摘　　要：以火麻蛋白为原料,开展不同脱色剂(有机试剂、粉末活性炭)对火麻蛋白脱色研究,在单因素试验的基础上,采用正交试验对活性炭用量、吸附时间、脱色温度3个因素进行优化。确定火麻蛋白脱色的适宜条件为:活性炭用量为3%,脱色温度为50℃,吸附时间为60 min,在此脱色条件下,火麻蛋白亮度值L达到71.8,蛋白回收率为91.45%。Hemp protein were used as raw material to study on decolorization of hemp protein processed by different decoloring agent(organic reagents,activated carbon).On the basis of single factor test,borthogonal experiments was applied to optimize the extraction parameters of active carbon powder,adsorption time and decolorization temperature.The results indicated that the optimum decolorization effect was obtained from the treatment conditions of3%active carbon powder under conditions of decolorization temperature50℃and adsorption time60min.The hemp protein brightness value reached71.8and the recovery rate of hemp protein was up to91.45%.
