The invention relates to a novel proteinaceous material and foods made from the material, wherein the material has controllable functional characteristics including high to low adhesion, high to low tensile strength, high to low volume expansion, and high to low elongation strength.
Many food products, including but not limited to chips, bars, snacks, crackers, wafers, flat breads, cookies, biscuits, breads, bagels, cakes, muffins, waffles, pancakes, french fries, meat analogs, pasta, pastries, and doughnuts, have developed/evolved over the centuries with a focus on carbohydrate-based material formulations. This focus on carbohydrates (including but not limited to flour, sugar, starch, and derivatives of such) and their functional properties has had a major impact on manufacturing processes and equipment. Equipment materials of construction, equipment design, material handling requirements and systems, process design, recipe creation and product formulation have all developed around carbohydrate-based product formulation. Most importantly, though, these carbohydrate-based product formulations have made a permanent impact on the mind of the consumer regarding food product taste, texture, and mouth-feel. Unfortunately, this focus on carbohydrate-based foods has also had other unwanted consequences, including an out-of-control increase in obesity, irritable bowel syndrome, diabetes, and lethargy. Many of these diseases are scientifically linked to the high-carbohydrate diet common in the western hemisphere.
As a result, the need for changes to the high-carbohydrate diet has become critical for the general publics' long-term health and wellness. The difficulty with enacting the necessary product formulation changes is that a change in food ingredients is usually not simple, nor just an easy substitution of one ingredient for another. Foods must still be palatable and digestible, and the products must be capable of being successfully processed on existing manufacturing equipment, ranging from home kitchen appliances to large industrial scale equipment. Additionally, this material technology must be balanced, for it needs to not only meet the requirements of the equipment, but it must ultimately yield a food product with taste, texture and mouth-feel characteristics similar to existing carbohydrate-based food products.
Any new food material technology would thus need to be multifunctional, requiring it to both process and taste similar to carbohydrates. Also, in order to be processed, such foods would need to emulate the material characteristics exhibited by high-carbohydrate foods, including possessing controllable extensibility/elongation, volume expansion, and adhesion properties needed to be processable in common food manufacturing processes, including direct reduction sheeting, lamination sheeting, extrusion, and various molding processes. The processed food materials need to be physically subjected to equipment handling, various extrusion techniques, and thickness reduction methods on automated process equipment to measurements ranging from 300 mm to as little as 0.10 mm. Standard carbohydrate materials technology, used for these common food processes, has been mastered over centuries of engineering, work, and effort. Therefore, these processes and the equipment have been designed for processing of high-carbohydrate products. There is thus a great need for a material base change in food processing which will yield good tasting, economical, high-protein, reduced high glycemic/simple carbohydrate foods.
The invention relates generally to a novel proteinaceous food material technology. The material has controllable, engineered process-related functionality, including high to low break elongation, high to low tensile strength, high to low expansion, and high to low adhesion. The material also possesses good die cutting characteristics, molded form retention, is edible, and forms a protein-based dough-like material when blended with water that is processable much like a high-carbohydrate dough. The material can be formulated to work within numerous existing food process systems, including direct reduction sheeting, lamination sheeting, single and twin screw extrusion, die cutting, and molding processes followed by baking, drying, boiling, steaming, frying, seasoning, enrobing, and/or a combination of such. The final fabricated food mimics a high-carbohydrate food product such as chips, bars, snacks, crackers, wafers, flat breads, cookies, biscuits, breads, bagels, cakes, french fries, waffles, pancakes, muffins, meat analogs, pasta, pastries, and doughnuts.
This novel material technology is based on the utilization of a modified non-viscoelastic wheat protein isolate, in combination with other desirable proteinacious materials, optional low to moderate percentage levels of select carbohydrates, a liquid source, and in some cases amounts of fats. The proteinaceous material technology is edible, and when mixed with water or other liquids, forms a dough-like food material. This dough-like food material's controllable functionality is based on the amount of the modified non-viscoelastic wheat protein isolate relative to the other formulation ingredients. The relative amount of the modified non-viscoelastic wheat protein isolate directly imparts the controllable functional characteristics, useful both for processing and in the final product. These controllable functional characteristics include high to low elongation, high to low tensile strength, high to low volume expansion, high to low adhesion, die cutting characteristics, and molded form retention. The control of these functional characteristics, particularly in the break elongation, plays a major role in the processing of the raw material. These characteristics also play a role in the texture, shape/look, nutritional profile, and organoleptics of the final food products.
The novel material engineering plays a critical role in all stages of numerous food process systems ranging from kitchen scale through to the largest industrial scale operations. However, the materials of this invention are particularly engineered for the equipment of large, industrial-scale processing systems that have been designed to process high-carbohydrate foods. The properties for which these processes are designed include elongation control, tensile strength, adhesion control, volume expansion control, mixing, molded-form retention, die cutting/dockering and release, and the ability to be pumped.
The relative ratio of modified non-viscoelastic wheat protein isolate to co-ingredients creates in the raw material the different carbohydrate-like characteristics. The data set forth below demonstrates control of elongation by variation of the amount of modified non-viscoelastic wheat protein isolate.
