摘要
研究了Alcalase水解大豆蛋白制备大豆蛋白寡肽时影响水解效果的各种因素,在此基础上通过正交试验确定了Alcalase水解大豆蛋白的水解条件:温度70℃,底物浓度60g/L,Alcalase酶与底物比为20μL/g,pH7.5,水解时间为4h。在此水解条件下,水解液水解度达到了24.1%。
The effects of several factors on the alcalase-catalyzed hydrolysis of soybean protein, such as the enzyme dosage, temperature, pH value and reaction time, were studied. The orthogonal test showed that the optimized hydrolysis conditions were as follow： pH value of 7.5, reaction temperature of 70℃, alcalase dosage of 20 μL/g protein, substrate concentration of 60 g/L, and total reaction time of 4 h. Under these conditions the hydrolysis degree of soybean protein reached 24.1%.
