Abstract

The effects of the industrial processing are evaluated of the removal of 16 pesticide residues in canned apricots and peaches and in orange juice. A method of multi-residual extraction that uses QuEChERS and liquid chromatography in tandem with triple quadrupole mass spectrometry was used. The method shows good linearity for the 16 pesticides studied (R2 > 0.999); it is accurate and precise (recoveries of 87-115%, relative standard deviation <8.0%). The processing factors are <0.6, indicating that all the processes significantly reduce the residue levels (spinosad, thiacloprid, pyridaben, bupirimate, flusilazole, triflumizole, flonicamid, imidacloprid, lambda-cyhalothrin, cyproconazole, fludioxinil and cyprodinil, abamectin, chlorpyrifos-methyl, hexythiazox and metalaxyl) initially present in the raw fruits and very significantly during washing/cutting, squeezing and hot pack canning (>55% loss). The risk quotient (EDI/ADI ratio) for canned foods is below 100, indicating that the potential consumer risk for the pesticides studied is practically negligent for human health.

摘要

评估了工业加工对杏罐头、桃罐头和橙汁中16种农药残留去除的影响。采用了一种多残留提取方法，该方法使用QuEChERS以及液相色谱串联三重四极杆质谱。该方法对所研究的16种农药显示出良好的线性（R2>0.999）；准确且精密（回收率为87 - 115%，相对标准偏差<8.0%）。加工因子<0.6，表明所有加工过程均显著降低了最初存在于原料水果中的残留水平（多杀菌素、噻虫啉、哒螨灵、联苯嘧啶醇、氟硅唑、三氟菌唑、氟啶虫酰胺、吡虫啉、高效氯氟氰菊酯、环丙唑醇、咯菌腈和嘧菌环胺、阿维菌素、甲基毒死蜱、噻螨酮和甲霜灵），在清洗/切割、榨汁和热罐装过程中残留水平降低非常显著（损失>55%）。罐头食品的风险商（EDI/ADI比值）低于100，表明所研究农药对消费者的潜在健康风险实际上可忽略不计。
