Furthermore colors are used to make food more visually attractive to Consumers. (Bonan and al, 2013) The determination of food dyes byHhigh Performance Liquid Chromatography UV detector diode array (HPLC -DAD ) allows the simultaneous determination in a single pass , identification and quantification of eleven synthetic food colors authorized by Moroccan and international regulation (EU Directive 1994/36/CE )( Figure 1). The analytical protocol includes a easy preprocessing procedure for the extraction of colors in foods . It offer an excellent combination of sensitivity and selectivity , simplicity and analysis time equal to 45 min , with relatively short quantification limits respectively ( 0.03 ppm and 0.09 ppm ) obtained by Canadian validation method (CENTRE D‟EXPERTISE EN ANALYSE ENVIRONNEMENTALE DU QUÉBEC, 2009).
