【摘要】 通过正交实验对利用鸭毛酸水解生产复合氨基酸的水解条件及水解液的脱色条件进行了研究。结果表明：盐酸浓度为6mol/L，固液为1/3，水解时间为12小时，其水解率可达58%。水解液脱色最佳条件为：脱色温度80℃，活性炭用量9%，脱色时间50min。更多还原

【Abstract】 Acid-hydrolysis and hydrolysate decolorized conditions for compound amino-acids production from duck feather are studied by using orthogonal tests. The experiment result shows that the optimum hydrolysis conditions are a ration of solid to liquid 1/3, a concentration of sulfuric acid 6mol/L, hydrolysising for 12h, compound amino-acids yield rate of 58%.The optimum hydrolysate decolorized conditions are decolorized temperature 80℃, carbon quantity 9%, decolourizing for 50min.更多还原
