摘　　要：为研究电生功能水联合超声波清洗对马铃薯净菜中农药残留的去除效果,对采用不同切割方式的马铃薯净菜进行腐霉利、甲拌磷、百菌清和毒死蜱混合模拟污染,通过QuEChERS前处理方法结合气相色谱-质谱联用法(GC-MS)进行检测,得到酸性电生功能水(AcEW)-超声波清洗处理对马铃薯净菜中4种农药残留的去除率,探讨不同清洗液、样液比、超声波功率与清洗时间对农药残留去除效果的影响规律。结果表明:马铃薯净菜的适宜清洗液为AcEW;不同料液比条件下农药残留去除效果无显著差异(P>0.05);超声波功率和清洗时间对农药残留的去除影响显著(P<0.05)。马铃薯丝、条、片、丁的最佳清洗功率分别为200、400、400和400 W,在此条件下,马铃薯丝、条、片、丁中毒死蜱和甲拌磷的平均农药残留去除率分别为78.79%、75.05%、70.56%和68.46%,腐霉利和百菌清的平均农药残留去除率分别为45.96%、45.91%、37.5%和36.92%。适宜的清洗时间分别为10、10、20和20 min,在此条件下,马铃薯丝、条、片、丁中毒死蜱和甲拌磷的平均农药残留去除率分别为78.03%、75.52%、71.85%和69.18%,腐霉利和百菌清的平均农药残留去除率分别为47.27%、45.05%、40.65%和41.33%。本研究所获得的酸性电生功能水-超声波清洗去除马铃薯净菜中农药残留的影响规律,为提高马铃薯净菜加工清洗环节的农药残留控制水平提供理论和技术支持。In order to study the removal effect of pesticide residues in fresh-cut potatoes by electrolyzed functional water combined with ultrasonic cleaning,the simulating pollution of procymidone,phorate,chlorothalonil and chlorpyrifos in fresh-cut potatoes with different cutting methods was carried out.After the detection of these samples by gas chromatography-mass spectrometry(GC-MS),the removal rates of four pesticide residues in fresh-cut potatoes treated with acid electrolyzed functional water(AcEW)-ultrasonic cleaning were obtained.The effects of washing solution,the ratio of sample to washing solution,ultrasonic power and washing time on pesticide removal rates were investigated.The results showed that the suitable washing solution for fresh-cut potato was AcEW;there was no significant difference(P>0.05) on pesticide removal rates under the conditions of different ratios of sample to washing solution.The optimal ultrasonic power of potato strip,chips,slices and diced potato were 200,400,400 and 400 W,respectively.Under these conditions,the mean removal rate of chlorpyrifos and phorate were 78.79%,75.05%,70.56% and 68.46%,respectively;and the mean removal rate of procymidone and chlorothalonil were 45.96%,45.91%,37.5% and 36.92%,respectively.And the optimal washing time of them were 10,10,20 and 20 minutes,respectively.Under these conditions,the mean removal rate of chlorpyrifos and phorate were 78.03%,75.52%,71.85% and 69.18%,respectively;and the mean removal rate of procymidone and chlorothalonil were 47.27%,45.05%,40.65% and 41.33%,respectively.The results obtained in this study provide theoretical and technical support for improving the pesticide residue control levels in cleaning process of fresh-cut potato.
