目的 研究可生物降解餐具中15种初级芳香胺(Primary aromatic amines，PAAs)的迁移行为。方法 制备4种不同的食品模拟液用于迁移实验，基于超高效液相色谱−串联质谱(UPLC-MS/MS)技术进行定性定量分析，检测PAAs从可生物降解餐具到不同食品基质中的迁移量。结果 UPLC-MS/MS的总运行时间为12 min，15种PAAs可以在7 min内分离。不同PAAs的检出限和定量限分别为0.2~3.0 μg/kg和0.5~9.9 μg/kg范围内，符合标准要求(10 μg/kg)。除1,5−二氨基萘和2,4−二甲基苯胺外，从可生物降解餐具迁移到不同食物基质的大多数PAAs的迁移浓度均小于最大残留限值。结论 在使用过程中，可生物降解餐具内部的PAAs会迁移到食品基质中，对消费者的健康存在潜在危害。采用所建立的方法对可生物降解餐具中的PAAs迁移量进行检测，为降低食品安全风险提供技术支撑。

The work aims to study the migration behavior of 15 primary aromatic amines (PAAs) in biodegradable tableware. Four different food simulant solutions were prepared for migration experiments. Qualitative and quantitative analyses were performed based on ultrahigh-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) to detect the migration of PAAs from biodegradable tableware to different food matrices. The total run time of UPLC-MS/MS was 12 min, and 15 PAAs could be separated within 7 min. The LODs and LOQs of different PAAs were between 0.2-3.0 μg/kg and 0.5-9.9 μg/kg, respectively, which met the requirement of legislation (10 μg/kg). The migration concentrations of most of PAAs migrated from the biode-gradable tableware to different food matrices were smaller than the required concentration except for the 1,5-diaminonaphthalene and 2,4-dimethylaniline. The PAAs in biodegradable tableware can migrate to food matrices during the usage, which is potentially harmful to consumers. The established method provides scientific support for reducing food safety risks by detecting PAAs migration amount in biodegradable tableware.
