Abstract

This study presents the first ever data of extracting CHITIN from the CHITON shell, which was 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 %), protein (5.2%), and CHITIN (4.3 %). Due to the results of element analysis and 1H NMR, the final degree of de acetylation of CHITOSAN was 90%. Surprisingly, a significant amount of Fe was accidentally found in the shell after demineralization, and removed from the solution through the filtering. Nonetheless, remained Fe in the extracted CHITIN and CHITOSAN was 20 times higher than those previously reported from the shell of shrimps and crabs. Presence of this amount of Fe could describe why the produced CHITOSAN was darker compared to the commercial CHITOSAN. ANTIOXIDANT activity tests showed that the IC50 of the extracted CHITOSAN was higher than one estimated for the commercial CHITOSAN. ANTIOXIDANT activity of the extracted CHITOSAN is even better than the commercial version and may be used in pharmaceutical industry as a source of ANTIOXIDANT.
