7 The Identification of Some Water-Soluble Food Colours by Thin Layer Chromatography 6r’A. Trafalgar Place, Portsntoutlt) Thin later chromatographic s1’stems using three different solvent n’ri)i!u.es are described lor the separation and identification of 23 per- rlitted and 6 non-pernliited \ater-soluble lood colours. Tl.re Authors’ laboratory had previouslv emplol’ed the solvent systems numbers 1. for the separation and identiflcation of water-soluble food colours. This metl.rod rvas satislactory but proved to be time-consuming, especially rihen it rias necessary to recover dyes for identi{ication by spectfophotometry. result of these lactors and the acknowledged advantages of thin layer chromatographl.
