摘要:

用Alcalase碱性蛋白酶对草鱼蛋白质进行酶解,比较酶的添加量、pH值、温度、料液比以及酶解时间对草鱼蛋白水解进程的影响,通过响应面法优化Alcalase碱性蛋白酶酶解反应的工艺条件。结果表明:Alcalase碱性蛋白酶酶解草鱼蛋白质的最优工艺条件为:加酶量1.8%、酶解温度55 ℃、酶解pH 9.0、料液比1∶15、酶解时间180 min,此条件下蛋白质水解度达到23.46%。

关键词: 草鱼蛋白, 酶解, 响应面

Abstract:

This study aimed to optimize the conditions for enzymatic hydrolysis of grass carp proteins. Alcalase was used
to hydrolyze grass carp proteins. The effects of enzyme/substrate ratio, pH value, temperature, material/liquid ratio and
hydrolysis time on the degree of hydrolysis were analyzed. Box-Behnken design (BBD) and response surface methodology
(RSM) were adopted to obtain the optimum hydrolysis conditions on the basis of results of single-factor experiments. The
degree of hydrolysis of 23.46% was obtained under the optimum hydrolysis conditions of 1.8%, 55 ℃, 1:15, 180 min and 9.0
for enzyme/substrate ratio, temperature, material/liquid ratio, hydrolysis time, and pH, respectively.

Key words: grass carp protein, enzymatic hydrolysis, response surface methodology
