実験手順

As is evident from FIGS. 7 and 8, 1H-NMR spectrum of Isomerized saccharide A was completely identical with that of epilactose standard. As is evident from FIGS. 9 and 10, 1H-NMR spectrum of Isomerized saccharide B was completely identical with that of lactulose standard. From the results, it was confirmed that Isomerized saccharides A and B, formed from lactose, are epilactose and lactulose, respectively.
