Detailed Product Description

The product is obtained by deep fermentation of Bacillus Subtilis. It is widely used in manufacture of starch sugar and alcohol, brewery, textile, dye & printing, papermaking, feed industry 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 ,operable up to 90 .

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, 

2. Unit definition : The amount of enzyme needed to hydrolyze 1mg of starch in one hour at pH6.0, 60 .

3. Standard :QB1805.1-93.

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 , keep for 30 minutes.

2. In brewing of beer, add the enzyme in the rate of 6U/g, keep at 85-90 for 30 minutes.

3. In textile desizing, add the enzyme in the rate of u/g, keep at 50-80 for 20-40 minutes.

4. Others: Rate of use is generally 6-8U/g, Ca ^{2 +} concentration 150ppm.
