Abstract
Detection method for simultaneous determination of 5 kinds of food additives namely acesulfame ,benzoic acid,sorbic acid,sodium saccharin,dehydroacetate in convenience pickled mustard tubers by HPLC was made.Using high performance liquid chromatography ,Waters Symmetry Shield C18(150 mm×4.6 mm,5μm) were isolated from the column,the mobile phase was 0.02 mol/L ammonium acetate buffer solution∶methanol(95∶5, V/V),flow rate of 1.0 mL/min,the detection wave length was 220 nm,a direct injection,simultaneous determination of 5 food additives.The materials in the 0.50~100.0 mg/kg showed good linear relationships ,the correlation coefficient were 0.999 0~0.999 9 ,good precision ,recovery rate were 92.5%~98.8%,RSD<3%. The method had high accuracy ,and it had good reproducibility ,and simple operation ,can be completely separated within 20 min of 5 kinds of additives ,applicable for routine determination of common food additives in large quantities of convenience pickled mustard tubers.关键词
