MWCNT-modified Electrode for Voltammetric Determination of Allura Red and Brilliant Blue FCF in Isotonic Sport Drinks
(Wiley-VCH Verlag, 2019)
A fast and simple electrochemical sensor is presented for the determination of allura red and brilliant blue in isotonic sport drinks, using a glassy carbon electrode modified with multi-walled carbon nanotubes. The ...
Experimental and theoretical insights into the electrooxidation pathway of azo-colorants on glassy carbon electrode
(Elsevier Ltd, 2018)
Sunset yellow, Allura red and Ponceau 4R are azo-colorants with similar chemical structures. These colorants were studied by electrochemical methods at a glassy carbon electrode in phosphate buffer solution (pH 7.0), ...
Effect of organic synthetic food colours on mitochondrial respiration
(1996-01-01)
Eleven organic synthetic dyes, currently or formerly used as food colours in Brazil, were tested to determine their effect on mitochondrial respiration in mitochondria isolated from rat liver and kidney. The compounds ...
