Abstract

This study aims to determine the isolation and characterization of chitosan from the skin of coconut crabs. Isolation of chitosan from coconut crabs was carried out through four stages, namely deproteination (4% NaOH, 80oC), demineralization (HCl 1.25 N, 70oC), depigmentation (4% NaOCl, 75oC), deasitilation (50% NaOH, 80oC). The degree of deasitilation of chitosan from walnut crabs is 82.52%. Chitosan FTIR spectrum analysis results of several main examples of wave numbers 3371.57 cm-1 which show symmetrical stretching vibrations due to overlapping OH and amines (NH), stretching vibrations of 1597.06 cm-1 caused by propagation of C=O and stretch vibrations 1651.07 cm-1 which shows secondary amide. Characterization of FTIR spectroscopy which showed the extraction of coconut crabs was chitosan.
