Definitions

  • the invention is directed to an egg substitute and a method of manufacturing the same, and compositions comprising the egg substitute, including edible compositions such as baked goods.
  • Eggs are a versatile and near ubiquitous food and food component.
  • the market for egg ingredients has been estimated to be $1.8 billion domestically and $6 billion globally, and continues to grow.
  • Eggs are highly valued for numerous reasons.
  • Eggs not only provide high nutritional content, they are also an essential component of a wide range of food products, ranging from, but not limited to: breads, cakes, cookies, custards, souffles, muffins, scones, biscuits, pasta, dressings, sauces, and ice cream.
  • eggs have a number of drawbacks.
  • eggs contain high levels of cholesterol and saturated fats, which increases risk for cardiovascular diseases and obesity.
  • eggs have limited shelf life, and are at risk of harboring infectious pathogens, such as, for example, Salmonella, E. coli, and other pathogens which may endanger public health.
  • infectious pathogens such as, for example, Salmonella, E. coli, and other pathogens which may endanger public health.
  • Many attempts have been made to create an egg substitute that recapitulates the desired features of natural eggs while minimizing the unwanted features of eggs. These attempts range from home-cooking based substitutes, e.g., mashed bananas and/or applesauce to replace eggs in baking, baking powder/baking soda mixtures to provide leavening, flour/water mixtures to provide binding and leavening.
  • Commercially available substitutes include, for example, EggbeatersTM, Ener-GTM egg substitute, Bob's Red Mill Egg ReplacerTM. However, all of these substitutes have certain limitations.
  • compositions that can be used as a whole egg substitute, driven by molecular gastronomy.
  • the compositions replace the whole egg or a part of the egg (e.g. the egg white or the yolk) in food products on a 1 : 1 basis by weight after reconstitution with water or other liquid, has a nutritional profile similar to eggs, and replicates one or more, if not alL of the egg's core functionalities.
  • the whole egg is understood to include the contents of the egg as poured from the shell of the egg.
  • the core functionalities can be, but are not limited to achieving a desired crumb density, structure/texture, elasticity/springiness, coagulation, binding, mouthfeeL leavening, aeration/foaming, creaminess, and emulsification of the food product.
  • the compositions can functionally replace the whole egg or a part of the egg in baked goods and/or emulsions.
  • the compositions replace whole eggs or a part of the egg on a 1 :5 basis by weight, wherein 1 weight unit of the compositions replaces 5 weight units of eggs.
  • the compositions replaces whole eggs on a 10: 1, 9: 1, 8: 1, 7: 1, 6: 1, 5: 1, 4: 1, 3: 1, 2: 1, or 1 : 1 basis by weight.
  • compositions replace whole eggs or a part of the egg on a 1 : 10, 1 :9, 1 :8, 1 :7, 1 :6, 1 :5, 1 :4, 1 :3, 1 :2, or 1 : 1 basis by weight.
  • the compositions may be used to replace egg yolks. In other embodiments, the compositions may be used to replace egg whites. In some embodiments, the compositions may be used as an egg substitute in non-food products, e.g., shampoos. In some embodiments, the compositions may be used to replicate desired functions of eggs while overcoming the limitations of natural eggs, e.g., high saturated fat content, high cholesterol content, and allergenic properties. In yet other embodiments, the compositions may be used for functions other than as an egg substitute, e.g., water binding function.
  • the composition comprises protein in an amount up to 80% by dry weight, and (ii) fat in amount from 5% to 15% by dry weight; wherein the composition is essentially egg-free, and wherein the composition provides binding, moisturizing, leavening, creaminess, and/or emulsifying properties similar to an egg.
  • the compositions comprises 10-20% protein and 5-15% fat by dry weight, wherein the composition is essentially egg free and can be used to provide binding, moisturizing, leavening, and/or emulsifying properties similar to an egg.
  • the protein comprises plant-based protein.
  • the plant-based protein comprises protein from garbanzo, fava beans, yellow pea, sweet brown rice, rye, golden lentil, chana dal, soybean, sorghum, sprouted green lentil, du pung style lentil, and/or white lima bean.
  • the fat comprises plant-based oils.
  • the plant-based oils comprise oils from garbanzo, fava beans, yellow pea, sweet brown rice, rye, golden lentil, chana dal, soybean, sorghum, sprouted green lentil, du pung style lentil, and/or white lima bean.
  • the composition comprises over 50% by dry weight of one or more flours, and less than 20% of a mixture of one or more gums and/or starches. In some cases, the composition comprises over 60% by dry weight of one or more flours, and less than 20% of a mixture of one or more gums and/or starches. In some cases, the composition additionally comprises 0-15% of a high fiber material. In some cases, the high fiber material comprises one or more brans. In a particular case, the one or more brans comprise micronized corn bran.
  • the compositions comprise 60-99.5%) of bean flour and 0.5-15% of a mixture of gums and/or starches by dry weight.
  • the bean flour comprises garbanzo flour.
  • the garbanzo flour comprises more than about 40%, more than about 75%), or more than about 85% of the dry weight of the composition.
  • the bean flour comprises fava bean flour.
  • the fava bean flour and garbanzo flour together comprise more than 80% of the dry weight of the composition.
  • the garbanzo flour comprises about 80-85% of the dry weight of the composition, and the fava bean flour comprises about 12.5-17.5%) of the dry weight of the composition.
  • the garbanzo flour comprises about 45-55% of the dry weight of the composition
  • the fava bean flour comprises about 35-45% of the dry weight of the composition.
