a synthetic FOS mixture was achieved through the selective complexation of glucose and fructose with phenyl boronicacid (PBAc) followed by ethyl-acetate extraction. The process was applied to a complexmixture of FOS obtained in an enzymatic synthesis reaction containing 40% glucose, 15.8% fructose and 35% of FOS, elimination of the sugars was achieved through 3:1 molar reactions, resulting in a levan-type

Glucosidase-catalysed synthesis of glucosides with a spacerarm on the anomeric carbon is reported. By using the acceptor as solvent at an elevated temperature, much higher yields of product have been obtained than previously observed.
