摘要:  对低值鱼蛋白原料以及鱼加工下脚蛋白料等的蛋白适度水解工艺进行了研究,探讨了酸催化水解处理、蛋白酶酶解处理的最佳工艺条件;获得了先以柠檬酸进行催化水解处理,再以胰蛋白酶、木瓜蛋白酶两种酶的特定比例混合进行酶解处理的两步水解新工艺,即酸水解后再加两种酶以特定比例混合进行酶解的复合水解工艺。

Abstract: Acidic and enzymatic hydrolysis processes of low value fish protein from small hairtail and offal of fisheries were investigated.Conditions for acidic and enzymatic hydrolysis of fish protein were optimized and a multi-process of acidic and enzymatic hydrolysis was developed.This process consists of pre-treatment of hairtail and offal by citric acid,followed by hydrolysis with trypsin in a proper proportion with respect to papain.