  • the bean flour is essentially free of soy flour, or does not contain any soy flour.

Description

PLANT-BASED EGG SUBSTITUTE AND METHOD OF MANUFACTURE
[0001] This application claims priority under 35 U.S.C. 119 to U.S. Provisional Application 61/554,928, filed November 2, 2011, and to U.S. Provisional Application 61/621,425, filed April 6, 2012, the entire contents of each of which is hereby incorporated by reference.
FIELD OF THE INVENTION
[0002] The invention is directed to an egg substitute and a method of manufacturing the same, and compositions comprising the egg substitute, including edible compositions such as baked goods.
BACKGROUND OF THE INVENTION
[0003] Eggs are a versatile and near ubiquitous food and food component. The market for egg ingredients has been estimated to be $1.8 billion domestically and $6 billion globally, and continues to grow. Eggs are highly valued for numerous reasons. Eggs not only provide high nutritional content, they are also an essential component of a wide range of food products, ranging from, but not limited to: breads, cakes, cookies, custards, souffles, muffins, scones, biscuits, pasta, dressings, sauces, and ice cream.
[0004] However, eggs have a number of drawbacks. For example, eggs contain high levels of cholesterol and saturated fats, which increases risk for cardiovascular diseases and obesity.
Therefore, consumers that desire to reduce their risk of cardiovascular disease, or are otherwise concerned over maintaining a healthy diet and weight, represent an untapped market for eggs or egg- containing products. Other consumers that would benefit from the high nutritional content and enjoyment of egg-containing products may be prevented from doing so due to food allergies or other dietary restrictions. For instance, 1-2% of young children are estimated to be allergic to eggs. Significant population segments follow voluntary dietary restrictions, e.g., vegans and others may not eat eggs for religious or other reasons. In addition, the industrial scale production of eggs are associated with industrial farming of chickens, which incur high costs, such as, e.g., costs related to food health and safety restrictions for farmers, high transportation costs, and the cost of feeding and housing egg- laying birds. Furthermore, industrial chicken farming has a negative environmental impact, and raises a number of important humanitarian issues.
Moreover, eggs have limited shelf life, and are at risk of harboring infectious pathogens, such as, for example, Salmonella, E. coli, and other pathogens which may endanger public health. [0005] Many attempts have been made to create an egg substitute that recapitulates the desired features of natural eggs while minimizing the unwanted features of eggs. These attempts range from home-cooking based substitutes, e.g., mashed bananas and/or applesauce to replace eggs in baking, baking powder/baking soda mixtures to provide leavening, flour/water mixtures to provide binding and leavening. Commercially available substitutes include, for example, Eggbeaters™, Ener-G™ egg substitute, Bob's Red Mill Egg Replacer™. However, all of these substitutes have certain limitations. For example, many of the home-based egg substitutes provide only a single limited desired property of eggs in cooking, e.g., mashed fruit provide moisture and binding but not leavening, baking powder/soda and flour/water substitutes provide some leavening but limited binding properties. Eggbeaters™ is made from real egg whites, and is thus associated with low shelf life and risk of carrying pathogens, and is also avoided by vegans. Ener-G™ vegan egg substitute, acts as an imperfect substitute for many baking purposes because of its inferior binding qualities. Disclosed herein are compositions for use as a whole- egg substitute that addresses the limitations of the current art.
SUMMARY OF THE INVENTION
[0006] Disclosed herein are multifunctional compositions that can be used as a whole egg substitute, driven by molecular gastronomy. In some embodiments, the compositions replace the whole egg or a part of the egg (e.g. the egg white or the yolk) in food products on a 1 : 1 basis by weight after reconstitution with water or other liquid, has a nutritional profile similar to eggs, and replicates one or more, if not alL of the egg's core functionalities. In some embodiments the whole egg is understood to include the contents of the egg as poured from the shell of the egg. In some embodiments, the core functionalities can be, but are not limited to achieving a desired crumb density, structure/texture, elasticity/springiness, coagulation, binding, mouthfeeL leavening, aeration/foaming, creaminess, and emulsification of the food product. The
functionalities described above can overlap or may be interdependent. In some embodiments, the compositions can functionally replace the whole egg or a part of the egg in baked goods and/or emulsions. In some embodiments, the compositions replace whole eggs or a part of the egg on a 1 :5 basis by weight, wherein 1 weight unit of the compositions replaces 5 weight units of eggs. In other embodiments, the compositions replaces whole eggs on a 10: 1, 9: 1, 8: 1, 7: 1, 6: 1, 5: 1, 4: 1, 3: 1, 2: 1, or 1 : 1 basis by weight. In other embodiments the compositions replace whole eggs or a part of the egg on a 1 : 10, 1 :9, 1 :8, 1 :7, 1 :6, 1 :5, 1 :4, 1 :3, 1 :2, or 1 : 1 basis by weight.
[0007] In some embodiments, the compositions may be used to replace egg yolks. In other embodiments, the compositions may be used to replace egg whites. In some embodiments, the compositions may be used as an egg substitute in non-food products, e.g., shampoos. In some embodiments, the compositions may be used to replicate desired functions of eggs while overcoming the limitations of natural eggs, e.g., high saturated fat content, high cholesterol content, and allergenic properties. In yet other embodiments, the compositions may be used for functions other than as an egg substitute, e.g., water binding function.
