火麻蛋白脱色研究

摘要

Hemp protein were used as raw material to study on decolorization of hemp protein processed by dif-ferent decoloring agent(organic reagents,activated carbon).On the basis of single factor test,borthogonal ex-periments was applied to optimize the extraction parameters of active carbon powder,adsorption time and decol-orization temperature.The results indicated that the optimum decolorization effect was obtained from the treat-ment conditions of 3 % active carbon powder under conditions of decolorization temperature 50℃and adsorp-tion time 60 min.The hemp protein brightness value reached 71.8 and the recovery rate of hemp protein was up to 91.45 %.%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 %.
