Extraction, Physicochemical Characterization and In Vitro Antioxidative Potential of Chitosan in Shrimp Shell Waste from Beni Saf Sea, Algeria

Fatma Youcefi, Ali Riazi

Abstract: Chitin and its deacetylated derivative chitosan are natural polymers, they are oligosaccharides from exoskeleton, of crustaceans, insect shells and cell walls of fungi. The present study was undertaken to study the physiochemical parameters and the antioxidant activity from shrimp shell waste ; The intrinsic viscosity of chitosan with a molecular weight are 216440, 37 cps and 1, 718 x 106 0, 019 Da mol-1 respectively, the percent of Ash 0, 3450, 040 %, moisture is 2, 98 0, 13 %, and protein is 0.3 0, 041 %. The DPPH radical scavenging potential of chitosan ranged from 37.66 % to 62.66 % at varying concentrations (0.5 to 2 %) chitosan produced was also characterized with Fourier Transform Infrared Spectroscopy (FTIR).

Keywords: Shrimp shells, FTIR spectroscopy, molecular weight, deacetylation degree, antioxydant activity
