Abstract

In this study, the level of migration of 5 kinds of volatile organic compounds (VOCs) (toluene, styrene, ethylbenzene, isopropylbenzene and n-propylbenzene) into distilled water from polystyrene-made food containers was measured using Purge&Trap combined with GC/FID. The contents of the VOCs which have regulatory limits in Korea food code only for material specification were determined under three exposure conditions which were 30 min at $60^{\circ}C$, 30 min at $95^{\circ}C$ and actual situation of instant noodle intake. The calibration curve of 5 compounds showed good linearity ($^r2$ = 0.9976~0.9995) within the concentration range of 1~50 ng/mL. The limit of detection (LOD) and limit of quantification (LOQ) were validated at range of 0.041~0.092 and 0.135~0.304 ng/mL, respectively. The average migration contents of 5 compounds were below 5 ng/mL except for styrene. The average contents of styrene were highly detected at $95^{\circ}C$ for 30 min exposure (52.71 ng/mL). Under actual condition at instant noodle intake, the average contents of styrene was 17.23 ng/mL. The results demonstrated that the migration rate of VOCs was related to storage temperature and time.

21종류의 폴리스티렌 용기를 대상으로 용출조건에 따른 용기내 증류수로 용출되는 5종의 VOCs(톨루엔, 스티렌, 에틸벤젠, 이소프로필벤젠 및 n-프로필벤젠)를 Purge&Trap 장치를 연결하여GC-FID로 분석하였다. 각 표준물질은 1~50 ng/mL의 농도범위에서 직선성($r^2$ =0.9976~0.9995)을 나타냈으며, 검출한계는 0.041~0.092 ng/mL, 정량한계는 0.135~0.304 ng/mL 이었다. 용출조건은 첫째, $60^{\circ}C$에서 30분, 둘째, $95^{\circ}C$에서 30분, 셋째, 실생활에서 컵라면 섭취시를 고려하여 끓은 물을 부은 후 뚜껑을 덮고 3분간 유지한 다음 뚜껑을 열고 5분 동안 개방하여 용출시키는 것으로 설정하였다. 톨루엔, 에틸벤젠, 이소프로필벤젠 및 n-프로필벤젠은 평균용출량이 모든 조건에서 5 ng/mL 이하로 검출되었으며 스티렌의 경우는 $60^{\circ}C$에서 평균용출량이 4.02 ng/mL, $95^{\circ}C$에서는 52.71 ng/mL, 컵라면 섭취시의 조건에서는 17.23 ng/mL로 검출되었다.
