Chitin is the second most abundant natural polysaccharide after cellulose and is present in the crustacean exoskeleton like crab, shrimp, insects and fungi. It is the main structural component of the exoskeletons of the animals like insects and crustaceans. Crab, shrimp, squilla and fish scale waste is ideal raw material for chitin production. The present work is aimed at extraction,characterization and dye adsorption ability of chitin from crab shells. The methodology include acid hydrolysis, demineralization followed by deproteinization step. The chitin produced is analysed by FTIR based on the interpretation of the spectrogram of the two samples of chitin synthesized in the present work, it can be said that all functional groups expected are seen. The applications of the chitin are numerous but the study is focused on dye adsorption ability.
