食品接触材料中挥发性气味物质分析技术的研究进展

Research progress on analysis technology of volatile odorant substances in food contact materials

目前食品接触材料安全性日益受到关注。食品接触材料产生的挥发性物质,常常具有异常的气味,可能通过气相传质或直接接触迁移至食品中,不但会引发食品感官特性的变化,影响消费者的使用体验,削弱消费者购买欲望,过量摄入后还会危及人体健康。因此,准确识别和检测食品接触材料产生的异味物质,对确保食品接触材料的合规以及保护消费者健康安全显得尤为重要。本文对国内外关于挥发性物质气味评估和检测技术及其在食品接触材料领域的运用进行综述。重点介绍了顶空、顶空-固相微萃取、热脱附、电子鼻等气味分析技术,及其与气相色谱、气相色谱/质谱或气相色谱-嗅闻-质谱仪等结合的联用分析技术,并梳理和展望了食品接触材料中挥发性气味物质分析技术发展前景,为有效管控食品接触材料异味问题提供技术参考。

At present,the safety of food contact materials is increasingly concerned.The volatile substances migrate from food contact materials by direct contact or through the gas-phase transfer occurred between the material and food surface probably have specific odor,which may cause the change of organoleptic character of food,affect consumers’experience and weaken the purchase desire.Furthermore,it may cause health problem if the migration level exceed the threshold limit of exposure.Therefore,it is important to identify and quantify the volatile substances from food contact materials,so that to ensure the compliance of food contact materials and protect the health and safety of consumers.This paper aimed to summarize the development of the techniques and approach for analysis of volatile substances and their applications in food contact materials,mainly introduced static headspace,headspace-solid-phase micro-extraction,thermal desorption and electronic nose,etc.,and the relevant identification technics by combination with gas chromatography,gas chromatograph/mass spectrometry or gas chromatographyolfactometry-mass spectrometry,etc,and reviewed and prospected the development of volatile odor analysis technology in food contact materials,so as to provide technical reference for effectively controlling the peculiar smell of food contact materials.
