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
