Isomaltulose is a glucose-fructose disaccharide, found naturally in honey and sugarcane extract. Isomaltulose is produced by the biotechnological process, and is used as a functional carbohydrate because of its various nutritional and physiological properties.

In Japan, isomaltulose has been industrially used since 1985 in a wide range of products, including yogurt, chewing gum and sugar confectionery. In Europe, it was classified as "innovative food" recently. The main uses of isomaltulose as the sole sweetener are the production of sports and energy drinks, beverages that replace food, nutritional and energy bars, and cereal breakfasts.
