Product Description
This product is produced by submerged fermentation of Aspergillus niger followed by purification and formulation. The pectinase has high activity in the acidic pH range (pH 3.3-4.0).
Mechanism and Product Standard
Different types of pectinases (PG, PE, and PL) are involved in the product to ensure its efficient degradation of pectin. Besides, cellulase and hemi-cellulase in it help the removal of side chains in the pectin backbone, and will depolymerize pectin to the largest extent, which is very helpful for juice clarification and disintegration of plant cells releasing valuable components into juice.

Application
- Fruit and vegetable processing: juice yield increase and juice clarification; viscosity reduction for puree or fruit powder when necessary.
- Plant extract: more yield of target components, smoother.
- Wine/cider: higher yield, more color extraction and better wine clarification or stabilization.
- Beverage: transparency and stability improvement.
Dosage: The recommended dosage is 0.02-0.1 kg/t DS. 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.
Safety
Enzyme preparations are proteins that may induce sensitization and cause allergic-type symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes, or nasal mucosa. Any direct contact with the human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
Storage
Package: 1 kg / bag.
Storage: Keep sealed in a dry and cool place and avoid direct sunlight. Slight sedimentation is acceptable since it will not impact the performance of the product.
