[A study of the content of synthetic food dyes in gelatin jellies].
Methods of identification and quantitative determination of synthetic dyes in gelatine jellies have been described. Extraction and isolation procedures of synthetic food dyes have been developed specifically for gelatine products. The various techniques have been used as follows: paper chromatography, absorption spectrophotometry and polarography. Tartrazine, Cochineal Red and Indigotin in amounts permitted by Polish legislation have been determined.
