Compound enzyme preparation (high temperature resistant α-amylase)

  • High temperature resistant a-amylase is refined by fermentation and extraction of Bacillus licheniformis. This product has particularly good high temperature resistance characteristics. It is widely used in alcohol, beer, vinegar, soy sauce, textile printing and dyeing, paper making and other fermentation fields.

Principle:

Used in the pasteurization process of beer production carried out by the addition of auxiliary materials to break down the starch in starchy raw materials into short-chain dextrins and a small amount of oligosaccharides, which facilitates the saccharification process.



Characteristics:

Temperature range: Effective temperature range 55-100℃, suitable working temperature is 80-97℃, 100℃ can still maintain considerable vitality, when spraying liquefaction, the instant temperature can reach 105-112℃.

 PH range: effective PH range 4.3-8.0, suitable PH range 5.2-6.0.



Application :

In the process of beer brewing, the auxiliary materials in the paste pot are mixed well with the ratio of material and water of 1:3-5, and the enzyme is added 0.3L/kg per ton of auxiliary materials (20000 units), and the temperature is raised to 92-97℃, maintained for 20-30 minutes, and the color of iodine test is reddish-brown when the temperature is raised to 100℃ for heat preservation.



Product use safety and precautions: 

Enzymes are protein-based substances, for sensitive people, inhalation of enzyme powder or dew drops may cause allergic reactions, too long exposure may irritate the skin, eyes and mucous membrane tissues. It is recommended to wear a mask for protection during operation. If the product is accidentally splashed on the skin or eyes, please flush with water immediately.

After each opening of the bag or bucket, if not used up, the bag should be tied tightly or the bucket lid should be screwed tightly to avoid inactivation of the effective active ingredients.
