摘要
目的 讨论微塑料从食品包装、餐具、厨具、加工机械等食品接触材料中的释放途径和检测技术,为食品接触材料中微塑料选择和组合多样化的分析方法提供建议,为食品接触材料中微塑料及相关有毒有害物质的监测研究提供依据。方法 首先概述食品接触材料中微塑料的释放途径及影响因素,其次系统阐述食品接触材料中微塑料的分离富集技术,以及显微镜法、光散射法、光谱法和热裂解气相色谱质谱法等多种检测技术,针对不同技术的适用范围和特点进行比较和分析,并提出具有代表性的食品接触用材料中微塑料从样品处理到颗粒分析的框架和技术路线图,以识别微塑料的化学成分、形貌、丰度、尺寸及分布等特性。结论 针对不同的样品和场景,有必要选择和组合多样化的技术,以达到最优的路径,同时标准化的分析方法和检测技术处理仍是食品接触材料中微塑料风险评估的一大挑战,还亟待提出更为规范的标准化操作流程和检测技术,以提高结果准确性。
The work aims to discuss the release pathway and detection technology of microplastics from food pack-aging,tableware,kitchenware,processing machinery and other food contact materials,so as to provide suggestions for the selection of microplastics in food contact materials and analysis methods of diversified combinations,and provide basis for monitoring and research of microplastics and related toxic and harmful substances in food contact materials.The re-lease pathways and affecting factors of microplastics in food contact materials were overviewed.The separation and enrichment technology of microplastics in food contact materials,as well as various detection technologies such as mi-croscopy,light scattering,spectroscopy and pyrolysis gas chromatography-mass spectrometry were systematically ex-pounded.The application scope and characteristics of different technologies were compared and analyzed,and the framework and technical pathway of representative microplastics in food contact materials from sample treatment to par-ticle analysis were put forward to identify the chemical composition,morphology,abundance,size and distribution of mi-croplastics.For different samples and scenarios,it is necessary to select and combine a variety of technologies to achieve the optimal path.At the same time,standardized analysis methods and detection technologies are still a big challenge for microplastics risk assessment in food contact materials.More standardized operating procedures and detection technolo-gies are needed to improve the accuracy of results.
