Physical and Chemical Properties | Near white to light brown amorphous powder, or light brown to dark brown liquid, can be dispersed in food-grade diluents or carriers, can also contain stabilizers and preservatives. It can hydrolyze the α-1,4-and α-1,6-glycoside bonds of polysaccharides (starch, glycogen, etc.) to form glucose. Soluble in water, almost insoluble in ethanol, chloroform and ether. |
Use | Used for glycogen determination in yeast cells; relying on glucoamylase to synthesize iso-oligosaccharides. Glucoamylase can cut the a-1 -4 and a-1 -6 glycosidic bonds of starch molecules at normal temperature and convert starch into glucose. |
Risk Codes | R36/37/38 - Irritating to eyes, respiratory system and skin. R42 - May cause sensitization by inhalation R41 - Risk of serious damage to eyes R40 - Limited evidence of a carcinogenic effect R37/38 - Irritating to respiratory system and skin. R24 - Toxic in contact with skin R20/22 - Harmful by inhalation and if swallowed. |
Safety Description | S26 - In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S36 - Wear suitable protective clothing.

is brown liquid. Soluble in water, insoluble in ethanol, chloroform and ether. The optimum pH value was 4.0~4.5, and the optimum temperature was 60.
The mutant strain of Aspergillus niger was prepared by fermentation.
saccharifying enzymes can catalyze the hydrolysis of starch to produce beer, rice wine, sauce flavor and antibiotics; They are also used in the production of raw pulp such as glucose, maltose and dextrin.

Application | Glucoamylase is a kind of amylase, which can be used in alcohol and alcohol, amylase and other fermentation industry of starch material saccharification. |
Application status | in recent years, with the development of biotechnology, when Glucoamylase and active dry yeast are used in alcohol industry and liquor-making industry, the product quality can be stabilized, the amount of Koji used can be reduced, the grain consumption can be saved, the alcohol yield can be increased, and the yield and production safety can be increased, and promote the industry's technological progress and technological transformation. |
toxicity | ADI is not specified (FAO/WHO,2001). |
usage limit | GB 2760-1996: Starch Manufacturing, brewing, juice processing, all GMP. FDA § 173.110(2000): 0.1% of the amount of gelatinous starch. |
Use | This product can catalyze the hydrolysis of starch to produce beer, rice wine, sauce, monosodium glutamate and antibiotics; It is also used for glucose, production of sugars and dextrins, etc. China's provisions can be used for fermented wine, distilled wine, alcohol, starch syrup production, according to the production needs of the appropriate amount of use. for glycogen determination in yeast cells; Synthesis of ISO-oligosaccharides by Glucoamylase biochemical studies |
production method | this enzyme mainly comes from rhizopus and Aspergillus niger. In the production of the main use of Aspergillus niger variant strains AS.3.4309 (referred to as UV 11) as the production of bacteria, corn flour (10% ~ 12%), soybean meal 4%, corn steep liquor 2%, bran 1% and so on as the culture medium, deep culture for 100H; Fermentation liquid was refined and dried to obtain powder. isolated from the culture medium following controlled fermentation by Aspergillus niger var. Preparation of starch syrup and juice; Cheese making. |
