Food Grade Acid proteinase is a type of endonuclease and exonuclease extracted from Aspergillus niger through fermentation and refinement. It has a pH value of 2.0~4.0 and can cleave peptide bonds composed of a wide range of amino acids at a certain temperature, pH value, and substrate concentration. The products are small peptides and amino acids, which are widely used in industries such as brewing, food processing, feed additives, and leather 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.
