摘要
[目的]研究蔬菜农药残留快速检测的方法,为保障果蔬类农产品的质量安全提供技术支撑.[方法]以六大类300份蔬菜样品的检测结果为依据,对速测卡法和酶抑制率法2种快速检测方法中的检测原理、检测步骤、检测结果、检出限、阳性结果符合率进行对比研究.[结果]速测卡法和酶抑制率法都属于快速检测农药残留的方法,相比较气相色谱法方便简单.速测卡法便于携带,随用随取,检测速度更快.酶抑制率法需要使用RP-410型农残速测仪或其他类型分光光度计、恒温培养箱等设备.[结论]速测卡法易操作,无需仪器和试剂,是市场、车站等场所快速检测蔬菜农药残留的较好方法.
Abstract
[Objective] The aim was to study rapid detection method for pesticide residues in vegetables,and provide technical support for ensuring quality and safety of fruits and vegetables.[Method] Based on the detection results of 300 vegetable samples in 6 major categories,testing principle,procedures,results,detection limit,coincidence rate of positive results of measurement card method and enzyme inhibition method were comparatively studied.[Result] The measurement card method and enzyme inhibition method both are rapid detection methods of pesticide residues,they are convenient and simple compared with the gas chromatography method.The measurement card method is easy to carry,with the use of access,the detection rate is faster.The enzyme inhibition method requires the use of RP-410 type rapid test instrument or other type spectrophotometer,constant temperature incubator and other equipments.[Conclusion] The measurement card method is easy to operate,without of instruments and reagents and is a good way to detect pesticide residues in vegetables from market,station and so on.
