| The pesticide residues were monitored in 100 samples of 60 immature citrus fruits (putgyul) collected directly from orchards during cultivation and 40 putgyul products. A multi-residue method was applied for the analysis of 320 pesticides, and dithiocarbamates (mancozeb and propineb) were analyzed by patented Rapid Quantitation. 30 kinds of pesticides were detected in 100 putgyuls, but there were no samples exceeding the MRLs. The 20 samples with 30 pesticides were pre-treated to remove the residues using three washing and two juicing methods, and the reducing rate of residue was evaluated. Only 11 pesticides were reduced from at least 16.7% to 100% after washing, and from 16.0% to 94.0% in whole fruit juices, while the other 19 pesticides were not significantly different in the rate of decrease. However, all 30 pesticide residues were largely decreased in juices after removing citrus peel. Consequently, it was concluded that the residual pesticides in putgyuls were properly controlled. The monitoring yearly for the pesticide residue in immature citrus fruits may provide a basic safety information for the management of pesticides to producers and processing companies as well as the present results. |
