DESCRIPTION
The pectinase is specially developed for the
clarification of pear juice. It’s made from finely selected microbial strain by
submerged fermentation followed by purification and formulation. The enzyme
preparation is capable of degrading pectin and other viscous substances in pear
juice, reducing juice viscosity, and promoting the precipitation of insoluble
fiber and polyphenol.
MECHANISM
Not very high in pectin content in pear, but
the polyphenol-rich stone cells and other viscous polysaccharides in pear make
it even more difficult to clarify pear juice. The present product has been
formulated with more relevant activities to degrade these viscous substances
besides pectinase. It has shown excellent clarification performance during pear
juice processing.
REACTION PARAMETERS
Optimal temp.: 52+2℃
Effective pH:3.5-5.5
Treatment time: 50-90 min
BENEFITS
1. Degrade pectin and turbidity substances in
juice;
2. Promote the precipitation of insolubles in
juice;
3. Increase shelf-life stability of juice
concentrate and avoid haze formation.
PRODUCT STANDARD
The product complies with GB1886.174.
