以甲壳素的白度为指标，研究了南极磷虾甲壳素的脱色条件，通过对比实验，确定H2 O2为脱色剂；通过单因素试验和正交试验，确定最佳脱色工艺条件为：H2 O2浓度12％，脱色温度65℃，脱色时间3 h，pH＝8～9，在该条件下，南极磷虾甲壳素脱色后的白度可达到70．

The decolorization conditions of chitin from Antarctic krill shells were studied.According to the comparative experiment,H2 O2 was defined as the decolorant.Through single-factor and orthogonal experi-ment,the optimum decolorization conditions of chitin from Antarctic krill were as follows:the concentration of H2 O2 was 1 2%,the decolorization temperature was 65 ℃,processing time was 3 h 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.
