| 中文摘要: |
| 目的 对PE和PP/PE食品包装膜进行油墨涂覆处理并制样后开展迁移实验，探究油墨中芳香胺——对氨基偶氮苯的迁移行为和模型。方法 对比分析了5种不同添加浓度对氨基偶氮苯通过2种膜向4%乙酸、10%乙醇、95%乙醇模拟液中的迁移量，且对采集的实验数据通过Fick第二定律进行拟合，建立迁移模型。结果 对氨基偶氮苯的迁移量在迁移时间增加过程中不断增大，最终趋于平衡。不同模拟液中迁移平衡条件下对应的迁移量排序为4%乙酸>10%乙醇>95%乙醇，在模拟液相同条件下，迁移量和迁移物浓度存在正相关关系;各浓度条件下PE膜中的迁移量均高于PP/PE膜中的迁移量。确定出各模拟液中对氨基偶氮苯的迁移模型，然后利用实验数据检验所得模型，结果发现模型的预测准确性高。结论 所研究对氨基偶氮苯迁移规律及模型可用于预测芳香胺的迁移量，有较高实际应用价值，可为食品包装膜的油墨质量监督提供参考。 |

| The work aims to apply ink coating treatment to two different food packaging materials, PE film and PP/PE film, and prepare migration samples to investigate the migration behavior and models of aromatic amine - p-aminoazobenzene in the ink. The migration amount of five different concentrations of p-aminoazobenzene in ink through PE and PP/PE to three food simulation liquids of 4% acetic acid, 10% ethanol, and 95% ethanol was compared and analyzed. The collected experimental data were fitted by Fick's second law, and the migration model was established. The migration amount of p-aminoazobenzene showed a trend of firstly increasing and then gradually reaching equilibrium with the increase of time. At migration equilibrium, the migration amount in various liquids exhibited the order of 4% acetic acid>10% ethanol>95% ethanol, and it was obviously positively associated with solution content in the same simulated solution. In the same simulated solution, the migration amount in the PE under various concentrations was greater than that in PP/PE film. The migration model of p-aminoazobenzene in each simulated solution was determined, and then the model was tested by experimental data. The results showed that the prediction accuracy of the model was high. The migration law and model of p-aminoazobenzene can be used to predict the migration amount of aromatic amines, which has high practical application value and can provide reference for ink quality supervision of food packaging films. |
