The efficiency of various household processing for removing chlorpyrifos and cypermethrin in Chinese kale and Pakchoi

The vegetables, Chinese kale and Pakchoi, which are popular among the Thai people, found to have problems with residues of pesticide. pesticide in both Kale Pakchoi were chlorpyrifos cypermethrin. This research was study efficiency residue reduction samples by using various household wash processing. process included washing normal water, 0.10% NaCl, baking soda, water flowing, blanching. Pesticide extracted from determine amount chlorpyriphos cypermethrin analytical tools such as Gas Chromatography— Flame Photometric Detector (FPD) Chromatography—Electron Capture (ECD). results showed that processes for reducing following: reduced 52.70–65.41%, 58.33–62.14%, 59.46–80.52%, 46.04–62.85% when washed flowing through, respectively. Similarly, 51.13–66.29%, 33.75–45.65%, 38.14–63.64%, 44.88–61.63% 10% Also, blanching 37.96–50.44% 47.86–52.42%. Therefore, while vegetables soaking dissolving substances, soda is most effective used at least 15 min reduce pesticides. consumers should be provided cleaned had a proper removing toxic residues.
