Abstract
This study investigated the effect of electrolyzed reducing water (ERW) on the reduction of profenofos (PF) and carbendazim (CBZ) residue of cherry tomato (Solanum lycopersicum var. cerasiforme). Organic tomato were soaked with pesticides solution (PF and CBZ) at 5 mg L-1, then air dried at room temperature. Thereafter, the treated fruits were washed with ERW at different concentrations (50, 100, 250, and 500 mg L-1) for various times (10, 20, and 30 min). The result found that the removal percentages of standard profenofos and carbendazim were significantly induced with ERW 500 mg L-1 for 20 min. Wherewith, the profenofos released the substance to pyrocatechol and 4-Methylphenol (p-Cresol), and carbendazim was degraded to a N-Acetyl-2,6-diethylaniline. The removal percentage of profenofos and carbendazim residues in tomato was found to be possible to effectively reduce residues 71.54% and 80.49%, respectively. On the other hand, distilled water (DW) could achieve removal of only 21.67%. The quality of the tomato stored at 25ºC for 8 days showed that not significant changes in weight loss, firmness, total soluble solids (TSS), titratable acidity (TA), lycopene content, and visual appearance for both pesticides.