[0008] In one aspect, the composition comprises protein in an amount up to 80% by dry weight, and (ii) fat in amount from 5% to 15% by dry weight; wherein the composition is essentially egg- free, and wherein the composition provides binding, moisturizing, leavening, creaminess, and/or emulsifying properties similar to an egg.

[0044] Functional Properties of the Compositions
[0045] Natural eggs have a number of useful properties that make them a useful component in a wide variety of food and non-food products. In some embodiments, the egg substitute will fulfill one or more qualities of natural eggs. In some embodiments, the compositions described herein will fulfill more than one quality of natural eggs. In more particular embodiments, the compositions disclosed herein will fulfill more than two, or more than three, or substantially most or all of the qualities of natural eggs. In various embodiments, binding, moisturizing, leavening, and/or emulsifying properties are determined to be similar to an egg if measured at between about 90-110% of the binding, moisturizing, leavening, and/or emulsifying properties of an egg.
[0046] Viscosity
[0047] Natural eggs can provide a desired viscosity to batter or dough for the preparation of baked goods. Viscosity can be qualitatively assessed by the rate or ease of flow, the ease of movement during handling, or may be quantitatively assessed by viscometers or rheometers. In some embodiments, the compositions can provide a desired viscosity to the batter or dough similar to batter or dough prepared using natural eggs. In some embodiments, the compositions provide about 1-30%, about 20-50%, about 30-70%, about 40-90%, about 60-100% of the desired viscosity of a natural egg. In some embodiments, the compositions provide more than about 1%), about 2%, about 3%, about 4%, about 5%, about 10%, about 15%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, about 100% of the desired viscosity of a natural egg. In some embodiments the viscosity is in a raw product. In some embodiments the viscosity is in a cooked product. In some embodiments the viscosity is in a chemically crosslinked product.

[0048] pH
[0049] Natural eggs can have a pH range of about 6-8, although the pH of eggs can vary widely with freshness or other environmental factors. In some embodiments, the pH of the compositions provided herein can be similar to that of natural eggs. In some embodiments, the pH of the reconstituted compositions can be about 5.5-8.5, about 6-8, about 6.5-7.5, or about 7. In some embodiments, the pH of the compositions provided herein is different than natural eggs, e.g. more acidic or more basic than a natural egg composition. For example a composition provided herein can have, in some embodiments, a pH of less than 5.5, 5, 4.5, or less than 4. In other embodiments a composition provided herein can have a pH of greater than 6.5, 7, 7.5, or greater than 8. [0050] Binding Properties
[0051] Natural eggs provide binding properties that are useful in many cooking and non-cooking applications. Binding properties can refer to the properties of natural eggs that provide structural integrity to egg- containing or egg- substitute containing products, e.g., baked goods. Structural integrity of an egg- containing or egg-substitute containing product may be compared and/or indicated by, for example, whether the product falls apart during or after preparation, or by the quantity of fragments or crumbs that are generated when the product is handled. In some embodiments, the compositions provide binding properties of natural eggs. In some
embodiments, the compositions provide about 1-30%, about 20-50%, about 30-70%, about 40- 90%), about 60-100%) of the binding properties of a natural egg. In some embodiments, the compositions provide more than about 1%>, about 2%, about 3%, about 4%, about 5%, about 10%, about 15%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%), about 90%), about 100% of the binding properties of a natural egg. In some particular embodiments, the compositions provide more than about 50% of the binding properties of a natural egg. In some other particular embodiments, the compositions provide more than about 75%) of the binding properties of a natural egg. In yet other particular embodiments, the compositions provide more than about 90% of the binding properties of a natural egg. In some embodiments, the compositions may not provide binding properties.
[0052] Thickening agents
[0053] Eggs are commonly used as thickening agents for a number of food products, for example, sauces, custards, fillings, etc. Thickening can be caused by the physical interference of water molecules in the food product with molecules from the thickening product. Thickening properties of an egg-substitute product may be indicated by the ability to thicken the egg- substitute containing product to the desired amount in a smooth, consistent manner, while minimizing the formation of lumps. In some embodiments, the compositions can provide thickening properties. In some embodiments, the compositions can provide about 1-30%, about 20-50%, about 30-70%, about 40-90%, about 60-100% of the thickening properties of a natural egg. In some embodiments, the compositions provide more than about 1%, about 2%, about 3%, about 4%, about 5%, about 10%, about 15%, about 20%, about 30%, about 40%, about 50%, about 60%), about 70%, about 80%, about 90%, about 100% of the thickening properties of a natural egg. In some embodiments, the compositions provide more than about 50% of the thickening properties of a natural egg. In particular embodiments, the compositions provide more than about 75% of the thickening properties of a natural egg. In yet more particular embodiments, the compositions provide more than about 90% of the thickening properties of a natural egg. In some embodiments, the compositions may not provide thickening properties.
[0054] Leavening agents
[0055] Eggs provide leavening properties that are useful in a number of cooking and non- cooking applications. A leavening agent can have foaming action that introduces air bubbles into the product, and can be used to provide height, lightening, and fluffiness of the finished product. For example, eggs are commonly used in cake, bread, muffin, souffle, and other recipes to impart a fluffy texture to the final product. Leavening properties of an egg or egg- substitute may be indicated by the height and texture of the final product. For example, a light, airy texture indicates superior leavening compared to a heavy, gummy texture. In some embodiments, the compositions can provide leavening properties similar to that of natural eggs. In some embodiments, the compositions provide about 1-30%, about 20-50%, about 30-70%, about 40- 90%), about 60-100%) of the leavening properties of a natural egg. In some embodiments, the compositions provide more than about 1%, about 2%, about 3%, about 4%, about 5%, about 10%, about 15%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%), about 90%), about 100% of the leavening properties of a natural egg. In some
embodiments, the compositions provide more than about 50% of the leavening properties of a natural egg. In particular embodiments, the compositions provide more than about 75% of the leavening properties of a natural egg. In yet more particular embodiments, the compositions provide more than about 90% of the leavening properties of a natural egg. In some
embodiments, the compositions do not provide leavening properties.
