摘 要: | 建立高效液相色谱法同时测定方便榨菜中安赛蜜、苯甲酸、山梨酸、糖精钠及脱氢乙酸5种食品添加剂的检测方法。采用高效液相色谱法,Waters Symmetry Shield C18(150mm×4.6mm,5μm)色谱柱进行分离,流动相为0.02mol/L乙酸铵缓;中溶液:甲醇(95:5,V/V),流速1.0mL/min,检测波长220nm,一次直接进样,同时测定5种食品添加剂。各物质在0.50~100.0mg&g范围内呈良好的线性关系,相关系数为0.9990~0.9999,精密度良好,加标回收率92.5%~98.8%,RSD〈3%。该方法准确度较高,重现性好,操作简便,能在20min内将5种添加剂完全分离,适用于大批量方便榨菜中常用食品添加剂的日常检测。

Abstract: | Detection method for simultaneous determination of 5 kinds of food additives namely acesulfame,benzoic acid,sorbic acid,sodium saccharin, dchydroacctate in convenience pickled mustard tubers by HPLC was made.Using high performance liquid chromatography, Waters Symmetry Shield C18( 150 mm×4.6 mm, 5 μm) 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. |
