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.

Key words:  , hairtail; protein; hydrolysis; enzyme; citric acid; multi-hydrolysis; amino nitrogen;
