Invention Title: LOW CARBOHYDRATE COMPOSITIONS The following statement is a full description of this invention, including the best method of performing it known to me/us: i LOW CARBOHYDRATE COMPOSITIONS FIELD OF THE INVENTION [0001]The invention relates to compositions for use in food products made from low digestion, low absorption carbohydrates and methods for producing the same. The composition described herein may be used as a binder and/or coating for food products and advantageously reduces or eliminates cold flow while maintaining pleasing organoleptic properties.
BACKGROUND
[0002]Conventional food products generally utilize of a mixture of sucrose and glucose as a sweetening agent. Sucrose, for example, is commonly used to provide both the sweetness and body in food products, e.g. confectionery products; furthermore, its properties also govern the texturarattributes of such products. Recently, however, many consumers have become interested in low carbohydrate diets and wish to avoid food products high in full calorie, fully digestible carbohydrates sucrose and/or glucose).
[0003]Although a wide variety of alternative sweeteners are commercially available, it is generally considered that sucrose is the optimum sweetener with regard to taste profile and technological properties. Sub-optimal physical properties such as lowered glass transition temperature which may be associated with the use of sugar substitutes, such as, for example, sugar alcohols, is correlated with cold flow. For the purposes of discussion herein, cold flow refers to the undesirable property of compositions to loose structural integrity, i.e. to "melt" or "deform" relative to their original shape. As is known in the art, cold flow is directly related to the glass transition temperature. Additionally, cold flow may be exacerbated by a material's tendency to absorb water, i.e. hygroscopicity.
[0004]The accepted theory in the scientific community relative to glass transition temperature is that as the molecular weight (MW) of a pure substance increases, cold flow decreases (see "Investigation in the Addition of Polydextrose or HSH to isomalt- Based Hard Candies" of Raudonus et al; "SPI Polyols'": Application Bulletin" of SPI I O Polyols, Inc., incorporated herein by reference). However, despite the accepted theory C that increased molecular weight positively affects cold flow in pure substances; Raudonus Set al. found in their study of mixed sugar alcohols, that the Tg of anhydrous combinations of isomalt (MW 344) and polydextrose (MW approx. 2200) drops below the Tg of pure isomalt (63"C) at a 40:60 ratio. Raudonus et al. further concluded that fairly high amounts of polydextrose and high molecular types of hydrogenated starch 00 hydrolysate (HSH) in isomalt blends are needed to increase Tg effectively, compared to pure isomalt. Additionally, Raudonus found that the addition of low molecular HSH S causes a reduction of Tg of about 10°C to 15C compared to pure isomalt. Food Research Inteational 33 (2000) 41-51, found that anhydrous blends of isomalt and maltitol syrup solids, especially in ratios of 50:50 to 90:10 (isomalt to maltitol syrup solid basis), have a lower glass transitional temperatures than isomalt or maltitol cooked alone.
[0005]Therefore, it would be advantageous to develop a sweetener mixture that can be used as a binder or coating, that includes carbohydrates having lower calorie <4 cal/g), lower digestion and absorption, while preserving desired characteristics such as high glass transition temperature and reduced cold flow.
Advantages of the present invention will be apparent to those skilled in the art upon consideration of the present disclosure.

BRIEF DESCRIPTION OF THE DRAWING [0014]FIG. 1 provides a process diagram for the production of low-carbohydrate peanut bars made for low digestion, low absorption carbohydrates 4 cal/g).
DETAILED DESCRIPTION [0015]A low calorie cal/g), low digestion carbohydrate composition derived from mixtures of sugar alcohols is provided. The blend of components in the coating composition is effective for maintaining a sufficiently high glass transition temperature useful for avoiding cold flow, maintaining a crispy, crunchy texture over the coatings shelf-life with reduced stickiness, and for providing a sweet melt-in-your-mouth flavor.
[0016]As used herein, low carbohydrate content refers to a food composition or coating havingless than about 50 weight percent of full calorie, fully digestible carbohydrates, and preferably less than about 12 percent fully digestible carbohydrates. Low carbohydrate content may be further defined as a food composition or coating having less than about grams of full calorie 4 cal/g), fully digestible carbohydrate per gram, preferably less than about 0.12 grams of carbohydrate per gram of food composition, or food coating.
Low digestion and absorption carbohydrates refers to sugar alcohols which are not as digestible or as readily absorbed as corresponding carbohydrates which are fully digestible.
[0017]In one embodiment, the composition maintains a glass transition temperature of about 95F and above at a target moisture in the range of 1 to 4 percent; thus, ensuring processing capability and shelf-life through distribution and storage. In another embodiment, the compositioi maintains a glass transition temperature of at least about at a target moisture at about However, it should be understood that any glass transition temperature sufficiently high to avoid or reduce cold flow is acceptable. The minimum Tg to provide acceptable reduced cold flow is about 80°F product storage temperature, usually about room temperature (70F) plus 10 degrees). It should also be understood that the target moisture may vary according to cooking conditions such as pressure, ingredients, etc. In any case, target moisture may vary so long as a sufficiently high glass transition temperature is achieved such that cold flow is reduced or completely avoided. Avoidance/reduction of cold flow in the sugar alcohol mixtures advantageously increases shelf-life for food products utilizing such sugar alcohol mixtures.
