alpha-Amylase powder Usage and Synthesis.

1 Food processing: As a safe and efficient improver in the flour industry, it can improve the quality of bread. A-amylase has liquefaction and saccharification effects and is often used as a sweetener in the beverage industry. In the cold drink, the viscosity of the cold drink is reduced, the fluidity is increased, and the taste of the high starch cold drink is ensured. As a new liquefaction enzyme preparation, high temperature A-amylase is widely used in fermentation industry. Its thermal stability is determined by the thermal stability of protein itself, so it is widely used in alcohol and beer brewing industry.

2 Feed industry: Adding exogenous A-amylase to the diet can help young animals digest and utilize starch, and its growth performance and feed conversion rate are very beneficial. Adding live Escherichia coli culture producing A-amylase to broiler diets can act as an antibiotic growth promoter, improve intestinal morphology and improve production performance.

3 Washing industry: Because starch is cheap, easy to obtain and easy to remove, it is used as a layer of protective material to prevent yarn breakage in modern fiber manufacturing processes, and then the use of A-amylase for treatment, which can selectively remove the starch pulp without harming the yarn fiber, and can also degrade the starch into dextrin which is easily soluble in water, making it easy to wash off.

4 Pharmaceutical industry: Because Aspergillus Niger A-amylase has acid resistance, it can be used to manufacture drugs to help digestion, and develop acid-resistant A-amylase suitable for stomach acid environment for the preparation of digestive AIDS.

5 Paper industry: Amylase in the paper industry is mainly used to improve the viscosity and concentration of paper coating starch. Paste is a good paper coating, can improve the hardness and strength of paper, enhance the friction of paper, and the starch concentration in nature is too high for paper pulping, so it can be partially reduced by A-amylase starch to adjust.

Uses of alpha-Amylase powder.

α-amylase is a metallic enzyme, which is inhibited by many metal ions, especially heavy metal ions. In addition, sulfhydryl, n-bromosuccinic imide, p-hydroxymercuric benzoic acid, iodoacetic acid, BSA, EDTA and EGTA have significant inhibitory effects on α-amylase. Among them, α-amylase contains at least one Ca2+, Ca2+ can make the enzyme molecule maintain the appropriate conformation, so as to maintain its maximum activity and stability. The affinity of Ca2+ to α-amylase is stronger than that of other ions, and the number of Ca2+ binding calcium ions is between 1-10

There are certain differences in the properties of α-amylase from different sources, and the main applications in industry are fungal and bacterial α-amylase. At present, α-amylase has been widely used in feed, modified starch and starch sugar, baking industry, beer brewing, alcohol industry, fermentation and textile industries, and is an important industrial enzyme.

Pharmacological action of alpha-Amylase powder.

Preparation method of Bulk alpha-Amylase powder.

This enzyme is mainly derived from Bacillus subtilis, microbial bacteria and Aspergillus. Bocillus subtilis BF7658 was commonly used as production bacteria, and soybean cake powder (4%-6%), corn flour (4%-10%) and some inorganic salts were used as medium for deep culture for 40 ~ 48h. The fermentation solution is precipitated with alcohol or salted out with ammonium sulfate to obtain the product. In order to facilitate storage, an appropriate amount of calcium carbonate is often added as an anti-coagulating agent.
