食品接触材料用硅橡胶检测研究进展

硅橡胶以其优良的稳定性和安全性被广泛应用于食品接触材料领域,随着硅橡胶在食品工业上的广泛应用,其使用过程中的安全性也逐渐受到人们的重视。本文综述了食品接触材料用硅橡胶中可能迁移出的有毒物质,列举了国际上关于食品接触用硅橡胶材料的相关检测标准及法规,介绍了分析推断硅橡胶老化机制的仪器分析方法,总结了食品接触用硅橡胶制品迁移到食品或食品模拟液中的环硅氧烷和重金属离子等有毒物质的具体检测方法。目前,在日常食品接触用硅胶制品的使用过程中,迁移到食品中最多的有害物质是挥发性环硅氧烷,国内外主要应用气相色谱法、气质联用法或核磁共振法来定性定量分析检测迁移到食品中的环硅氧烷。本文旨在对日常使用过程中硅橡胶的安全性的判断及国内食品接触用硅橡胶材料标准的制定提供一定的参考。

Research progress on detection of food contact silicone rubber

Silicone rubber is more widely used in food contact materials and its safety is becoming more and more important. In this paper, the possible toxic substances and the aging mechanism of the silicone rubber were introduced, the testing standards, national laws and regulations of the food contact silicon rubber material at home and abroad were listed, and the methods and instrumental analysis of the aging mechanism and the test of toxic substances in food contact silicone rubber were summed up. The highest siloxane migration was found in the food after preparation in a silicone rubber mould. Gas chromatography and gas chromatography tandem mass spectrometry could provide efficient tools for the analysis of siloxane migration found in the food which was baked in silicon rubber baking molds. It could provide a reference for the silicone rubber safety judgment of daily use, and to formulate the standard of domestic food contact silicone rubber.
