Abstract
A process particularly designed to further improve soy protein previously denatured by superheating treatment or alcohol extraction comprises heating an aqueous slurry of the denatured, defatted soybean flake material under prescribed conditions. Nitrogen values, flavor and color are improved.
Claims11
A process for preparing soy protein material having improved solubility which comprises preparing an aqueous slurry of denatured defatted soybean flake material, wherein said aqueous slurry is adjusted to pH 6.5 to 9;
- heating said aqueous slurry to a temperature in the range of about 110.degree. to 140.degree. C;
- and subsequently retaining the heated slurry at a temperature in said range for from 2 seconds to 3 minutes;
- wherein the NSI of said denatured defatted soybean flake material is not more than 70%, and the NSI of the soy protein in the resultant heated and retained slurry is not less than 75%.
