate edible food products (e.g., baking ingredients, dehydrated or low hydration products).
A new process for making HRC cellulose from parenchyma cell wall products, e.g. citrus fruit and sugar beets by-products, is performed in the absence of a hydroxide soaking step. This is a significant advance over the prior art as described by the Chen and Lundberg patents. Dinand, et al. (U.S. Patent No. 5,964,983) also recommends the use of a chemical treatment step in addition to bleaching. In the present invention we are able to attain higher functionality (measured as viscosity) compared to Dinand et al. even though we use less chemical treatment, which is likely due to the higher amount of shear and chemical energy we put into the materials. The product is able to display the same or improved water retention properties and
physical properties of the more strenuously refined agricultural products of the prior art, and in some cases can provide even higher water retention values, thickening and other properties that can produce unique benefits in particular fields of use.
General descriptions of the invention include a highly refined cellulose product comprising microfibers derived from organic fiber plant mass comprising at least 50% by weight of all fiber mass as parenchymal fiber mass, the highly refined cellulose product having an alkaline water retention capacity of at least about 25g HbO/g dry highly refined cellulose product and methods for providing and using these products. The highly refined cellulose product may have a water retention capacity of at least 50g HbO/g dry highly refined cellulose product.
Parenchymal cell walls refer to the soft or succulent tissue, which is the most abundant cell wall type in edible plants. For instance, in sugar beets, the parenchyma cells are the most abundant tissue the surrounds the secondary vascular tissues (xylem and phloem). Parenchymal cell walls contain relatively thin cell walls compared to secondary cell walls are tied together by pectin (Haard and Chism, 1996, Food Chemistry. Ed. By Fennema. Marcel Dekker NY ,NY) In secondary cell walls (xylem and phloem tissues), the cell walls are much thicker than parenchymal cells and are linked together with Iignin (Smook). This terminology is well understood in the art. As used in the practice of the present invention, the term "dry" or "dry product" refers to a mass that contains less than 15% by weight of fibers as water. The organic fiber mass comprises at least 50% by weight of fiber mass from organic products selected from the group consisting of sugar beets, citrus fruit, grapes, tomatoes, chicory, potatoes, pineapple, apple, carrots and cranberries. A food product or food additive may have at least 0.05 percent by weight solids in the food product or food additive of the above described highly refined cellulose product. The food product may also have at least about one percent or at least about two percent by weight of the highly refined cellulosic fiber of the invention.
A method for refining cellulosic material may comprise: soaking raw material from organic fiber plant mass comprising at least 50% by weight of all fiber mass as parenchymal fiber mass in an aqueous solution with less than 1% NaOH; draining the raw material and allowing the raw material to sit for a sufficient period under conditions (including ambient conditions of room temperature and
pressure as well as accelerated conditions) so that the fibers and cells are softened so that shearing can open up the fibers to at least 40%, at least 50%, at least 60%, or at least 70, 80, 90 or 95% of their theoretic potential. This will usually require more that 4 hours soaking to attain this range of their theoretic potential. It is preferred that this soaking is for more than 5 hours, and preferably for at least about 6 hours. This soaking time is critical to get the materials to fully soften. When such a low alkaline concentration is used in the soaking, without the set time, the materials do not completely soften and can not be sheared/opened up to their full potential. This process produces soaked raw materials; and the process continues with refining the soaked raw material to produce refined material; and drying the soaked raw material.
The process may perform drying by many different commercial methods, although some display improved performance in the practice of the present invention. It is preferred that drying is performed, at least in part, by fluid bed drying or flash drying or a combination of the two. An alternative drying process or another associated drying step is performed at least in part by tray drying. For example, fluid bed drying may be performed by adding a first stream of organic fiber plant mass and a second stream of organic fiber plant mass into the drier, the first stream having a moisture content that is at least 10% less than the moisture content of the second stream or organic fiber plant mass. The use of greater differences in moisture content (e.g., at least 15%, at least 20%, at least 25%, at least 40%, at least 50% weight-to- weight water percent or weight-to-weight water-to-solid percent) is also within the scope of practice of the invention. In the drying method, the water may be extracted with an organic solvent prior to drying. In the two stream drying process, the second stream of organic fiber plant mass may have at least 25% water to solids content and the first stream may have less than 15% water to solids content. These processes may be practiced as batch or continuous processes. The method may use chopping and washing of the cellulose mass prior to soaking.
Another description of a useful process according to the invention may include draining and washing the soaked raw material in wash water to produce washed material; bleaching the washed material in hydrogen peroxide to produce a bleached material; and washing and filtering the bleached material to produce a filtered material.
The drying of an expanded fiber material according to the invention may use room temperature or higher air temperatures that dry the expanded fiber product and
maintain the fiber material's functionalities of at least two characteristics of surface area, hydrogen bonding, water holding capacity and viscosity. It is also useful to use backmixing or evaporating to bring the organic fiber plant mass to a solids/water ratio that will fluidize in air in a fluid bed air dryer. This can be particularly performed with a method that uses a fluid bed dryer or flash dryer to dry the expanded or highly refined cellulosic fiber product.
The use of a flash or fluid bed dryer is an advantage over the drying methods suggested by Dinand et al. We have found that through the use of a fluid bed or flash dryer, low temperatures and controlled humidity are not needed to dry the materials of the present invention. In fact, although nearly any drying temperature in the fluid bed or flash dryer can be used, we have dried the product of the present invention using high air temperatures (400 F) and attained a dry product with near equivalent functional properties after rehydration compared to the materials before drying. Additionally, using the process of the present invention, any surface area expanded cellulosic product can be dried and a functional product obtained and is not limited to parenchyma cell wall materials. The use of a fluid bed or flash dryer, the use of relatively high drying air temperatures (400 F +), and the ability to dry non parenchyma cell wall (secondary cell) and obtain a functional product is in great contrast to the relatively low temperatures, e.g.100 C (212 F) and dryer types taught by Dinand et al to dry expanded parenchymal cell wall materials.
The University of Minnesota patent application (Lundberg et al), describes the ability to obtain a functional dried product. However, the only way they were able to obtain a functional dry product was through freeze drying (Gu et al, 2001). -from (Gu, L., R Ruan, P. Chen, W. Wilcke, P. Addis. 2001. Structure Function Relationships of Highly Refined Cellulose. Transactions of the ASAE. VoI 44(6):
1707-1712). Freeze drying is not an economically feasible drying operation for large volumes of expanded cell wall products.
The fiber products of the invention may be rehydrated or partially rehydrated so that the highly refined cellulose product is rehydrated to a level of less than 9Og H2OZg fiber mass, 7Og H2OZg fiber mass, 5Og H20/g fiber mass or rehydrated to a level of less than 30g H2OZg fiber mass or less than 2Og H2OZg fiber mass. This rehydration process adjusts the functionalities of the product within a target range of at least one property selected from the group consisting of water holding capacity, oil holding capacity, and viscosity and may include the use of a high shear mixer to rapidly disperse organic
fiber plant mass materials in a solution. Also the method may include rehydration with soaking of the dry materials in a solution with or without gentle agitation.
The HRC dispersion of the present invention is a highly viscous, semi- translucent gel. HRC embodiments comprise dried powders that are redispersable in water to form gel-like solutions. The functional characteristics of HRC are related to various properties, including water- and oil-retention capacity, average pore size, and surface area. These properties inherently relate to absorption characteristics, but the properties and benefits provided by the processes and products of the invention seem to relate to additional properties created in the practice of the invention. The present invention also includes an aqueous HRC gel having a lignin concentration of about one to twenty percent (1 to 20%). The HRC products of the present invention exhibit a surprisingly high WRC in the range of about 20 to at least about 56 g HϊO/g dry HRC. This high WRC is at least as good as, and in some cases, better than the WRC of prior art products having lower or the same Hgnin concentrations. The HRC products exhibit some good properties for ORC (oil retention capacity).
A general starting point for a process according to the invention is to start with raw material of sufficiently small size to be processed in the initial apparatus (e.g., where soaking or washing is effected), such as a soaker or vat. The by-product may be provided directly as a result of prior processing (e.g., juice removal, sugar removal, betaine removal, or other processing that results in the fiber by-product. The process of the present invention may also begin when raw material is reduced in size (e.g., chopped, shredded, pulverized) into pieces less than or equal to about 10 x 5 cm or 5 cm x 2 cm. Any conventional type of manual or automated size reduction apparatus (such as chopper, shredder, cutter, slicer, etc.) can be used, such as a knife or a larger commercially-sized chopper. The resulting sized raw material is then washed and drained, thus removing dirt and unwanted foreign materials. The washed and chopped raw material is then soaked. The bath is kept at a temperature of about 20 to 1000C. The temperature is maintained within this range in order to soften the material. In one embodiment, about 100 g of chopped raw material is soaked in a 2.5 liter bath within a temperature range of about 20 to 80 degrees Centigrade for 10 to 90 minutes.
The resulting soaked raw material is subjected to another washing and draining. This washing and additional washing and draining tend to be more
meaningful for sugar beets, potatoes, carrots (and to some degree also tomatoes, chicory, apple, pineapple, cranberries, grapes, and the like) than for citrus material. This is because sugar beets, potatoes, carrots, growing on the ground rather than being supported in bushes and trees as are citrus products, tend to pick up more materials from the soil in which they grow. Sugar beets and carrots tend to have more persistent coloring materials (dyes, pigments, minerals, oxalates, etc.) and retained flavor that also are often desired to be removed depending upon their ultimate use. In one embodiment, the soaked raw material is washed with tap water. In one other embodiment, the material is drained. This is optionally followed by bleaching the material with hydrogen peroxide at concentrations of about one (1) to 20% (dry basis) peroxide. The bleaching step is not functionally necessary to effect the citrus and grape fiber conversion to highly refined cellulose. With respect to carrots and sugar beets, some chemical processing may be desirable, although this processing may be significantly less stressful on the fiber than the bleaching used on corn-based HRC products. From our experience, some chemical step is required for sugar beets, and bleaching is one option. Using alkaline pretreatment baths is another option. Acid treatment or another bleaching agent are other options.
The material is optionally bleached at about 20 to 1000C for about five (5) to 200 min. The bleached material is then subjected to washing with water, followed by filtering with a screen. The screen can be any suitable size. In one embodiment, the screen has a mesh size of about 30 to 200 microns.
The filtered material containing solids can then be refined (e.g., in a plate refiner, stone mill, hammer mill, ball mill, or extruder.). In one embodiment, the filtered material entering the refiner (e.g., a plate refiner) contains about four percent (4%) solids. In another embodiment, the refining can take place in the absence of water being added. The plate refiner effectively shreds the particles to create microfibers. The plate refiner, which is also called a disk mill, comprises a main body with two ridged steel plates for grinding materials. One plate, a refining plate, is rotated while a second plate remains stationary. The plates define grooves that aid in grinding. One plate refiner is manufactured by Sprout Waldron of Muncy, PA and is Model 12-ICP. This plate refiner has a 60 horsepower motor that operates at 1775 rpm.
Water may be fed into the refiner to assist in keeping the solids flowing without plugging. Water assists in preventing the refiner's plates from overheating, which causes materials in the refiner to burn. (This is a concern regardless of the type of grinding or shearing device used.). The distance between the plates is adjustable on the refiner. To set refining plate distances, a numbered dial was affixed to the refining plate adjustment handle. The distance between the plates was measured with a micrometer, and the corresponding number on the dial was recorded. Several plate distances were evaluated and the setting number was recorded. A variety of flow consistencies were used in the refiner, which was adjusted by varying solids feed rate. The amount of water flowing through the refiner remained constant. Samples were sent through the refiner multiple times. In one embodiment the materials are passed one or more times through the plate refiner.
