摘要： A PROCESS FOR FORMING SOY PROTEIN CONCENTRATES AND SOY PROTEIN ISOLATES HAVING A HIGH SOLUBILITY IN WATER AND RELATED SOY PRODUCTS IS DISCLOSED. THE PROCESS INVOLVES MIXING DEFATTED, DEHULLED SOYBEAN MATERIAL IN THE FORM OF FLAKES OR MEAL IN WATER AT A TEMPERATURE OF BETWEEN ABOUT 175*F. AND 212*F. (TO DESTROY THE TYPSIN INHIBITORS, UREASE, ETC.) AND MAINTAINING A PH OF PREFERABLY BETWEEN 6.8 AND 9 THROUGHOUT THE PROCESSING. THE AQUEOUS SOYBEAN MIXTURE IS COOLED TO A TEMPERATURE BETWEEN 100*F. AND 140*F. PEROXIDASE ENZYMES MAY BE ADDED TO THE AQUEOUS SOYBEAN MIXTURE TO DECOMPOSE PEROXIDES CONTAINED THEREIN OR ANTIOXIDANTS MAY BE ADDED. THE INSOLUBLE MATERIALS ARE THEN SEPARATED, FROM THE WATER SOLUBLE SOYBEAN SOLUTION, AND MIXED WITH AN ALCOHOL-WATER SOLUTION, SUCH AS 70 PERCENT METHANOL, TO YELD (1) INSOLUBLE SOY PROTEIN AND (2) SEMISOLUBLE SOY PROTEIN. THE WATER SOLUBLE PORTION OF THE AQUEOUS SOYBEAN MIXTURE IS MIXED WITH AN ALCOHOL-WATER SOLUTION, SUCH AS 70 PERCENT METHANOL TO YIELD (1) SOY PROTEIN CONCENTRATES AND/OR (2) SOY PROTEIN ISOLATES AND (3) SOY WHEY SOLIDS AND SUGARS.
