工作原理

根据有机磷和氨基甲酸酯类农药能抑制昆虫中枢和周围神经系统中乙酰胆碱酶的活性，造成神经传导介质乙酰胆碱的积累，影响正常传导，使昆虫中毒死亡这一昆虫毒理学原理，用在对农药残留的检测中。

如果蔬菜的提取液中不含有机磷或氨基甲酸酯类农药或残留量较低，酶的活性不被抑制，试验中加入的底物就被酶水解，水解产物与加入的显色剂反应产生颜色。

反之，如果蔬菜的提取液中含有一定量的有机磷或氨基甲酸酯类农药酶的活性就被抑制或部分被抑制，试验中加入的底物就不能被酶水解或少部分被水解，从而不显色或颜色变化很小，用分光光度计测定吸光值随时间的变化情况计算出抑制率，就可以判断蔬菜中中含有机磷或氨基甲酸酯类农药的残留情况。
