Abstract
This study was carried out to elucidate changes in concentration of pesticide residues in Chinese matrimony vine and jujube during drying. Test pesticides, triadimefon and triforine for chinese matrimony vine and methoxyfenozide and thiacloprid for jujube, which are commonly used for the crops in Korea, were treated to the crops by spraying and dipping. The pesticide residues in both fresh and dried Chinese matrimony vine and jujube were analyzed by using a GLC-ECD and an HPLC-DAD. Processing factors of the pesticides in Chinese matrimony vine and jujube by drying ranged from 1.41 to 2.28 and from 1.50 to 4.20, respectively. And reduction factors of the pesticides in the crops ranged from 0.29 to 0.47 and from 0.68 to 0.98, respectively. These results indicate that concentrations of the pesticides in the test crops increased after drying, while amounts of pesticides in them were diminished by drying.
