چکیده
The potential of chitin and its derivatives mainly chitosan extends to various existing and proposed applications in an unusually large number of fields. In the present study, the prospect for using the exoskeleton of cephalopods as a raw material for chitosan manufacture was tried out. This includes the extraction of chitin from the cuttlebone (by deproteinization and demineralization) and chitosan by deacetylating the chitin. The chitin yield was 24% in the cuttlebone of S. prashadi and the chitosan yield was 62.6% from the chitin. The FTIR spectrum of chitin and chitosan was also confirming the presence of chitin and chitosan in the resultant sample analyzed. The degree of acetylation of chitosan was calculated as 55.95% using the FTIR stretching bands. The yield was higher than that the crab shells and other sources. So the results of the present study throw more light on the study expanding the tentacles to find out other potential sources for the extraction of chitin and chitosan.

Three types of chitin as α (exoskeleton of crustaceans), β (cuttlebone of cephalopods) and γ (some fungal cell wall) exist in nature. Chitosan is the most important derivative of chitin, which has various biological activities. In this study, α, β and γ-chitosans were extracted from Portunus segnis exoskeleton, Sepia pharonis cuttlebone and Aspergillus niger ce...

Chitosan is a commercially available derivative of chitin that has been extensively studied for its antimicrobial properties. In order to improve the water solubility and its biological activity, the chemical modification or derivatisation is attempted. In the present investigation, the chitosan prepared from the cuttlebone of Sepia kobiensis was being chemically modified by reacting it with or...

Background and purpose: Chitin is one of the main components of crustaceans’ exoskeleton. Chitosan is produced by deacetylation of chitin. Molecular weight and degree of deacetylation play important roles in biological activity of chitin, chitosan, and their derivatives. So far, various derivatives of chitin and chitosan are obtained. The purpose of this study was to prepare derivatives o...

This study presents the first ever data of extracting chitin from the Chiton shell, which then converted to the soluble chitosan by soaking in the 45% NaOH solution. The obtained chitin and chitosan were characterized by the seven different methods. Antioxidant activity of the extracted chitosan was also evaluated using the two methods. The shell content was divided into calcium carbonate (90.5...
