Abstract: A non-fat milk replacer for baking containing an isolated vegetable protein ingredient is disclosed. The milk replacer is produced by forming a slurry containing 94-48% by weight dairy whey, 6-52% isolated vegetable protein, said slurry having a pH of 5.8-7.5 and an added alkaline earth cation concentration of 0.1 to 2.0% by weight of the solids. The slurry is heated within a critically defined temperature range of 190.degree.-230.degree. F. for a period of time sufficient to partially insolubilize the protein, followed by cooling and drying of the slurry to form a non-fat milk replacer which has comparable baking properties to non-fat dry milk.

Abstract: The present invention provides a process for the production of a protein isolate having low solubility with excellent functional properties as a complete or partial replacement for milk co-precipitate in a non-aqueous, "creme" filling used in cookies, snacks and the like. The process comprises; forming an aqueous slurry of an isolated soy protein; controlling the pH of the slurry to between about 4.5 to 5.8 by the addition of a monovalent alkali reagent; heating said slurry to a temperature of between about 170.degree.-240.degree. F.; and neutralizing said slurry to a pH of 6.8 to 7.2 in the presence of an alkaline earth cation to provide a low solubility protein isolate.
