Preparation of cured fish products
1. Proteolytic enzymes may be used as processing aids in preparing ripened, salted fish
2. In traditional cured fish products, a partial proteolysis occurs by endogenous enzymes
⑴ This is caused by muscle proteases
⑵ The activity of these muscle proteases is small compared to that of gastrointestinal tract
⑶ These fish protease play a decisive role in the maturing or ripening process of meat
(4) Production of herring products by maturing process originates from Scotland in the 8th century
