摘　　要：研究了辐照处理对混浊苹果汁的品质和降解有机磷农药(毒死蜱、敌敌畏、乙酰甲胺磷、氧化乐果)的作用,并对果汁颜色、V C含量和总酚含量等的变化进行了研究。有机磷农药的测定参考农业部标准(NY/Y761-2004),并略作改进。结果表明,辐照降解有机磷农药效果较好,降解率从大到小依次为毒死蜱、敌敌畏、乙酰甲胺磷、氧化乐果。辐照剂量小于6kGy时对混浊苹果汁品质无显著负面影响。This experiment studied the influences of irradiation treatment of four kinds of organophosphorus pesticides（chlorpyrifos, dichlorvos, dichlorvos, acepgate and omethoate）degradation and the quality of cloudy apple juice, and studied fruit juice colors,Vc content,total phenol content and so on.Organophosphorus pesticides was measured according to the ministry of agriculture standards （NY/Y？6]-2004）, which was slightly improved. The results showed that under the radiation condition of these experiment, the degradation rate of four kinds pesticides organophosphorus descending order was chlorpyrifos, dichlorvos,acephate and omethoate.ln general, the effect of irradiation degradation, which had no negative effect on the quality of cloudy apple juice when the amount of irradiation was below 6kGY,on four kinds of organophosphorus pesticide was better.
