Dosage

The recommended dosage is 0.1-2kg of the enzyme preparation per ton of total raw materials. 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 12 months from date of delivery.

Storage at customer’s warehouse

0-25

Storage Conditions

Keep sealed in a dry and cool place and avoid direct sunlight. Slight sedimentation is acceptable since it will not impact performance of the product. Inappropriate storage may lead to inactivation of enzymes and higher dosage.