[0056] Emulsifying properties
[0057] The emulsifying properties of natural eggs are useful in the preparation of food products which require the mixing and integration of substances that are immiscible, such as oil and water. Many products for human consumption are oil- in- water emulsions, including but not limited to hollandaise sauces and mayonnaise. In oil-in-water emulsions, oil droplets are dispersed evenly throughout an aqueous phase. However, oil droplets will tend to coalesce over time. An emulsifying agent can prevent the coalescence of the oil droplets, resulting in a smooth, creamy mixture. The emulsifying properties of the present compositions may be determined by the texture, consistency, and stability of the finished product, e.g., a sauce. For example, a sauce that remains smooth indicates a superior emulsion compared to a sauce that has undergone partial or complete separation over time. In some embodiments, the compositions can provide emulsifying properties. In some embodiments, the compositions provide about 1-30%, about 20-50%, about 30-70%), about 40-90%, about 60-100%) of the emulsifying properties of a natural egg. In some embodiments, the compositions provide more than about 1%>, about 2%, about 3%, about 4%, about 5%, about 10%, about 15%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%), about 80%>, about 90%>, about 100% of the emulsifying properties of a natural egg. In some embodiments, the compositions provide more than about 50% of the emulsifying properties of a natural egg. In particular embodiments, the compositions provide more than about 75%) of the emulsifying properties of a natural egg. In yet more particular embodiments, the compositions provide more than about 90% of the emulsifying properties of a natural egg. In some embodiments, the compositions do not provide emulsifying properties.
[0058] Texture
[0059] Eggs are commonly used to provide moisture and fat to a product recipe, resulting in a non-dry texture. The ability of an egg or egg substitute to provide the desired moisture and fat to a product recipe (such as, for example, cake or bread recipes) may be indicated by the texture of the finished product, e.g., whether the product produces a moist or dry crumb. In some embodiments, the compositions provide a moisture imparting quality. In some embodiments, the compositions provide about 1-30%, about 20-50%, about 30-70%, about 40-90%, about 60-100% of the desired moisture and fat of a natural egg. In some embodiments, the compositions provide more than about 1%>, about 2%, about 3%, about 4%, about 5%, about 10%, about 15%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, about 100%) of the desired moisture and fat of a natural egg. In some embodiments, the compositions provide more than about 50% of the desired moisture and fat of a natural egg. In particular embodiments, the compositions provide more than about 75% of the desired moisture and fat of a natural egg. In yet more particular embodiments, the compositions provide more than about 90% of the desired moisture and fat of a natural egg. In some embodiments, the compositions do not provide moisture and fat.
[0060] Color
[0061] Eggs can sometimes be used to provide a certain color to the food or non-food product. In some embodiments, the compositions can provide the same or similar color to the product. In other embodiments, the compositions do not provide similar color to that of natural eggs. In some embodiments, the compositions can be color neutral and may not affect the color of the product. [0062] Flavor
[0063] Eggs can be sometimes used to provide a certain eggy taste to the food product. Taste may be qualitatively assessed by blind taste test of the product prepared using the compositions compared to the product prepared using an equivalent amount of eggs. In some embodiments, the compositions can provide the same or a similar eggy taste to the product. In other embodiments, the compositions do not provide an eggy taste to the product. In some
embodiments, the compositions can be taste-neutral.
[0064] Egg Replacement
[0065] In some embodiments, the compositions can be used as a replacement for whole eggs, egg yolks, or egg whites in food products. In some embodiments, the food products can be baked goods such as but not limited to muffins, cakes, cupcakes, brownies, cookies, biscotti, pancakes, breads, waffles, pastries, pies, tarts, scones, pretzels, crackers. In some embodiments, the compositions can be used as a replacement for eggs or egg parts in other products such as but not limited to pasta, noodles, meatloaf, burgers, custards, sauces, ice cream, mayonnaise, and/or salad dressings.
[0066] In some embodiments, the compositions can be used as a replacement for whole eggs, egg yolks, or egg whites in non-food products, such as but not limited to shampoos, facial washes or masks, creams, films, encapsulates. In other embodiments, the compositions can be used for functions other than as an egg substitute.
[0067] Subjective Properties of the Compositions
[0068] Mouthfeel is a concept used in the testing and description of food products. Products made using the compositions of the invention can be assessed for mouthfeel. In some embodiments products, e.g baked goods, made using compositions of the invention have mouthfeel that is similar to products made with natural eggs. In some embodiments the mouthfeel of the compositions of the invention is superior to the mouthfeel of previously known or attempted egg substitutes, e.g bananas, modified way proteins, or Egg BeatersTM.
