Chitosan Oligosaccharide

Specification of Chitosan Oligosaccharide Chitosan Oligosaccharide is obtained by an enzymatic hydrolysis of chitosan using chitosanase. Chitosan oligosaccharides is a non-toxic, functional amino sugar of lowmolecular weight. The food grade chitosan oligo saccharides is highly purified and is suitable for both medical and food applications.
