The reaction of glucose or fructose with primary amines and the thermal degradation of Amadori products of glucose leads to the formation of 6-formyl-1-alkylpyridinium-3-olates (5), of which 6-formyl-1-propylpyridinium-3-olate was isolated from a reaction mixture. A reference substance can be prepared in a two-step procedure from 5-(hydroxymethyl)-2-furaldehyde. Comparatively high yields of these betaines in relation to other UV-absorbing products are obtained under typical food processing and physiological conditions. With primary amines, the betaines readily form a Schiff base that undergoes Strecker-type degradation when heated in aqueous solution. Copyright (C) 1998 Elsevier Science Ltd.
