Abstract

A process for the preparation of a sweetener, in which sucrose is converted enzymatically into a saccharide mixture which is called "isomerized sucrose" and has a disaccharide content of more than 85% by weight, then non-isomerized remaining sucrose is removed from the latter by enzymatic and/or H.sup.+ ion-catalyzed cleavage, and this product is catalytically hydrogenated. Preferably either before or after the catalytic hydrogenation, the resulting mixture is subjected to a chromatographic separation. The sweeteners prepared by this process contain either a mixture of 10 to 50% by weight of 6-O-.alpha.-D-glucopyranosyl-D-sorbitol; 2 to 20% by weight of 1-O-.alpha.-D-glucopyranosyl-D-sorbitol; and 30 to 70% by weight of 1-O-.alpha.-D-glucopyranosyl-D-mannitol or of 5 to 10% by weight of 6-O-.alpha.-D-glucopyranosyl-D-sorbitol; 30 to 40% by weight of 1-O-.alpha.-D-glucopyranosyl-D-sorbitol; and 45 to 60% by weight of 1-O-.alpha.-D-glucopyranosyl-D-mannitol.
