Abstract

This study was conducted to examine the removal efficiency of 4 pesticides in Chinese cabbage (Brassica campestris L.) by different types of washing solution after harvest. To determine the removal efficiency of different washing solutions, samples were stored at 4℃, washed by different washing solutions and analyzed for amount of pesticide residues in Chinese cabbage. Removal efficiency of pesticide by tap water, baking soda (0.2%), charcoal water (20 g･L-1, pH 7.2), vinegar (5%) ranged from 26.5-83.8%, 32.7-93.3%, 40.3-89.7%, and 22.9-85.1%, respectively. The order of average removal efficiency of the pesticides was bifenthrin (82.7%), kresoxim-methyl (79.7%), pyraclofos (44.4%) and metalaxyl (38.2%). The washing efficiency of a pesticide is not correlated with its water solubility.
