摘要
建立同时测定6种人工合成甜味剂阿斯巴甜、糖精钠、甜蜜素、安塞蜜、纽甜、甜聚糖甙的高效液相色谱分析方法。以Platicil ODS柱为分离柱,20mmol/L硫酸铵缓冲溶液(pH4.4)-乙腈为流动相,进行梯度洗脱。采用二极管阵列检测器进行检测,整个分离过程在30min内完成。6种甜味剂在0.4～120mg/L范围内其质量浓度与峰面积的线性关系良好,相关系数为0.99967～0.99998,在4.0～10.0mg/kg范围内,样品加标回收率为85%～107%;相对标准偏差小于3.2%。该方法简便、快速,净化效果较好,可用于食品中6种甜味剂的同时测定。
A reversed-phase high performance liquid chromatography（RP-HPLC） method was established to simultaneously determine six artificial sweeteners including aspartame（ASP）,sodium saccharin（SA）,sodium cyclamate（SC）,acesulfame potassium（AK）,neotame（NTM） and stevioside.The separation was carried out on a Platicil ODS（250 mm×4.6 mm,5μm） column through gradient elution using 20 mmol/L（NH4）2SO4-acetonitrile（pH 4.4） as mobile phase.The whole separation process was completed in 30 min before diode array detection.An excellent linear relationship between peak area and sweetener concentration in the range of 0.4-120 mg/L with a correlation coefficient varying from 0.99967 to 0.99998 was observed.The recovery rates of spiked samples in the range of 4.0-10.0 mg/kg ranged from 85% to 107% with a relative standard deviation less than 3.2%.Therefore,this method is characteristics of simple operation,rapid detection and excellent purification efficiency so that it can be used for the routine analysis of these sweet additives in foods and beverages.