0 [0018]Additionally, the mixtures described herein have been formulated to deliver N pleasing organoleptic properties. For example, in one embodiment, the sugar alcohol Scoating is clear and transparent; thus, allowing for nut/seed visibility. In another embodiment, the coating delivers a sweet-savory flavor. In another embodiment, the coating is crispy-crunchy. In another embodiment the coating is light, i.e. "melt-in-yourmouth". Different variations of the sugar alcohol coating may include any combination of 0 0 the aforementioned properties, as well as additional properties.
S[0019]Although the sugar alcohol blends described herein may be used with any number i.n of food products, the coating as described herein is especially useful as a coating/binder for Snut and/or seed bar snacks, cereal pieces, grains, cookies, crackers, and mixtures thereof.
In the case of nut and/or seed bars; however, the nuts and/or seeds may be whole or halved depending on the recipe. As a binder, the sugar alcohol blends may be used to bind the nuts and/or seeds. In one embodiment, the coating/binder comprises approximately 35% of the food product and the nuts and/or seeds comprise the remaining However, it should be understood that any ratio of coating/binder to nuts and/or seeds may be used. In another embodiment, the food product containing a coating/binder, as described herein, and nuts and/or seeds may be wholly or partially enrobed in chocolate, caramel, and the like. In the case that a caramel, chocolate, or other-layer is added to the snack bar, the ratios may vary from the aforementioned coating/binder to 6 5 nuts and/or seeds.
[0020]Sugar alcohols, also known as polyols, polyhydric alcohols, or polyalcohols, are the hydrogenated forms of sugars. For example, in the case of aldoses, the aldehyde group, i.e. -CHO, is replaced with a -CHzOH group. In the case of a ketoses, the ketone group, i:e. is replaced with a -CHzOH group. Sugar alcohols can be derived from sugars consisting of one or more simple sugars, such as for example, monosaccharides, disaccharides, and polysaccharides. Sugar alcohols may be characterized by their degree of polymerization A monosaccharide based sugar alcohol is characterized as DP1 while a disaccharide based sugar alcohol is characterized as DP2. A polysaccharide is a sugar consisting of three monosaccharides or more and the corresponding sugar alcohol is
I
characterized as DP3. Examples of DP1 sugar alcohols include sorbitol (also known as glucitol), erythritol, mannitol, and xylitol. Another monosaccaride that may be used includes Tagatose (an isomer of glucose which is not a sugar alcohol). Examples of DP2 sugar alcohols include isomalt, maltitol, and lactitol. Examples of DP3 sugar alcohols include hydrogenated maltotriose.
[0021]In another embodiment a sugar alcohol/polysaccharide pre-blend is blended with isomalt to provide a food composition that can also be used as a coating. In this aspect, the sugar alcohol/polysaccharide pre-blend is blended with isomalt in an amount effective to provide a food composition with a Tg of 95F or greater at a moisture content of about 1 to about More specifically, about 10 to about 50 weight percent, preferably about to about 30 weight percent alcohol/polysaccharide pre-blend is blended with about to about 90 weight percent, preferably about 70 to about 80 percent isomalt. Isomalt used to partially replace maltitol in the coating increases Tg and decreases hygroscopicity of the binder. However, isomalt alone has a reduced Tg compared to the preblend plus isomalt. Furthermore, isolmalt tends to be brittle, have low sweetness and not be as well tolerated in the human digestive system.
[0022]One example of an alcohol/polysaccharide pre-blend is Lycasin® HBC available from Roquette America Inc.. Lycasin® HBC is a maltitol syrup that is comprised of maltitol and hydrogenated polysaccharides of closely controlled size distribution. The carbohydrate formulation gives Lycasin® HBC a unique set of properties that facilitates processing and provides sugar-free food products. The composition of Lycasin® HBC is as follows: 0 Sorbirol max) =DP1H 00 tt~Maltitol DP2H Hydrogenatedo ogsaccharides DP3H (low level) Hydrogenated polysaccharides =DP3'H (40-50%) Dry substance: 73% Reducing sugars: 0.15% max [00231 For more information pertaining to Lycasin®b HBC see "Lycasin® HBC: An1 unique maltitol syrup for sugar-free hard boiled candies" of Roquette America, Inc., incorporated herein by reference. Lycasin HBC at 4.7% moisture has a Tg of 128.7 0
F.'
100241 Isomalt is a 98% pure coarse white powder derived exclusively from sucrose.
Chemically, isomalt belongs to the class of disaccharide polyols like maltitol and lactitol.