The microfϊbers may then be separated with a centrifuge to produce refined materials. The refined materials are then diluted in water until the solids content is about 0.5 to 37%. This material is then dispersed. In one embodiment, dispersing continues until a substantially uniform suspension is obtained, about 2 to 10 minutes. The uniform suspension reduces the likelihood of plugging.
The resulting dispersed refined materials, i.e., microparticles, may then be homogenized in any known high pressure homogenizer operating at a suitable pressure. In one embodiment, pressures greater than about 5,000 psi are used. The resulting highly refined cellulose (HRC) gel may display a lignin content of about 1 to 20% by weight, depending in part upon its original content.
The absence of use of a mild NaOH soaking before the refining step in the present invention prior to high pressure homogenization does not require the use of high temperature and high pressure cooking (high temperature means a temperature above 100 degrees C and high pressure means a pressure above 14 psi absolute). High temperature and high pressure cooking may be used, but to the disadvantage of both economics and output of the product. This novel process further avoids the need for either mild concentrations of NaOH or of highly concentrated NaOH and the associated undesirable environmental impact of discharging waste water containing any amount of NaOH and organic compounds. The process also avoids a need for an extensive recovery system. In one embodiment, the pH of the discharge stream in the present invention is only about 8 to 9 and may even approach 7. The method of the present invention has the further advantage of reducing water usage significantly over
prior art processes, using only about one third to one-half the amount of water as is used in conventional processes to produce to produce HRC gel and amounts even less than that used in the Chen processes
All of the mechanical operations, refining, centrifuging, dispersing, and homogenizing could be viewed as optional, especially in the case of citrus pulp or other tree bearing fruit pulps. Additionally, other shearing operations can be used, such as an extruder, stone mill, ball mill, hammer mill, etc. For citrus pulp, the only processes that are needed to produce the expanded cell structure are to dry (using the novel drying process) and then properly hydrate the raw material prior to the expanding and shearing step of the process of the invention. This simple process could also be used in other raw material sources.
Hydration is a term that means reconstituting the dried fiber back to a hydrated state so that it has functionality similar to the pre-dried material. Hydration can be obtained using various means. For instance, hydration can occur instantly by placing the dry products in a solution followed by shearing the mixture. Examples of shearing devices are a high shear disperser, homogenizer, blender, ball mill, extruder, or stone mill. Another means to hydrate the dry materials is to put the dry product in a solution and mix the materials for a period of time using gentle or minimal agitation. Hydrating dry materials prior to use in a recipe can also be conducted on other insoluble fibrous materials to enhance their functionality.
The initial slurry of fibers/cells from the EPM products is difficult to dry. There is even disclosure in the art (e.g., U.S. Patent 4,413,017 and U.S. Patent 4,232,049) that slurries of such processed products cannot be easily dried without expensive and time consuming processes (such as freeze drying, extended flat bed drying, and the like). Freeze drying is effective, but is not economically and/or commercially desirable. Similarly, tray dryers may be used, but the length of time, labor and energy requirements make the process costly. The slurries of the citrus and/or beet by-products may be dried economically and effectively according to the following practices of the invention. Any type of convective drying method can be used, including a flash dryer, fluid bed dryer, spray dryer, etc. One example of a dryer that can be used is a fluid bed dryer, with dry material being added to the slurry to equilibrate the moisture content in the materials. It has been found that by adding 5:1 to 1:1 dry to wet materials within the fluid bed drier improves the air flow within the drier and the material may be effectively dried. In the absence of the combination
of "dry" and "wet" materials, the slurry will tend to merely allow air to bubble through the mass, without effective drying and without a true fluid bed flow in the drier. The terms wet and dry are, of course, somewhat relative, but can be generally regarded as wet having at least (>40% water/<60%solid content] and dry material having less than 20% water/80% solid content). The amounts are not as critical as the impact that the proportional amounts of materials and their respective water contents have in enabling fluid flow within the fluid bed drier. These ranges are estimates. It is always possible to use "wet" material with lower moisture content, but that would have to have been obtained by an earlier drying or other water removal process. For purpose of economy, and not for enabling manufacture of HRC microfibers according to the present invention from citrus or beet by-product, it is more economical to use higher moisture content fiber mass as the wet material. After the mixture of wet and dry materials have been fluid bed dried (which can be done with air at a more moderate temperature than is needed with flat bed dryers (e.g., room temperature air with low RH may be used, as well as might heated air). A flash drier may also be used alternatively or in combination with a fluid bed drier to effect moisture reduction from the citrus or beet by-product prior to produce a functional dry product. It would be necessary, of course, to control the dwell time in the flash drier to effect the appropriate amount of moisture reduction and prevent burning. These steps may be provided by the primary or source manufacturer, or the product may be provided to an intermediate consumer who will perform this drying step to the specification of the process that is intended at that stage.
One aspect of the drying process is useful for the drying of any expanded cellulose products, especially for the drying of highly refined cellulose fibers and particles that have been extremely difficult or expensive to dry. Those products have been successfully dried primarily only with freeze drying as a commercially viable process. That process is expensive and energy intense. A method according to the present invention for the drying of any expanded cellulose fiber or particle product comprises drying an expanded cellulose product by providing a first mass of expanded cellulose fiber product having a first moisture content as a weight of water per weight of fiber solids; providing a second mass of expanded cellulose fiber product having a second moisture content as a weight of water per weight of fiber solids, the second moisture content being at least 20% less than said first moisture content; combining said first mass of expanded cellulose fiber product and said
second mass of expanded cellulose product to form a combined mass; drying said combined mass in a drying environment to form a dried combined mass. The method may have the dried combined mass dried to a moisture content of less than 20, less than 10, less than 8, less than 5 or less than 3 H20/g fiber mass. The method, by way of non-limiting examples, may use drying environments selected from the group consisting of, flash driers, fluid bed driers and combinations thereof.
The rehydration and shearing (particularly high shearing at levels of at least 10,000 sec"1, preferably at least 15,000 sec"1, more often, greater than 20,000, greater than 30,000, greater than 40,000, and conveniently more than 50,000 sec'1 (which is the actual shearing rate used in some of the examples) of the dry fiber product enables the resultant sheared fiber to retain more moisture and to retain moisture more strongly. It has been noted in the use of materials according to the practice of the invention that when the fiber products of the invention are rehydrated, the water activity level of rehydrated fiber is reduced in the fiber (and the fiber present in a further composition) as compared to free water that would be added to the further composition, such as a food product. The food products that result from cooking with 0.1 to 50% by weight of the HRC fiber product of the invention present has been found to be highly acceptable to sensory (crust character, flavor/aroma, grain/texture, taste, odor, and freshness, especially for mixes, frozen foods, baked products, meat products and most particularly for bakery goods, bakery products, and meat products) tests on the products. Importantly, the products maintain their taste and mouth feel qualities longer because of the higher moisture retention.
As used herein, the terminology "animal protein-containing food product" means any food product that contains animal protein, including, but not limited to, meat. Animal protein-containing food products may include poultry, ham, roast beef, sheep, goat, beef, pork, game, fish, shrimp and scallops, and sausages, including fine paste sausages, such as hot dogs. In one embodiment, the animal protein is preferably derived from animal muscle tissue. In one embodiment, the animal protein-containing food product contains from about 1 to about 90 percent by weight ("% w/w") animal protein, based on the dry weight of such protein and unprocessed meats are included in these values.
An amount of highly refined cellulose that is "effective to enhance moisture retention" means an amount of highly refined cellulose that provides improved moisture retention in an animal protein-containing food product, as measured by, for
example, initial moisture pickup (typically appropriate for evaluating raw foods, such as chicken breasts), cook yield (typically appropriate for evaluating cooked foods, such as ham), cooking loss, and purge measurements (typically appropriate for evaluating packaged foods, such as hot dogs), as compared to a directly analogous animal protein-containing food product without the highly refined cellulose.
In one embodiment, the animal protein-containing food product comprises, based on about 100% w/w of the food product, from about 1% w/w to about 30% w/w muscle protein, from about 30% w/w to about 80% w/w water, up to about 50% w/w fat and from about 0.005% w/w to about 3.0% w/w highly refined cellulose, and more preferably from about 0.1% w/w to about 1.0% w/w highly refined cellulose, and most preferably about 0.2% w/w concentration highly refined cellulose.
Any suitable amount of highly refined cellulose effective to enhance moisture retention may be used. In a preferred embodiment, the highly refined cellulose component is present in an amount sufficient to provide greater than or equal to about 0.005% w/w highly refined cellulose, more preferably from greater than about 0.1% w/w, and still more preferably from about 0.2% w/w to about 1% w/w highly refined cellulose concentration in the animal protein containing food product. Unless otherwise specified, the concentrations of highly refined cellulose given herein are based on the weight of non-hydrated highly refined cellulose. No matter which process is used, an amount of highly refined cellulose effective to provide an animal protein-containing food product having (based on about 100% w/w of the food product) from about 1% w/w to about 30% w/w muscle protein, from about 30% w/w to about 80% w/w water, up to about 50% w/w fat, and from about 0.005% w/w to about 3.0% w/w highly refined cellulose, should be used. The animal protein-containing food product may optionally, contain other ingredients, such as for example, cereal products, milk proteins, sweeteners, soy proteins, vegetable proteins, and salts. Other moisture retention additives, such as for example, polyphosphates, starches, gums, silicates, emulsifiers, or hydrocolloids such as carrageenans may be used in addition to the highly refined cellulose. In one embodiment, one or more ingredients, comprising, for example, ground meat, of the animal protein-containing food product are contacted, associated with, imbibed with, injected with or otherwise combined with the highly refined cellulose, in its dry or hydrated (rehydrated) form. For example, the food product ingredient may be treated by mixing the ingredient with highly refined cellulose in solid
particulate form. The highly refined cellulose treated ingredient may then be incorporated into the food product. Preferred amounts of highly refined cellulose by weight of solid are greater than about 0.05% w/w, more preferably about greater than about 0.1% w/w, and most preferably from about 0.2% w/w to about 1% w/w highly refined cellulose concentration in the animal protein-containing food product. In another embodiment, the animal protein-containing food product is contacted with the alkali silicate by contacting highly refined cellulose, in the form an aqueous highly refined cellulose solution, suspension or dispersion, with the food product. For example, the food product may be contacted with an aqueous composition of the highly refined cellulose by tumbling, dipping, immersion, injection, massage marinating, or by any other suitable means.
