The Effect of Different Chemical and Physical Processing on the Physicochemical and Functional Characterization of Chitosan Extracted from Shrimp Waste Species of Indian White Shrimp

Abstract

The preparation and characterization of chitosan, water soluble polysaccharide, from waste of Indian white shrimp (penaeus indicus) are reported. The effect of different conditions of chemical and physical methods on extraction, physiochemical (proximate composition, solubility, degree of deacetylation and molecular weight) and functional properties (fat binding capacity, water binding capacity and color attributes) of biopolymer chitosan was examined. The results suggested that optimal condition preparation involves alkali concentration of 50%, a power of microwave of 720 W and a reaction time of 20 S. The end product had a white color, high degree of deacetylation, solubility and low molecular weight, ash, protein and moisture content.
