Adore the papain to hydrolyze the protein of Clarias fuscus and study the process condition of enzymolysis. Analyse the influence of dosage of papain, concentration of substrate, temperature of enzymolysis, pH value etc. On the protein hydrolysis of Clarias fuscus Experimental results show that the best condition of the enzymolysis as follow: the concentration of papain at 1.8 %, the concentration of substrate at 3.5 %, the temperature of enzymolysis at 55℃, pH 7.0, time of hydrolysis at 6 h, in which the hydrolysis will be 30.65%achieved.% 采用木瓜蛋白酶水解胡子鲶鱼蛋白，并对酶水解的工艺条件进行研究，分析了酶用量、底物浓度、酶水解温度、酶水解时间、pH等因素对胡子鲶蛋白水解的影响。实验结果表明，木瓜蛋白酶水解胡子鲶的最佳条件为：酶浓度1.8%，底物浓度3.5%，酶水解温度55℃， pH 7.0，反应时间6 h ，在此条件下胡子鲶水解程度可达到30.65%。
