| 摘 要： | 使用气相色谱-质谱联用仪(gas chromatography-mass spectrometry,GC-MS)建立了聚乳酸(polyactic acid, PLA)发泡餐盒中2种爽滑剂(硬脂酰胺和芥酸酰胺)的检测方法,并研究这2种爽滑剂向3种食品模拟物的迁移,PLA发泡餐盒在40℃和70℃下与异辛烷、无水乙醇和95%体积分数乙醇的双面接触;使用毒理学关注阈值法(threshold of toxicological concern, TTC)对餐盒中2种爽滑剂进行风险评估。结果表明,2种爽滑剂向95%体积分数的乙醇和无水乙醇的迁移量几乎相同,均高于在异辛烷中的迁移量;与芥酸酰胺相比,硬脂酰胺向食品模拟物中迁移的更快,有更高的迁移率,但由于芥酸酰胺在餐盒中的初始含量远大于硬脂酰胺,所以芥酸酰胺的迁移量要大于硬脂酰胺;从PLA发泡餐盒中迁移到食品模拟物中的硬脂酰胺和芥酸酰胺,其估计日摄入量(estimated daily intake,EDI)分别为0.34 mg/(人·d),0.73 mg/(人·d),均超过安全阈值0.09 mg/(人·d),说明该PLA发泡餐盒作为食品接触材料使用时要严格控制爽滑剂的用量,确保食品安全。
