摘要: Pesticide residues in peach crisps, a daily leisure snack, are insufficiently investigated. This study comprehensively explored the dissipation, metabolism, processing factors (PFs) and risk assessment of 15 commonly used pesticides in peaches from field cultivation to crisp processing. Field trial results suggest that the half-lives of the surveyed pesticides were 3.40–10.05 days in peaches. Furthermore, the metabolites clothianidin and trifloxystrobin acid were detected at concentrations of 4.28–39.79 μg/kg. All pesticide residues became concentrated in the peach crisps after freeze-drying (PF: 1.34–4.80). Contrarily, peeling and washing removed varying amounts of pesticide residues from peaches (PF: 0.076–1.24, most <1). Notably, the octanol–water partition coefficient exhibited a significant positive correlation with the crisp PFs. Dietary risk assessment results indicated that chronic and acute health risks were considered to be within acceptable limits for children and the general population. The results provide important references for promoting healthy consumption of peaches and peach crisps.
