Abstract
The decolorization conditions of chitin from Antarctic krill shells were studied.According to the comparative experiment,H2O2 was defined as the decolorant.Through single-factor and orthogonal experiment,the optimum decolorization conditions of chitin from Antarctic krill were as follows:the concentration of H2O2 was 12%,the decolorization temperature was 65℃,processing time was 3h and pH was in 8~9.The proven experiment showed that whiteness after decolorization of chitin from Antarctic krill shells could reach above 70 under this condition.
