Stomach protease is a digestive protease secreted by the main cells of the gastric mucosa in the stomach. Its function is to break down proteins in food into small peptide fragments. The industrial production of gastric protease is mainly extracted from the glandular stomachs of animals such as pigs, cows, and sheep, and is purified and extracted through a process. Mainly used in cheese production, protein hydrolysis, and pharmaceutical raw materials.
Pepsin can be used for curd making. It can cause casein in milk to coagulate and form curd blocks, thereby separating whey and curd, laying the foundation for the formation of cheese. Compared with other rennet enzymes, pepsin has a better coagulation effect and can give cheese a good texture and flavor.

Notices
1. Enzyme preparations are bioactive substances that are susceptible to the inhibitory and destructive effects of heavy metal ions (Fe3+, Cu2+, Hg+, Pb+, etc.) and oxidants. Contact with them should be avoided during use and storage;
2. For people who are easily sensitive, it may cause hypersensitivity reactions; Close contact or slight inhalation may irritate the skin, eyes, and mucosal tissues; During the use of enzyme products, it is recommended to wear protective equipment such as masks and eye masks.
3. Moisture proof, light proof, sealed and stored at low temperature (0-10 ° C) for 18 months. Enzymes experience a certain loss of enzyme activity during storage, with 5-10% loss of enzyme activity at 10 ° C for 6 months and 10-15% loss of enzyme activity at room temperature for 6 months.
4. Extending the storage period or being affected by harsh storage conditions such as high temperature and humidity can lead to an increase in usage.
