Abstract
This study was conducted to investigate residue levels of chlorantraniliprole and ethaboxam in inner part and outer leaves of a head-type Korean cabbage. Further, reduction of residues was measured after water washing, blanching and heat-cooking of the outer leaves. For chlorantraniliprole, residues in inner part and outer leaves were <0.01 mg/kg and 0.0757 mg/kg, respectively, in case of three-time spraying 30 days before harvest and <0.01 mg/kg and 1.19 mg/kg, respectively, in case of four-time spraying 10 days before harvest; for ethaboxam, <0.05 mg/kg and 0.216 mg/kg, respectively and <0.05 mg/kg and 1.18 mg/kg, respectively. Chlorantraniliprole and ethaboxam were not detected in inner part of the head-type Korean cabbage. Residue levels in outer leaves were very high as 10-100 fold as those in inner part of the cabbage. Therefore, there is no concern for safety of pesticide residues on kimchi prepared with the inner part of a head-type Korean cabbage. In addition, it needs to be noted that outer leaves should be carefully removed at harvest of the cabbage. Outer leaves water washed and blanched are called as Woogeogi, which is consumed after heat-cooking. In Woogeogi, residue concentrations of two compounds reduced to less than 10%, and further less than 5% by heat-cooking. This indicates that considerable amount of the test pesticide residues in outer leaves of a head-type Korean cabbage removed through water washing, blanching and heat-cooking.
