| Samenvatting: | Title screen A fluorimetric method for simultaneous determination and quantification for of the synthetic food azo dyes Sunset Yellow (E110) and Ponceau 4R (E124) in soft drinks is proposed, which is characterized by high sensitivity and selectivity. These dyes are widely used in soft drinks, as they have a bright and attractive orange color. For determination of the dyes in beverages the working conditions for the analysis were selected: excitation wavelength is 330 nm, logging interval is from 350 to 500 nm for Ponceau 4R; the excitation wavelength is 250nm, logging interval is from 280 to 450 nm for Sunset Yellow. The possibility of simultaneous determination of two dyes of a red shade in a mixture is proved, as well as the repeatability of measurements of food azo dyes determination in non-alcoholic beverages by fluorimetric and spectrophotometric methods of analysis. |
