초록

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℃, 30 min at 95℃ 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 95oC 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.
