The aim of this study was the development of a reversedphase
high-performance liquid chromatography method for the
simultaneous determination of 13 synthetic colorants into the
minimum run time in various classes of foods. All synthetic
food colorants permitted in EU market was efficiently separated
using an optimized gradient elution in a single run within 29 min.
The developed method was validated in different food matrices,
such as fruit flavored and alcoholic drinks, jam, sweets and sugar
confectionary and was successfully applied to the analysis of real
samples of water-soluble foods with simple pretreatment that
included water extraction for solid samples and water dilution
for liquid samples