In still another embodiment of the present technology, the rehydration and shearing of the dry fiber product enables the resultant sheared fiber to retain more moisture and to retain moisture more strongly. It has been noted in the use of materials according to the practice of the invention that when the fiber products of the invention are rehydrated, the water activity level of rehydrated fiber is reduced in the fiber (and the fiber present in a further composition) as compared to free water that would be added to the further composition, such as a food product. The food products that result from cooking with 0.1 to 50% by weight of the HRC fiber product of the invention present has been found to be highly acceptable to sensory (crust character, flavor/aroma, grain/texture, taste, odor, and freshness, especially for mixes, frozen foods, baked products, meat products and most particularly for bakery goods, bakery products, and meat products) tests on the products. Importantly, the products maintain their taste and mouth feel qualities longer because of the higher moisture retention. The high water absorbency and well dispersed nature of the product also lends itself to be an efficient thickening agent/suspending agent in paints, salad dressings, processed cheeses, sauces, dairy products, meat products, and other food products.
Donuts, breads, pastry and other flour products that are deemed freshest when they are moist, tend to retain the moisture and their sensory characteristics compatible with freshness longer with the inclusion of these fibers. In bakery products, the loaf volume maintains the same with the addition of the product of the present invention. In another embodiment, the HRC products of the present invention possess a WRC and ORC that are at least as good as or even better than prior art products
(including the Chen product) with regard to the water retention characteristics and the strength of that retention. This is true even though the products of the present invention may have a higher lignin concentration than products made using conventional processes and are dried (and the same amount as the Lundberg patents products). It is assumed that the lignin which is present has been substantially inactivated to a sufficient degree so that the undesirable clumping does not subsequently occur. Another reason for these improved properties may be due to a porous network structure that is present in the HRC products of the present invention, but is lost in prior art products due to high concentration soaking in NaOH, and which may be slightly reduced even with the mild NaOH solutions used by the Lundberg Patents.
A number of unexpected properties and benefits have been provided by the highly refined cellulose microfiber product of the present invention derived from parenchymal cell material. These products are sometimes referred to herein as "exclusively parenchymal cell wall structures." This is indicative of the fact that the majority source of the material comes from the cell structures of the plants that are parenchymal cells. As noted earlier, the HRC microfibers of the invention are not produced by mild treatment of the leaves, stems, etc. of the plants (which are not only parenchymal cell wall structures, but have much more substantial cell structures). This does not mean that any source of citrus or beet cells and fibers used in the practice of the present invention must be purified to provide only the parenchymal cells. The relative presence of the more substantive cells from leaves and stems will cause approximately that relative proportion of cell or fiber material to remain as less effective material or even material that is not converted to HRC, but will act more in the nature of fill for the improved HRC microfibers of the present invention. It may be desirable in some circumstances to allow significant portions of the more substantive cells and fibers to remain or even to blend the HRC (citrus or beet parenchyma based) product of the present invention with HRC fibers of the prior art to obtain particularly desired properties intermediate those of the present invention and those of the prior art. In the primary manufacturing process of the invention (that is, the process wherein the cells that have essentially only parenchymal cell walls are converted to HRC microfibers or particles according to the mild treatment process of the present invention), the more substantive cells and fibers may be present in weight proportions of up to fifty percent (50%). It is preferred that lower concentrations of the more
substantive fibers are present so as to better obtain the benefit of the properties of the HRC fibers of the present invention, so that proportions of cells having exclusively parenchymal cell walls in the batch or flow stream entering the refining process stream constitute at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99% or preferable about 100% of the fibrous or cellular material added to the refining flow stream. The final fiber product should also contain approximately like proportions of the HRC product of the present invention with regard to other HRC additives or fiber additives.
Among the unexpected properties and benefits of the HRC materials of the present invention derived from the mild refinement of cells and fiber from citrus and beet by-product are the fact of the HRC fibers, the stability of HRC fibers from parenchymal cells, the high water retention properties, the strength of the water retention properties of the fibers, the ability of the HRC fibers to retain water (moisture) even when heated, the ability of the HRC fibers to retain water (moisture) on storage, and the ability of the HRC fibers to retain moisture in food stuff without promoting degradation, deterioration or spoilage of the food as compared to food stuff with similar concentrations of moisture present in the product that is not bound by HRC fibers. The ability of the fiber materials of the present invention to retard moisture migration is also part of the benefit. This retarded water migration and water activity of water retained or absorbed by the fibers of the invention may be related to the previously discussed binding activity and binding strength of water by the fiber. As the moisture is retained away from other ingredients that are more subject to moisture-based deterioration, the materials of the invention provide significant benefits in this regard. These benefits can be particularly seen in food products (including baked goods such as breads, pastries, bars, loaves, cakes, cookies, pies, fillings, casseroles, protein salads (e.g., tuna salads, chicken salads), cereals, crackers, meats, processed dairy products, processed cheese, entrees and the like) that are stored as finished products either frozen, refrigerated, cooked, or at room temperature in packaging. The HRC fiber of the present invention may be provided as part of a package mix that can be used by the consumer, with the HRC fibers remaining in the final product to provide the benefits of the invention in the product finished (baked or cooked) by the consumer. The HRC fiber materials of the present invention provide other physical property modifying capabilities in the practice of the invention. For example, the fibers can provide thickening properties, assist in suspending or
dispersing other materials within a composition, and the like. These properties are especially present in HRC fibers of the invention provided from sugar beets.
The percentage of fiber in the final product that is desirable to provide identifiable benefits is as low as 0.01% or 0.05 % or 0.1% of the total dry weight of the final product. The HRC fiber product of the invention may be used as from 0.05 to 50% by weight of the dry weight of the product, 0.5 to 40%, 1 to 40%, 1 to 30%, 1 to 25%, 1 to 20%; 1 to 15%, 1 to 10%, and 2 to 20% by weight of the dry weight of the final product.
An unexpected property is for the finished dried product to have a viscosity in a 1% solution of 1000-300,000 centipoise at 0.5 rpms when measured using a Brookfield LVDV++ viscometer (Middleboro, MA). An additional unexpected property is for the end processed product to have similar rheology curves as other common hydrocolloids, such as xanthan gum. The expanded fiber products .of the invention are highly effective and environmentally safe viscosity enhancers. In addition, they are quite useful in edible products, in addition to the functional benefits they add to edible products such as beverages, cheeses, baked goods, liquid and semi- liquid products (stews, soups, etc.).
Suitable aqueous highly refined cellulose compositions are made by blending the components of the solution in water. In one embodiment, the aqueous highly refined cellulose composition consists essentially of highly refined cellulose in water. As used herein, the term "water" generally refers to tap water, that is, water as available onsite without requiring purification that may contain minor amounts of components other than H2O. However, any suitable water may be used.
In a preferred embodiment, the aqueous treatment solution is such that it provides greater than or equal to about 0.005% w/w highly refined cellulose concentration, more preferably about greater than about 0.1% w/w, and most preferably from about 0.2% w/w to about 1% w/w highly refined cellulose concentration in the animal protein-containing food product. Accordingly, a preferred aqueous treatment solution comprises greater than or equal to about 0.05 percent by weight (wt %) of the highly refined cellulose composition more preferably from about 0.1 wt %, still more preferably from about 0.2 wt % to about 15 wt %, and even more preferably from about 0.47 wt % to about 6 wt %, highly refined cellulose, wherein the ranges are calculated on the basis of the weight of the anhydrous highly refined cellulose.
The aqueous highly refined cellulose composition may, optionally, further comprise other components, such as for example, alkali metal silicates, alkali metal salts, such as for example, NaCl, KCl, and surfactants suitable for food use.
In a preferred embodiment, the aqueous composition exhibits a pH of from about 10 to about 14, more preferably from about 11 to about 13.5, even more preferably from about 11.4 to about 13.
Also, in a preferred embodiment, the aqueous highly refined cellulose composition is at a temperature of from about 0 to about 85C, more preferably from 0 to about 7OC, still more preferably from about OC to about 50C, and even more preferably from about OC to about 2OC.
The food product should be contacted with the highly refined cellulose composition for a period of time sufficient to add significant HRC volume with moisture to or even saturate the food product with composition or solution or absorb the composition or solution into the food product. For example, at atmospheric pressure in a dip tank, dwell times from about 5 seconds to about 30 minutes are effective, with a dipping time of about 1 minute or less being preferred. Also, for example, dwell times using tumbling may range from about 30 seconds to several hours. A dwell time of about 1 hour to about 4 hours is preferred at 12 rpm continuously. It is preferred to inject composition into a solid meat product (as opposed to a ground meat product) with multiple injection heads spaced about the meat volume. Food products that have been treated according to the present invention can, immediately after such treatment, be processed according to normal food processing conditions, such as chilling, freezing, or cooking.
Among the unexpected properties and benefits of the HRC materials of the present invention derived from the mild refinement of cells and fiber from citrus and beet by-product are the fact of the HRC fibers, the stability of HRC fibers from parenchymal cells, the high water retention properties, the strength of the water retention properties of the fibers, the ability of the HRC fibers to retain water (moisture) even when heated, the ability of the HRC fibers to retain water (moisture) on storage, and the ability of the HRC fibers to retain moisture in food stuff without promoting degradation, deterioration or spoilage of the food as compared to food stuff with similar concentrations of moisture present in the product that is not bound by HRC fibers. The ability of the fiber materials of the present invention to retard moisture migration is also part of the benefit. This retarded water migration and water
activity of water retained or absorbed by the fibers of the invention may be related to the previously discussed binding activity and binding strength of water by the fiber. As the moisture is retained away from other ingredients that are more subject to moisture-based deterioration, the materials of the invention provide significant benefits in this regard. These benefits can be particularly seen in food products (including baked goods such as breads, pastries, bars, loaves, cakes, cookies, pies, fillings, casseroles, protein salads (e.g., tuna salads, chicken salads), cereals, crackers, meats, processed dairy products, processed cheese, entrees and the like) that are stored as finished products either frozen, refrigerated, cooked, or at room temperature in packaging. The HRC fiber of the present invention may be provided as part of a package mix that can be used by the consumer, with the HRC fibers remaining in the final product to provide the benefits of the invention in the product finished (baked or cooked) by the consumer. The HRC fiber materials of the present invention provide other physical property modifying capabilities in the practice of the invention. For example, the fibers can provide thickening properties, assist in suspending or dispersing other materials within a composition, and the like. These properties are especially present in HRC fibers of the invention provided from sugar beets.
The percentage of fiber in the final product that is desirable to provide identifiable benefits is as low as 0.01% or 0.05 % or 0.1% of the total dry weight of the final product. The HRC fiber product of the invention may be used as from 0.05 to 50% by weight of the dry weight of the product, 0.5 to 40%, 1 to 40%, 1 to 30%, 1 to 25%, 1 to 20%, 1 to 15%, 1 to 10%, and 2 to 20% by weight of the dry weight of the final product.
An unexpected property is for the finished dried product to have a viscosity in a 1% solution of .1000-300,000 centipoise at 0.5 rpms when measured using a Brookfield LVDV++ viscometer (Middleboro, MA). An additional unexpected property is for the end processed product to have similar rheology curves as other common hydrocolloids1, such as xanthan gum. The expanded fiber products of the invention are highly effective and environmentally safe viscosity enhancers. In addition, they are quite useful in edible products, in addition to the functional benefits they add to edible products such as beverages, cheeses, baked goods, liquid and semi- liquid products (stews, soups, etc.).