Examples of non-viscoelastic modified wheat protein isolate for the invention include an isolated source that is greater than 70% protein measured on a dry basis using the common measurement formula: N×6.25. This invention can be accomplished with chemically and/or enzymatically modified wheat protein isolate that possess non-viscoelastic characteristics. Examples of desirable additional proteinacious materials for the invention include soy protein isolate, whey protein isolate, milk protein isolate, calcium caseinate, sodium caseinate, soy protein concentrate, textured wheat protein, textured vegetable protein, whey protein concentrate, rice protein concentrate, egg protein, zein, wheat protein concentrate, denatured proteins, gluten, oil seed proteins, hydrolyzed proteins, cheese, textured proteins, fish protein, amino acids, peptides, collagen, casein, animal protein, single cell protein, flax protein, flax meal, and other raw materials having a protein content of greater than 25%. Examples of fats that can be used in the invention include vegetable oils, legume oils, lecithin, butter, cheese curds, natural cheese, process cheese, shortening, or other materials with a percent fat greater than 33% measured on a dry basis. Examples of carbohydrates that can be used in the invention include, but are not limited to, fiber, gums, starches, pregelatinized starches, crystalline starches, powdered flavors, spices, herbs, texturizing agents, beta glucan-based materials, corn masa, modified flour, dried potato material, grain flours, legume flour, seed meal, seeds, vegetable matter, and other CHO compounds. Other proteins and fats could also be used. The above are preferred, because they are widely available commercially, and also contribute to the final products' desirable nutritional profile and/or taste.
The invention consists generally of the following: mixing of the non-viscoelastic modified wheat protein and other proteinaceous material(s), fat (s), desired/selected carbohydrate(s) (if any), and water (and steam if necessary), in a mixing vessel and/or extruder barrel (or preconditioner) to form a soft/moist, extensible, non-sticky dough. The dough is then extruded through a die (and cut to a desired shape and size) and/or transferred to a sheeting, lamination sheeting, or rotary molding process, followed by the reduction and transformation of the raw dough into the desired shape and thickness, for processing into the final product. Optionally, this can be followed by the cutting/forming of the dough into the desired end product shape and size through the utilization of a cutting die or rotary cutter or guillotine cutting system. The product is then transferred to a tunnel oven, drying, microwaving, frying (including vacuum frying), steaming, or boiling process, or combination two or more of such, at temperatures less than 900° F. but greater than 100° F. The product is processed in this manner until the final item reaches the desired moisture percentage of less than 25%, with the preferred moisture content level being from 1% to 20%.
In the preferred embodiments, the mixture ratios of proteins, proteinaceous materials, fats, and carbohydrates, to final product weight can be modified for increased or decreased final nutritional levels as well as functional properties of the food material. However, the ratio of the modified wheat protein to final product weight must be maintained at greater than 5% and less than 50%, with the preferred being 7% to 45%. Mixing of the proteins, fats, and select carbohydrates is preferably accomplished by adding all components directly into a single chamber, mixing by a single or double arm mixing device (including a ribbon blender) or by direct feed mixing in the barrel of an extruder, and mixing/blending until thoroughly integrated. The water percentage of the dough mixture will vary according to ingredients, protein composition, type of protein, solubility of protein, fat percentage, temperature of surrounding environment, and method of processing. The preferred water to solids mixture is from 1:1 to 1:5. The final dough product will be solid enough to be reduced to a solid sheet or molded item or extruded product, utilizing the sheeting, molding, and extrusion process equipment, with a thickness of greater than 0.10 mm and less than 300 mm, without sheer adhesion to the reduction rollers, rotary molding system, or extrusion screw/barrel/die head unit. Optionally, for varied sheer requirements, the equipment systems may be coated with a non-stick coating, such as Teflon or lecithin based anti-adhesion product, to avoid friction induced dough adhesion. The final formed and cut proteinaceous food items are then processed through baking, drying, frying, microwaving, steaming, boiling, or a combination of such, for moisture reduction. The final moisture content should be 1% to 7% for shelf stable products such as chips, bars, snacks, crackers, wafers, flat breads, cookies, pasta, biscuits, cereals, with a preferred 2% -6.5% to avoid scorching and burning. The final moisture content should be 3% -30% for breads, bagels, cakes, pastries, french fries, meat analogs, food pellets, and doughnuts. Higher quantities of moisture reduce the shelf stability. Topical seasonings, icings, coatings and/or oils/fats may then be added to the protein food product for increased flavor.
The use of this extensible dough with existing equipment in a commercial bakery, extrusion, pasta, or snack food plant allows for high volume production of a product that is traditionally difficult to produce at economical costs due to the fragility and lack of extensibility of protein dough products.
This invention features an extensible, pliable, non-viscoelastic, proteinaceous, reduced carbohydrate dough material for the production of fabricated, reduced carbohydrate proteinaceous foods, comprising a modified wheat protein isolate, at least one additional proteinaceous ingredient, and water, wherein the ingredients are mixed together to form the dough material.
