【摘要】 本文利用二次旋转回归实验设计深入探讨了不同水解条件对胰蛋白酶水解乳清蛋白的影响,建立了各主要因素参数与水解度之间的回归模型,依据该模型优化了胰蛋白酶对乳清蛋白的水解条件:温度52.3℃、初始pH值8.37、酶量2.5%、乳清蛋白浓度6%、水解时间12小时。更多还原

【Abstract】 The effect of different condition on trypsin hydrolyzing whey protein were deeply studied through dual quadratic rotary combinational design.The model of the degree of hydrolysis(DH)with the selected parameter during hydrolysis have been created.Accarding to the model,the optimized hydrolysis conditions for the trypsin hydrolyzing whey protein was obtained temperature:52.3℃,pH in the beginning:8.37,[E]: 2.5%,[S]:6%,time of hydrolysis:12h.更多还原
