| 中文摘要: |
| 在不同的条件下，将含有已知量增塑剂的PVC薄膜，在水、乙酸（体积分数为3%）、乙醇（体积分数10%）和橄榄油等4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，采用气相色谱-质谱法测定增塑剂含量，研究迁移量及迁移率与时间、温度、模拟食品属性、增塑剂初始浓度及包装材料厚度等参数的关系。结果表明：食品模拟物的食品属性对增塑剂的迁移行为有显著影响；增塑剂溶出种类数、迁移量和迁移率随温度升高显著增加；薄膜厚度增加，则增塑剂迁移量大，迁移率降低；薄膜中增塑剂初始浓度高，则迁移量大，迁移率低。 |
| 英文摘要: |
| Under different conditions, PVC films containing known amounts of plasticizers were soaked in 4 simulants of water, acetic acid (volume fraction 3%), ethanol (volume fraction 10%), and olive oil, for certain time; the soaking solution was analyzed by gas chromatography-mass spectrometry. The purpose was to study the relationship of migration amount and migration rate with migration time, food simulant temperature, food simulant properties, initial concentration of plasticizers, and the thickness of packaging material. The results showed that the nature of food simulant has prominence influence on migration action; number of migrated plasticizer species, migration quantity and migration rate increased with temperature rising; migration quantity is higher and migration rate is lower for thicker film; the higher initial plasticizer concentration the more migration quantity and the lower migration rate. |
