Shelf-Life Specific Moisture Variation In Chitosan Of Genus Fenneropenaeus Distributed Along Arabian Sea, India

Chitosan is a characteristic polysaccharide, naturally extracted from the crustaceans shells. The stability and shelf-life of chitosan are affected by a few parameters, basically the moisture content. In this study, three species of shrimps such as Indian white shrimp (Fenneropenaeus indicus), banana shrimp (F. merguensis), and tiger prawn (F. monodon) were utilized for the extraction of chitosan. The extraction strategy included the method of demineralization, deproteinization, and deacetylation. Later the yield and moisture of chitosan were examined from three diverse species. The yield of shell waste ranged between 46% to 50% (on moist weight premise) and the chitosan was between 18.0 to 20.2%. Moisture content always plays a critical part in chitosan shelf life and stability and was between 5.2% to 6.8 %.
