Application of Acid proteinase for food and soy sauce fish sauce customized enzyme activity specifications

    Acid protease is a type of proteolytic enzyme capable of decomposing proteins under acidic conditions (with a pH range of 2.0-5.0). Produced through fermentation and extraction using Aspergillus niger, its mode of action involves hydrolyzing peptide bonds—this process breaks down large-molecular-weight proteins into small-molecule peptides or amino acids, which in turn boosts the utilization rate of raw materials or enhances the properties of the final product.

Conventional hydrolysis: 1-6 hours,

Fermentation type: determined by fermentation time

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.
