Pullulanase, 2,000 u/ml 
Catalog Number IE-1130
Physical Form Liquid
Color Light brown
Declared Activity 2,000 u/ml
| Description | This product is produced by submerged fermentation of Bacillus subtilis followed by purification and formulation. It is a thermal stable debranching enzyme able to work at low pH, and is widely used in brewing, starch sugar processing, monosodium glutamate and alcohol fermentation, etc. |
| Mechanism | Pullulanase is a type of isoamylase which can selectively hydrolyze α-1,6-glucosidic linkage in pullulan, starch and oligosaccharides, thereby, making the complete hydrolysis of branched starch possible. Together with other enzymes (glucoamylase, β-Amylase) it speeds up saccharification and increase glucose or maltose yield. |
| Dosage |
Glucose production: The recommended dosage is 0.35-0.6 L per ton of dry starch together with glucoamylase together in saccharification step. Maltose syrup: The recommended dosage is 1-2 L per ton of dry starch together with Fungal Alpha-Amylase can together use in saccharification step. In brewhouse: The recommended dosage is 0.4-0.8 L of the enzyme preparation per ton of total raw materials. It's used for degradation of amylopectin and production of dry beer. 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. |
