Detailed Description
Syder Brand Medium temperature α-Amylase preparation is produced via submerged fermentation of Bacillus subtills and modern extraction technique.Optimal pH range: 6.0 to 6.5; Effective pH range: 6.0 to 7.0
Optimal temperature range: 60 to 70℃; Effective temperature range: 60 to 90℃
It will lose activities badly when pH is below 5.0. When the temperature is between 70 and 90℃, the reaction rate increases with the increment of the temperature, but the activity loss increases along with the temperature. It can be used in the liquefying process at temperature of 90℃. The increase in the concentration of starch improves the stability of enzyme activity. Calcium ion can improve the heat stability of the enzyme.
This product is applicable for liquification process in the production of starch sugar, alcohol, beer, monododium glutamate and in other fermentation industry, and the desizing of textile, printing and dyeing. When this product is used in alcohol, citric acid, fermentation industry and other food processing, the dosage and application condition of the enzyme could be decided through experiments according to its characteristics.
