Extraction and analysis conditions of di-(2-ethylhexyl) adipate (DOA) and its migration contents into foods wrapped with plasticized polyvinyl chloride (PVC) film during storage and cooking with microwave were examined using gas chromatography. Experiments on the extraction solvent and method showed that the method of reflux using carbon tetrachloride for longer than one hour allowed the highest extraction of DOA. Analysis of four PVC wrap films from different factories in domestic market showed the DOA contents of 18.9% for home-use and 24.6% for retail-use on the average. The highest migration during storage was observed in pork belly, which were 21% and 26% after one and three days respectively. During microwave cooking; smaller than 5.5% of DOA were migrated into foods when the film was not contacted with foods, whereas about 49% migration was observed in pork belly contacted with film directly.
