Patent Application
20210289804
The present disclosure relates to food products that are derived substantially from or wholly from non-animal sources, for example, non-dairy analogs and method of using such products. Certain embodiments are directed to non-dairy analogs where at least a portion of the protein used in the non-dairy analog is a succinylated refined protein that which results in improved stability and solubility of the non-dairy analog, for example reducing feathering when added to beverages such as coffee or tea. These non-dairy analogs may also be used as a substitute for dairy products in a wide range of food products, including for example, yogurt, sour cream, creamers, and cheeses.
Consumers often add dairy products such as creamers to beverages such as coffee or tea. Dairy creamers are often made with dairy milk and/or dairy cream. Dairy creamers are desired by many consumers because of the milky flavor and creamy texture they add to the beverage. In addition, these dairy creamers tend to mix well with the beverage. Dairy creamers, and other dairy-based products, however have many qualities that consumers find disadvantageous, including but not limited to, the presence of saturated fat, the amount of fat, the presence of cholesterol, and/or the presence of lactose. For example, many people would prefer a non-dairy alternative to dairy creamers because of the high fat and calorie levels. In addition, many people are not able tolerate such products due to lactose intolerance and/or prefer not to consume animal-based products.
There are known non-dairy analogs, for example some non-dairy analogs are made with sodium caseinate or whey proteins. Other known non-dairy analogs are made with a soy protein. However, these alternative non-dairy analogs suffer from several drawbacks, such as a thin and chalky mouth feel, a green or beany flavor, undesirable color and so forth. In particular, one set of problems with existing non-dairy analogs is relative lack of stability and/or solubility when added to a beverage such as coffee. When adding dairy milk or dairy creamer to coffee it typically dissolves well, remains stable within the solution, and provides a whitening or creamy look. A problem with existing non-dairy analogs is that they exhibit feathering when added to a beverage such as coffee or tea. Feathering is typically described as the presence of particles due to coagulation or precipitation of proteins within the beverage. Feathering imparts an undesirable visual experience and/or an undesirable mouthfeel experience for the consumer of the beverage in which it occurs. Proteins are typically a substantial component of non-dairy analogs and/or non-dairy milk products and their lack of stability, and/or lack of solubility are believed to play a role in feathering in these beverages.
To reduce feathering in non-dairy analogs it has been proposed to include inorganic salts in such products. For example, it has been proposed to include di-potassium hydrogen phosphate, sodium aluminum phosphate, and polyphosphates. However, the use of such inorganic salts has a negative impact on the taste, health and/or nutritional aspects of such non-dairy analogs. Therefore, there exists an unmet need for non-dairy milk and/or non-dairy analogs for use in food beverages such as coffee or tea that are stable, soluble, and/or do not feather or have a substantial reduction in feathering. The present disclosure provides such and related food products, methods of making such products and methods of using such products. The present disclosure is directed to solving these and other problems disclosed herein. The present disclosure is also directed to overcome and/or ameliorate at least one of the disadvantages of the prior art as will become apparent from the discussion herein. The present disclosure is also directed to addressing one or more advantages to using the products and/or methods disclosed herein.

Beverage Formulations Containing Succinylated Refined Protein
As described above, non-dairy analogs containing a succinylated refined protein component exhibit improved qualities of improved solubility and decreased visible precipitation of the protein component when mixed in an aqueous beverage such as coffee or tea. These improved qualities also extend to the use of a succinylated refined protein component in other protein-containing beverage formulations. A wide range of beverage formulations incorporate a significant portion of a refined protein component in an aqueous mixture. Such protein-supplemented beverage formulations include but are not limited to, protein drinks, post-work-out drinks, vitamin drinks, exercise drinks, electrolyte drinks, fruit juice drinks, and iced tea drinks. It is contemplated that the beverage formulations comprising a succinylated refined protein component can be used for any aqueous beverage that is supplemented with a plant protein. Generally, it is highly desirable to minimize any precipitation of a refined protein component in such beverages because consumers generally prefer a substantially transparent beverage without gritty or chalky solids present.
