A study of the voltammetric behaviour of the food colours brilliant blue FCF (C.I. 42090), erythrosine (C.I. 45430) and quinoline yellow (C.I. 47005) in the pH range 2-10 have been carried out by cathodic#10; stripping voltammetry. At pH 4.5 (acetate
A method for the simultaneous determination of the colorants Sunset Yellow FCF and Quinoline Yellow using solid-phase spectrophotometry is proposed. The colorants were isolated in Sephadex DEAE A-25 gel at pH 5.0, the gel-colorants system was packed in a 1
By the maximization test, using 0.5% D&C Yellow no. 11 in pet., 15 of 20 human volunteers became contact sensitized. All reacted to a challenge concentration of 1000 ppm and one down to 1 ppm. The high allergenic potential of
