Description and Uses

Isomalt is an equimolar mixture of oc-D-glucopyranosyl-1,6- D-sorbitol (GPS) and α-D-glucopyranosyl-l,l-D-mannitol (GPM). The production process of isomalt involves two essential steps. In the first step, the 1,2 -glycosidic linkage between the glucose and the fructose moiety of sucrose is rearranged by an immobilized enzyme system to a 1,6 -glycosidic linkage, which is more stable and characteristic for the cross linkage in the amylopectin fraction of native starch. In the second step, the rearranged sucrose molecule, i.e., isomaltulose, is hydrogenated to the corresponding sugar alcohols. Isomalt is commercially available as a dry, white crystalline powder which is about half as sweet as sucrose.
In vitro studies with intestinal disaccharidases from mammals demonstrated that isomalt is cleaved much more slowly than sucrose or maltose. A slight inhibitory effect on maltose hydrolysis and on the active transport on glucose has also been observed.
Ingested isomalt is partly hydrolyzed in the small intestine and slowly absorbed in the form of glucose, sorbitol, and mannitol. The intact portion of isomalt, as well as some unabsorbed sorbitol and mannitol, reaches the distal parts of the gut where these products are fermented to volatile fatty acids.
