Αlpha-galactosidase also has a transgalactosylation effect in the case where the substrate concentration is highly enriched, and this feature can be used for the synthesis of a terpene polyester and the preparation of a cyclodextrin derivative. Alpha-galactosidase is a non-side-effect biological enzyme preparation for the development of functional foods, and has been certified as a safe substance by FDA, GRAS, WHO/FAP, and JACFA.

4.Standard: GB/T 1886.174 -2016 (enzymes for food industry)
5.Enzyme activity definition:
6.One galactosidase activity unit (GalU) is defined as the quantity of the enzyme that will liberate p-nitrophenol at the rate of 1 μmol/min under the conditions of the assay.
7.Effects of metal ions on enzyme activity: certain concentrations of Cu2+, Zn2+, Mn2+, Fe2+, Mg2+ have activating effects, EDTA, Ba2+ and Ag+ has inhibiting effects.
APPLICATION:
It can effectively catalyze α-galactosidic linkages and hydrolyze other anti-nutritional factors, reduce the incidence of digestive viscosity and diarrhea, and eliminate vegetative and animal bloating. It can destroy the cell wall structure of plants, promote nutrient release, improve utilization efficiency, enhance immune function and disease resistance, and reduce the amount of antibiotics in feed. It can improve the bleaching effect of paper by combining with xylanase, mannan plum and α-galactosidase. It can also be used in the synthesis of sterol and in the preparation of cyclodextrin derivatives.
PACKAGING: 20KG/drum, 25KG/drum
STORAGE AND SHELF LIFE: 2 years when stored at room temperature, away from sunlight, cold storage is better
