| Abstract: | The method of determination of tartrazine in the cornmeal steamed bread by HPLC was established. The analysis column was Symmetry Shield RPls （3.9 mmx 150 mm, 5 Ixm） , the mobile phase consisted of ammonium acetate and methanol （vol- ume ratio was 18：72 ）, the flow rate was 0.6 mL/min and the detection wavelength was 254 nm. Samples components were extracted by mobile phase directly,and then analyzed by HPLC. The RSD was 2.2% （n = 7）, and the average recovery was 96.0% -97.2%. This method meets detection requirement. |