Accordingly, in some embodiments, the present disclosure provides a beverage formulation, wherein the formulation comprises: (a) a refined protein component in which at least a portion of the refined protein component is a succinylated refined protein component; (b) water or carbonated water; and (c) a pH of between 6 and 9.
In some embodiments of the beverage formulation, the refined protein component is sourced from a plant; optionally, sourced from a legume. In some embodiments, the refined protein component is sourced from a pea plant or a pea protein. Generally, the wide range of plant proteins described elsewhere herein as useful with non-dairy analogs can also be used as a refined protein component in the beverage formulations of the present disclosure.
In some embodiments the beverage formulation can comprise additional ingredients selected from: (a) sugar and/or a carbohydrate; (b) at least one vitamin or mineral; (c) at least one lipid from a non-animal natural source; and/or (d) at least one emulsifier, and/or a hydrocolloid or gum. Generally, the ingredients described elsewhere herein as useful with non-dairy analogs (e.g., carbohydrates, emulsifiers, lipids, etc.) can be used as ingredients in the beverage formulations of the present disclosure.
As described elsewhere herein for non-dairy analogs, it is an advantage of the beverage formulations of the present disclosure that the succinylation of a portion of the refined protein component (e.g., using 0.2 g succinic anhydride per g protein) greatly improves the protein solubility and precipitation related qualities of the beverage. In some embodiments the improved protein solubility qualities of the beverage formulation: (a) exhibits less than 5%, 3%, 1% or 0.5% by weight precipitation of the refined protein component; and/or (b) exhibits less than 5%, 3%, 1% or 0.5% by volume precipitation of the refined protein component.
These improved protein solubility qualities of the beverage formulations of the present disclosure are increasingly important in beverage formulation comprising substantial amount of protein. In some embodiments of the beverage formulations it is contemplated that the refined protein component comprises is at least 1%, 2%, 3%, 5%, 8% or 10% by weight of the beverage formulation.
As described with respect non-dairy analogs, the amount of succinylated refined protein used in a beverage formulation can be varied depending on the particular beverage application. For example, a high-protein post-workout beverage formulation may require a higher level of succinylated refined protein component in order to keep overall protein solubility desire levels. Accordingly, in some embodiments of the beverage formulation, the succinylated refined protein component is at least 30%, 40%, 50%, 60%, 70%, 80%, 90% or 100% by weight of the total weight of the refined protein component.

The water or aqueous component may be an aqueous liquid, including but not limited to pure water, tap water, bottled water, deionized water, spring water, or a mixture thereof. The aqueous component may also contain suitable dissolved materials.
The lipid, protein, and aqueous components may be mixed in various orders. In some embodiments, the three components are mixed simultaneously. In other embodiments, the lipid is mixed with the protein component before the aqueous component is introduced into the mixture. In yet other embodiments, the protein component is mixed with the aqueous component before the lipid is introduced into the mixture. In yet other embodiments, the lipid is mixed with the aqueous component before the protein component is introduced into the mixture.
Combining the lipid, protein, and aqueous components may be accomplished using a variety of mixing devices, for example, mechanical agitators and/or pressure jets. The components may also be stirred or mixed by hand. Mixing may continue until the components are distributed substantially evenly throughout the mixture.
In some embodiments, a carbohydrate component may be also added. A variety of ingredients may be used as the carbohydrate component, including but not limited to starch, simple sugars, flour, edible fiber, and combinations thereof. Examples of suitable starches include but are not limited to maltodextrin, inulin, fructo oligosaccharides, pectin, carboxymethyl cellulose, guar gum, corn starch, oat starch, potato starch, rice starch, wheat starch, or combinations thereof.

In other embodiments, the one or more other ingredients are added to the lipid and/or protein components or to the lipid, protein, and aqueous mixture. In some embodiments, the one or more other ingredients include calcium.
