摘　　要：介绍了可溶性米渣水解蛋白粉的制备工艺,重点叙述米渣水解蛋白粉的脱色研究。在单因素试验的基础上,进行L9(34)正交试验,最佳脱色条件是:对于5%的水解蛋白溶液20 mL,活性炭用量0.7g,pH 6.5,温度60℃,搅拌时间60 m in,脱色率达到84.2%。脱色后蛋白粉干爽,色白,有光泽。The preparation of soluble rice residue protein hydrolysate powder was described and the emphasis was on the decoloration. Through the L_9 （ 3^4 ） orthogonal experiment on the basis of single-factor experiment, the decoloration rate of rice residue protein was 84.2% under the optimum conditions ： protein hydrolysate of 5% 20mL, activated carbon dosage 0.7 g, pH 6.5, decoloring temperature 60℃, decoloring time 60 min. The powder was drytouch, white in color and had gloss.
