Introduction
Cellulase Powder (beta 1, 4-4 - dextran glucan - hydrolysis enzyme) is the floorboard of the degradation of cellulose to generate a group of enzymes that glucose, it is not a single enzyme, but the synergy of multicomponent enzyme system, is a kind of compound enzyme, is mainly composed of circumscribed beta glucan enzymes, cut inside beta glucan and beta - glycosidase enzymes, etc, and high activity of xylanase. It acts on cellulose and products derived from cellulose. Microbial cellulase plays an important role in transforming insoluble cellulose into glucose and destroying cell wall in fruit and vegetable juice to improve fruit juice yield.
