The bycatch resources of crustaceans were taken from Royapuram Fish Landing Centre, Kasimedu, Chennai. The stomatopod - Harpiosquilla gonyptes and shrimps - Panapenaeopsis maxillipedo and Penaeus indicus were collected and chitin was extracted from the shells of the crustacean samples. The chitin further used for the production of glucasomaine hydrochloride. The glucasoamine hydrochloride was derived from the chitin by acid hydrolysis. The samples were confirmed through FT-IR spectrum against standard glucosamine hydrochloride.The stomatopod H. gonyptes shows the peaks at 3676 cm-1, 3404cm-1, 2848 cm-1, 1629 cm-1 and 1012 cm-1. The P. maxillipedo shows the peaks at 3712 cm-1, 3408 cm-1, 2370 cm-1, 1629 cm-1, 1095 cm-1 and 1033 cm-1. Whereas the peaks through FT-IR of the shrimp P. indicus shows 3676 cm-1, 3404 cm-1, 2372 cm-1, 1641 cm-1 and 1186 cm-1.In the present study the intense bands were observed 3400 cm-1 (H. gonyptes), 3408 cm-1 (P. maxillipedo) and 3404 cm-1 (P. indicus) which reveals that association of O-H and N-H stretching. The peaks at 1629 cm-1 (H. gonyptes), 1629 cm-1 (P. maxillipedo) and 1641 cm-1 (P indicus) which reveals that association of NH2. Whereas the peaks at 1012 cm-1 (H. gonyptes), 1095 cm-1 & 1033 cm-1 (P. maxillipedo) and 1186 cm-1 (P. indicus) which reveals that association of secondary alcohol -OH. All the above peaks levels were confirm that samples were glucosamine hydrochloride. The present study was found as simple, efficient and suitable for the preparation of glucasoamine from crustacean shells thereby recycling crustacean wastes.
