摘要: 本实验对塑料包装中的叔丁基对羟基茴香醚(BHA)、2,6-二叔丁基对甲酚(BHT)、β-(4-羟基-3,5-二叔丁基苯基)丙酸正十八酯(irganox1076)三种酚类抗氧化剂进行了研究。快速溶剂萃取(ASE)方法提取市售塑料食品包装中的抗氧化剂后,利用超高效液相色谱(UPLC)对其含量进行测定。结果显示大部分市售食品塑料包装中含有BHT及Irganox1076,基本不含BHA。

Abstract: The antioxidants BHA, BHT and Irganox1076 were extracted from the commercial food packages polyolefin by accelerated solvent extraction(ASE) technique and determined by ultra performance liquid chromatography (UPLC). The results showed BHT and irganox1076 are found in the majority of the food package samples, but BHA is almostly not found.