The modified wheat protein isolate is preferably modified to achieve broken disulfide bonding providing a non-viscoelastic characteristic to the protein. The modified wheat protein may possess a protein content of greater than 70% calculated as nitrogen×6.25. The modified wheat protein may be a wheat protein isolate with a carbohydrate percentage no more than 25%, ash percentage no more than 2%, and fat content no more than 3%. The modified wheat protein may have an average molecular weight of less than 100,000. The modified wheat protein may be film forming. The modified wheat protein may be highly refined and sodium metabisulfite-modified wheat gluten. The modified wheat protein may constitute from about 5% to about 50% by weight of the final product.
The additional proteinaceous material may comprise one or more proteins including but not limited to soy protein isolate, whey protein isolate, milk protein isolate, calcium caseinate, sodium caseinate, soy protein concentrate, textured wheat protein, textured vegetable protein, whey protein concentrate, rice protein concentrate, egg protein, zein, wheat protein concentrate, denatured proteins, gluten, oil seed proteins, hydrolyzed proteins, cheese, textured proteins, fish protein, amino acids, peptides, collagen, casein, animal protein, single cell protein, flax protein, flax meal, and other raw materials having a protein content of greater than 25%.
The dough material may further comprise one or more select carbohydrates, one or more fats, one or more emulsifying agents, and one or more flavors. The dough material may further comprise one or more leavening agents. The dough material may have a reduced carbohydrate profile of less than 70% of the dough by dry weight. The dough material may be at least partially processed by one or more of the following processes: direct reduction sheeting, lamination sheeting, rotary molding, die cutting, baking, drying, microwaving, frying, steaming, boiling, and extrusion.
The invention also features a fabricated proteinaceous food product made from this dough material. The food product may comprise greater than 25% by dry weight protein. The food product may be selected from the group of food products consisting of chips, bars, snacks, crackers, wafers, flat breads, cookies, biscuits, breads, bagels, cakes, french fries, meat analogs, pasta, pastries, breakfast cereals, pancakes, waffles, pizza dough, muffins, and doughnuts. The food product may further comprise a topical seasoning/coating. The food product may further comprise an enrobed covering.
This invention features an extensible, proteinaceous formulation of modified wheat protein, proteinaceous materials/concentrates/isolates, fats/oils, and less than 75% select carbohydrates having controlled break elongation functional characteristics; the blending of such ingredients in a mixer; the conversion to an extensible reduced carbohydrate, high protein dough through the addition of water and thorough mixing; the transfer, reduction and/or molding of the dough to a desired thickness and shape through extrusion and die cutting and/or reduction sheeting and/or lamination sheeting processes and die cutting, direct deposit, and/or rotary molding (e.g., rotary piston molding); followed by baking, drying, microwave, frying, steaming, boiling, or a combination of such for desired moisture reduction and proteinaceous matrix curing/setting, with the option of topical seasoning/coating of the final product.
The invention consists generally of the following: mixing of a reduced carbohydrate protein blend consisting of modified wheat protein(s) and proteinaceous concentrates and/or isolates, and/or fats and oils, and/or lecithin, and/or select carbohydrate materials, if desired for flavor and/or texture and/or seasoning and/or bulking and/or gelatinization; the addition of water to the blend to form a soft, extensible, cohesive, non-adhesive dough; followed by the transfer of the moist yet solid dough to an extrusion, reduction sheeter system, lamination sheeting, direct deposit, and/or rotary molding system, for final product depositing or dough forming/sheeting/molding to a thickness from 300 mm to 0.10 mm. The reduced thickness dough is then optionally processed by a die cutting device for the cutting/formation of the protein chips, bars, snacks, crackers, wafers, flat breads, cookies, biscuits, breads, bagels, cakes, french fries, meat analogs, pasta, pastries, and doughnuts. The extruded dough can optionally be combined with another product such as a fruit paste, and/or the individual cut/deposited unit items can be placed directly onto a conveyor band. The items are then transferred to a moisture-reduction process, including baking, drying, microwaving, frying, steaming, boiling, or a combination of such, until the extensible protein based food reaches the desired moisture percentage for durable handling strength, shelf stability, texture, flavor, and crunch. The final fabricated proteinaceous food can then be optionally seasoned, flavored, layered, and/or enrobed with a topical seasoning and/or coating, and then packaged.
The following tables illustrate the elongation of the inventive dough that allows it to be processed on small kitchen and industrial-scale food processing equipment designed for processing carbohydrate-based products.
The three doughs were prepared using the sodium metabisulfite, chemically modified, non-viscoelastic, film forming wheat protein isolate FP 5000 from Midwest Grain Products labeled “W”. This product has 90% minimum protein (N×6.25), 4% maximum ash, 7% maximum moisture, 2% maximum fat, 1% maximum fiber, and 5% maximum starch. It has an average molecular weight of less than 100,000 Daltons. The doughs also include a common soy protein isolate Profam 781 from Archer Daniels Midland labeled “S”, and a common vegetable oil labeled “O” and room temperature process water labeled “PW” under standard room temperature (70°-78° F.) conditions.
As is evident, the use of at least 11% modified wheat protein isolate dramatically increases the break elongation functional characteristics of the proteinaceous dough, thus allowing it to have properties necessary for many industrial/commercial processes .