[0069] Examples of properties which may be included in a measure of mouthfeel include:
Cohesiveness: Degree to which the sample deforms before rupturing when biting with molars; Density: Compactness of cross section of the sample after biting completely through with the molars; Dryness: Degree to which the sample feels dry in the mouth; Fracturability: Force with which the sample crumbles, cracks or shatters. Fracturability encompasses crumbliness, crispiness, crunchiness and brittleness; Graininess: Degree to which a sample contains small grainy particles, may be seen as the opposite of smoothness; Gumminess: Energy required to disintegrate a semi- solid food to a state ready for swallowing; Hardness: Force required to deform the product to given distance, i.e., force to compress between molars, bite through with incisors, compress between tongue and palate; Heaviness: Weight of product perceived when first placed on tongue; Moisture absorption: Amount of saliva absorbed by product; Moisture release: Amount of wetness/juiciness released from sample; Mouthcoating: Type and degree of coating in the mouth after mastication (for example, fat/oil); Roughness: Degree of abrasiveness of product's surface perceived by the tongue; Slipperiness: Degree to which the product slides over the tongue; Smoothness: Absence of any particles, lumps, bumps, etc., in the product; Uniformity: Degree to which the sample is even throughout; homogeneity;
Uniformity of Bite: Evenness of force through bite; Uniformity of Chew: Degree to which the chewing characteristics of the product are even throughout mastication; Viscosity: Force required to draw a liquid from a spoon over the tongue; and Wetness: Amount of moisture perceived on product's surface.
[0070] Compositions
[0071] Protein
[0072] Natural eggs typically comprise about 5-15% protein content by weight. The high protein content of natural eggs play a central role in providing the desired binding properties of the eggs. In some embodiments, the compositions provided herein comprise proteins, polypeptides, and/or peptides, referred to collectively as "protein". In some embodiments, the compositions can comprise about 1%, about 2%, about 3%, about 4%, about 5%, about 7.5%, about 10%, about 15%), about 20%), about 25%, about 30% protein by dry weight or total weight. In some embodiments, the compositions can comprise about 1-5%, about 2-10%, about 5-20%, or about 10-30%) protein by dry weight or total weight. In particular embodiments, the compositions can comprise about 10-15% protein by dry weight or total weight.
[0073] In some embodiments, the proteins in the composition can comprise one or more plant- based proteins. In some embodiments, the one or more plant-based proteins may include, but are not limited to: pea proteins, isolates, and/or concentrates; garbanzo (chickpea) proteins, isolates, and/or concentrates; fava bean proteins, isolates, and/or concentrates; soy proteins, isolates, and/or concentrates; rice proteins, isolates, and/or concentrate; potato proteins, isolates, and/or concentrates; hemp proteins, isolates, and/or concentrates; or any combinations thereof. Plant- based proteins may include, for example, soy protein (e.g., all forms including concentrate and isolate), pea protein (e.g., all forms including concentrate and isolate), canola protein (e.g., all forms including concentrate and isolate), other plant proteins that commercially are wheat and fractionated wheat proteins, corn and it fractions including zein, rice, oat, potato, peanut, green pea powder, green bean powder, and any proteins derived from beans, lentils, and pulses. In other embodiments, the pea proteins can be derived from green peas or yellow peas. In particular embodiments, the pea proteins can be derived from yellow peas, such as Canadian yellow peas.
[0074] In some embodiments, proteins in the composition can comprise undenatured proteins. In other embodiments, proteins in the composition can comprise denatured proteins. In some embodiments essentially no animal proteins are used in the compositions.
[0075] Enzymes
[0076] Natural eggs contain a number of enzymes that are used in human products. For example, lysozyme, which may be extracted from egg whites, can be used in eye drop
formulations or as a cheese preservative. In some embodiments, the compositions comprise an enzyme profile similar to that of eggs. In some embodiments, the compositions comprise an enzyme profile dissimilar to that of natural eggs. In some embodiments, the compositions comprise lysozyme. In some embodiments, the compositions do not comprise lysozyme. In some embodiments the compositions provided herein contain enzymes that replicate the function of the natural egg enzymes. For example a natural egg enzyme may catalyze a particular known chemical reaction. Compounds of the invention can contain enzymes that catalyze the same or a similar reaction.
[0077] Oil/Fat
[0078] Natural chicken eggs typically comprise about 1 1% oil/fat content by weight. The fat content of natural eggs provides some of the desired moisture and texture to the egg- containing product, thus improving texture of the product. In some embodiments, the compositions can provide a similar fat profile to that of natural eggs. In other embodiments, the compositions can provide a lower fat profile to that of natural eggs while still imparting a desired moisture and texture to the product similar to an equivalent product prepared using natural eggs. In some embodiments, the compositions can comprise about 0.1%>, about 0.2%, about 0.5%>, about 1%, about 2%o, about 3%, about 4%, about 5%, about 7.5%, about 10%, about 15%, about 20%, about 25%), about 30%) fat by dry weight or total weight. In some embodiments, the compositions can comprise about 0.1-10%, about 0.5-15%, about 1-20%, or about 5-30% fat by total weight. In particular embodiments, the compositions can comprise about 1-10% fat by total weight. Natural eggs comprise about 3.1% saturated fats. The high saturated fat content of eggs may deter significant numbers of consumers from enjoying eggs or egg- containing products. In some embodiments, the compositions can comprise less than 3%, less than 2%, less than 1%, less than 0.5%), less than 0.1%>, or essentially no saturated fat. In some embodiments, the fat content of the compositions can comprise plant-based oils. In some embodiments, the plant-based oils can comprise canola oil, sunflower oil, safflower oil, coconut oil, corn oil, olive oil, peanut oil, or palm oil. In some embodiments, the plant-based oils can comprise oils from beans (e.g garbanzo beans or fava beans).
