Extraction and Characterization of Chitin and Chitosan from Invasive Alien Swimming Crab Charybdis longicollis

Chitosan is a biocompatible, biodegradable, non-toxic, antibacterial, antioxidant, and antifungal natural polymer. In this study, chitin chitosan were chemically isolated from the exoskeleton of invasive swimming crab Charybdis longicollis. order to obtain chitin, demineralization, deproteinization, decolourization steps applied samples. was prepared by deacetylation at high temperatures. The chemical composition C. longicollis characterized XRD FTIR analysis. yield extraction dry shells 25.78 %. produced extracted 80.23 experimental analyses revealed that obtained could be used as biomaterial.
