[0003] The viscera and muscles of aquatic animals are rich in proteases. According to the pH conditions of action, they can be divided into acidic proteases and neutral to alkaline proteases. Acidic proteases mainly refer to digestive enzymes from the stomach, such as pepsin, chymosin, gastric protease, etc. In addition, the optimal pH of tissue proteases in muscles is around 5.5. Neutral to alkaline proteases mainly come from intestinal digestive enzymes, such as trypsin, chymotrypsin, etc. According to the active center of protease action, it can be divided into four major families: serine proteases, aspartic acid proteases, cysteine ​​proteases and metalloproteases.
