Zusammenfassung:	2108286 9218542 PCTABS00016 In a method of oxidising carbohydrates, particularly starch and dextrin, the oxidation is effected by molecular oxygen in an alkaline aqueous medium in the presence of a catalytic quantity of a metal ion selected from the metals of group VIII of the periodic table, copper or silver and a substance which acts as a ligand for the metal ion and is preferably constituted by a polydentate amine ligand.
