文摘

Chitin was extracted from four different local sources: the shrimp (Penaeus monodon), the desert locust (Schistocerca gregaria), the honey bee (Apis mellifera) and the beetles (Calosoma rugosa). Chitosan was then obtained by deacetylation of chitin and physicochemically characterized using the Fourier transform infrared (FTIR) and X-ray diffraction. The moisture content, water binding capacity, fats binding capacity, ash content were determined and chitosans morphology was visualized using the scanning electron microscope (SEM). The difference between the obtained chitosans from three insect sources and α-chitosan from shrimp in terms of crystallinity, fibrous structure was discussed.
