The removal amount of pesticide residue which were remained in baechu (Chinese cabbage) and perilla leaf were measured during the preparation process of kimchi. The amounts of diazinon, procymidone and endosulfan applied to chinese cabbage were 9.18 ± 0.03 mg/kg, 22.27 ± 0.22 mg/kg and 10.46 ± 0.02 mg/kg respectively. When chinese cabbage was brined with 10% salt solution for 12 hours, the removal rates of three pesticides were 22.5%, 25.3% and 0.6% for diazinon, procymidone and endosulfan, respectively. When chinese cabbage was brined and rinsed 3 times with water, the removal rates of three pesticides were 69.9%, 85.6% and 11.2% for diazinon, procymidone and endosulfan, respectively. When kimchi was prepared and fermented for 28 days at 4o C, the removal rates of three pesticides were 79.4%, 94.4% and 21.0% for diazinon, procymidone and endosulfan, respectively. The relative percentages of removal dose of pesticides during brining were 28.4%, 26.9% and 3.2% for diazinon, procymidone and endosulfan, respectively and which were 59.7%, 63.8% and 50.4% during rinsing and which were 11.9%, 9.3% and 46.4% during fermentation, respectively. The amounts of diazinon, procymidone and endosulfan applied to perilla leaf were 18.11 ± 0.62 mg/kg, 31.80 ± 0.33 mg/kg and 12.01 ± 0.01 mg/kg, respectively. When perilla leaf was rinsed 3 times with water, the removal rates of three pesticides were 60.5%, 52.0% and 23.7% for diazinon, procymidone and endosulfan, respectively. When perilla leaf was rinsed and brined with 10% salt solution for 14 days, the removal rates of three pesticides were 93.9%, 92.4% and 49.6% for diazinon, procymidone and endosulfan, respectively. The relative percentages of removal dose of pesticides during rinsing were 64.5%, 56.3% and 47.8% for diazinon, procymidone and endosulfan, respectively, and which during brining were 35.5%, 43.7% and 52.2% for diazinon, procymidone and endosulfan, respectively.
