Product name:Tannase

Other names: Tannin acylhydrolase

CAS:9025-71-2

Chemical properties: Tannase(9025-71-2) traits:     It enables the hydrolysis of tannins as tannic acid, glucose and gallic acid optimum pH value of 5.5 to 6.0, the optimum temperature of 33 ° C. Soluble in water, insoluble in ethanol. Its appearance is pale black powder. 

Purposes: Tannase (9025-71-2), use:     Can be used to contain tannin or tannic and chlorogenic acid conjugates In addition to the astringent effect. However, the decomposition of which is mainly used in the production of instant tea tannin to improve the finished product cold insoluble and avoid hot melt cooling muddy. When used at pH 5.5 to 6 tea extract solution, by adding a proportion of plus 2.5g tannic acid enzyme preparation per liter, and then stirring 70min at 30 °C, and then heating to 90 ° C for enzyme inactivation, centrifugation to remove the tannic acid enzymes can be. 

Description: Preparation of the Tannase(9025-71-2):     Controlled training, generally in the presence of 2% tannic acid and 0.2% casein hydrolyzate by Aspergillus niger, Aspergillus oryzae or glaucum Penicillium Chua's medium to remove the mycelium, extracted with water, acetone precipitation, drying.