[0079] In some embodiments, the compositions are esssentially free of fat and/or oil, such as animal fats or animal oils. In some embodiments, the compositions do not comprise fat. In some embodiments, the compositions do not comprise oil. In some embodiments the compositions do not comprise any animal oils or fats. In some embodiments the compositions comprise less than 3%), less than 2%, less than 1%>, less than 0.5%>, or less than 0.1%> plant fats or oils. In some embodiments the compositions comprise less than comprise less than 3%, less than 2%, less than 1%), less than 0.5%>, or less than 0.1%> animal fats or oils.
[0080] Nutrients
[0081] Eggs are also highly valued for their vitamin and nutrient content. In particular, eggs are a natural source of vitamins A, E, D, and other vitamins and nutrients, providing about 540 IU vitamin A, 1.050 mg vitamin E, and 47 IU vitamin D per 100 g total weight. In some embodiments, the compositions provide a vitamin profile similar to that of eggs by equivalent weight. In some embodiments, the compositions can be fortified with vitamins to provide a high nutritional value per unit weight compared to natural eggs. In some embodiments, the compositions do not provide a vitamin profile similar to eggs. In some embodiments the nutritional profile of the compositions of the invention is superior to natural eggs.
[0082] In addition, eggs are a source of choline, a nutrient that supports healthy brain
development. In some embodiments, the compositions provide similar amounts of choline as compared to an equivalent weight of eggs. In some embodiments, the compositions may be fortified with choline to provide a higher nutritional value per unit weight compared to natural eggs. In some embodiments, the compositions do not provide similar amounts of choline as an equivalent weight of natural eggs.
[0083] Nucleic Acids [0084] Eggs will contain nucleic acids from the species that laid the egg. So a bird egg will contain DNA from a bird and a reptile egg will contain DNA from a reptile. As the compositions of the invention are not derived from these species the compositions of the invention will not normally contain DNA normally associated with an egg. Therefore in some embodiments the compositions of the invention contain no nucleic acids from a bird, a reptile, an amphibian, or a fish. It is possible that for a variety of reasons one would wish to add the egg related nucleic acids to the compositions described herein. This would result in a product that contained an artificially added nucleic acid. In some embodiments the compositions of the invention contain no artificially added nucleic acids typically associated with an egg.
[0085] Flours
[0086] In some embodiments, the composition can comprise one or more flours. In some cases, flour is a powder ground from grains, seeds, roots, or other sources. Most flours have a high starch content which imparts thickening and binding properties, and may provide moisture content. In some embodiments, the one or more flours are selected from all-purpose flour, unbleached flour, bleached flour, bread flour, self-rising flour, wheat flour, cake flour, acorn flour, almond flour, amaranth flour, atta flour, rice flour, buckwheat flour, cassava flour, chestnut flour, chuno flour, coconut flour, corn (maize) flour, hemp flour, maida flour, mesquite flour, nut flour, peanut flour, potato flour, rice flour, rye flour, tapioca flour, t'eff flour, soy flour, peanut flour, arrowroot flour, taro flour, acorn flour, bean flours such as, e.g., soy flour, garbanzo flour, fava bean flour, pea flour; or other flour. In some embodiments, the one or more flours are selected from Sorghum, White sorghum, Soy bean, Millet, Vallarta, Stueben, Green fagelot, Black beluga, Black calypso, Chana daL Amaranth, Lentil, Red lentil, Black lentiL Golden lentiL Do pung- style lentiL Sprouted green lentil, Sweet brown rice, Navy bean, Red bean, Pink bean, Canellini bean, Giant white lima bean, Christmas lime bean, Baby lima bean, Mung bean, Peeled fava bean, Good mother stellard bean, Cranberry chorlottis bean,Santa maria pinguinto bean, Brown tepary bean, Black turtle bean, Yellow slit pea, Canadian yellow pea, Black turtle beans, Brown teff flour,Rye flour, Quinoa flour, Potato flour, White rice flour, Brown rice flour, Oat flour, Buckwheat flour, Whole grain corn flour, Stone ground cornmeaL Pre-cooked split pea, Pre-cooked garbanzo flour, Arrowroot powder, and Potato starch. In some embodiments, the composition can comprise about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 85% about 90%, about 95%, about 100% flour. In some embodiments, the composition can comprise about 1-30%, about 10-40%, about 30-70%, about 50-99%, about 60-95%, about 70-90% total flour by dry weight. In some embodiments, the flour is cold-milled.
[0087] Flours can differ widely in their protein content, containing as low as 5% to as high as 30%) protein. Natural chicken eggs typically comprise about 10-15% protein content by weight. The high protein content of natural eggs play a central role in providing the desired binding properties of the eggs. Furthermore, flours can differ widely in their fat content, containing as low as 0.1%) to as high as 15% fat content.

[00115] Methods of Making and Storing the Compositions
[00116] In some embodiments, the compositions can be prepared by dry blending. In some embodiments, the compositions can be processed using an inline high-shear mixer, cell disruption, liquid chromatography, including HPLC, sonication, and/or rotor-stator mixing technology. In some embodiments, the mixer can have a pump capability of at least about 500 gallons/minute, with a throughput of 50 gallons/minute. In some embodiments, the sonicator can have a throughput of at or above 5 gallons/minute. In other embodiments, the compositions can be prepared using standard home kitchen materials, e.g., a kitchen scale, mixing bowL utensils, blender, or food processor. In some embodiments, the compositions can be stored as a dry material.
