Establishment of DEHP Determination in Plastic Food Bags by GC

Abstract

Abstract: 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.

Key words: DEHP, GC, food safety, determine
