Abstract

Nowadays the production of Chitin and Chitosan are developed in a commercial scale. More than billion tons of Chitosan are manufactured each year from the shells of crabs and shrimps. Chitosan are recognized as beneficial materials that are non-toxicity, good biodegradability, universal biocompatibility and having a good resistance in the term of antimicrobial activity. Keeping the importance of chitin and Chitosan in mind, an attempt has been made on the extraction of Chitin from the shell and conversion of Chitin into Chitosan through deacetylation. The Chitin was prepared from shell and operculum of Penaeus Monodon or Tiger Shrimp (by demineralization and deproteinization) and Chitosan by the deacetylation of Chitin. The results of the present study pave the way and provide the baseline information for the utilization of Chitosan in the development of biomedical application. The resulted Chitosan flakes will be milled into powder using Planetary Ball Milling equipment with different rotational speed. Several material characterization method will be done to examine the morphology, structure and composition in the term of physically after the synthesis and extraction of the Chitosan have been done such as; Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX), X-ray Diffraction (XRD), Particle Size Analyzer (PSA) dan Fourier Transform Infrared Spectrometry (FT-IR).
