실험 절차

For example, the isomerisation of a maltose rich syrup is achieved by the addition of boric acid in at least equimolar quantities. The pH is then set at a value above 10, preferably close to 11. Isomerisation is then carried out at a temperature of about 50° C., over a period of between 4 and 5 hours. At the end of this isomerisation reaction, the yield from the conversion of maltose to maltulose is above 80%.
