Headspace sampling and gas chromatographic determination of styrene migration from food-contact polystyrene cups into beverages and food simulants.
Migration studies using coffee, tea, water, and 8% ethanol were conducted with various types of food-contact polystyrene cups. Study conditions simulated filing and storage at room temperature and hot-filling or pasteurization above 150 degrees F (65.6 degrees C). The quantity of styrene migrating was determined by headspace sampling and gas chromatography (GC). The GC column was 6% Carbowax 20M on Chromosorb 101 with quantitation via a flame ionization detector. Detection limits ranged from 3 to 10 ppb in various liquids. The method and results of the migration studies are presented.