[00117] Storage and shelf life
[00118] Eggs and products made from eggs have a limited shelf-life. Raw eggs in the shells should only be stored with refrigeration for up to 5 weeks. When the yolk or the white are removed from the shell the storage life with refrigeration drops to only a maximum of 4 days. Commercially available non- sterile liquid egg substitutes also have a limited shelf life of up to about 7 days in the refrigerator. Similarly foods cooked with eggs have a limited storage life. A pie or a quiche cooked with eggs should only be stored for less than a week with refrigeration. Compositions of the invention can provide significant gains in shelf- life, for both the egg substitute and for products produced using the egg substitute.
[00119] Compositions of the invention can, in some embodiments, be stable in storage at room temperature for up to 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 weeks. In some embodiments compositions of the invention are stable for storage at room temperature for months, e.g. greater than 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, or 13 months. In some embodiments compositions of the invention are stable for refrigerated or freezer storage for months, e.g. greater than 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, or 13 months. In some embodiments compositions of the invention are stable for refrigerated or freezer storage for years, e.g. greater than 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, or 13 years. In some embodiments products produced using compositions of the invention are stable for storage at room temperature for months, e.g. greater than 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, or 13 months. In some embodiments products produced using compositions of the invention are stable for storage at room temperature for years, e.g. greater than 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, or 13 years.
[00120] In some embodiments, storage as a dry material can increase the shelf-life of the composition. In some embodiments the compositions are stored as a dry material for later reconstitution with a liquid, e.g. water.
[00121] Reconstituting from a Dry Composition
[00122] In some embodiments the compositions in the invention are reconstituted with a liquid, e.g. water, milk, or other liquid suitable for human consumption. In one example 36-45 grams of liquid can be added to 12-15 grams dry weight of the composition to produce a substitute for 1 whole egg. The amount of liquid can be varied to suit a particular purpose for the reconstituted composition.
[00123] In some embodiments, the compositions, prior to the addition of water, could be first subjected to a sonicator, and the water content then added via a higher throughput method such as the inline high- shear mixer or rotor- stator mixer. Ability to apply intense shear and shorten mixing cycles can be desirable in creating desirable emulsions, or agglomerated powders — to be dispersed into a liquid medium. In some embodiments, the inline mixer is positioned in a flowing stream, the mixing process can be more tightly controlled than in a batch configuration, ensuring that the number of passes through the high-shear zone can be monitored with greater confidence. In some embodiments, solid and liquid additions can also be injected into the flow and dispersed with reproducible results.
[00124] Pre-hydrating the protein (e.g. incubating the flour with water for 24 hours) can in some embodiments improve the properties of the composition. Accordingly, in some
embodiments a dry composition is prehydrated for several hours or days, e.g. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 hours or 1,2, or 3 days. In one embodiment prehydrating the composition gives a thicker and stronger emulsion when the composition is used in food preparation.
[00125] Heating
[00126] Heat can be used to prepare the compositions of the invention. Heat can aid in reconstituting the compositions in a liquid. Heat can also serve to denature proteins of the compositions. However, in some embodiments heat is not necessary for preparing the compositions. Therefore in some embodiment the compositions of the invention are prepared by heating one or more components of the composition to a temperature of at least 60, 70, 80, 90, or 100 degrees Celsius. In some embodiments the components of the composition are heated to a temperature range of about between 60 and 80 or 85 degrees Celsius. In some embodiments the range is about between 59 and 81 or 86 degrees Celsius. In some embodiments the components of the composition are heated to less than 60 degrees Celsius or to more than 85 degrees Celsius. In some embodiments the heated composition is held at the elevated temperature for 1 - 10 minutes for 10 - 20 minutes. In some embodiments the heated compositions are held at the elevated temperature for less than 1 minute. In some embodiments the components of the composition are not heated for preparation of the composition.
[00127] Food Products
[00128] In some aspects, the invention provides a food product prepared using the compositions described herein, wherein the food product is indistinguishable from an equivalent product prepared using eggs. In some cases, the food product is a baked food product. Such baked food products include cookies, brownies, cake, and the like. In some cases, the food product is a sauce, dressing, or custard. In some cases, the food product is a scramble, omelet, or quiche indistinguishable from a scramble, omelet, or quiche prepared using eggs. In some cases, the food product is an ice cream, pasta, meatloaf, or burger patty. In some embodiments the food product is an emulsion, such as mayonnaise or dressings.

[00147] Example 7
[00148] Replacing eggs in mayonnaise
[00149] Eggs in standard full-fat mayonnaises (e.g a 78% full- fat mayonnaise) can be replaced by a blend of 50%> pea protein isolate and 50%> modified starch. The pea protein contains 80%> protein, a maximum of 10%> carbohydrate, a maximum of 3% fat, and maximum of 1%) fiber. The modified starch is a cold-water soluble modified starch derived from waxy maize. See Figure 12.
[00150] Example 8
[00151] Replacing eggs in mayonnaise
[00152] Eggs in standard full-fat mayonnaises (e.g a 78% full- fat mayonnaise) can be replaced by a blend of 59% pea protein isolate and 41%> modified starch. The pea protein contains 80%> protein, a maximum of 10%> carbohydrate, a maximum of 3% fat, and maximum of 1%) fiber. The modified starch is a cold-water soluble modified starch derived from waxy maize. See Figure 12.
