Abstract
This study was performed to acquire scientific data for establishing the maximum residue limits (MRLs) of pesticides in Korean red ginseng and its extract. Pesticides (azoxystrobin, fenhexamid, cyprodinil) were applied to a cultivated field of ginseng, and the fresh ginseng was harvested and processed to make Korean red ginseng and its extract. The reduction rates of the residue pesticides were calculated by determining the pesticide contents in each stage of ginseng processing. The residue levels in fresh ginseng were 0.12 ppm for azoxystrobin, 0.19 ppm for fenhexamid, and 1.78 ppm for cyprodinil. The residue levels in Korean red ginseng were 0.24, 0.54, and 1.49 ppm, and in the extract 0.81, 1.93, and 3.66 ppm for azoxystrobin, fenhexamid, and cyprodinil, respectively. The steaming and processing of fresh ginseng increased azoxystrobin and fenhexamid residues, but cyprodinil was reduced. The reduction rates (dry basis) of azoxystrobin, fenhexamid, and cyprodinil were 0.66, 0.94, and 0.28 for Korean red ginseng, and 3.25, 4.94, and 1.01 for the extract, respectively.