Emulsification may occur without additional mechanical energy, or require mechanical energy (for example, vortexing, homogenization, agitation, sonication, or other suitable mechanical activity). When emulsification is aided by lower amounts of mechanical energy (for example, agitation in a conventional mixer under moderate shear of between about 100 rpm and about 1,000 rpm), the average droplet size of the resulting emulsion is typically larger (for example, at least about 75% of the droplets have a diameter greater than about 25 um). When emulsification is aided by higher amounts of mechanical energy (e.g., homogenization in a high-pressure [for example, between about 35 bar and about 650 bar] 1- or 2-stage homogenizer [e.g., between about 1,000 rpm and about 10,000 rpm], or microfluidic homogenization [between about 500 and about 2,000 bar], the average droplet size of the resulting emulsion is typically smaller (for example, at least about 75% of the droplets have a diameter of less than about 10 um). Nanoemulsions may be obtained by homogenizing in a microfluidizer or other suitable equipment. In certain applications, to obtain higher lipid emulsions, the lipid component may be added gradually during mixing. Heating may aid in emulsification in certain applications. In some embodiments, emulsification is performed at greater than room temperature, greater than 30° C., 40° C., 50° C., 60° C., 70° C., or 80° C., between 90° C. and 120° C., between 30° C. and 60° C., or between 40° C. and 50° C. Heating is generally followed by cooling. Emulsification may be monitored by removing a sample of the mixture and analyzing it by such methods as microscopy, light scattering, and/or refractometry.
The emulsions may have droplets of various sizes. In some embodiments, the emulsions are polydisperse emulsions (i.e., emulsions comprising droplets with a broad distribution of droplet sizes). In other embodiments, the emulsions are monodisperse (i.e., emulsions comprising droplets with a narrow distribution of droplet sizes). In some embodiments, the emulsions are microemulsions (i.e., thermodynamic stable systems of dispersed droplets in continuous phase). In other embodiments, the emulsions are nanoemulsions (i.e., metastable [or kinetically stable] dispersions of one liquid in different immiscible liquid having droplet sizes ranging from 1 to 100 nm). In some embodiments, the emulsions have an average droplet size of less than about 1,000 nm, less than about 750 nm, less than about 500 nm, less than about 250 nm, less than about 100 nm, or less than about 50 nm, between about 100 nm and about 800 nm, or between about 100 nm and about 300 nm. In some embodiments, droplet sizes are reduced in order to reduce the lipid contents of the emulsions and non-dairy analogs provided herein. The degree of emulsification achieved and hence the final textures of the emulsions may be controlled to a certain degree by varying certain parameters during emulsification. Examples of such parameters include, but are not limited to, the type and/or amount of lipid component, the type and/or amount of protein component, the type and/or amount of optional emulsifiers, the amount of mechanical energy used during emulsification, the centrifugation or filtration techniques, the pH of the aqueous component, the temperature during mixing, the amount of optional salt in the aqueous component or combinations thereof.
In some embodiments, the non-dairy analog may be sterilized or pasteurized. Sterilization may occur by UV irradiation, heating (e.g. steam sterilization, flaming, or dry heating), or chemical sterilization (e.g., exposure to ozone). In some embodiments, sterilization kills more than 95% of microbes. For pasteurization, the non-dairy analog may be heated to a temperature (e.g., between about 280 and about 306° F.) and held at such temperature for a period of time (e.g., between about 1 and about 10 seconds). Appropriate pasteurization steps are known in the art of food manufacturing and may be undertaken at a variety of temperatures and/or for a variety of time durations. Pasteurization may be high-temperature, short-time (HTST), “extended shelf life” (ESL) treatment, high pressure pasteurization (HPP), ultra pasteurization (UP), ultra-high temperature (UHT) or combinations thereof. A controlled chilling system may be used to rapidly cool the non-dairy analog. In some embodiments, the non-dairy analogs undergo vacuum cooling to remove volatiles and water vapor following pasteurization.
The non-dairy analog may optionally be dried to obtain powders. Drying may be performed in a suitable way, including but not limited to spray drying, dry mixing, agglomerating, freeze drying, microwave drying, drying with ethanol, evaporation, refractory window dehydration or combinations thereof.

Methods for Obtaining Refined Protein Components
Certain embodiments are directed to methods for obtaining refined protein components from non-animal natural sources. Some of the advantages of the methods provided herein are that they may remove, or substantially remove, flavoring agents, aroma agents, coloring agents, other agents or combinations thereof from refined protein preparations, and thus make the refined protein preparations more suitable for use in non-dairy analog. Removal of such agents may also increase the shelf life of non-dairy analogs comprising such refined protein components.
