β-lactase, also known as Beta-Galactosidase, is an essential enzyme that enables the hydrolysis of lactose into glucose and galactose. It is widely distributed in the human intestinal tract, milk, and microorganisms including yeast and lactic acid bacteria. The lactase found in the human gut is mainly produced and released by the epithelial cells of the small intestine, playing a key role in breaking down the lactose present in dairy items. A lack of adequate secretion of this enzyme leads to incomplete lactose digestion—undigested lactose then ferments in the intestines, producing gas and organic acids, which in turn induce symptoms of "lactose intolerance" such as abdominal bloating and diarrhea.

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.
