Alpha Glucoamylase, also known as glycosylase. It is an efficient biological preparation made by liquid fermentation and purification of Aspergillus Niger introduced from the United States. It can be used in the saccharification process of beer brewing to improve fermentation degree and yield in the saccharification stage.
Alpha Glucoamylase Characteristics
The enzyme can hydrolyze the c-1, 4 bonds successively from the end of the starch chain, At the same time, starch can be slowly hydrolyzed into glucose by the bond 1,6. 1 ml of enzyme solution, which can hydrolyze soluble starch to produce 1mg glucose within 1 hour, is a unit of enzyme activity (u/ml).
Alpha Glucoamylase Operating Conditions
Temperature: pH value:
Optimum temperature range: 58 ℃ to 65 ℃; Optimum pH range: 4.0-6.0;
Effective temperature range: 55 ℃ to 70 ℃. Effective pH range: 3.0-6.5.
Alpha Glucoamylase Effect of Efficacy
Improve fermentation degree and improve the yield of the saccharification stage.