The methods provided herein for obtaining refined protein components from non-animal natural sources may comprise one or more of the following steps, in or out of order:
a. obtaining a protein preparation from a non-animal natural source;
b. washing the protein preparation at a wash pH;
c. extracting the protein preparation at an extraction pH to obtain an aqueous protein solution;
d. separating the aqueous protein solution from non-aqueous components;
e. adding salt;
f. precipitating the protein from the aqueous protein solution at a precipitation pH to obtain a protein precipitate;
g. separating the protein precipitate from non-precipitated components; and
h. washing the protein precipitate to obtain a refined protein component.
The refined protein preparation obtained from a natural source may have various forms, including, but not limited to, protein concentrate, protein isolate, flour, protein meal; native, denatured, or renatured protein; dried, spray dried, or not dried protein; enzymatically treated or untreated protein; and combinations thereof. It may consist of particles of one or more sizes, and may be pure or mixed with other components (e.g., other plant source components). The refined protein preparation may be derived from non-animal natural sources, or from multiple natural sources. In some embodiments, the refined protein preparation is obtained from a plant. In some such embodiments, the plant is legume. In some such embodiments, the legume is pea. The pea may be whole pea or a component of pea, standard pea (i.e., non-genetically modified pea), commoditized pea, genetically modified pea, or combinations thereof. In some embodiments, the pea is Pisum sativum. In some embodiments, the legume is soy. The soy may be whole soy or a component of soy, standard soy (i.e., non-genetically modified soy), commoditized soy, genetically modified soy, or combinations thereof. In some embodiments, the legume is chickpea. The chickpea may be whole chickpea or a component of chickpea, standard chickpea (i.e., non-genetically modified chickpea), commoditized chickpea, genetically modified chickpea, or combinations thereof. In some embodiments, the refined protein preparation may be pre-treated for various purposes, such as, for example, extracting the protein preparation in a solvent to remove lipids, and heat treating the protein preparation to remove volatiles.
Washing the refined protein preparation may utilize various methods, including single wash, multiple washes, and/or counter-current washes.
The wash and extraction pH may be a pH that is suitable for washing and solubilizing proteins in a protein preparation. A suitable wash and extraction pH may be determined by testing various pH conditions, and identifying the pH condition at which the most optimal yield and quality (judged by, for example by one or more of the following: flavor, odor, color, nitrogen content, Ca content, heavy metal content, emulsification activity, MW distribution, and thermal properties of the protein component obtained) of the refined protein component is obtained. In some embodiments, the wash and extraction pH are alkaline pH. In some such embodiments, the alkaline pH is at least 7.1, at least 8, at least 9, at least 10, at least 11, at least 12, between 7.1 and 10, between 8 and 10, between 9 and 10, or between 8 and 9. In some such embodiments, the alkaline pH is 8.5. In some embodiments, the wash and extraction pH are acidic pH. In some such embodiments, the acidic pH is less than 7, less than 6.95, less than 6.5, less than 5, less than 4, less than 3, between 2 and 6.95, between 3 and 6, or between 3 and 5. The extraction pH may be adjusted using a pH adjusting agent. In some embodiments, the pH adjusting agent is a food grade basic pH adjusting agent. In other embodiments, the pH adjusting agent is a food grade acidic pH adjusting agents. Examples of suitable acidic pH adjusting agents include, but are not limited to, phosphoric acid, acetic acid, hydrochloric acid, citric acid, succinic acid, and combinations thereof. Examples of suitable basic pH adjusting agents include, but are not limited to, potassium bicarbonate, sodium bicarbonate, sodium hydroxide, potassium hydroxide, calcium hydroxide, ethanolamine, calcium bicarbonate, calcium hydroxide, ferrous hydroxide, lime, calcium carbonate, trisodium phosphate, and combinations thereof. It is useful to obtain substantially as much extracted protein as is practicable so as to provide an overall high product yield. The yield of protein in the aqueous protein solution may vary widely, wherein typical yields range from 1% to 90%. The aqueous protein solution typically has a protein concentration of between 1 g/L and 300 g/L. The molecular weight distribution of the proteins comprised in the aqueous protein solution may vary widely.
