| 中文摘要: |
| 采用气相色谱/质谱联用技术，利用外标曲线法分别测定了复合包装膜主要残留溶剂甲苯和乙酸乙酯在不同食品模拟物（蒸馏水、4%乙酸、65%乙醇、正己烷）中的迁移水平，同时比较了常温静置、超声波处理对残留溶剂迁移水平的影响。结果表明，乙酸乙酯的迁移水平非常低，可以视为未检出；甲苯在4种食品模拟物中的迁移量大小顺序为：正己烷＞65%乙醇＞蒸馏水＞4%乙酸；采用超声振荡处理能够加速残留溶剂的溶出，提高检测速度。 |
| 英文摘要: |
| By using gas chromatography/mass spectrometry and external standard method, the migration of main solvent residuals toluene and acetic ether of composite packaging film in different food simulacrums was determined. The food simulacrums were distilled water, 4% acetic acid, 65%ethanol alcohol, and normal hexane. At the same time, the influence of normal temperature stewing and ultrasonic treatment on residual solvents migration was compared. The result showed that migration in acetic ether is the lowest, which can deem as not detected; the migration amount of toluene in four food simulacrums from is ordered as normal hexane>65%ethanol alcohol> distilled water >4%acetic acid; ultrasonic treatment can speed up the migration and accelerate detection process. |
