Description

Restructured Natural Protein Matrices This ation claims priority benefit of application serial No. 61/852,465 filed March 15, 2013, the ty of which is incorporated herein by nce.
Background of the Invention.
Structural transformations are an important part of the modern food industry. Raw als are changed into refined food ts by processing agricultural output. A major objective of food structuring is to recombine food components for improved utilization of food resources. Alternatively, from an economic prospective, such restructuring can be designed to yield products deemed more valuable in the market place.
More specifically, restructuring is directed to four basic food components: water, proteins, fats and carbohydrates. Micronutrients (e. g., vitamins and minerals) and other microcomponents such as , colors, preservatives and other functional additives (e. g., stabilizers, emulsifiers, etc.) are often introduced at some point during the restructuring process. Regardless, of the four basic components, restructuring ses are most often ed to proteins and starches. Reasons underlying n and starch restructure include a worldwide demand for dietary protein and carbohydrates and higher prices associated with these foods, thereby supporting higher profit margins and corresponding economic activity.
The preparation and subsequent use of soy milk, basically a sion of ground soybeans and water, is well-known and illustrates several widely used techniques for protein restructuring. While soy milk can be consumed as a beverage or ted, it is more often used as a starting material for several other structured food products. For instance, tofu is prepared by precipitating soy milk proteins with a calcium salt to form a coagulum that is then d, pressed and washed to yield a proteinaceous food product.
Various other restructuring techniques can be considered in the context of comminuted meat products, whereby an oil-in-water emulsion is ped in a gel of insoluble proteins and muscle fibers. A raw meat protein matrix system, typically low-value, high-connective tissue meat cuts or trimmings, is ground to reduce particle size. After initial grinding, the meat protein matrix is d with various emulsifying salts (e.g., phosphates, etc.) and other ingredients to promote extraction of a myofibrillar binder. Such muscle proteins bind better under elevated temperature conditions. In these processes, cooking serves to reactivate the n binder, recombine the ground particles and complete the restructuring process. Such meat-emulsions are quite stable, but even if coalescence does occur, nt of the fat globules is confined by the restructured protein matrix.
Cheese rates other aspects relating to protein cturing. From a historical perspective, process cheese was initially developed to s homogeneity and shelf-life issues inherent to natural cheese. While natural cheese is made directly from milk, process cheese is produced by blending one or more natural cheeses in the presence of fying agents and, optionally, other dairy and non-dairy ingredients. Heat processing with continuous mixing leads to a more neous product with extended shelf life.
Under the United States Code of Federal Regulations (CFR), process cheese is a generic term including pasteurized process cheeses, pasteurized process cheese foods and pasteurized process cheese spreads, all of which are regulated on the basis of process ters, ingredients, fat and moisture content and the like. (See, 21 CFR 133.169 - 133.180.) Together with choice of natural cheese (e.g., with respect to age, flavor, etc.), selection of an appropriate emulsifying agent is a key consideration in determining the physiochemical and functional properties of a resulting process cheese.
Currently, thirteen emulsifying agents (either alone or in ation) are approved for use: mono-, di-, and trisodium phosphates, dipotassium phosphate, sodium hexametaphosphate, sodium acid pyrophosphate, tetrasodium pyrophosphate, sodium aluminum phosphate, sodium citrate, potassium e, calcium citrate, sodium tartrate, and sodium potassium te. The most common emulsifying salts used for process cheese cture in the United States are ium citrate and disodium phosphate. Trisodium citrate is the red emulsifying salt for slice-on-slice s cheese varieties, whereas disodium phosphate (or appropriate combinations of di- and ium phosphates) is used in loaf-type process cheese and process cheese spreads. In certain applications, low levels of sodium hexametaphosphate are also used along with these emulsifying salts. Sodium aluminum phosphate is frequently used in conjunction with mozzarella type imitation process cheese varieties to replace mozzarella on frozen pizzas. Regardless, the weight of the solids of such an emulsifying salt or salts is not more than 3 percent of the weight of a corresponding CFR—defined process cheese. (21 CFR § 133. l69(c).) Emulsifiers used in process cheese not defined by the CFR follow the tenants of being safe and suitable.
Generally, emulsifying salts serve to sequester calcium and adjust pH.
Both fimctions assist hydration of proteins present in natural cheese, to tate interaction with the aqueous and fat phases, thereby producing a more homogeneous emulsion. More specifically, the function of such salts can be understood by contrasting it to natural cheese production. Bovine milk is characterized by four major types of casein proteins: sein, sein, B-casein and K-casein--each of which is amphiphilic, with hydrophobic and hydrophilic components, and containing covalently-attached phosphate . In an aqueous emulsion environment, milk caseins adopt a micellular configuration stabilized by protein-protein hydrophobic interactions and colloidal calcium phosphate-mediated cross- linking. K-casein is primarily present on the micelle surface, with the hydrophobic component embedded therein and a negatively-charged hydrophilic component directed outward into the aqueous phase. Micelles repel each other, thereby stabilizing the emulsion.
During natural cheese production, enzymatic (e.g., rennet) action on K-casein cleaves the hydrophilic component destabilizing the micelles. Calcium-mediated cross-linking between phosphoserine residues of the 0L- and B-caseins produces a network of water-insoluble calcium-paracaseinate phosphate complexes, commonly referred to as curds, with the fat phase suspended therein.
