Description:
Thermal Stable Alpha Amylase with excellent heat resistance .it is widely used in the industries of starch sugar (glucose, maltose, dextrin, fructose, oligosaccharide), alcohol, beer, monosodium glutamate, brewing, organic acid, textile, print, dyeing, papermaking and other Fermentation industries, 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. Oligosaccharides, glucose and maltose are also produced.
Properties:
1. Optimum temperature: above 90°C, e.g. 95-97°C. At 100°C , the enzyme still retains activity.
2. PH: 5.5-8.0, optimum PH 5.8 -6.5
3. Ca2+: 50-70ppm required.
Specification:
1. Liquid type:10000 u/ml, 20000 u/ml, 30000 u/ml, 40000u/ml until 190000u/ml.
Solid type:,20000u/g, 40000u/g until 230000u/g
2. Unit definition: The amount of enzyme needed to hydrolyze 1mg of starch in one minute at pH6.0, 70 °C.
Application Guide:
1. In brewing of beer, add the enzyme in one batch in the rate of 0.3 litre for 20000 u/ml, raise the temperature to 95-97°C, keep for 30 minutes.
2. In manufacture of alcohol, add the enzyme in the rate of 0.3 litre for 20000 u/ml at pH6.5-7.0, stir and raise the temperature to 100 ± 5 °C, keep for 100 minutes.
3. In manufacture of starch sugar or gourmet powder, add the enzyme in the rate of 12MU/t at pH6.0-6.5, raise the temperature to 100 ± 5 °C, keep for 30 minutes at 95-100°C or 60-120 minutes at 95°C if steam (105°C ) injection method is used.
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.
