Chitosan 90% HD

Chitosan 90% HD is a high-density grade of chitosan, a natural polysaccharide obtained by deacetylating chitin from the shells of shrimp and crab. The grade name refers to its degree of deacetylation, listed in the specification and to its high bulk density. Nustras supplies it as a white to light-yellow free-flowing powder.

Chitosan is formulated into capsules and tablets for dietary-fibre supplements, into fibre blends, functional foods and beverages, into cosmetics as a film-former, into agricultural seed and crop products, and into water clarification.

The material is a white to light-yellow, free-flowing powder, insoluble in water but soluble in dilute acids. Degree of deacetylation is confirmed by titration or spectroscopy against the specification; viscosity, loss on drying, ash, insoluble matter, heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis. Chitosan is labelled as a shellfish-derived ingredient.

Nustras supplies Chitosan 90% HD in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Chitosan is an accepted supplement ingredient in major markets; buyers confirm the permitted level, allergen labelling and claim for their application.