Separating the aqueous protein solution from non-aqueous components may be accomplished by various methods, including but not limited to, centrifugation followed by decanting of the supernatant above the pellet, or centrifugation in a decanter centrifuge. The centrifugation may be followed by disc centrifugation and/or filtration (e.g., using activated carbon) to remove residual protein source material and/or other impurities. The separation step may be conducted at various temperatures within the range of 1° C. to 100° C.

This example illustrates a method for preparing a succinylated refined protein useful in the compositions, formulations and methods of the present disclosure.
Materials and methods: Pea Flour (Ingredion, Westchester, Ill.) was added to distilled water adjusted to pH 8.5 using 6N sodium hydroxide while stirring for approximately 30 to 60 min to a final solids concentration of 20 wt/wt %. The pea flour extract was separated by centrifuging at between 5,000 to 15,000 g for approximately 10 minutes. The supernatant was retained as the extract whereas the pellet was discarded. The supernatant was centrifuged again to clear (or substantially clear) it from solids. Succinic anhydride (0.5 g succinic anhydride/g protein) was slowly added to the supernatant while stirring. Throughout the addition 6N sodium hydroxide was added to maintain pH of the mixture around 8-9. The succinylation reaction with the protein was complete after all of the succinic anhydride was added and the pH stabilized at pH 8-9. The resulting succinylated pea protein was then precipitated from the solution by adding 500 mM CaCl2) to a final concentration of approximately 50 mM, and adjusting to pH 3 using 6N hydrochloric acid while mixing briefly. The succinylated protein formed as a white precipitate that was separated by centrifuging at between 5,000 to 15,000 g for approximately 10 minutes. The supernatant was discarded, and the precipitate/pellet/paste was washed twice with water adjusted to pH 3 using 6N hydrochloric acid. For each wash water was added to pellet for a final dilution of 25-50×(˜1-2 mL solid pellet mixed in 50 mL water; briefly mix up; acidified with 6N hydrochloric acid; centrifuge as above, repeat).

Materials and methods: Unmodified refined pea protein paste (control) was prepared as in Example 1 but without any addition of succinic anhydride and with the precipitation pH adjusted to pH 5.5. Succinylated refined protein paste was prepared as in Example 1. Both control and succinylated protein pastes were dissolved at 10 wt % in separate water solutions of ˜150 mL. Aliquots (5 mL) of each solution were removed and checked for total protein content using protein combustion analysis on a Leco CN828 (Leco Corporation, St. Joseph, Mich., USA). Titration of each solution was carried out with 1N hydrochloric acid and 1N sodium hydroxide. Aliquots (5 mL) of each solution at different pH points were removed, then twice spun down (3500 rpm/5 min and 10,000 rpm/5 min), and supernatant of each was checked to determine soluble protein content. The soluble protein % was calculated by dividing the soluble protein by the total protein content.

This example illustrates compositions and methods for preparing non-dairy analog products using a succinylated refined protein component of the present disclosure.
An exemplary non-dairy analog can be formulated and prepared based on the composition of ingredients shown in Table 1.
Materials and methods: Dipotassium phosphate, dry flavor, vitamin blend, and gums are combined in a dry blend. Oil is combined with lecithin to obtain an oil blend. The refined protein component is added to the water with mixing for approximately 3 minutes at ˜2,000 rpm to obtain a liquid blend. Phosphate salts are added to the liquid blend, and it is allowed to mix for another minute. The dry blend, oil blend, and liquid flavoring agents are mixed into the liquid blend for approximately 5 minutes at ˜2,400 rpm. 45% Potassium hydroxide is added to adjust the pH to 7.8 (+/−0.05 at 5° C.). The blend is subjected to microthermics with in line homogenization (direct, 145° C., 6 seconds, 2,500 psi). The resulting non-dairy analog product is collected and cooled.
