出口内涂罐包装的游离酚GC-MS法迁移分析

GC-MS Technique Migration Analysis of Free Phenol in Export Packaging of Coated Cans

针对内涂环氧酚醛罐的出口食品包装产品,分析了国内外对材料中酚类等有害物迁移研究的差异。采用气相色谱质谱(GC-MS)技术,研究了内涂环氧酚醛罐中游离酚的定性定量分析检测,并通过模拟产品不同使用环境和条件,研究了游离酚向食品中的定向迁移特性。结果表明,所提方法不仅能检测出样品中的游离酚,背景干扰较少,还可对相应的游离酚化合物进行定性定量同步检测,且操作简单,灵敏度较高。该方法可为进一步补充和完善环氧酚醛内涂罐卫生标准的分析方法提供参考。

Focused on epoxy phenolic coated cans of export food packaging products, the differences between domes- tic and international migration studies regarding the free phenol toxic in the material were analyzed. Using gas chromatog- raphy-mass spectrometry （GC-MS） technique, qualitative and quantitative analysis of free phenol detection in epoxy phenolic coated cans were studied. By simulating different experiment environment and conditions, the directional migra- tion characteristics of food about free phenol were researched as well. The method could not only detect the free phenol with little background interference in the sample, but also achieve synchronous detection of qualitative and quantitative analysis of free phenol compound. The method is of the characteristics of simple operation and high sensitivity, and it could provide reference to the analysis method as further supplement and improve the sanitary standard of epoxy phenolic coated cans.
