Abstract: DMF in bread or cake was extracted by column chromatography by using acetic ether as estracting agent.The extract was directly determinated by GC with FID detector.If the method of determination of DMF in the bread and cade in this paper wasapplied,the loss of DMF would be reduced and the results would be satisfactory.
