The effects of alkaline and acidic electrolyzed water (AlEW, AcEW) treatment on the removal of pesticides (phorate, chlorpyrifos, lambda-cyhalothrin, cyfluthrin, procymidone, and chlorothalonil) and texture quality of fresh-cut cabbage, broccoli, and color pepper were investigated. AlEW efficiently removed pesticides from color pepper, whereas AcEW was the optimal treatment for pesticide removal from cabbage and broccoli. AcEW resulted in greater losses of pyrethroid and organophosphates than fungicides, while AlEW was superior for removing fungicides. The best pesticide removal from cabbage (72.28%-91.04%) was achieved by continuous oscillation treatment, while intermittent oscillation for 20 min achieved optimal results for broccoli and color pepper (72.28%-90.11% and 72.24%-88.12%, respectively). No significant deterioration in texture was detected in samples treated with electrolyzed water for 5-25 min. The results suggest that electrolyzed water treatment is effective for removing organophosphate, pyrethroid, and fungicide residues from fresh-cut vegetables while not negatively affecting their texture quality.
研究了碱性和酸性电解水(AlEW、AcEW)处理对去除蔬菜(辛硫磷、毒死蜱、高效氯氟氰菊酯、氯氟氰菊酯、腐霉利和百菌清)和新鲜切白菜、西兰花和彩椒的质地品质的影响。AlEW 能有效去除彩椒上的农药,而 AcEW 则是去除白菜和西兰花上农药的最佳处理方法。AcEW 导致拟除虫菊酯和有机磷的损失大于杀菌剂,而 AlEW 则更适合去除杀菌剂。白菜的最佳农药去除率(72.28%-91.04%)是通过连续振荡处理实现的,而对于西兰花和彩椒,间歇振荡 20 分钟(72.28%-90.11%和 72.24%-88.12%)则取得了最佳效果。经电解水处理 5-25 分钟的样品的质地没有明显恶化。结果表明,电解水处理能有效去除新鲜切蔬菜中的有机磷、拟除虫菊酯和杀菌剂残留,而不会对其质地品质产生负面影响。