Table 1 provides a range of values for the composition of the ingredients that can be used in preparing a non-dairy analog of the present disclosure. For example, it is contemplated that variations to the amount of unmodified refined protein component used and the amount of succinylated refined protein used. For example, certain exemplary embodiments may use between 0-50% by weight of unmodified refined protein with between 100-50% by weight of the succinylated refined protein. In addition, variations in the formulation of the non-dairy analog of the present example are also contemplated as illustrated in Table 1. For example, different flavoring agents (e.g., natural sweetness enhancer flavor and natural chocolate type flavor, or natural vanilla flavor and vanilla extract) may be used to produce flavored non-dairy analogs (e.g., chocolate non-dairy analog or vanilla non-dairy-analog, respectively). Additionally, different phosphate salts (e.g., potassium phosphate, dipotassium phosphate, sodium phosphate, tricalcium phosphate, and disodium phosphate) may be used to produce certain non-dairy analogs (e.g., milk, barista style milk, and creamer).
This example illustrates experimental studies used to determine effects of pH and succinylating reagent concentration on preparation of a succinylated pea protein with improved solubility properties for use in non-dairy analogs. Briefly, pea protein was treated with the succinylating reagent, succinic anhydride (“SA”) under three different pH conditions (all with 20 wt % SA used) and six different weight percentages of SA to protein ranging from 5 wt % to 50 wt %.
Materials and methods: Succinylation was carried out on pea protein extracted from pea protein concentrate. A range of ratios of succinic anhydride reagent to protein concentrate was used to identify a minimum amount of succinylation sufficient to lower the isoelectric point of the modified proteins and increase their overall solubility. The ratios used were 0.05, 0.075, 0.1, 0.2, 0.35, and 0.5 g anhydride per g protein. Succinic anhydride was added to the protein extract slowly while stirring. Throughout the SA reagent addition, 6N sodium hydroxide was added so as to maintain a pH of 8-10. The succinylation reaction was complete after all the succinic anhydride was added and the pH had stabilized at 8-10. The protein was precipitated from the reaction mixture using 6N phosphoric acid to decrease the pH down to 3. Precipitation was also carried out of an unmodified (control) protein extracts using 6N phosphoric acid to decrease the pH to 5.5.
Titration of the precipitated succinylated and unmodified (control) protein pastes (5 wt % in separate water solutions of ˜150 mL) was carried out using 1N sodium hydroxide. Aliquots (5 mL) of each solution were removed during titration and total protein content was measured by protein combustion analyzer. All aliquots were then spun down (3500 rpm/5 min), and soluble protein content in each supernatant was measured by protein combustion analyzer. The soluble protein % was calculated by dividing the soluble protein by the total protein content.

This example illustrates experimental studies used to determine the effects of using succinylated pea protein (relative to unmodified pea protein) during preparation of refined protein component by precipitation. Briefly, succinylated pea protein extract, prepared as described in Example 6, was precipitated at pH 3 and 60° C. to prepare a succinylated refined protein, generally as described in Example 2. This succinylated refined pea protein was tested for solubility relative to unmodified control refined pea protein.
Materials and methods: Similar to Example 6, pea protein succinylation was carried out on pea protein extracted from pea protein concentrate using a ratio of 10 wt % SA to protein at pH 10. Protein was precipitated using phosphoric acid to adjust the pH down to 5.5 and 3 for unmodified and succinylated protein extracts respectively. Titration of unmodified (control) and succinylated protein pastes was performed as described in Example 6.
Results: As shown by the plot depicted in
Additionally, the yield of the succinylated refined pea protein from the precipitation process was about 5% higher. Specifically, the precipitation yield of the succinylated protein was 91.7% (versus 85.5% for the control) and the total yield was 70.4% (versus 65.9% for the control). Succinylation did not significantly affect the color of the precipitated refined pea protein product, as shown by the very similar CIELAB color space values for control and succinylated protein, which are L=75.16, a=4.73, b=20.70, and L=75.69, a=4.57, b=17.88 respectively.
This example illustrates an alternative preparation of a succinylated refined pea protein in which the succinylation reaction is carried out “post-purification” using a spray-dried isolate of pea protein. Briefly, a spray-dried protein isolate is prepared at manufacturing scale, reconstituted at pH 7, 8, or 9, and then treated with succinic anhydride at these three pHs. The solubility of the three succinylated protein solutions prepared by this method was determined relative to the unmodified protein.
