The product is a bacterial amylase preparation derived from Bacillus licheniformis extract. It has good tolerance to high temperature, can be widely used in manufacture of starch sugar and alcohol, brewery, textile, dye & printing, 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. Oligosaccharides, glucose and maltose are also produced.

Properties:

1. Optimum temperature : above 90 , e.g. 95-97 . At 100 , 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

  Solid type:,20000u/g, 40000u/g

2. Unit definition: The amount of enzyme needed to hydrolyze 1mg of starch in one minute at pH6.0, 70 .

3. Standard : QB/T2306-97

Application Guide:  

1. In brewing of beer, add the enzyme in one batch in the rate of 6MU/t, raise the temperature to 95-97 , keep for 30 minutes.

2. In manufacture of alcohol, add the enzyme in the rate of 6MU/t at pH6.5-7.0, stir and raise the temperature to 100 ± 5 , 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 , keep for 30 minutes at 95-100   or 60-120 minutes at 95   if steam (105 ) injection method is used.
