説明

In previous papers the authors reported that browning products yielded by heating of lecithin (PC) were polymerized compounds formed of PC by aldol condensation.<BR>In this paper, catalysts and catalytic effect of the browning reaction of PC were investigated.<BR>Phosphorus and/or nitrogen containing compounds yielded by heating of PC were fractionated by solvents extraction and silicic acid column chromatography and their catalytic effects on the brown discoloration were examined. The results indicate that choline and/or phosphoric acid in PC accelerated the browning reaction. From the results obtained by the heating of PC with different solvents, it was suggested that browning reaction was accelerated mainly under anion catalytic reaction while action also showed some catalytic effect. Similar properties were noticed from both heated PC and synthetic conjugated dienone with phosphorylcholine.<BR>These results suggest that main condensing agent in browning reaction of PC is phosphorylcholine group in PC.
