Rapid and sensitive UHPLC screening of food dyes in carbonated beverages using UV/Vis wavelength switching Be the first to rate this application


The analysis of food dyes in carbonated beverages is important as many of these dyes are either controlled substances or are being phased out in certain countries due to their reported adverse health effects. Being able to identify and quantify food dyes in beverages quickly and with high sensitivity is therefore important. Reversed-phase chromatography is an excellent technique for the analysis of dyes. Many dyes are readily soluble in reversed-phase eluents and have strong visible and UV absorbance properties. This method demonstrates the separation of ten contentious dyes.
