Changes in Pesticide Residue Amounts on Frozen Cherries Over Time

25371

The aim ofthis study was to determine changes over time in pesticide residue amounts on cherries which were frozen unwashed and after being washed. Cherries collected from Senirkent region (Isparta) were divided into two groups as washed and unwashed. The samples were stored at -20 °C for six months. Pesticide residues analyses were carried out through the use of gas chromatography device. The first chromatographic analysis was performed on the day when cherries were collected. Analyses were repeated once a month during storage period (six month). In this way, changes in pesticide residue amounts were determined for the washed and unwashed cherries that were kept frozen. According to results obtained, while there happened a decrease in pesticide residue amounts for the washed cherries kept frozen, this decreased was periodical (first day 0,6 mg/kg, at the endof the sixth month 0,2 mg/kg). On the other hand, it was found that decrease in pesticide residue amounts for the unwashed cherries fell off as freezing storage period increased (first day 1,1mg/kg, at the end of the sixth month 0,1 mg/kg).
