Evaluation of Different Sweetener Concentrations in Beverage Samples in Isfahan Market Using High Performance Liquid Chromatography

Abstract

Sweeteners were added in beverage formulations to provide sweetness with pleasant taste. In this paper, potent approach for quantification of acesulfame ok (ACE-ok), sodium saccharin (Na-SAC) and aspartame (ASP) contents in beverages had been applied with liquid chromatography (RP - HPLC) joint with diode array detection (DAD). Ninety-seven samples have been selected from Isfahan marketplace. Liquid chromatograph Agilent 1260 Infinity series was applied for analysis. Mobile phase was decided on as acetonitrile and phosphate buffer (pH= 3.5) with 15:85 extent ratio (V/V), and the float rate of the chromatographic device was Optimized at 1 ml min-1 using an isocratic elution system. All the beverages were saccharin-free and the mean concentrations of acesulfame and aspartame were lower than the general standards of the Iran National Standards Organization (600 mg L-1). All the products were showed the acceptable levels of sweeteners, but, periodical and exact evaluation of these sweeteners in the beverages are still suggested to provide consumer health.
