A method for the determination of 80 pesticides (including five metabolites) in passion fruit using ethyl acetate extraction and dispersive solid-phase extraction followed by LC-MS/MS and GC-MS/MS was validated at LOQ of 0.005 or 0.010 mg kg (70 to 120% recovery; RSD ≤ 20%). Fifty-five passion fruit samples were obtained from producers, and 30 samples of frozen pulp and 12 samples of flour purchased. About 27% of the pesticides were detected; at least one in 60% of the peel samples, mainly imidacloprid and carbendazim (max. of 0.274 mg kg). Median processing factor was 0.5 for washed peel and 6.5 for dried peel (flour). About 63% of frozen pulp samples were positive, and 4 flour samples contained residues, mainly methamidophos. About 70% of the detected pesticides are not authorized in passion fruit in Brazil. Chronic and acute exposure from the consumption of passion fruit products did not indicate a health concern.
采用乙酸乙酯提取和分散固相萃取，结合 LC-MS/MS 和 GC-MS/MS 方法，对百香果中的 80 种农药（包括 5 种代谢物）进行了检测，检测限为 0.005 或 0.010 mg kg（回收率为 70%至 120%；RSD≤20%）。从生产商处获得了 55 个百香果样本，以及 30 个冷冻果肉样本和 12 个果粉样本。约 27%的样本检测出农药残留，果皮样本中至少有 60%检出农药，主要为吡虫啉和多菌灵（最高含量为 0.274 mg kg）。经清洗的果皮和经干燥的果皮（果粉）的加工系数中位数分别为 0.5 和 6.5。约 63%的冷冻果肉样本呈阳性，4 个果粉样本含有残留农药，主要为甲胺磷。在巴西，约 70%的检出农药未获批准用于百香果。食用百香果产品导致的慢性和急性暴露不会对健康造成影响。
