Chemical Information
FooDB Name1-O-alpha-D-Glucopyranosyl-D-mannitol
DescriptionLow nutritive sweetener with half sweetness of sucrose. Component of *Isomalt* Isomalt is a disaccharide composed of the two sugars glucose and mannitol. It is an odourless, white, crystalline substance containing about 5% water of crystallisation. Isomalt has a minimal cooling effect (positive heat of solution), lower than many other sugar alcohols, particularly xylitol and erythritol. Isomalt is unusual as it is a natural sugar alcohol that is produced from beets. An interesting use of isomalt is found in the product DiabetiSweet, a sugar substitute sold for baking use and composed of a blend of isomalt and acesulfame potassium, but it has a bitter taste (due to the acesulfame potassium) and lacks the caramelizing properties of sugar.; Isomalt is a sugar substitute, a type of sugar alcohol, which is primarily used for its sugar-like physical properties. It has only a small impact on blood sugar levels and does not promote tooth decay. It has 2 kcal/g, half the calories of sugars. However, like most sugar alcohols, it carries a very real risk of gastric distress, including flatulence and diarrhea, when consumed in large quantities. And due to its laxative properties Isomalt is advised to not be consumed in quantities larger than about 50g per day for adults and 25g for children. The reason that isomalt may prove upsetting to the stomach is because the body recognizes it as a dietary fiber instead of as a simple carbohydrate. Therefore, like most fibers, it can increase bowel movements and it passes through the bowel in virtually undigested form. Like other dietary fibers, regular consumption of isomalt might eventually lead one to become desensitized to it, decreasing the risk of stomach upset. Isomalt is typically blended with a high intensity sweetener such as sucralose, so that the mixture has approximately the sweetness of sugar.

Description belongs to the class of organic compounds known as fatty acyl glycosides of mono- and disaccharides. Fatty acyl glycosides of mono- and disaccharides are compounds composed of a mono- or disaccharide moiety linked to one hydroxyl group of a fatty alcohol or of a phosphorylated alcohol (phosphoprenols), a hydroxy fatty acid or to one carboxyl group of a fatty acid (ester linkage) or to an amino alcohol.
