摘要:  建立一种HPLC测定酱油中糖精钠、安赛蜜、阿斯巴甜等甜味剂的检测方法。样品经中性氧化铝柱、固相萃取净化,用ODS-C18柱分离,0.02mol/L硫酸铵水溶液(800ml)+甲醇(150ml)+乙腈(50ml)+10%硫酸(1ml)为流动相,进行分离。紫外检测波长为214nm。各种甜味剂均能得到较好分离,RSD为0.95%~2.05%之间(n=6),回收率为97.2%~102.2%之间。该方法灵敏度高,重现性和选择性好,回收率高,易于操作,是检测酱油中甜味剂的有效定量方法。

Abstract:  A rapid method using a reverse-phase high performance liquid chromatography for the determination of sweetening agent saccharin sodium, acesulfame-K, aspartame in the soy sauce was presented. Samples were purified with column chromatograph of alumina cartridge and solid phase column. The samples were separated on a ODS column with 0.02mol/L ammonium sulfate(800ml)+ methanol(150ml)+acetonitrile(50ml)+10% sulfuric acid(1ml)as the mobile phase and detected at UV 214nm. The variation coefficient was 0.95%~2.05% and the recovery was 97.2%~102.2%. This method was suitable for the determination of sweetening agent in the soy sauce.

Key words: soy sauce, sweetening agent, high performance liquid chromatography, quantitative analysis
