Mid-Temperature Alpha-Amylase is widely used in starch sugar, alcohol, brewery, textile, dye & printing and papermaking,etc.
Working Mechanism:
The enzyme hydrolyzes the α-1,4-glucosidic linkages of gelatinized starch randomly to soluble dextrins, reducing the high viscosity of the starch slurry.
Property:
1. Temperature: Optimum 60-70°C,operable up to 90°C .
2. PH: 6.0-7.0, Optimum PH 6.0. It is deactivated at below pH5.0.
3. Ca 2 +: required.
Specification:
1. Solid type: 2000, 3000, 3500, 4000u/g. Premium grade: 4000u/g, 6000u/g, 8000u/g, and 10000u/g. Liquid type: 1500, 2000, 2500, 3000u/ml,4000u/ml
2. Unit definition : The amount of enzyme needed to hydrolyze 1mg of starch in one hour at pH6.0, 60 °C .
Application Guide:
1. Starch sugar and gourmet powder: Concentration of starch syrup 16-17B , pH 6.2-6.4 , CaCl2 0.2%, add the enzyme in the rate of 6-8U/g, stir and heat to 85-90°C, keep for 30 minutes.
2. In brewing of beer, add the enzyme in the rate of 6U/g, keep at 85-90°C for 30 minutes.
3. In textile desizing, add the enzyme in the rate of 0.2%(2000u/g), keep at 50-80 °C for 20-40 minutes.
4. Others: Rate of use is generally 6-8U/g, Ca 2 + concentration 150ppm.
Package and Storage
Plastic weave bag is used in solid type, 20kg/bag: Plastic drum is used in liquid type, 25kg/drum. It shall be kept in a cool dry place. Avoid direct sunlight.
