中文摘要:

      目的 对快餐和早点包装中邻苯二甲酸酯类(PAEs)塑化剂迁移至食品中的风险进行评估。方法 采集42批次一次性餐盒, 依据GB/T 21928-2008《食品塑料包装材料中邻苯二甲酸酯的测定》, 采用气相色谱-质谱法对样品中的PAEs含量进行检测; 并依据GB/T 23296.1-2009选择迁移实验浸泡条件, 考查样品中PAEs的迁移风险。结果 42批次快餐和早点包装中, 共计有26批次样品中检出PAEs增塑剂, 占总抽检批次的61.9%。其中24批次检出含量在0~10 mg/kg范围内, 最高检出含量为93.5 mg/kg。迁移实验中只有含量最高的样品检出DEHP迁移量为0.06 mg/kg。结论 快餐和早点包装中PAEs总体暴露水平低于100mg/kg, 正常使用过程中迁移风险较小。

英文摘要:

      Objective To evaluate the migration risk of the phthalic acid esters (PAEs) from the packaging of fast food and breakfast. Methods Totally 42 batches of disposable fast food box were collected and the contents of the PAEs were determined by gas chromatography-mass spectrometry, according to GB/T 21928-2008 (Determination of phthalate esters in food plastic packaging materials). The migration risk was also investigated with the corresponding soaking condition according to GB/T 23296.1-2009. Results There are 26 batches (61.9%) of the 42 batches were found to have PAEs. In this event, the contents of PAEs in 24 batches were in the range of 0~10 mg/kg with the highest content 93.5 mg/kg. In the migration experiment, only 0.06 mg/kg of diethylhexyl phthalate (DEHP) was detected in the samples which were of the highest content of PAEs. Conclusion The exposure level of PAEs in the packaging of fast food and breakfast is lower than 100 mg/kg, which is less risky of migration during normal use.
