Simultaneous spectrophotometric determination of food colorants employing multivariate calibration methods

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...