Non-limiting examples of useful structured triglycerides include caprenin, salatrim and mixtures thereof. Non-limiting examples of useful plant sterols and sterol esters include sitosterol, sitostanol, campesterol and mixtures thereof.
Partially-digestible and non-digestible oils and fats are particularly useful as they impart little or no calories to a food product and can impart a hypocholesterolemic capability to foods that incorporate said fats and oils. Examples of partially-digestible and non-digestible oils and fats that can provide a food with a hypocholesterolemic capability include, by way of example, sucrose polyesters which are sold under the trade name of Olean™ by the Procter & Gamble Company of Cincinnati, Ohio U.S.A.
Preferred partially digestible lipids are structured triglycerides comprising a combination of fluid chain fatty acids (i.e., short-chain saturated or unsaturated fatty acids) with long-chain, saturated fatty acids (chain lengths of C18-C24). An example of a partially digestible lipid is caprenin (Procter & Gamble Company, Cincinnati, Ohio, U.S.A.), which is a structured triglyceride comprised of octanoic acid (C8:0), decanoic acid (C 10:0), and behenic acid (C22:0). Other examples are the reduced calorie triglycerides described in U.S. Patent No. 5,419,925, which are triglycerides comprised of short chain-length, saturated fatty acids (C6:0-C10:0) and long chain- length, saturated fatty acids (C18:0-C24:0). Another example of partially digestible lipids are the salatrim family of low calorie fats developed by the Nabisco Foods Group (East Hanover, New Jersey). The salatrim low-calorie fats are triglycerides comprised of short chain fatty acid residues (C2:0-C4:0) and long chain, saturated fatty acids (C16:0-C22:0. Salatrim is available under the brand name, Benefat™ from Cultor Food Science (Ardsley, N. Y.). Benefat™ is a specific component of the
salatrim family, comprising acetic (C2:0), proprionic (C3:0), butyric (C4:0), and stearic (Cl 8:0) acids.
Useful surface active lipids are amphiphilic molecules that may be purposefully added to food compositions for their functional performance or to enhance processability. Although these ingredients are adjunct ingredients, they will be detected as digestible fat by Applicants' analytical methods. Examples of surface active lipids are emulsifying agents, which are surface active lipids that stabilize oil- in-water or water-in-oil emulsions by orienting at the oil/water interface and reducing the interfacial tension; and foaming agents, which are surfactants that orient at the gas-water interface to stabilize foams. Surface active lipids may also be added as an inherent component of a food ingredient, such as the phospholipids found in soybean oil and egg yolks (e.g., lecithin). Tn addition, surface active lipids may be formed in the food as a result of the processing. For example, free fatty acids are formed in frying oils as a result of hydrolysis of the triglycerides and these fatty acids will be transferred to the fried food along with the oil that is transferred to the food.
Useful surface-active agents include, but are not limited to, free fatty acids, monoglycerides, diglycerides, phospholipids, sucrose esters, sorbitan esters, polyoxyethylene sorbitan esters, diacetyl tartaric acid esters, polyglycerol esters and mixtures thereof. As used herein, the term "carbohydrate" refers to the total amount of sugar alcohols, monosaccharides, disaccharides, oligosaccharides, digestible, partially digestible and non-digestible polysaccharides; and lignin or lignin like materials that are present in the embodiments of the present invention. Carbohydrates that can be incorporated into the present invention may include, but are not limited to, monosaccharides, disaccharides, oligosaccharides, polysaccharides, sugar alcohols and mixtures thereof.