Materials and Methods: spray-dried protein isolate was prepared at manufacturing scale using a process similar to that described in Example 1, except without the succinic anhydride addition. The precipitated protein isolate was reconstituted with deionized water to create a 5% protein solution which was then separated into four aliquots of 200 mL and adjusted to pH 7, 8, 9, or 10 with 6N sodium hydroxide. The solutions at pH 7, 8, and 9 were treated with 10 wt % succinic anhydride and mixed for 5 minutes. The solution at pH 10 was not treated and used as the unmodified control sample. The solubility of the succinylated proteins prepared by this method was determined relative to the unmodified protein by titration as described in Example 6.
Results: As shown by the solubility plots depicted in
This example illustrates experimental studies that spray-dried succinylated refined pea protein prepared at pilot scale (˜120 kg batch) exhibits improved solubility at acidic pH 6 and improved foaming relative to the unmodified refined pea protein.
Materials and materials: Extraction batches of 120 kg were prepared in a tank by mixing 108 kg of hot tap water and 12 kg of pea protein concentrate (PulsePlus Pea Protein 55, AGT Foods, SK, Canada). The water was heated through a heat exchanger, targeting a batch temperature of 55-65° C. 6N sodium hydroxide solution was added to the slurry while mixing to pH 9. To produce modified protein, succinic anhydride salt was added in a ratio to protein of 10 wt % and agitated for 45 min. To produce unmodified protein (control) the succinic anhydride addition was omitted. This slurry was fed into an Alfa Laval Foodec decanter to separate the soluble protein from the insoluble ingredients (which are predominantly starch and fiber). The decanted soluble protein solution was collected in a drum, heated to 60° C. through a heat exchanger, and then fed continuously through a pipe with continuous addition of 75% phosphoric acid solution. The resulting coagulated protein slurry was collected in a tank and then washed with 20-60° C. water 3.5:1. This protein slurry was fed to an Alfa Laval Clara 20 disc stack and the solid discharge collected as the final wet purified protein product. This wet product was pasteurized and spray-dried to a powder. Solubility of the modified and control protein isolates was measured as described in Example 6.
The foaming production of the modified and unmodified (control) powder was evaluated as follows. 75 mL of 3% protein in water solution was prepared, adjusted to pH 6.5, and mixed for 1 min in an electric milk frother (Epica, Brick, N.J., USA). The foamed solution was poured into a graduated cylinder and the volumes were noted. Foam expansion % was calculated as volume after foaming over initial volume of the sample.

Non-dairy analogs were prepared from these modified and succinylated refined pea protein isolates as described below. The feathering of each non-dairy analog in coffee was then determined.
Materials and methods: Phosphate salts and gums are combined in a dry blend. Oil is combined with lecithin to obtain an oil blend. The refined protein component(s) and liquid flavors are added to the water and mixed for approximately 3 minutes at ˜8,000 rpm to obtain a liquid blend. The dry blend is added to the liquid blend, and it is allowed to mix for another minute. The oil blend is mixed into the liquid blend for approximately 1 minute at 8,000 rpm. Potassium hydroxide is added to adjust the pH to 7.8 (+/−0.05 at 5° C.). The blend is subjected to homogenization (2,500 psi) and direct steam injection thermal process (140° C., 4 seconds). The resulting non-dairy analog product is collected and cooled.
Feathering characteristics of the control (unmodified) and succinylated protein non-dairy analogs were determined in coffee as follows. Two unsweetened non-dairy analogs were prepared as described in Example using either 100% unmodified pea protein, or 100% succinylated pea protein. The non-dairy analogs were maintained at a temperature of between 2-8° C. Coffee was heated to 65-70° C. prior to mixing with each of the non-dairy analogs. 200 mL of coffee (pH 5.4) was poured into a beaker and the non-dairy analog (4.75 g, 0.3 TBS) was added. Solutions were stirred clockwise 5 times and an additional 5 times counterclockwise. Images taken of solutions after 5 min and are shown in
