Abstract

Abstract: To explore the pesticide residues in the main fruits produced in Henan province and provide guidance for the safe consumption of fruits, random samples were taken from different fruit markets in Zhengzhou city, and the residues of organophosphorus pesticides （Ops） and carbamate pesticides （CPs） in 10 kinds of fruits were detected using enzyme inhibition method. The results showed that different amount of OPs and CPs residues were detected among different kinds of fruits and different batches of the same fruit. The inhibition rate of cholinesterase by OPs and CPs was in the range of 0 to 75.55% in total of 50 batches of fruits, and the enzyme inhibition rates in 48 batches of fruits were less than 70%, 96% of the samples were in accordance with the agricultural industry standards. Residual pesticides were mainly concentrated in the peel, and the residues of OPs and CPs could be effectively reduced by washing.

Key words: fruit, pesticide residue, enzyme inhibition, rapid detection, food safety
