Preparation and Preliminary Characterization of Chitosan from Catharsius molossus Discards

Abstract:

Preparation techniques of chitosan from Catharsius molossus L. processing discards were studied by orthogonal design. Preparation techniques were as follows:demineralizing: soaked for 30 min at 80 °C with 1.3 mol•L^-1 HCl, then kept for 12 h under room temperature. Deproteinization and delipidation: treated for 6 h at 90 °C with 4 mol•L-1 NaOH. Decolorizing: soaked at room temperature with 3% KMnO₄, then treated with 2% oxalic acid at 70 °C. Deacetylation: treated for 6 h at 110 °Cwith 14 mol•L^-1 NaOH. Properties of chitosan were characterized by Fourier transform infrared spectroscopy(FTIR), X-ray diffraction (XRD), etc. It proved the technique was stable and feasible. The result also preliminarily showed that chitosan from Catharsius molossus L. was better than shrimp’s. It will be widely applicated in biomedical and other industrial areas with such exiciting properties.
