Development of biodegradable polysaccharide by modified process from sea desecrates and its proximate analysis.

The manufacturing of natural, biodegradable polysaccharide from crustacean shells (prawns shrimp and crab shell) was carried out in the laboratory. The extraction was done by slight modification in the proposed method. This manufactured chitosan was compared with commercially available chitosan for its proximate analysis. Degree of deacetylation, Molecular weight and Nitrogen content of manufactured chitosan was determined and compared with the commercial chitosan. The structural interpretation was confirmed by the FTIR analysis. This manufactured chitosan is readily used for various industries such as textile, cosmetics, food and pharmaceutical applications. Also it shows as an antimicrobial activity and act as an effective pesticide in agricultural field. This developed chitosan show equivalent properties as that of commercial grade chitosan.
