摘要： Cowpea, a typical vegetable characterized by a consistent growth and harvest period, often accumulates high pesticide residues in pods. The household washing process has the potential to impact both pesticide residue and the quality of cowpea pods. This study investigated the behavior of tolfenpyrad and cyromazine in cowpea pods using in situ mass spectrometry imaging, analyze changes in nutrients, and explore typical metabolite alterations following the washing process. Both tolfenpyrad and cyromazine levels on the surface of the cowpea were significantly reduced after the washing process, although cyromazine distributed inside the cowpea remained at a high level. Immersing cowpeas in 2% NaHCO 3 for 30 min and a 3 min tap-water rinse resulted in the removal of 72% and 58% of tolfenpyrad, 66% and 50% of cyromazine, respectively. Importantly, a 3 min tap-water rinse did not impact nutrient content, while other 30 min immersions led to a reduction in typical nutritional factors. Furthermore, the levels of typical metabolites such as tamarix, quercetin, and aspartic acid were down-regulated, while malic acid, glucose, and ascorbic acid were up-regulated in cowpea after pesticide immersion. The concentrations of all six metabolites in cowpea decreased after the washing procedure.
