Low Temperature α-amylase, 40,000 u/ml 
Catalog Number IE-1126
Physical Form Liquid
Color Brown
Declared Activity 40,000 u/ml
| Description | Low-temperature α-amylase, 40,000 u/ml is produced by submerged fermentation of Bacillus subtilis followed by purification and formulation. The product is not as heat-stable as thermostable α-amylase, bringing the benefit of easy inactivation. |
| Mechanism | This product belongs to family of hydrolytic enzyme, attacking α-1.4 glycosidic bond in starch, glycogen, etc., producing dextrin, oligosaccharides a small amount of glucose. |
| Dosage |
Brewing industry: The recommended dosage is 0.4-0.8 L of the enzyme preparation per ton of total raw materials, added at liquefaction. For alcohol industry: Add 0.4-1 L per ton of total raw materials with pH 5.0-6.0. Fruit juice industry: The recommended dosage is 0.02-0.1 L/T fruit. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume. |
