Abstract
A first-derivative spectrophotometric method was developed for quantit ative determination of synthetic organic dyes, Ponceau 4R (E124), Suns et Yellow (E110) Tartrazine (E102), which are used in food products un der governmental regulations all over the world because of their toxic ity and carcinogenity. In this study, Ponceau 4R with Sunset Yellow, a nd Tartrazine with Sunset Yellow, were simultaneously determined in th eir binary mixtures by first-derivative spectrophotometry. The method was applied to different sugar confectionery products. Recoveries were 93.8-101.2%, 92.1-107.9% and 94.9-99.2% for Ponceau 4R, Sunset Yellow and Tartrazine, respectively. The results were also compared by an in dependent method, thin layer chromatography (TLC). A t-test indicates that the differences obtained via the present methods and TLC were ins ignificant at the 95% confidence level. In addition, the present metho d is very rapid, economical and accurate. (C) 1998 Elsevier Science Lt d. All rights reserved.
