Benefits
- Efficient degradation of dextrins
- Higher dextrose yield (DX＞96%) and Less by-products formation
- Low treatment costs and dosages
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 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.
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. |
|
Storage Conditions |
