Abstract： Objective： To establish an analytical method for the simultaneous determination of the contents of fouradditives in pastries byevaporation-asisted dispersive liquid-liquid microextraction based on the solidification of floating organic droplets （EVA-DLLME-SFO） coupled with high performance liquid chromatography （HPLC）. Method： Pastry samples were extracted using methanol aqueous solution （70：30，V/V） ， then extracted by EVA-DLLME-SFO method，determined by high performance liquid chromatography，and quantified by external standard method. Result： The linear relationship of the four additives was good within the range of 0.25μg⋅mL-1 to 50.00μg⋅mL-1 .The detection limit of the method was 1.8mg⋅kg-1 to 6.0mg⋅kg-1 ，the quantification limit was 6.0mg.kg-1 to 20.0mg⋅kg-1 ， the sample recovery rate was 88.54% to 98.85% ，and the relative standard deviation was （20 0.22% to 1.37% . Conclusion： This method is environmentally friendly and highly precise，and is suitable for the rapid detection of various additives in pastries.