Isomalt consists of two components in a 1: 1 ratio, 1,6.;glucopyranosyl-D-sorbitol
(OPS)
and i, 1-glucopyranosyl-D-mannitol (GPM). Isomalt is chemically stable and, thereforei resists Maillard reactions (browning). Pure isomalt has a low water solubility (28% at This solubility increases with increasing temperature. An isomalt syrup available from Cerestar,(ClsoMaltidex LQ 16510) -exhibits similar properties as isomalt powder, but does not require the disolution step during the manufactiuring of confectionery products.
Isomalt based candies tend not to absorb water. This stability against moisture pick-up hygroscopicity) contributes to an extended shelf life of the products. Isomalt-based hard candies show a better storage stability than other t-raditional hard-boiled sweets.
[00251 The glass transition temp erature (Tg) of isomalt is above room temperature. For example, the Tg of Isomalt ST at a moisture of 3.7 7% is about 1, 187F. Therefore, at room
I
temperature isomalt is in a glassy state and will notcrystallize (since crystallization can only occur at temperature above Tg).
[0026] In another aspect, a sugar alcohol/polysaccharide pre-blend maybe blended with S maltitol to provide a food composition. In this aspect, about 20 to about 80 weight percent, preferably about 40 to about 50 weight percent alcohol/polysaccharide pre-blend 0 is blended with about 20 to about 80 weight percent, preferably about 50 to about 00 t n weight percent maltitiol. Maltitol has a sweet, melt-in-your-mouth characteristic, much Slike sugar. Maltitol gives a crispy, crunch texture and is well tolerated by the human 3 digestive system.
N [0027]In one such aspect, Lycasin®, HBC is blended with maltitol. Maltitol powders or syrups range from 50 to 89% in maltitol purity. Maltitol has no aftertaste like some of the other polyols. Like other polyols, maltitol is slowly absorbed by the system and maltitol is available from Cerestar, Roquette, SPI Polyols, Inc. and Towa Chemical Industry Co.,
LTD.
[0028]In another aspect, a coating may be provided by blending less than about weight percent, preferably 20 to 30 weight percent matitol with isomalt. Additonal polysaccharides would not be needed in the blend..
[0029]Turning now to Figure 1, a process diagram for one embodiment of the production of low-carbohydrate peanut bar is shown. Shown are a dry rbaster 1, a nut feeder 3, a nut hopper 5, mixing kettle 7, staging kettle 9, flow meter 10, coil cooker 11, flash chamber 13, screw mixer 15, depositor 17, belt 19, and tamper 21.
[0030]The peanuts and binder/coating composition are prepared separately. Peanuts are roasted in the dry roaster 1. From the dry roaster 1, the dried peanuts are dispensed through the nut feeder 3 into the nut hopper 5. From the nut hopper 5, nuts are transferred to the screw mixer 15 where the nuts are combined with the binder/coating mixture.
[0031]Separately, raw materials for the binder/coating composition are manually weighed and added to the mixing kettle 7 where the ingredients are thoroughly mixed and heated
I
to 230"F (plus or minus 3YF). From the mixing kettle 7, the mixture is pumped into the staging kettle 9. The temperature in the staging kettle 9 is maintained at 200°F to 230°F, Spreferably 222°F to 228 0 F. The binder/coating base is transferred through a coil cooker 0 11 where the product temperature is increased to approximately 340 F to 360°F, preferably 347 0 F to 353 0
F.
S[0032]Flow rate through the coil cooker 11 is controlled using a feedback loop from a 00 t n mass flow meter 10 located between the staging kettle 9 and the coil cooker 11. In order 0 to maintain the cook temperature in the coil cooker 11 at about 340°F to about 360"F, preferably 347°F to about 353 F, steam pressure in the coil cooker 11 chamber is held at 0 150 (plus or minus 5 psig). The desired flow rate of the cooked binder/coating is 7.75 pounds per minute. For example, assuming the moisture content of the uncooked binder/coating mixture is 24.35% and the finished "cooked" binder/coating mixture is a moisture target of 9.72 pounds of binder/coating per minute is fed into the coil cooker 11, thus achieving a flow rate of 7.75%. From the coil cooker 11, the product is discharged into the flash chamber 13 where excess vapor is removed and the cooked binder/coating mixture drops into the screw mixer [0033]Color, flavor, peanut oil, and peanuts are metered into the screw mixer 15. All of the ingredients are mixed together and discharged via the depositor 17 unto a stainless steel belt 19 where the food product is formed into sheets approximately 0.5 inches thick and 40 inches wide by way of the tamper 21.' The food product is cooled on the belt 19 into two cooling zones. The front end of the belt 19 is held at about 110°F to about 130"F, preferably about 117°F to about 123°F, and the back end is held at about 85°F to.
about 105°F, preferably 92"F to about 98°F. The food product is cut into bars and transferred to the packaging area where they are wrapped.
[0034]This production procedure is advantageously designed to work with commonplace manufacturing facilities such that minimal modifications are needed. Although described for use with peanuts, is should be understood that the aforementioned process maybe used with other types of nuts and/or seeds.
