Production of Chitosan from Shrimp Shell

Shrimp Shell waste was obtained from a commercial shrimp shell processor dried in the sun for a period of 24 hours or longer until completely dried Shells are obtained. The dried shrimp shell were dematerialized with hydrochloric acid at ambient temperature with a solid to solvent ratio of 1:15(w/v) in an acid resistant vessel with stirrer for some hours until demineralization was completed. The dematerialized shells were deproteinised with sodium hydroxide solution for some hours with constant stirring at a solid to solvent ratio of 1:10 (w/v).Samples were than filtered and dried. Then deactelated at ambient temperature with conc. sodium hydroxide solution with a solid solvent for 48-72 hours until deactilation completed. The resulting chitosans were washed to neutrality in running tap water rinsed with distilled water filtered and dried for 24 hours. The resultant chitosan is typically deactilated and this chitosan is most soluble in solutions having a pH below 6.5. It gives yield about in the range of 75 to 80 percent from chitin
