DETERMINATION OF SYNTHETIC COLORANTS IN CONFECTIONERY AND INSTANT DRINK POWDERS CONSUMED IN TURKEY USING UV/VIS SPECTROPHOTOMETRY

摘要

One hundred and forty samples of Turkish confectionery and 96 instant drink powders marketed in Turkey, colored with a single colorant, were analyzed for colorants using both quantitative and qualitative UV/VIS spectra-photometer determinations. Six and five synthetic food colorants were determined in confectionery and instant drink powders, respectively. All the synthetic colorants determined in confectionery, except for Erythrosine, are permitted for use by the Turkish Food Codex and European Community (EC). The permitted colorant levels in 63 (43.7%) of 135 confectionery and in 35 (36.45%) of 96 instant drink powder samples were determined to be higher than the maximum tolerable limit in the Turkish Regulations. Continuous surveillance programs may be warranted to monitor regularly the level of colorant in confectionery and instant drink powder consumed, especially by children.
