摘要
选用木瓜蛋白酶水解大豆分离蛋白，对原料预处理条件，酶解条件进行了研究。实验结果表明：原料预处理最佳条件为：水中８０℃处理１５ｍｉｎ，酶解最佳条件为：底物浓度４５％，酶浓度９０００ｕ／ｇ，ｐＨ７，５５℃。
Soybean protein isolate (SPI) is hydrolyzed with papain,the condition of denaturation,enzymatic hydrolysis are studied systematically.Experiments show that the optimum conditions are:denaturation of SPI by heating in water at 80℃ for 15 min,enzymatic hydrolysis of SPI::4.5%,:9 000 u/g ,pH7,55℃.
