摘  要：
研究了超声波-TiO2催化去除苹果汁中拟除虫菊酯类农药残留的作用效果和机理,对比分析了处理前后苹果汁品质变化。采用响应曲面法优化催化去除苹果汁中拟除虫菊酯类农药残留的最佳工艺参数为:TiO2质量浓度0.5 g/L、超声波功率416 W、时间18 min、温度37℃,在此条件下,催化去除率可达到62.17%;超声波-TiO2处理对苹果汁理化指标没有显著影响,经过处理后的苹果汁符合出口的相关标准。

摘  要：
The catalytic removal function and mechanism of ultrasonic treatment coupling with TiO2 on pyrethroid pesticides in apple juice were investigated,the main quality change of apple juice and mechanism of catalytic removal were researched.The response surface method was applied to optimize the process parameters and the results were as follows: the TiO2 amount was 0.5g/L,the ultrasonic power was 416W,the treatment time was 18min,the ultrasonic temperature was 37℃.Under this condition,the removal rate would reach to 62.17%.The main chemical and physical indexes of apple juice processed by ultrasonic treatment coupling with TiO2 have no significant change,all accord with the export standards of apple juice.
