Simultaneous spectrophotometric determination of food colorants employing multivariate calibration methods
This study investigated the simultaneous spectrophotometric determination of three food colorants - Tartrazine (T), Ponceau 4R (P) and Indigo carmine (I) - in mixtures employing multivariate calibration methods. Absorption spectra of 76 mixtures of the colorants were recorded. The 76 spectra were di...
