What is Glucoamylase ?
Glucoamylase is a customary name, and its scientific name is α-1,4- glucohydrolase. It is widely used in alcohol, starch sugar, monosodium glutamate, antibiotics, citric acid, beer and other industries, as well as liquor and rice wine. Glucoamylase is extracted from Aspergilusniger by submerged fermentation.Glucoamylase is a nearly white to light brown amorphous powder, which can be dispersed in food-grade diluents or carriers, and can also contain stabilizers and preservatives. It can hydrolyze α-1,4-and α-1,6-glycosidic bonds of polysaccharides (starch, glycogen, etc.) to form glucose. Soluble in water.

How does Glucoamylase work and store ?
Mode of action
Biochemical research can quickly liquefy starch to produce low molecular weight dextrin. Glucoamylase can catalyze the hydrolysis of starch to produce beer, yellow wine, monosodium glutamate and antibiotics, and can also be used for the production of glucose, maltose and dextrin. The activity of this product increases with the increase of temperature, and decreases sharply with the increase of temperature when it exceeds 65℃. The optimum temperature of this product is 60-62℃. The optimum PH value is about 4.0-4.5.
Transportation and storage
Glucoamylase is sensitive to temperature, light and humidity. Avoid exposure, high temperature and humidity as much as possible during transportation and storage, and keep it clean, cool and dry. Glucoamylase can be stored at low temperature better.
