中温α-淀粉酶（食品添加剂)

Mid-temperature Refining Alpha-Amylase (food additive) Mid-temperature a-amylase is extracted from Bacillus subtilis’s submerged fermentation. Be suitable for biological pharmacy, starch sugar, alcohol, beer, monosodium glutamate, fermentation industry, fruit juice, textile, paper-making and so on. Properties: It can hydrolyze starch, soluable dextrin and a-1, 4 dextrose lin glycosidic linkage of oligose. After the enzyme treatment, the viscosity of paste starch rapidly reduced, and hydrolyzed it into dextrin and a small amount of dextrose and maltose. Item Index Appearance Amber liquid Activity 1000u/ml, 2000u/ml, 3000u/ml Technology Parameter: The PH range is 5.5 - 7.5, the optimum PH is 6.0-7.0. The optimum temperature is 60°C-75°C. As the temperature grows, the reaction rate will fasted but the speed of inactivation will fasted at the same time; If the temperature is low, it suggest that lengthen the reaction time, the concentration of calcium ion should be 150-250mg/kg. Recommended Dosage: 4-10 unit/ starch (per g) Standard: QB1805.1-93 Package: 25 kg/barrel or subject to client requirement.
