Evaluation of Fluorescence Probe for Rapid Detection of Pesticide Residues in Fruits and Vegetables
Objective:To evaluate the performance of fluorescent probe for rapid detection of pesticide residues in fruits and vegetables.Method:The detection limit of fluorescent probe reagent for rapid detection of pesticide residues in fruits and vegetables was determined by fitting standard curve,and the accuracy,repeatability,stability and consistency of the results of instrument confirmation method were evaluated.Result:In the range of 3.753～107.180 μg·kg-1,the method had a good linear relationship,and the detection limit was 5.068 μg·kg-1,and the recovery was 85.12%～95.47%.Compared with the results of the instrument confirmation method,the deviation of the results of the rapid detection of pesticide residues by fluorescence probe was-1%～17%.Conclusion:This paper provides an accurate,rapid and convenient fluorescence probe method for the rapid detection of pesticide residues in fruits and vegetables.
