摘　　要：为探索高效快速降解果蔬中残留农药的新方法,该文利用等离子体处理含有氧化乐果的大白菜和苹果,研究了等离子体处理对其中氧化乐果残留的降解效果及其影响因素。结果表明,等离子体对其中残留的氧化乐果降解有明显效果,1.5min内可使氧化乐果降解95%以上,且对大白菜中残留的氧化乐果降解效果优于苹果中的;等离子体降解氧化乐果的同时对其品质几乎无影响,色差值和Vc含量与对照基本一致。To obtain a new method of pesticide residue degradation in fruits and vegetables,the effect and influence factors of omethoate residue degradation Chinese cabbage and apple were studied by using plasma.The results showed that plasma had an excellent effect on omethoate residue-degraded in Chinese cabbage and apple.The omethoate could be degraded by over 95%within 1.5 minutes.Besides,the effect of plasma on omethoate residue degradation in Chinese cabbage was superior to that in apple.As color difference and Vc quantity in samples processed by plasma were the same as in control group,it was concluded that omethoate residue by using plasma had no passive effect on the characters of fruits and vegetables.