Various recipes for snacks, chips, matzos and other unleavened food products are described in US Patent Nos. 6,479,090, which are herein incorporated by reference for their recipes, as are all references cited herein, including the applications ans Patents in the priority claim.
Cohesive, machinable doughs which can be sheeted, stretched, and cut into pieces may be produced at room temperature when the doughs possess a high content of wheat or other gluten-containing flour. The baking of conventional wheat-based doughs into crackers provides a lamellar structure with generally uniform small cells and a tender, mealy, leavened texture. Upon mastication, the conventional crackers generally disperse more rapidly than does a chip. They do not provide a crunchy texture and a sensation of breaking into pieces with low molar compaction before dispersion as does a chip. Additionally, crackers are generally dockered to prevent pillowing and to provide a generally flat bottom surface and a blistered top surface. Oyster or soup crackers and snack crackers which have a pillowed appearance may be produced from wheat-based doughs by the elimination of dockering holes. However, these products still possess a leavened, tender, mealy texture and a cracker appearance, rather than a crisp, crunchy chip-like texture and chip-like appearance. Filled baked crackers or snacks obtained by needle injection of fillings into hollow expanded snacks made from wheat flour are disclosed in U.S. Patent No. 4,209,536 to Dogliotti, U.S. Patent No. 4,613,508 to Shishido, U.S. Patent No. 4,752,493 to Moriki, and U.S. Patent No. 5,000,968 to Szwerc et al. Production of a chip-like snack having surface bubbles and surrounding crisp, thin regions is not disclosed in these patents. The doughs are formulated and processed to retain a puffed or pillowed shape after piercing of the baked/hollow piece.
A cellular structure is obtained by the use of egg white in the shell of the pastry product of U.S. Patent No. 4,209,536 to Dogliotti.
In the process of U.S. Patent No. 4,613,508 to Shishido, hard dough biscuits are prepared by baking a dough having 10-30 parts by weight of sugar, 10-25 parts by
weight of edible fat or oil, 1.5-4.0% leavening agent, and 20-35 parts by weight of water per 100 parts by weight of cereal flour to obtain a degree of leavening of at least 280%.
The baked hollow expanded snacks in the form of a figure such as an animal or vehicle of U.S. Patent No. 4,752,493 to Moriki are produced from a farinaceous raw mixture. The raw mixture is prepared by mixing from 60-95 parts by weight of at least one low swelling-capacity farinaceous material and 40-5 parts by weight of at least one high swelling-capacity farinaceous material. The low swelling-capacity material may be a non-glutinous cereal such as wheat, rye, maize, non-glutinous rice, sago, sorghum, triticale, millet and beans, or starches separated from these sources. The high swelling-capacity material may be potato, taro, tapioca, arrowroot, sweet potato, glutinous rice, waxy corn, or starches derived from these sources having their cell walls broken. The farinaceous raw mixture is partly gelatinized prior to rolling into a smooth sheet by the addition of hot water or by the action of steam, so as to raise the temperature of the farinaceous raw mixture to 65°C to 900C. According to Moriki, upon baking, the starch in the surface of the dough pieces is gelatinized, thereby forming a skin having good gas-holding capacity and excellent stretchability. Water and volatile materials in the dough pieces push the skin outward upon heating, so that the dough pieces expand and are internally split into two layers or shells, forming a hollow space therebetween.
The filled crackers of U.S. Patent No. 5,000,968 to Szwerc et al. are produced from a dough containing proteolytic enzymes. The enzymes hydrolyze proteins of the flour, which relaxes the dough and thereby permits a hollow center to be formed, rather than a cellular center, as the cracker expands under the influence of the leavening agent during baking. This, it is disclosed, strengthens the shell of the cracker and permits the cracker to be filled by means of an injection needle piercing the surface of the cracker.
A standard recipe for a baked good known as a cracker includes at least the following as a non-limiting example: 3Og Active dry yeast
3Og Sugar
0.80 L Warm water; (105 to 115)
2.5 L (25Og) All-purpose flour; (3 to 3
-1/2) Or whole wheat flour * 1Og Salt
0.12 L Vegetable oil
1Og Crushed caraway (or other seed, e.g., fennel or cumin seeds)
Generally the recipe calls for 70-90% by weight flour, 2-8% yeast, 0-10% sugar, 0- 8% salt, 0.005 to 2% consumable oil, 5-30% water and 0-5% flavoring or seed additive.
* (or three parts all-purpose to one part rye, buckwheat, corn or oat flour).
In a small bowl, dissolve the yeast and sugar in the water. In a medium bowl, blend the flour and salt. Make a well in the center of the dry ingredients and add the vegetable oil and caraway seeds. Add the yeast mixture and stir the dry ingredients into the wet ingredients. Remove the dough to a lightly floured board and kneed a few times until smooth. Transfer to an oiled bowl, turn the dough to grease it: let rise until doubled in bulk, about 1 hour.
Preheat oven to 350F, punch the dough down and cut into 20 pieces. Roll each piece into a ball and press into a disk. Roll one disk of dough out as thin as possible, by hand or with a pasta machine, into a round or oblong. Place 2-4 crackers
(however many will fit) on a lightly oiled baking sheet and prick with a fork at 2 inch intervals. Bake until lightly browned around the edges, about 15 minutes. Remove to a rack and allow to cool and finish drying out. store in an airtight tin. Repeat with the remaining balls of dough, (makes 20 very large crackers).
The seed may be placed in the dough rather than on it, sprinkling them on top before baking. Paint the dough with egg yoke mixed with water for a glaze. Put coarse salt and cracked pepper on top.
A typical hard pretzel recipe may be described as:
1 packet active dry bread yeast (10-50 g) warm water (0.2-0.8 L)
~2 T soft butter or margarine (20-50 g) ~2 3/4 cups bread flour (200-60Og)
1/2 t salt (0-3Og)
1 T sugar (0-25g)
5 t baking soda (10-4Og) or
Mix T (5-4Og) to 1/2 cup bicarbonate of soda warm water for glazing Coarse salt for coating mixture if desired.
The pretzels are allowed to rise at room temperature, then rolled and shaped, and baked in a preheated, moist oven.
The production of chip-like, starch-based snacks having a crispy texture and surface blisters from starch-based compositions which have little or no gluten, such as potato flour or corn flour, is disclosed in U.S. Patent Nos. 4,873,093 and 4,834,996 to Fazzolare et al. and U.S. Patent Nos. 5,429,834 and 5,500,240 to Addesso et al. Starch-based compositions which have little or no gluten, when mixed with water, do not form a dough that is cohesive at room Temperature and continuously machinable or sheetable. Machinability of doughs made from ingredients having little or no gluten may be improved by forming a dough under elevated temperature conditions, such as by steaming the ingredients, as disclosed in U.S. Patent Nos. 4,873,093 and 4,834,996 to Fazzolare et al.
It should also be appreciated that the compositions of the solutions and methods used in the process of the invention may be varied according to the desired characteristics of the food product. The following non- limiting examples will further illustrate the preparation and performance of the invention. However, it is to be understood that these examples are given by way of illustration only and are not a limitation of the invention. EXAMPLES Example I
Turkey breast meat was ground using a 3/8 inch plate. The pH of the raw meat was then measured. Next, aqueous treatment solutions were prepared of one of the following components: anhydrous sodium metasilicate (SMS) having a ratio of 1 (e.g., wherein m is 1 and M is sodium), sodium hydroxide (NaOH), or Sodium Carbonate (Na.sub.2CO.sub.3). The treatment solutions were prepared using salt, water and one of the above listed components to yield concentrations of 0.2, 0.4, 0.6, and 0.8% w/w of the component in the treated meat. Control 1 was prepared using a treatment solution of water and salt, only, i.e. no additional active ingredients such as phosphate, hydroxide, carbonate, or alkali silicates. Controls 2 and 3 were prepared using dextrose as a filler, water, and salt. However, no additional active ingredients were used in Controls 2 or 3 either. The concentration of dextrose was at 0.3% w/w and 0.7% w/w respectively. Table IA below shows the recipe for the various treatment solutions.
EAXMPLES
EXAMPLE 1
Dried beet pulp shreds were obtained from a local feed store. The beet pulp was then ground to a powder using a disk mill or refiner. One particularly useful plate refiner is manufactured by Sprout Waldron of Muncy, PA and is Model 12-ICP. This plate refiner has a 60 horsepower motor that operates at 1775 rpm. After the dry materials were ground, they were soaked in hot water at 1000C for 5 minutes at 5% solids, where the materials started to absorb moisture. The soaked materials were then washed with water in a screen cart to remove any unwanted particulate or soluble materials. After soaking, the materials were diluted to 3% solids and bleached in a 150 gallon (555 liter) tank with agitation. The bleaching conditions were 15% hydrogen peroxide (based on dry matter weight), a pH of 11.5, and a temperature of 800C for one hour. After bleaching, the material was then washed in a screen cart. After bleaching, the materials were then refined again at 3% solids using the same refiner in the first step, which was followed by further reducing particle sizes in an IKA Dispax Reactor, Model DR 3-6A (Wilmington, NC). The dispersed materials were then homogenized three times at 8000 psi (approximately 5x105 sec"1 shear rate) using a APV Gaulin high pressure homogenizer, Model MC(P)-45 (Wilmington, MA). The homogenized materials were then dried at 1200F in a Harvest Saver Dehydrator made by Commercial Dehydrator Systems (Eugene, OR). The dried materials were then ground in a Fitzmill, Model D6 (Elmhurst, IL), with a 0.050 inch (0.12 cm) round 22 gauge 316 mesh stainless steel screen. After grinding, the ground materials were then rehydrated at 1% solids using a standard kitchen household blender on high speed for three minutes. Viscosity was then measured using a Brookfield LVD V++ viscometer (Middleboro, MA) with cylindrical spindles. Keltrol xanthan and propylene glycol alginate (PGA) were obtained from CP Kelco. 1% solutions were made by mixing the materials in a blender for 3 minutes. Rheology was determined using the same Brookfield viscometer. The results are shown in Figure 1. This data shows that the fibers of the invention are capable of providing a viscosity of at least 23,000 at a concentration of 1% fibers derived from sugar beets at 1 rpm at 200C. It is within the skill of the artisan using the teachings of this invention to provide viscosities of greater than 24,000 and greater than 25,000 at these concentrations and conditions to produce the parenchymal cell based highly refined cellulose fibers of the invention. This is evidence by Figure 1.
Figure 1 describes a Comparison of rheology curves for Fiberstar's processed beet pulp versus xanthan and PGA (propylene glycol alginate).

