摘　　要：以橡胶籽为原料,采用正交试验和响应面设计等方法,对橡胶籽打浆液的脱毒工艺进行研究。第一种方法为煮沸脱毒,经煮沸时间的单因素试验后,确定脱毒的最优条件为:煮沸时间20 min。第二种方法为柠檬酸结合煮沸脱毒,经正交试验后确定脱毒的最优条件为:脱毒温度40℃,脱毒液的用量5倍于橡胶籽的质量,脱毒10 h,其间每2 h换一次脱毒液。第三种方法为β-葡萄糖苷酶结合煮沸脱毒,经响应面设计试验后确定脱毒的最优条件为:酶解温度45.1℃,加酶量15 U/400 mL,pH 6.15,酶解时间60 min。可脱除橡胶籽打浆液中99%以上的氰化物。Through single orthogonal experiment and the design of response surface method, study the detoxification process of removing cyanide from rubber seed＇s slurry. The first method for detoxification was boiling, after the single factor experiment of the boiling time get the optimal condition of removing cyanide for 20 min. The second method for detoxification was citric acid combined with boiling, after orthogonal test to determine the optimal condition was that treatment time for 10 h and in this process, changing the soak water every 2 h, soak temperature of 40 ℃, water addition 6 times of the rubber seed mess. The third method for detoxification was β-glucosidase combined with boiling, after the design of response surface method to determine the optimal condition was that treatment time for 60 min, soak temperature of 45.1 ℃, pH of 6.15 and the additive amount of β-glucosidase 15 U/400 mL. The actually maximum rate of detoxification in rubber seed＇s slurry will be reached to 99%.
