Food Grade Chitosan Powder CAS 9012-76-4 Vegan Low Molecular Weight 80 Mesh for Industrial Applications
CAS 9012-76-4 • Vegan • Low Molecular Weight • Plant-Derived
Chitosan is derived from shrimp and crab shell extracts, with chitin as the primary raw material. This natural polymer is widely found in crustacean shells and low plant fungi. After deacetylation processing, chitin transforms into chitosan powder suitable for multiple industrial applications.