Fluid bed drying
Fluid bed drying trials were performed using a Carrier Vibrating Equipment (Louisville, KY) a one square (foot vibrating fluid bed dryer. Dry products were attained having functionality that was near identical to the wet feed materials. The drying tests were conducted using 100 - 1400F (38-600C) outlet air temperatures, 4000F (2050C) air inlet temperatures, and residence times in the dryer were around 5- 25 minutes. All materials that underwent drying were dried to less than 15% moisture. All viscosities were measured at 1% using a Brookfield LVDV++ viscometer (Middleboro, MA) with cylindrical spindles. Prior to drying, the wet materials need to be back mixed (that is wetter materials are added to the drier materials to facilitate drying of the wetter materials) with the dry materials (backmix ratio was 2 parts dry to 1 part wet) and a total of 6 lbs (2.6 kg) of wet feed was put in the batch style dryer. The results from the testing are shown below:

EXAMPLE 10: Flash drying
Pilot scale Flash drying trials were performed using a Carrier Vibrating Equipment (Louisville, KY) Tornesh dryer. Prior to drying, the wet materials (dispersed orange pulp, as from Example 2) were to be back mixed with the dry materials, again orange pulp from Example 2 (backmix ratio was 2 parts dry to 1 part wet) and a total of 30 lbs (13 kg) of 50% moisture wet feed was put in the dryer- Dry products were attained having functionality that was similar to the wet feed materials. The drying tests were conducted using 2000F (940C) outlet air temperatures and residence times in the dryer were around 1-3 minutes. The dried materials were rehydrated using a blender on high speed for 3 minutes and all viscosities were measured at 1% using a Brookfield LVD V++ viscometer (Middleboro, MA) with cylindrical spindles. The results from the testing are shown below:

