Abstract

Researches concerning the spectrophometrical detection for the maximum of visible absorbance of a reaction mixture of methylglyoxal and cysteine in relation with previous results concerning the type of compounds released by this kind of Maillard system were done. Yellow-brownished pigments were generated immediately in the case of cysteine. Other amino acids tested in the presence of methylglyoxal remained colourless. The absorbtion spectra reached a maximum at 360 nm. The nature of the coloured compound remained unidentified at the moment. In addition, the influence of the solvent used on the variation of optical density by time was studied.
