Method for processing soy protein and composition of matter

摘要: A method for processing soy protein from defatted soybean flakes. Flakes are mixed with water and heated to an elevated temperature of about 55° C. 70° extract solubles therefrom. The liquor is cooled over a period time at least one three hours 5° 10° resulting in curd whey. separated the whey preserved preferably by either freeze-drying or spray-drying. can be redissolved water, precipitated addition acid, followed washing precipitate, adjustment pH washed precipitate drying thereof. which initial was may processed series steps generally involving precipitation additional curd, redissolution pH, curd. Four distinct fractions result, each having differing unique physical and/or functional properties.
