Processing and reducing factors of difenoconazole during ginseng processing

초록

This study was performed to acquire processing and reducing factors of difenoconazole during ginseng processing, and to establish the maximum residue limits of ginseng and its commodities. Difenoconazole was used in two fields (Wonju and Icheon) containing 6 year old ginseng plants. The amount of residue at Wonju and Icheon were <LOQ (0.02 mg/kg) and <LOQ (0.02 mg/kg) for fresh ginseng, 0.04 and 0.10 mg/kg for dried ginseng, <LOQ (0.04 mg/kg) and 0.08 mg/kg for red ginseng, 0.07 and 0.36 mg/kg for ginseng alcohol extract, <LOQ (0.04 mg/kg) and <LOQ (0.04 mg/kg) for ginseng water extract, 0.08 and 0.18 mg/kg for red ginseng alcohol extract, and <LOQ (0.04 mg/kg) and <LOQ (0.04 mg/kg) for red ginseng water extract, respectively. These data were under MRLs notified by the KFDA. The processing factors were 3.55, 3.17, 10.78, 2.00, 6.45, and 2.00, respectively, and the reduction factors were 1.09, 1.02 3.74, 0.73, 2.42, and 0.74, respectively. © The Korean Society of Food Science and Technology.