[00153] Example 9
[00154] Food products equivalent to full- fat mayonnaise [00155] Compositions of the inventions are useful for the production of food products that are substantially identical to food products produced with real eggs. For example the
compositions disclosed in Example 7 and 8 produce a product which is substantially similar to standard 78% full- fat mayonnaises. This will result in a product containing no egg or egg byproducts that when rated by a human is substantially the same as a standard full- fat mayonnaise.
[00156] In this example, pre-hydrating the protein (incubating the flour with water for 24 hours) gives a much thicker and stronger emulsion.
[00157] Example 10
[00158] Extraction of pea protein from an off-the-shelf pea protein product results in better results compared to use of the off-the-shelf pea protein product.
[00159] Example 11
[00160] A few dozen iterations of making mayonnaise with pea protein and starch (as above) in combination with a wide range of commercial gums and starches resulted in different product structures. Emulsion stability was highest using the pea protein/starch combination of Example 7 and Example 8.
[00161] These gums and starches include: guar gum, xanthan gum,
carboxymethylcelluloses and other maize starches in varying concentrations.
[00162] Example 12
[00163] Addition of gums and cellulose makes the structure of the egg substitute more creamy and smooth, but the stability of the emulsion may be less than without.
[00164] A typical formulation for a creamy egg substitute for an emulsion is:
46% pea protein isolate
46%) modified starch
4%) mix of guar gum and xanthan gum
4%) carboxymethylcellulose
[00165] Example 13
[00166] Replacing eggs in bakery products: cookies
[00167] An egg-replacer for cookies is:
74%) cold milled sorghum flour
17%) baking soda 8.3% micronized corn bran
0.6 % xanthan gum
[00168] A second egg-re lacer formulation in a range of cookies (chocolate chip, oatmeal raisin, peanut butter and snickerdoodle):
86% garbanzo(chickpea) flour
10%) micronized corn bran
3.2%) baking powder
0.8%) xanthan gum
[00169] Example 14
[00170] Cold milling methodology
[00171] Seeds milled in the presence of liquid nitrogen preserve protein conformation allowing them to remain more functional in the application. A typical formulation is cold milling of seeds to form flour that is used as a replacement for flour from seeds milled at ambient or elevated temperatures in any of the above uses or recipes.
[00172] Example 15
[00173] Replacing eggs in bakery products: cakes and muffins
[00174] Both cold- and ambient-milled extracts from the following seeds are tested for leavening, cohesiveness and springiness in muffins: Sorghum, White sorghum, Soy bean, Millet, Vallarta, Stueben, Green fagelot, Black beluga, Black calypso, Chana daL Amaranth, Lentil, Red lentiL Black lentiL Golden lentil, Do pung-style lentil, Sprouted green lentil, Sweet brown rice, Navy bean, Red bean, Pink bean, Canellini bean, Giant white lima bean, Christmas lime bean, Baby lima bean, Mung bean, Peeled fava bean, Good mother stellard bean, Cranberry chorlottis bean,Santa maria pinguinto bean, Brown tepary bean, Black turtle bean, Yellow split pea, Black turtle beans, Brown teff flour, Rye flour, Quinoa flour, Potato flour, White rice flour, Brown rice flour, Oat flour, Buckwheat flour, Whole grain corn flour, Stone ground cornmeal, Pre-cooked split pea, Pre-cooked garbanzo flour, Arrowroot powder, and Potato starch.
[00175] Example 16
[00176] Muffins
[00177] Following a standard recipe for muffins, 11 different types of muffins were made. Each batter was made at half recipe. The equivalent of a whole egg was mixed for each substitute, but only half the formulation was used in the recipe consistent with the half recipe batter volume.

[00182] Example 18
Cryo-milled and ambient-milled extracts from the same type of grain or legume are showing different functional effects when used in baking standard recipe muffins. These functional effects comprise important parameters in baked goods such as cohesiveness, springiness, leavening, airiness.
[00183] Example 19
[00184] Extraction methodology
[00185] Flours are incubated with water to extract the soluble fraction, which is separated from the pellet by centrifugation after which the supernatant is used in the application.
[00186] Example 20
[00187] Pre-hydrating the protein
[00188] Incubating flour with water gave a thicker and stronger emulsion when the composition is used in food preparation. Egg-rep lacer was incubated with water for 1, 3 or 5 hours before using it to prepare an egg-less mayonnaise. The resulting mayonnaise was tested in a Bostwick consistometer. The thickness of the mayonnaise as reflected in a smaller distance travelled increased with hydration time. Results are shown in Figure 11.
[00189] Example 20
[00190] Fractionating protein
[00191] Fractionating protein and adding the light fraction of flours to baked goods results in a better texture compared to adding the corresponding whole flours. Especially the
cohesiveness of the baked goods is stronger when prepared with the light fraction. The light fraction can be obtained by methods like centrifuging or air classification. [00192] Example 21
[00193] Mayonnaise
[00194] Mayonnaises made with eggs or with a pea protein- starch composition were made and compared at room temperature with a commercial egg-mayonnaise after dilution with 20 vol% water in a Bostwick consistometer. Fresh-made egg mayonnaise and commercial egg mayonnaise have similar consistencies, which is a validation of the mayonnaise production process. The eggless mayonnaise had a thicker consistency than both the commercial and fresh- made egg mayonnaise. See Figure 13.
