| Abstract: | Food samples were purified by petroleum ether,extracted with acetonitrile,and determined by hydrogen flame ionization accurately.The linear correlation coefficient was 0.9998,the detection limit was 4mg/kg,the average recovery was 93.4%—100.9% with the relative standard deviation（RSD）of 2.5%—5.0%.This method can be applied to detect dimethgl fumarate in food. |
