Migration of di-(ethylhexyl)phthalate from PVC food packaging materials detected plasticizer into flood simulanting solvent

가소제가 검출된 PCV 식품용기에서의 식품유사침출 용매에 따른 디에틸헥실프탈레이트 용출에 관한 연구

Migration of di-(ethylhexyl)phthalate (DEHF) from PVC food packaging materials detected plasticizer into food simulanting solvents(4% Acetic acid, 8% Ethanol, 50% Ethanol, 95% Ethanol, Heptane) were studied. For executing this study ,2 PVC food packaging materials detected DEHP were used. Analysis was by GC-FID and GC-MSD(selected ion monitoring) for DEHP, and optimized for quantification of plasticizer. The recovery of DEHP into food simulanting solvents were min. 87.4${\pm}$ 3.6 ∼ max. 109.9 ${\pm}$ 10.7% respectively. Following exposure to food simulants 95% Ethanol for 24hours at 60$^{\circ}C$ the migration results of 1020.90 ${\pm}$ 10.15$\mu\textrm{g}$/g, 563.54 ${\pm}$ 5.60$\mu\textrm{g}$/dm$^2$and 73.51 ${\pm}$ 5.09$\mu\textrm{g}$/g 149.22 ${\pm}$ 10.34$\mu\textrm{g}$/dm$^2$were detected from the container for lunch and for stock fish respectively.

가소제가 검출된 PCV용기를 다른 식품유사침출용매(4%초산, 8%알코올, 50%알코올, 95%알코올, Heptane로 용출 실험한 결과, GC-FID와 GC-MSD(SIM Mode)에서 dimethyl phthalate(DMP), diethyl phthalate(DEP), 야-n-butyl phthalate(DBP), butyl benzyl phthalate(BBF), di(2-etylhexyl)phthalate (DEHP)의 분석한 결과 우수한 분리능력과 직선상을 보여주었다. 식품유사침출용매에 따른 전과정에 대한 각 프탈레이트 의 회수율을 시험한 결과. DEHP의 회수율은 4%초산에서 84.4 3.6%, 95%알코올에서 109.9$\pm$ 10.7%의 양호한 결과를 얻었으며, DEPH가 검출된 두 종류의 식품용기에서 식품유사침출용매에 따른 용출정도를 보기위해, 온도(2$0^{\circ}C$,6$0^{\circ}C$)와 시간(6시간,12시간,24시간,5일,10일)의 변화에 주어 실험한 결과, 도시락용기(1.10$\pm$0.18g,80$\mu\textrm{m}$ thickness)및 건어물용기(4.06$\pm$0.23g,240$\mu\textrm{m}$ thickness)모두 6$0^{\circ}C$ 95%알코올, 24시간에서 각각 1020.90 $\pm$ 10.15$\mu\textrm{g}$/g, 563.54 $\pm$ 5.60$\mu\textrm{g}$/dm$^2$, 73.51 $\pm$ 5.09$\mu\textrm{g}$/g 149.22$\pm$10.34$\mu\textrm{g}$/dm$^2$로 높았고, 시간경과에 따라 계속적인 증가 추세를 보였다.
