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

Servet Ahmet Doğdu*, Cemal Turan and Tolga Depci


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