目的 研究食品接触用塑料制品中1-己烯特定迁移的测定方法，为制订相关检测标准、有害物质的检测与控制提供参考依据。方法 采用不同食品模拟物浸泡，再经顶空-气相色谱分析，研究顶空平衡温度、顶空平衡时间、色谱柱对1-己烯分析测试的影响。结果 在所选择的优化试验条件下，经色谱柱分离，在11 min内即可完成目标化合物的分离分析。1-己烯在0.5，1.5，3.0 mg/kg添加水平的回收率为86.0%～105.3%，相对标准偏差为1.5%～4.4%（n=6），方法定量限为0.1 mg/kg。结论 该方法快速、准确、灵敏，适合食品接触用塑料制品在不同食品模拟物中1-己烯特定迁移量的测定。

The paper aims to study the determination method of specific migration of 1-hexene in plastic products for food contact, to provide reference for the establishment of relevant testing standards and the detection and control of harmful substances. The effects of headspace equilibrium temperature, headspace equilibrium time, and chromatographic column on 1-hexene analysis were studied by immersion in different food simulants and analysis by headspace-gas chromatography. Under the optimized conditions, the target compounds can be separated and analyzed within 11 minutes through chromatographic column. The recoveries of 1-hexene at the addition levels of 0.5 mg/kg, 1.5 mg/kg and 3.0 mg/kg were 86.0%-105.3%, the RSD was 1.5%-4.4%(n=6), and the quantitative limit of the method was 0.1 mg/kg. This method is fast, accurate and sensitive, and is suitable for the determination of 1-hexene specific migration of food contact plastic products in different food simulants.
