As an example, five different synthetic colorants (Tartrazine, Sunset Yellow, Ponceau 4R, Amaranth, and Brilliant Blue FCF) from drinks and candies were separated on a polyamide adsorbent at pH 4, eluted with an alkaline-ammonia solution. By another method, 13 synthetic food colorants were isolated from various foods using specific adsorption on wool. After elution with 10% ammonia solution and gentle warming, an absorption spectrum of the resulting colorant solution was recorded, compared to the reference spectra of pure colorants, and identified by linear regression analysis. ...

CZE using cyclodextrins (CD) as buffer additives has also been employed for the determination of synthetic dyes in various food products. The synthetic dyes New coccine, Erythrosine, Allura red AC, Tartrazine, Sunset yellow FCF, Brilliant blue FCF, Indigo carmine and Fast green FCF were included in the experiments. Measurements were carried out in a used-silica capillary (47 cm length, 40 cm to the detector, 50 pm i.d.). Capillary temperature was 25°C and separation voltage was 20 kV. Pressure injection was performed... 

Fig. 9.2 Patterns of vertical water flow in a porous medium, as a function of the initial water content. Shown here are two patterns of water infiltration, in two different dry and wet soils, following infiltration of 40 mm of water containing Brilliant Blue FCF as a dye applied to the ground surface (Flury et al., 1994).
