Abstract

Monosaccharides present in kappa -casein macropeptide (CMP) from bovine, ovine and caprine milks have been determined by gas chromatography after acid hydrolysis with trifluoroacetic acid (TFA) or methanolysis with HCl-methanol. The method has been evaluated for repeatability and recovery using myo-inositol as internal standard with satisfactory results. Galactose, N-acetyl-galactosamine and neuraminic acid were found in the kappa -casein macropeptides from the three species and similar levels of galactose and N-acetyl-galactosamine were found after treatment with TFA and HCl-methanol. BovineCMP exhibited the highest level of glycosylation. In general, the main component of the carbohydrate fraction was neuraminic acid. The method is suitable for the analysis of monosaccharides in CMP.