In contrast to natural cheese, process cheese can be described as a stable oil-in-water emulsion. Emulsifying agents, such as the salts described above, e casein emulsification by--in conjunction with continued heating and mixing--displacing the calcium ate complexes and dispersing the calcium-paracaseinate phosphate network. The dispersed network interacts with the fat phase and, upon cooling, es a process cheese structure--new and distinct from a natural cheese structure with a fat phase emulsified by a m protein gel.
The resulting stable, homogeneous process cheese ure affords a wide range of t forms (e. g., loaves, slices, grates, shreds, spreads and the like) and a corresponding range of end-use applications in the food preparation and service industry.
However, the prior art recognizes a number of drawbacks and ncies, several of which can be ly related to the use of emulsifying salts. For instance, unsightly crystal formation is observed and has been linked to the relative insolubility of s phosphate and citrate salts, as further influenced by pH or storage conditions. From a more functional perspective, oil separation can result from improper salt content in ction with pH, casein level and s temperature considerations. Further, ed and melted textural ties ofprocess cheese can be adversely affected by choice of emulsifying salt. Perhaps most consequential, adverse consumer perceptions are drawn from inclusion of fying salts (e. g., pyrophosphates, aluminum phosphates, etc.) on product labels. [001 1] Accordingly, together with other long-standing issues related to process cheese, there remains an on-going n in the art to provide a cheese product affording 2014/030879 selected s of process cheese without disadvantages associated with use of emulsifying salts.

Detailed Description of Certain Embodiments.
Various non-limiting embodiments of this invention can be considered with reference to the schematic rt of Figure l. A starting natural cheese material is treated with food grade aqueous base of sufficient concentration and volume, with mixing, to provide a modified cheese matrix ofpH about 5 to about 12.5. In certain embodiments, ing upon ng material and desired restructured cheese product, the matrix is modified and the pH can be about 8 to about 10. Thereafter, with mixing, a unique formulated ng ition is introduced to adjust matrix pH, structure and/or functionality depending on desired cheese y. As discussed above and illustrated below, such a flavoring composition can be formulated to e a food grade proton donor or Lewis acid component. In doing so, the elastic properties of the restructured matrix can be either maintained so as to approximate those of the natural cheese starting material or altered to provide new visco-elastic ties and related textures. Regardless, continued processing of the restructured cheese product can include cutting, slicing, shredding, mixing, grinding, heating and/or dispersing the restructured product, or incorporating into a prepared food product prior to packaging or distribution.
As used herein, the term "visco" pertains to the rheological parameters of materials such that imparted stress energy and the resultant strain energy is dissipated into the material in the form of heat. [003 1] Also, as used herein, the term "elastic" pertains to the rheological parameters of materials such that ed stress energy and the resultant strain energy is stored in the al and can be red fully upon removal of the stress.
Also, as used herein, the term "visco-elastic" pertains to rheological parameters of materials such that imparted stress energy and the resultant strain energy has both a partial stored strain that can be recovered upon removal of the stress and a l strain energy that is dissipated into the material in the form of heat. Various instruments and methods can be used to measure or observe visco-elastic properties, such instruments including, but not limited to, eters, penetrometers, shear force cutting machines, flow s, as well as melting tests or recipes having numeric or judgmental evaluations.
As discussed above, certain embodiments of this invention can be undertaken at ambient temperatures or pressures. Nonetheless, depending upon any particular cheese starting material, reagent, additive or restructured cheese product desired or combinations thereof, any process step, including matrix modification or matrix restructuring, or both, can be conducted at temperatures from about -20 0C to about 140 oC and at pressures from 0 to about 15,000 psi. Any such method step can be med under pressure or vacuum, optionally with cooling or upon heating or an appropriate time or at a time at least lly sufficient to achieve a d intermediate, end result or both. For instance, application of suitable pressure, at an appropriate temperature, structure, density or texture, or a combination thereof, can be imparted to obtain a desired restructured cheese product.
Figure l is provided only by way of illustration and is not intended to limit the scope of this invention in any way. A starting cheese material can be selected from s cheddar, monterey jack, swiss and mozzarella-type cheeses and combinations thereof, together with other cheeses of comparable relative value as would be understood by those skilled in the art made aware of this invention. For ce, such a starting material can be any cheese by-product of trims tion from cut-wrap operations, or any cheese material in or out of rd specification ed in trade for a given cheese variety. Selection can also take into consideration moisture and fat content of any one or more cheese starting materials or restructured cheese products. With regard to the latter, methods of this invention can be specifically designed and tailored to e, t limitation, particular cheddar, parmesan, romano, provolone, swiss, gouda, camembert, mozzarella or blue-style restructured cheese ts. From an economic perspective, such a product can be selected from these and various other cheeses of higher relative value as compared to a starting material from which it was prepared. Such restructured products are limited only by a corresponding flavoring composition and the flavor components thereof.
In addition to the aforementioned cheese , ate, tofu, fruit, vegetable, fish, meat, cured meat such as but not limited to bacon, sausage, sourdough, beer, wine, lic spirit, surimi, legume paste flavors and combinations thereof can be introduced. Regardless, a wide range of other additives can be incorporated with such a starting al to affect structure, flavor, preservation, nutrient value, stabilization, color or any ation thereof. Any such additive can be introduced at any process point, but preferably at a point before, during or after matrix modification or, alternatively, at a point before, during or after matrix restructuring. Such additives include but are not d to flavors, , ts, fruits, meats, enzymes and combinations thereof. Further, s probiotics can also be uced, alone or in conjunction with other additives, such probiotics including live or deactivated microorganisms, such as eukaryotes, prokaryotes, yeasts, fungi, molds, protozoa and combinations of such live and deactivated microorganisms.
