Comparative Analysis of Rapid Detection Methods for Pesticide Residues in Fruits
This article aims to select a rapid detection method suitable for grassroots market supervision departments to monitor organic phosphorus pesticide residues in agricultural products such as fruits and vegetables.The detection limits of enzyme inhibition rate method and colloidal gold immunochromatography method were compared and verified,and the quantitative detection results of gas chromatography were used as the accuracy judgment basis.The results of the two rapid detection methods for detecting 30 batches of 10 types of vegetables,including cabbage,cucumber,and carrot,were evaluated.The results showed that the enzyme inhibition rate method has a high detection limit and is prone to false negatives and false positives.It is only suitable for detecting high-dose organic phosphorus and carbamate pesticide residues in fruits and vegetables.Colloidal gold immunochromatography has high sensitivity and is basically consistent with the detection results of gas chromatography.It can detect single pesticide residues,with simple operation and short detection time.It is suitable for grassroots market supervision departments to quickly detect pesticide residues in fruit and vegetable products.
