中文摘要:为促进食品中微塑料的治理,该文从食品中微塑料的来源、提取和分析方法等方面展开了系统综述,并针对食品中微塑料的规范分析提出了相关建议。研究表明从食品原料到生产加工过程及食品包装材料,都可能成为食品中微塑料污染的潜在来源。消解法是食品中微塑料提取的主要方法。目前,对食品中微塑料进行鉴别以及定量的主流方法有目检法、傅里叶变换-红外光谱、拉曼光谱、扫描电子显微镜、热裂解/气相色谱-质谱联用法等。今后,建议开展食品中微塑料检测的标准方法研究,开发纳米级微塑料的光谱鉴别和定量技术。同时,面对食品中越来越严重的微塑料污染情况,应加强微塑料在食品生产过程中的溯源分析和控制技术研究,加快新型材料的开发速度。
中文关键词:微塑料  食品安全  傅里叶变换-红外光谱  拉曼光谱  扫描电子显微镜  热裂解/气相色谱-质谱
 
Research Progresses on Source of Microplastics in Food and Their Identification Technology
Abstract:In this paper,the sources,extraction and analysis methods of microplastics in food were systematically reviewed,and the related countermeasures were proposed for the research of microplastics to promote the treatment of microplastics in food.Research has shown that food raw materials,processing and packaging are all potential sources of microplastics,while digestion is the primary method to extract microplastics in food.At present,the main methods for the identification and quantification of microplastics in food include visual method,Fourier transform infrared spectroscopy,Raman spectroscopy,scanning electron microscopy,pyrolysis/gas chromatography-mass spectrometry,etc.In the future,it is suggested that study on standard test method for microplastics in food should be carried out,and the spectral identification and quantitative techniques for nanoscale microplastics should be developed. Meanwhile,confronting more and more serious microplastics pollution in food,the traceability analysis and control technology research of microplastics pollution in the process of food production should be strengthened,and the development of new materials should be speeded up.
