摘要
DEHP是塑料中常用的增塑剂之一,直接与内装高脂食品接触时,能够从塑料中迁移到内装食品中,造成内装食品的污染。DEHP对人体系统有不良影响,具有致畸、致癌的作用。本实验对各种材质(PVC、PE、PP、PS等)的食品塑料袋中DEHP的测定进行了较为系统的研究,采用气相色谱法,FID检测器,对DEHP进行测定。本方法检出限为3.38×10-3mg/kg,加标回收率为90.7%～105.1%,能够满足各种材质食品塑料袋中低浓度至高浓度DEHP含量测定的需要。
DEHP（Diz-ethy hexy phthalate） is widely used as plasticizer in determination of plastic materials and could contaminate the innerly packed food by packaging material migration when contacting the food. However DEHP is harmful to human health. This essay generally studied the methods of DEHP to determine food bags of different material such as PVC, PE, PP, PS etc. by means of GC and FID detector. Results showed that the determining limit is 3.38×10^-3 mg/kg and the recovery rate of the method lies between 90.7% and 105.1%. This method can be used to determine low to high levels DEHP in food bags.
