If the vegetable extract does not contain organophosphorus or carbamate pesticides or the residue is low, and the enzyme activity is not inhibited, the substrate added in the test will be hydrolyzed by the enzyme, and the hydrolysate will react with the added developer to produce color. Otherwise, if the vegetable extract contains a certain amount of organic phosphorus or carbamate pesticide enzyme activity, it will be inhibited or partially inhibited, and the substrate added in the test will not be hydrolyzed by the enzyme or a small part will be hydrolyzed, so there will be no color development or little color change. Use a spectrophotometer to measure the change of absorbance value with time to calculate the inhibition rate, We can judge the residue of organophosphorus or carbamate pesticides in vegetables.
