Character 

Chitosan  It is extracted from chitin, insoluble in water but soluble in dilute acid 

and absorbed by human body. As the first derivate, it's chemical constitution is 

macromolecule alkalescent Polysaccharide polymer with cation. It has peculiar

physical, chemical properties and bioactive function. 

Application

Chitosan  It can mostly be applied in the following industries: textile , dyeing and 

printing, leather, tobacco, plastics, food additive, fodder, pharmaceutics, color film, 

paper manufacturing, biological engineering, agriculture protecting and dispose 

waste water etc, or widely used in health food and food additives
