Abstract

A total of 100 commercially available olive oil products were analyzed for 179 pesticide residues using gas chromatography-tandem mass spectrometry (GC/MS/MS). The olive oil samples were mixed with organic solvents, centrifuged and frozen to remove fat, and pesticide residues were analyzed using the "quick, easy, cheap, effective, rugged, and safe" (QuEChERS) method. The determination coefficient (R2) of the analysis method used in this study was ≥0.998. The detection limit of the method ranged 0.004-0.006 mg/kg and its quantitative limit ranged 0.012-0.017 mg/kg. The recovery rate (n=5) measured at the level ranging 0.01-0.02, 0.1, and 0.5 mg/kg ranged 66.8-119.5%. The relative standard deviation (RSD) was determined to be ≤5.7%, confirming that this method was suitable for the "Guidelines for Standard Procedures for Preparing Food Test Methods". The results showed that a total of 151 pesticides (including difenoconazole, deltamethrin, oxyfluorfen, kresoxim-methyl, phosmet, pyrimethanil, tebuconazole, and trifloxystrobin) were detected in 64 of the 100 olive oil products. The detection range of these pesticide residues was 0.01-0.30 mg/kg. The percentage acceptable daily intake (%ADI) of the pesticides calculated using ADI and estimated daily intake (EDI) was 0.0001-0.1346, indicating that the detected pesticides were present at safe levels. This study provides basic data for securing the safety of olive oil products by monitoring pesticide residues in commercially available oilve oil products. Collectively, the analysis method used in this study can be used as a method to analyze residual pesticides in edible oils.

시중 유통 중인 올리브유 100건의 잔류농약을 조사한 결과 64건에서 8종(difenoconazole, deltamethrin, oxyfluorfen, kresoxim-methyl, phosmet, pyrimethanil, tebuconazole, trifloxystrobin)의 잔류농약이 검출되었다. 검출된 농약을 중심으로 확인한 시험법의 결정계수(R2)는 0.998 이상 이었으며, 검출한계는 0.004 mg/kg-0.006 mg/kg, 정량한계는 0.012 mg/kg-0.017 mg/kg이었다. 0.01-0.02, 0.1 0.5 mg/kg 수준으로 측정한 회수율(n=5)은 66.8-119.5%, relative standard deviation (RSD)는 ±5.7% 이하로 나타나 식품등 시험법 마련 표준절차에 관한 가이드라인'에 적합한 수준임을 확인하였다. 검출된 농약 8종의 %ADI는 0.0001-0.1346으로 안전한 수준으로 나타났다. 본 연구는 유통 중인 올리브유의 잔류농약을 모니터링 함으로서 올리브유의 안전확보를 위한 기초자료를 제공하고자 하였으며 본 연구에서 이용한 분석법은 식품 자체가 기름으로 구성되어 있는 올리브유 등 식용유지에서 잔류농약을 효과적으로 분석할 수 있는 방법으로 활용될 수 있을 것으로 기대된다.
