We developed and validated a method for the simultaneous quant. anal. of food dyes in two food matrixes, i.e., chewing gum and soft drinks. Furthermore, we evaluated the stability of food dyes in these matrixes with respect to the pH and acid content. The optimized and validated method is based on high-performance liquid chromatog.-photodiode array (HPLC-PDA) and liquid chromatog.-tandem spectroscopy; the proposed method could identify and quantify 12 dyes in the two matrixes. The recoveries of the food dyes identified by HPLC-PDA anal. ranged from 98.61% to 118.42%, with relative standard deviations of 0.06-4.90%. In addition, the expanded uncertainties of the measurements ranged from 0.57 to 3.12%. Finally, the food dyes were found to be stable in the matrixes over 30 days. Thus, we believe that the proposed anal. method is suitable for the identification and quantification of food dyes in chewing gum and soft drink samples.
