Mineral hydrocarbons are used as processing aids at levels between 0.3 and 3% by weight in crystal polystyrene articles, the food contact uses of which include the dispensing of hot and cold beverages from automatic machines as well as in 'fast-food' and catering establishments. The levels of migration of mineral hydrocarbons from polystyrene cups and glasses have been measured into aqueous food simulants as well as lager, beer, cola, sparkling apple juice, lemon barley water, coffee, hot chocolate, tea, lemon tea and chicken soup. For the cold beverages and simulants, no migration above 0.1 mg/kg was observed, and for the hot beverages and simulants no result greater than 0.5 mg/kg. Analysis was by capillary gas chromatography, using hydrocarbon internal standards calibrated against mineral hydrocarbon reference standards.
矿物烃类在结晶聚苯乙烯制品中用作加工助剂，用量为0.3%至3%（按重量计），其食品接触用途包括通过自动售货机分发冷热饮品，以及在“快餐店”和餐饮场所使用。已测定矿物烃类从聚苯乙烯杯和玻璃杯向水性食品模拟物以及贮藏啤酒、啤酒、可乐、气泡苹果汁、柠檬大麦水、咖啡、热巧克力、茶、柠檬茶和鸡汤中的迁移水平。对于冷饮和模拟物，未观察到迁移量超过0.1毫克/千克，对于热饮和模拟物，未观察到结果大于0.5毫克/千克。分析采用毛细管气相色谱法，使用针对矿物烃参考标准校准的烃类内标物。
