Maltitol is a sugar alcohol (a polyol) used as a sugar substitute. It has 75-90% of the sweetness of sucrose (table sugar) and nearly identical properties, except for browning. It is used to replace table sugar because it has fewer calories, does not promote tooth decay and has a somewhat lesser effect on blood glucose. Chemically, maltitol is also known as 4-O-a-glucopyranosyl-D-sorbitol. Commercially, it is known under trade names such as Maltisorb and Maltisweet.
