Product Description
The low-temperature α-amylase [EC 3.2.1.1] is produced by submerged fermentation of Bacillus subtilis followed by purification and formulation.
This product belongs to the family of hydrolytic enzymes, attacking α-1.4 glycosidic bond in starch in a random but efficient way, producing dextrin, oligosaccharides, and a small amount of glucose. α-Amylase is faster-acting than β-amylase and is one of the major digestive enzymes with an optimum pH of 6.0.

| Odour | Slight fermentation odour |
| Activity | 1,500u/g ~ 3,000u/g |
Dosage
Dilute the product before use. The product is calcium dependent. Ca2+ improves the stability of the enzyme and makes it more resistant to pH.
