Research progress on sample pretreatment and detection methods of food contact materials

Recently, food safety issues caused by the migration of hazardous substances from food contact materials have drawn great attentions from all walks of life. The hazardous substances in food contact materials are characterized by various kinds, wide sources, complex components and strong unpredictability. Therefore, the key to the safety evaluation of food contact materials is to select appropriate sample pretreatment methods and combine them with fast, sensitive, accurate and multi-component simultaneous detection. This paper briefly introduced the perniciousness of hazardous substances in food contact materials, categories of food contact materials and sources of non-intentional added substances, with emphasis on sample pretreatment methods of food contact materials and detection methods of hazardous substances in food contact materials. Finally, it analyzed the problems of analysis methods for hazardous substances in food contact materials and summarized the development tendency of composition analysis of food contact materials.
