Iditol

Iditol is a hexitol, a type of sugar alcohol, and is the polyol corresponding to the aldohexose idose. It is formed by the chemical reduction of idose, yielding a six-carbon polyol with six hydroxyl groups. Its molecular formula is C6H14O6. Like other alditols, iditol is highly soluble in water and relatively stable under ordinary conditions.

Production and occurrence: Iditol is not commonly found in significant quantities in natural foods and is typically produced synthetically or via partial reduction of hexoses such as idose. It may be obtained commercially for use as a specialty sugar substitute or excipient.

Uses: In food and pharmaceutical applications, iditol can function as a low-calorie sweetener and as a humectant or stabilizer. It is less widely used than other sugar alcohols such as sorbitol or mannitol, but it is available for specific formulary or industrial purposes. Its sweetness is similar to other hexitols, though exact sensory properties can vary.

Safety and regulatory: As with other sugar alcohols, excessive intake of iditol can have a laxative effect and may cause gastrointestinal discomfort in some individuals. It is generally considered safe when used in moderation, but there are no widespread consumer guidelines or extensive regulatory approvals specific to iditol separate from the broader class of sugar alcohols.