PRODUCT USE EXAMPLES OF HIGHLY REFINED CELLULOSE MATERIALS. EXAMPLE 11:
A reduced fat shortening was made by adding Citri-Fi™ 200 FG citrus fiber coprocessed with guar gum from Fiberstar, Inc., water, and vegetable shortening. The water level used was both three and six times the weight of Citri-Fi™ and one half of the shortening was replaced with citrus fiber and water combination. Test 1 contained 100% vegetable shortening. Test 2 contained shortening at 50% and the balance being Citri-Fi™ 200 FG (citrus fiber, guar gum) and water at 6 times the weight of fiber. Test 3 contained shortening at 50% and the balance being Citri-Fi™ 200 FG (citrus fiber, guar gum) and water at 3 times the weight of fiber. All tests were conducted at 75°F with five replicates. The spreadability of the spreads were evaluated using a texture analyzer available from Texture Technologies with a spreadibility rig (TA-425 TTC) to measure the cohesive and adhesive forces of the spreads. The test results are shown in Table 1.

Table 1: Cohesive and adhesive forces as measured by a texture analyzer of a 100% vegetable shortening compared to 50% shortening and balance being Citri-Fi™ 200 FG (citrus fiber, guar gum) and water at 6 times the fiber weight (Test 2) and 3 times the fiber weight (Test 3).
The spreadability results from Table 1 show that a 50% shortening spread can be made with very similar spreadability to a 100% shortening product. And the adhesive and cohesive forces can be adjusted depending on the amount of water used along with the citrus fiber. In this example, if water is used at three times the weight of the citrus fiber, guar gum, then the spread had more adhesive and cohesive forces and was more firm. Whereas if water is used at six times the weight of the citrus fiber, guar gum, then the spread had less cohesive and adhesive forces and was slightly less firm.
EXAMPLE 12: Another test was conducted by adding Citri-Fi™ 200 FG (citrus fiber, guar gum), water, to a low trans roll-in, commonly used in the production of Danish, available from Bunge. Once again various water levels were used to evaluate the differences of water levels but another variable of the amount of roll-in replaced was also evaluated. The amount of roll-in replaced was 33% and 50%. Once again the cohesive and adhesive forces were measured using a texture analyzer. Test 4 contained the low trans roll in at 100%. Test 5 contained the low trans roll in at 66% and the remaining being fiber and water at six times its weight. Test 6 contained the low trans roll at 50% and the remaining being fiber and water at 3 times the weight of fiber. Test 7 contained low trans roll in 50% and the remaining being fiber and water at 6 times the weight of fiber. The test results are shown in Table 2.

Table 2: Cohesive and adhesive forces as measured by a texture analyzer of control low trans roll in and reduced fat low trans roll-in spread. Test 4 contained the low trans roll in at 100%. Test 5 contained the low trans roll in at 66% and the remaining being fiber and water at six times its weight. Test 6 contained the low trans roll at 50% and the remaining being fiber and water at 3 times the weight of fiber. Test 7 contained low trans roll in 50% and the remaining being fiber and water at 6 times the weight of fiber.
The results from this testing suggests that with the low trans roll in product, using water at six times the weight of Citri-Fi™ 200 FG (citrus fiber, guar gum) was effective at making a product with similar cohesive and adhesive forces when doing a 33% roll-in replacement, however, at the higher replacement level of 50%, the roll-in was considerably more firm when water was used at either 6 or 3 times the weight of fiber. These results would indicate that to attain a similar spreadibility for this product, a higher water level could be used.
EXAMPLE 13:
Another round of tests was conducted using a margarine roll in commonly used in the production of Danish. This time a straight water level of six times the weight of Citri- Fi™ 200 FG (citrus fiber, guar gum) was used and two levels of roll-in replacement were evaluated, namely, 50% and 33% replacement. The cohesive and adhesive forces were measured using the same texture analyzer and rigging as in examples one and two. Test 8 contained 100% margarine roll-in. Test 9 contained margarine roll-in at 66% and the balance being Citri-Fi™ 200 FG (citrus fiber, guar gum) and water at 6 times the weight of fiber. Test 10 contained margarine roll-in at 50% and the balance being Citri-Fi™ 200 FG (citrus fiber, guar gum) and water at 6 times the weight of fiber. The test results are shown in Table 3.

Table 3: Cohesive and adhesive forces as measured by a texture analyzer of control margarine roll in and reduced fat margarine roll-in spread. Test 8 contained 100% margarine roll-in. Test 9 contained margarine roll-in at 66% and the balance being Citri-Fi™ 200 FG (citrus fiber, guar gum) and water at 6 times the weight of fiber. Test 10 contained margarine roll-in at 50% and the balance being Citri-Fi™ 200 FG (citrus fiber, guar gum) and water at 6 times the weight of fiber.
The test results shown in Table 3 suggest that with this margarine roll-in, a water level of 6 times the weight of fiber may be higher than what is needed to make a reduced fat roll-in with equivalent spreadability compared the full fat control.
EXAMPLE 14:
In Example 11 and in Example 12 we showed that the by adding water at three times the weight of the Citri-Fi™ 200 FG (citrus fiber, guar gum) can make the reduced fat spread more thick compared to the control spread. However, an alternative way to make a more cohesive and adhesive texture is to start with a fat that has a harder texture and to add the 6 times water and fiber to this starting mixture. In this example, a Swede Gold shortening was used along with Citri-Fi™ 200 FG (citrus fiber, guar gum) and water at 6 times the fiber weight. The texture of this combination was compared to the control roll-in as shown in Test 8. The spreadability of the spreads was evaluated using a texture analyzer available from Texture Technologies with a spreadibility rig (TA-425 TTC) to measure the cohesive and adhesive forces of the spreads.

Table 4: Cohesive and adhesive forces as measured by a texture analyzer of control margarine roll in and reduced fat margarine roll-in spread. Test 8 contained 100% margarine roll-in. Test 11 contained a hard fat roll-in that was reduced by 50% with Citri-Fi™ 200 FG (citrus fiber, guar gum) and water at 6 times the fiber weight.
EXAMPLE 15: A control Danish made with 100% margarine roll-in was compared to a Danish made with a reduced fat roll-in that was prepared and compared to a 66% roll-in and balance being Citri-Fi™ 200 FG (citrus fiber and guar gum). The water level used was six times the weight of the fiber. Roll in is typically used in a Danish to produce the flaky and layered texture that is desired for a Danish or croissant. Thus, the test with the reduced fat roll in to see if the layered texture and flakyiness could be maintained when the roll-in had a percentage replaced with Citri-Fi™ 200 FG (citrus
fiber and guar gum) and water. The following formula was used for the control and reduced fat Danish.

Table S: Formula used in the production of a control and reduced fat roll-in Danish.
After baking, the eating qualities in terms of taste, texture, flakiness, of both the control and reduced fat Danish were noted to be near identical to each other, which suggests that the Citri-Fi™ 200 FG (citrus fiber and guar gum) and additional water in the reduced fat roll-in can maintain the integrity of the full fat roll-in to provide a layered and flaky texture.
EXAMPLE 16: REDUCEDFAT CAKE
Citri-Fi™ 100 citrus fiber from Fiberstar, Inc. was used in testing a 50% reduced fat shortening cake formula. The amount of Citri-Fi™ 100 citrus fiber used was 0.125 times the weight of shortening removed from the formula and the amount of water was 7 times the weight of Citri-Fi™ 100 citrus fiber. The nutritional analysis for the control and test cake formula was generated using Genesis software from Esha Research (Salem, OR). The cake was made according to the formula shown in Table 1:

Because shortening has a softening effect in bakery products and allows them to stay fresher longer, these results show that Citri-Fi™ citrus fiber can be used to replace fat, shortening, and oil and maintain a product with similar eating qualities to the control.

EXAMPLE 19: REDUCED FAT MUFFINS
In addition to making a reduced fat shortening, roll-in, or spread, expanded cell wall materials can also be used to reduced the fat in an oil. The resultant reduced fat oil has a similar consistency as a standard oil and when this is added into a formula, the resultant product has very similar eating qualities compared to the full fat oil. In this experiment, Citri-Fi™ 100 citrus fiber was used to reduce oil in a muffin formula. A Multi-Foods muffin mix (# 44812) was used in this testing and the control formula was followed according to the instructions on the bag. The formula used for the muffins is shown below:

Although all crackers have similar eating qualities and taste, it was apparent that the level of Citri-Fi™ fiber additive could be used to adjust the strength of the crackers up or down. For example, in Test 1 with 1.5% Citri-Fi™ 100 FG fiber additive, the strength was noticeably increased compared to Test 2 that had a reduced 0.75% of the flour weight of Citri-Fi™ fiber additive 100 FG, while both were significantly stronger compared to the control.

