Reduction of phoxim pesticide residues from grapes by atmospheric pressure non-thermal air plasma activated water

[Display omitted] •This work provides a novel plasma activated water strategy for reduction of pesticide.•The acidic environment and oxidation capacity are beneficial to the phoxim reduction.•Plasma activated water treatment will not significantly affect the quality of grapes.•One possible degradation pathway of phoxim is proposed.•The strategy provides a potential possibility for large-scale industrial production. In this study, we propose a novel strategy, plasma activated water (PAW) to reduce pesticide residues on agricultural products. To validate its feasibility and effectiveness, we employee high-performance liquid chromatography (HPLC) to detect phoxim on grapes. HPLC results suggest that the reduction of phoxim on grapes achieve 73.60% after treated 10 min by PAW prepared 30 min, and the concentration of phoxim decreased significantly (p
