目的 研究纸质包装材料中挥发性有机物向食品模拟物中的迁移量。方法 选取改性聚苯醚作为食品模拟物， 首次建立模拟物MPPO直接顶空进样-气相色谱/质谱联用法测定包装用纸中23种有机挥发物质迁移量的方法。结果 该法测定 23 种挥发性物质的相关系数 R 均大于 0.998， 相对标准偏差为1.4%～4.6%（n=7）， 检出限为0.03～0.60 mg/m2， 加标回收率为81.2%～110.2%。结论 该法无需前处理， 简单快速， 灵敏度高， 重现性好， 能满足包装用纸中23种有机挥发性物质迁移量的测定要求。

This experiment aimed to study the migration of organic volatile compounds from different paper-based packaging materials into food simulants. The method was established using direct headspace sampling-gas chromatography/ mass spectrometry (HS-GC/MS) for detecting the migration of 23 kinds of VOCs from paper packaging materials with modified polyphenylene oxide (MPPO) as food simulant. The linear correlation coefficients (R) were greater than 0.998, and the relative standard deviations (RSDs) were from 1.4% to 4.6% (n=7), with detection limits 0.03~0.60 mg/dm2 and recoveries 81.2%~110.2%. The method was simple, quick, sensitive and reproducible. The method was applied to analyze the 23 VOCs in two types of paper packaging materials, and can meet the requirements for the determination of the migration of 23 organic volatile compounds from paper packaging materials.
