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, soufflés, muffins, scones, biscuits, pasta, dressings, sauces, and ice cream.
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.
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™, EnerG™ 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.
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.
In some embodiments, the compositions may be used to replace egg yolks. In other embodiments, the compositions may be used to replace egg whites.

Thickening Agents
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 may not provide thickening properties.
Leavening Agents
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, soufflé, 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.
Emulsifying Properties
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.
Texture
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.
Color

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%, 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).
In some embodiments, the compositions are essentially 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.
Nutrients
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.
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.
Nucleic Acids
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.
Flours
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, chuño 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 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.
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. The fat content of natural eggs provides some of the desired moisture and fat to the egg-containing product, thus improving texture of the product. However, the high saturated fat content of eggs may deter significant numbers of consumers from enjoying the product.
Therefore, in some embodiments, the one or more flours are selected from flours with high protein content and a fat content similar to that of natural eggs, wherein the fat content is provided essentially by unsaturated fats. In some embodiments, the one or more flours may comprise garbanzo/chickpea flour, fava bean flour, soy flour, nut flours. A significant number of potential consumers may have nut allergies, therefore, in particular embodiments, the one or more flours comprise garbanzo and/or fava bean flours. In some embodiments, the composition may 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% garbanzo flour.

Methods of Making and Storing the Compositions
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.
Storage and Shelf Life
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.
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.
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.
Reconstituting from a Dry Composition
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.
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.
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.
Heating
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.

The compositions of Examples 1-2 and other compositions disclosed herein are used to replace eggs in traditional recipes, e.g. in baked goods, such as cakes, muffins, pastries, or cookies. The resulting foods, in this case baked goods, have superior qualities as compared to products baked with other egg substitutes. For example the mouthfeel of a yellow cake baked using the compositions of Examples 1-2 is more similar to yellow cake baked with eggs than yellow cake baked using previously attempted egg substitutes.
Mouthfeel ratings will demonstrate these similarities.
In another example the taste of a cookie baked using the compositions of Examples 1-2 and further compositions described herein will be more similar a cookie baked using eggs than previously attempted egg substitutes.
Taste ratings will demonstrate these similarities.
Foods prepared using the compositions provided herein will be shown to have substantially identical properties as foods prepared using natural eggs. A composition provided herein will allow the preparation of egg-free foods with substantially identical viscosity, binding properties, thickening properties, leavening properties, emulsifying properties, texture, color, and/or flavor.
As seen in the following table and
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
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
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 by-products that when rated by a human is substantially the same as a standard full-fat mayonnaise.
In this example, pre-hydrating the protein (incubating the flour with water for 24 hours) gives a much thicker and stronger emulsion.
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.
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.
These gums and starches include: guar gum, xanthan gum, carboxymethylcelluloses and other maize starches in varying concentrations.
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.
A typical formulation for a creamy egg substitute for an emulsion is:
An egg-replacer for cookies is:
74% cold milled sorghum flour
17% baking soda
8.3% micronized corn bran
0.6% xanthan gum
A second egg-replacer 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
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.
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.
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.
Following a standard recipe for muffins, 6 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.
Results are shown in
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.
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.
Incubating flour with water gave a thicker and stronger emulsion when the composition is used in food preparation. Egg-replacer 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
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.
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
Particle size distribution of a control egg-mayonnaise (Con/dark line) and an eggless mayonnaise (Test/light line) made with pea protein and starch. Both mayonnaises were tested in a Malvern Mastersizer 3000 light-scattering device. The oil droplet size distribution of the eggless mayonnaise is similar to that of the control mayonnaise, demonstrating that using the egg-replacer resulted in a mayonnaise with the same oil droplet distribution as a control egg-mayonnaise.

Muffins were prepared to test height, cohesiveness, and springiness.
For cryo-milling, beans/grains were placed in liquid nitrogen until thermal equilibrium was reached. Cryogenized beans/grains were milled in a heavy duty blender until the flour temperature reached a temperature of 20° C.
For ambient milling, beans/grains were processed in a heavy duty blender until the flour temperature reached a temperature 90° C. after which they were kept at that temperature for 5 min.
Flours were collected from the blender and were tested in a standard recipe muffin. Cohesiveness and springiness were measured using a Brookfield Texture Analyzer. Height of the muffin was measured using a digital caliper. WL represents giant white lima beans. GM represents good mother stallard beans. BL represents black lentils. OB represents baby lima beans.
