Pectinase
Description
Pectinase is a mixture of protopectinase, pectic acid hydrolase and pectinolytic enzymes which are obtained by aspergillus nigger fermentation. Under the effect of protopectinase, natural pectin turned into water soluble pectin; pectin is catalyzed by pectin methyl ester hydrolase to remove methyl groups,and generate pectic acid; pectic acid is degraded by pectic acid hydrolase and pectate lyase to generate galacturonic acid. This product is now widely used in feed, fruit wine processing, textile printing and dyeing, etc.

Functions
1.Destroy the cell walls, expose the cell contents, and improve the digestibility of the nutrients.
2.Effectively degrade pectin, reduce the viscosity of chyme and reduce the occurrence of diarrhea.
3.Effectively degrade pectin in feedstuff, promote the metabolism of protein and energy, and improve the rate of feed utilization.
4.Expand usable feed ingredients type, make full use of by-products such as cheap, unconventional feed resources, reduce the formula cost.
Dosage
Recommended dosage is 100-180g/t with 10000 U/g in complete feed.
