Saccharide induced racemization of amino acids in the course of the Maillard reaction.
The formation of D-amino acids on heating aqueous solutions of protein L-amino acids at pH 2.5 and pH 7.0 together with glucose, fructose or saccharose was investigated by enantioselective gas chromatography. The saccharide induced partial racemization (epimerisation) of L-amino acids is attributed to the Maillard reaction.
