Abstract: The invention relates to chewing gum containing 1.1-GPS (1-O-&agr;-D-glucopyranosyl-D-sorbitol), especially a sweetening agent mixture of 6-O-&agr;- D-glucopyranosyl-D-sorbitol (1.6-GPS), 1-O-&agr;-D-glucopyranosyl-D-sorbitol (1.1-GPS) and 1-O-&agr;-D-glucopranosyl-D-mannitol (1.1-GPM).

Abstract: A method is disclosed for producing di- and more highly oxidized carboxylic acids from a compound selected from a first group consisting of carbohydrates, carbohydrate derivatives and carbohydrate derivatives having more than one primary alcohol group, comprising oxidizing, in an aqueous solution in a concentration between 0.1% and 60%, the compound selected from said first group and a compound selected from a second group consisting of monooxidized carbohydrates, monooxidized carbohydrate derivatives and monooxidized carbohydrate derivatives having more than one primary alcohol group, with one of oxygen and an oxygen-containing gas, on one of a noble metal catalyst and a mixed metal catalyst; electrodialyzing the oxidized compounds in at least one electrodialysis stage; and removing said di- and more highly oxidized carboxylic acids in said at least one electrodialysis stage.
