THE ACID-BASE AND CHROMATICITY CHARACTE RISTICS OF FOOD DYE «SUNSET YELLOW FCF»
Journal Title: Вісник Одеського національного університету. Хімія - Year 2014, Vol 19, Issue 2
Abstract
The acid-base properties of yellow food dye E110 «Sunset Yellow FCF» was studied by chemical chromaticity, spectrophotometric and potentiometric methods in aqueous solutions and identified relevant ionization constants. A probable scheme of dye functional-analytical groups’ dissociation and equilibrium its forms distribution diagram depending on the mediums acidity were proposed. The main spectrophotometric and colorimetric characteristics of the reagent individual forms were calculated.
