α-Amylase

DESCRIPTION

Derived from fermentation products of Bacillus subtilis, Angel α-amylase is used to hydrolyze preferentially a -1,4 linkages in short chain oligosaccharides produced by the action of other enzymes on amylose and amylopectin e.g. α-glucosidases.

MECHANISM

  • supplement the deficiency of endogenous enzyme during weaning period.
  • Improve the utilization of grain starch.
  • Reduce environmental pollution by increasing the absorption of nutrient.

APPLICATIONS

6-8U per one gram of material

  1.  Beer industry
    6 U per one gram of material
  2. Used in the desizing of textile
    Dosage is about 0.2% ( 2000U/g ), at 60℃-80℃20-40min.
  3. Other Industries
    6-8U of enzyme activity units/1g of starch, The concentration of calcium ion is 150ppm.

USAGE

Feed additives: Recommended dosage is 25-50g ofα-amylase(2000U/g) per ton of complete feed. The product should be well mixed with feedstuff.
