High- temperature a-amylase(food additive)

High-temperature a-amylase (food additive) High-temperature a-amylase is extracted from bacillus licheniformis’s submerged fermentation. Be suitable for biological pharmacy, starch sugar, alcohol, beer, monosodium glutamate, fermentation textile and etc. Properties: It is a kind of incision enzyme, that can hydrolyze starch, soluable dextrin and a-1, 4 dextrose 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 10000u/ml, 20000u/ml, 30000u/ml the optimum PH 5.5-7.0 the optimum temperature Above 90°C( for continuous jet liquefaction, the temperature is 100-105°C) Recommended Dosage: 0.2-1kg/starch( per ton) Application: Beer Industry: after raw material and water evenly mixed, add 0.3L amylase(20000u/ml) for per ton and raise temperature rapidly, the optimum effect will be reached at 95-97°C. When the temperature reaches 100°C and keep for 30 minutes, the finishing of liquefaction can be tested by lodine test. Alcohol Industry: the suitable diameter is 1.5mm, evenly mix up raw material and water in ratio 1:3.5-4.0 and keep water temperature at 45-55°C. Add 0.6L amylase(20000u/ml) for per ton, stir and pump into boiling heater, keep the temperature at 95-105°C for 100 minutes, then cooling for saccharification. Monosodium Glutamate,Maltose, Dextrose Industry: make starch emulsion according to technology requirement, adjust PH at 6.2 and then add 0.6-0.7L amylase(20000u/ml) for per ton. If adopt intermittent liquefaction, raise tank temperature to 95-100°C and keep for 30 minutes. For jet liquefaction technology, jet temperature should around 105°C or keep for 60 minutes at 95°C until complete liquefaction. Package: 25kg/barrel or subject to client requirement.
