Alpha amylase is extracted from Bacillus subtilis through deep fermentation and can hydrolyze starch into various types of dextrins, as well as small amounts of low molecular weight sugars such as glucose and maltose. Thus, the viscosity of starch dextrin rapidly decreases, playing a role in liquefying starch, and is applied in industrial fields such as starch processing, food and beverage, textile, papermaking, fermentation, etc.

Thermal stability: The effective temperature range is 35-90 ℃, and it is relatively stable below 60 ℃. The optimal operating temperature is 60-70 ℃, and it can be applied to liquefaction processes up to 90 ℃.

PH stability: relatively stable at pH 5.0-6.0.

Applications:

·Beer;
·Alcohol production;
·Starch sugar;
·Textile industry: desizing process for silk, synthetic fiber, cotton and wool fabrics;
·Feed industry: improve digestion function and increase the energy utilization efficiency of the diet;
·Juice processing: Improve the transparency of juice and prevent turbidity;
·Fermented noodle products: improve finished product texture and extend shelf life;

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.
