What is Glucoamylase Powermix 2.0?
The product is produced by mixing carefully optimized proportion of glucoamylase and pullulanase coming from submerged fermentation of Aspergillus niger and Bacillus subtilis, respectively. The combination of glucoamylase with supplementary pullulanase makes saccharification more efficient by avoiding limit dextrin and by-product formation, and therefore saving processing cost while producing more glucose.

Glucoamylase Powermix 2.0 Benefits
Efficient degradation of dextrins
• Higher dextrose yield (DX＞96%) and Less by-products formation
• Low treatment costs and dosages
Glucoamylase Powermix 2.0 Dosage
The recommended dosage is 0.35-0.6 kg of the enzyme preparation per ton of dry starch when saccharifying at 60-63℃ and pH 4.3-4.5. A starting dose of 0.45kg per ton of dry starch is recommended under most conditions. However, the optimal dosage depends on the specific process parameters and should be determined by testing different dosages.
Glucoamylase Powermix 2.0 Recommended Storage
| Best Before | When stored as recommended, the product is best used within 6 months from date of delivery |
| Shelf Life | 6 months at 25℃, activity remains≥90%; Increase dosage after shelf life. |

Safety and Handling Precautions
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
