Pepsin is generally extracted from the stomachs of pigs, cows, and sheep. It belongs to the aspartic acid type endonuclease and can break down peptide bonds formed between phenylalanine or tyrosine and other amino acids in proteins. The products are peptone and a small amount of peptides and amino acids. Pepsin has high activity in acidic environments, but in solutions with neutral or alkaline pH values, it undergoes melting and loses activity. Commonly used for protein hydrolysis and food processing.

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.
