This product is a digestive enzyme, which can resolve protein coagulated by gastric action into peptone but not further into amino acid. Its digestion is the highest when hydrochloric acid amount only reaches 0.2%-0.4% (pH=1.6-1.8), therefore it is usually combined with dilute hydrochloric acid. It is clinically applied to indigestion caused by eating too much protein food, chronic atrophic gastritis caused by convalescent decreased digestive function, gastric cancer and anapepsia caused by pernicious anemia. It is mainly used for nutritional supplement and enzymic preparations.

2. enzyme preparation. Mainly used for the manufacture of fishmeal and other proteins (such as soy protein) hydrolysis, cheese in the manufacture of curd effect (in combination with the bilirubin), can also be used to prevent beer frozen and turbid.

3. For biochemical research, protein structure analysis, medicine used as digestive enzymes.

4. To help digestive drugs, for the lack of pepsin or digestive dysfunction after the disease caused by indigestion.

5. In addition, in the manufacture of milk cool when used as a substitute for dry stomach
