Food grade pectin lyase enzyme for juice

 PRODUCT DESCRIPTION

This product is produced by submerged fermentation of Aspergillus niger followed by purification and formulation. It belongs to the pectinase family and can break down esterified pectin. 

MECHANISM

Pectate lyase is capable of pectin depolymerization by eliminative cleavage of pectin at their non-reducing ends, yielding oligosaccharides with 4-deoxy-α-D-mann-4-enuronosyl groups.

 

APPLICATIONS

l  Fruit and vegetable processing: Used as mashing enzyme to increase juice yield, reduce the viscosity of mash and juice to ease downstream processing; reduces viscosity of puree and avoid gelling problem during concentration.

l  Plant extract: Disintegrates plant cell to liberate target component and smooth operation during extraction and purification, and improves stability of liquid plant extract preparations.

l  Wine and cider: Improves juice and color yield and product shelf life stability.

 APPLICATION RECOMMENDATION

The recommended dosage is 0.05-0.2kg/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. 

SAFE HANDLING PRECAUTIONS

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor. 

WARNINGS

Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
