柑橘中腈吡螨酯残留的超声波清洗去除效果研究

Study on the Effect of Ultrasonic Cleaning for the Removal of Cyenopyrafen Residues in Citrus

本文使用改进的QuEChERS法结合超高效液相色谱-串联质谱检测柑橘中的腈吡螨酯残留,研究了超声波清洗对柑橘中腈吡螨酯残留的去除效果。正交试验结果表明,在最佳清洗条件下,柑橘全果、果肉和果皮中的腈吡螨酯残留去除率分别为43.7%、21.6%、51.6%。本研究可为降低柑橘中农药残留的方法提供参考。

In this paper,a modified QuEChERS method combined with ultra-high performance liquid chromatography-tandem mass spectrometry was used to detect the residues of cyenopyrafen in citrus.The orthogonal test results showed that under optimum cleaning conditions,the maximum removal rates of cyenopyrafen residues in whole fruits,pulp and peel were 43.7%,21.6%and 51.6%,respectively.This study provided a reference for reducing pesticide residues in citrus fruits.
