PECTIN LYASE,China price supplier

Introduction

Pectin lyases is made from Aspergillus niger through cultivation, fementation and extraction technique, which is in conformity with FCC..It is used in pectin degradation processes. It work on fifth β-carbon atom of galacturonic acid by β-racemization method, which transfer H ofβ-carbon atom to Oxygen atom of glucosidic bond. In this way, glucosidic bond break , and form double bond between C4 and C5 of galacturonic acid which produce galacturonic acid oligosaccharide。

This product is manufactured in accord with the standards of FDA, WHO and UECFA..

definition of unit

1 unit of Pectin lyase equals to the amount of enzyme which work on pectin to get 1µmol double bond at 30℃ and pH5.2 in 1min.

Action Principle

It work on fifth β-carbon atom of galacturonic acid by β-racemization method, which transfer H ofβ-carbon atom to Oxygen atom of glucosidic bond. In this way, glucosidic bond break , and form double bond between C4 and C5 of galacturonic acid which produce galacturonic acid oligosaccharide。

Efficacy

It can be used in clarification of fruit and vegetable juices, fruit wine

It can be used in feed to remove pectin anti nutritional factors.

It can be used in hemp degumming in acidic conditions.

Safety

Enzyme preparations belong to protein, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