EXAMPLE 23 (with Comparison Example)
Cracker samples were sent to Merlin for evaluation. Samples were received on 4-18- 06 and evaluated on 4-20-06. The samples were identified as:
• Saltines crackers Control
• Saltines crackers 0.5% Citri-Fi IOOFG
• Saltines crackers 1% Citri-Fi IOOFG
3-Point Bend Protocol
The 3-Point Bend test is performed using an adjustable bridge platform (TA- 92) and a rounded end knife blade probe (TA-42). The bridge platform has two rails and for this evaluation the rails were spaced 1-inch apart. The cracker sample is supported by the two rails at each edge. The probe contacts the sample along a center line and continues to descend through the cracker measuring the force it takes to break it. The pre-test speed was 3.0 mm/second. The rounded end knife blade traveled at that speed until the Texture Analyzer's surface detection feature detected 10 grams of force (trigger) and which point it traveled 15.0 mm through the cracker at a speed of 1.0 mm/second. The probe withdrew at a speed of 10.0 mm/second. Fourteen to fifteen crackers were tested for each variable.
Results
The crackers containing 1% Citri-Fi 100 FG™ additive took significantly more force to break. The distances to peak were not significantly different between variables. This means it is taking a similar distance to affect breakage. One other trend that was noticed during the testing was the number of stress fractures before the final break. Control had the highest number. The presence of Ci tri Fi 100™ additive in the cracker appeared to reduce the number of stress fractures. Sensory evaluation did not pick up any flavor differences between the samples. All samples were crisp. The 1.0% Citri-Fi IOOFG™ additive sample was slightly more dense and tough than control.
The meat was placed in a mixer, and then half of the treatment solution was added and mixed for about 30 seconds at speed 1. The bowl was scraped, tKen the remaining treatment solution was added while mixing for four (4) minutes at speed 1. About one minute prior to the end of the mixing process, the mixer was stopped and the bowl was scraped. The pH of the treated ground meat was measured. The meat paste was then placed in aluminum cups or loaf pans. The . weight was standardized at 400 grams per cup. The cups were each sealed with a plastic foil and the meat was cooked in a baking oven, until the core temperature reached 72.2C (162F). The total cooking time was about 1.5 hours at HOC (230F). The cooked product was left to cool for about 1 hour at room temperature. After cooling, the meat was dried in absorbent paper then weighed.
Examples for using expanded fiber products to replace binders in meats
EXAMPLE 24: Testing in Injected Meats to replace Phosphates
The following steps were used to make an injected meat product where all or a portion of the sodium tripolyphosphate was reduced using an expanded fiber product.
1) Marinades as outlined in the formulations shown in Table 1 were made by putting the phosphate (for the control) in solution first using warm temperature tap water. Then ice was put in the water to cool the brine down to 32 F. Then the remaining ingredients were added and mixed.
2) Boneless chicken breast that previously had been not been injected was weighed before injecting, which was recorded as the green weight.
3) Brine was injected into the chicken at 15%. The meat weight was measured the after injecting.
4) The injected meat was put into a storage bag and cooled for 18 hours. The weight of the drained meat/brine was measured to calculate the purge weight.
5) The meat was put in a plastic bag and water cooked to 160 F internal temperature. The post cooked meat weight was measured. -Table 1 : Example formulations for a control that contained sodium tripolyphosphate versus an expanded fiber test.
The results for the experiment as described above are shown in Table 2. The results show that with 3% Citri-Fi® IOOFG citrus fiber in the brine there was an improvement in the purge compared to the control. The purge for the control with
sodium tripolyphosphate is 3.5% while with 3% Citri-Fi IOOFG citrus fiber the purge was down to 2.7%. This means that Citri-Fi™ IOOFG citrus fiber was able to control purge and reduce leakage in the meat. Yield values are also shown in Table 2.
Table 2: Purge and yield value results for an injected meat that contained sodium tripolyphosphate versus a Citri-Fi™ fiber test that did not. Formulations for this experiment are shown in Table 1.

In these experiments meats were injected following a control formula and procedure very similar to the one shown in Example 1 except no sodium tripolyphosphate was used and this was compared to various other levels of different types expanded fibers. These results from these experiments are shown in Table 3. Table 3: Results from using various levels and types of Citri-Fi citrus based fibers compared to a control that contained no sodium tripolyphosphate.

The results in Table 3 show that the best percent purge results are obtained with 1% Citri-Fi 200FG citrus fiber and guar gum where the percent purge was 1.7%. This compares to the control which contained no water binder / sodium tripolyphosphate and the percent purge for this test was 6.3%, which is over 3 times more purge or leakage from the meat compared the 1% Citri-Fi 200FG citrus fiber and guar gum test. The next best test was the 1% Citri-Fi 300FG citrus fiber and xanthan gum where the purge was 1.9% and yield was 87.1%. There did not appear to be a large benefit of using higher levels of the 200FG or 300FG in this series of testing.
Example 26: More phosphate replacement testing
In these experiments meats were injected following a control formula and procedure very similar to the one shown in Example 1 except mixtures of sodium tripolyphosphate and expanded fibers were used. These results from these experiments are shown in Table 4. Table 4: Results from using various levels and types of Citri-Fi citrus based fibers and sodium tripolyphosphate.

The results in Table 4 show the best values in terms of green yields were obtained with a combination of phosphate and Citri-Fi™ citrus fiber while the best purge results still are still with the Citri-Fi citrus fibers alone.
EXAMPLE 27: Non fat dry milk replacement testing
Comparison tests were done to compare meats made another moisture binder, non fat dry milk (NFDM), versus an expanded fiber product added dry and in solution in a Dutch Loaf meat product. 4% NFDM was added dry, as per normal industry method, in a 28% fat meat block and emulsified to make the control. For one test 1% Citri- Fi® 100M40 citrus fiber was added dry and in solution and emulsified. For a second test, 2% Citri-Fi™ citrus fiber plus an additional 8% water was added in solution and emulsified. Emulsions were added to ground beef and pork and mixed, hand stuffed in pans and oven cooked on a step cycle. After cooking to 152 F., no purge was found in any of the four products and cook shrinks were not considered this to be a significant difference. AU samples looked, tasted and sliced alike. NOTE-the 1% Citri-Fi 100M40 citrus fiber added dry expanded approximately 1/2 inch during cooking, but returned to normal after chilling. The 2% Citri-Fi™ citrus fiber formula could have held more water and the expanded fiber product was found to be a good replacement for NFDM in these type of products.
EXAMPLE 28: Phosphate and carageenan replacement testing
The purpose of this was test to demonstrate the ability of expanded fiber products to replace phosphates in a cooked poultry slicing loaf. A control was made out of a boneless chicken breast that was ground through a 1/8 inch plate and mixed for 8 minutes along with 1.7% salt, 1.7% dextrose, 0.5% sodium phosphates, sodium nitrite and 24% chilled water. Sodium erythorbate and 1.0% carrageen was added dry to the mix and mixed for 4 minutes. The mix was cured at 36 F. for 30 hours, stuffed in a mold lined with a zip lock bag and water cooked at 160 F. to an internal temperature of 160 F. and chilled in an ice/water bath. The resultant control product was firm, had no evidence of carrageen, sliced well and tasted good.
For the first test (Test 1), the same procedure as outlined above was followed except there no phosphates or carrageenan and replaced with an expanded fiber product. 0.5% Citri-Fi 100M40 citrus fiber was added dry after the initial mixing for 8 minutes and mixed for an additional 4 minutes. Cured, cooked and chilled as above. The Test 1 result had 3.3% purge after cooking and chilling. The product looked good (except for small air holes), had no evidence of fiber, sliced well, was firm and tasted good.
For the second test (Test T), 1 pound of meat was formulated in a small loaf using Citri-Fi 100M40 citrus fiber at 0.5% (total weight) in solution and adding during the first mixing stage. The results from Test 1 showed no purge, sliced well, no evidence of fiber, and tasted good.
