Removal effect of pesticide residues in pears by different washing methods
The study explored the removal effects of different cleaning methods on seven commonly used pesticides in pears to determine the effective removal methods of pesticide residues in fruits in daily life.In the experiment,tap water and aqueous solution containing 2%,5% and 10% of salt,vinegar and baking soda were used to soaked for 10 min,and then the samples were washed for 30 s again.Finally,the concentrations of sev-en pesticides in pears were determined.The results showed that the type of cleaning agent and concentration had different effects on the removal rate.Among them,5% vinegar aqueous solution had the best effect on re-moving pesticide residues,and the removal rates of flusilazole,myclobutanil,tebuconazole,difenoconazole,clothianidin,imidacloprid and abamectin in pears were 40.20%,55.96%,18.70%,17.92%,55.88%,53.55% and 67.96%,respectively.The results of this study provide a reference for removing pesticide residues in pears and reducing the risk of dietary intake.
