| 中文摘要: |
| 在不同条件下，将含有已知量抗氧化剂的聚乙烯和聚丙烯薄膜，在水、乙酸（3 g/L）、体积分数为10%,50%和95%的乙醇等5种食品模拟物中浸泡，在规定的时间点抽取一定量的浸泡液，采用超高效液相色谱法检测抗氧化剂含量，研究了迁移量及迁移率与时间、温度、模拟物属性、抗氧化剂初始浓度和聚丙烯材料的厚度等参数的关系。结果表明：食品模拟物的属性对抗氧化剂的迁移行为影响最大；迁移量和迁移率随温度的升高而增加；材料厚度增加，则抗氧化剂迁移量增加，而迁移率降低；薄膜中抗氧化剂初始浓度越高，则迁移量越大，迁移率越低。 |
| 英文摘要: |
| Under different conditions, PE and PP films containing known amounts of antioxidants were soaked in 5 simulants of water, acetic acid (3 g/L), ethanol (volume fraction 10%,50%,95%), and olive oil, for certain time; the soaking solution was analyzed by Ultra Performance Liquid Chromatography. The relationship of migration amount and migration rate with migration time, food simulant temperature, food simulant properties, initial concentration of antioxidants, and the thickness of packaging material was studied. The results showed that the nature of food simulant has prominence influence on migration behavior; number of migrated antioxidant species, migration quantity and migration rate increases with temperature rising; migration quantity is higher and migration rate is lower for thicker film; the higher initial antioxidant concentration the more migration quantity and the lower migration rate. |
