| 中文摘要: |
| 采用优化的超声提取法提取市售食品和食品包装袋中的邻苯二甲酸酯类化合物(PAEs)，并采用紫外-可见分光光度法(λ-max=227 nm)测定其含量，结果显示：被测定的食品和食品包装样品中普遍检出了PAEs，其含量范围在0~1 308.88 mg/kg之间；塑料袋包装食品中PAEs含量高于非塑料包装的食品；油脂含量高的食品中PAEs含量也高。结果表明，食品中PAEs主要来源于包装材料，高油脂是导致食品中PAEs含量高的一个重要因素。 |
| 英文摘要: |
| Phthalate acid esters in food and food packaging materials were extracted by ultrasonic extraction and determined by ultraviolet-visible light spectrophotometer (λ-max=227 nm). The results showed that PAEs were detected in samples universally, and the content range was (0~1 308.88) mg/kg; the PAEs content of foods in plastic packaging materials was higher than that in no-plastic packaging materials; and the PAEs content was high too in fat-rich foods. It was concluded that the contamination of PAEs in foods mainly comes from food packaging materials, and high lipid is one of the most important factor of increasing PAEs in food. |
