OBJECTIVE: Decolorization of crude chitin from Catharsius molossus was studied in order to prepare chitosan with white color and high viscosity.
METHODS: Some factors affecting decolorization such as the kind of decolorant reagent, H2O2 concentration, pH, solid-liquid ratio, temperature and other factors were studied by single factor test and orthogonal design.
RESULTS: The best decolorization process of chitin from Catharsius molossus was as follows:treated with 15 times of 15% H2O2 at 45 degrees C.
CONCLUSION: The process is stable and feasible. The chitosan from Catharsius molossus might be used as a new carrier of colon-specific drug delivery system.
