  • Applications

    Isomaltotriose (CAS 3371-50-4) serves as a carbohydrate source in food processing, used as a bulking agent and low-sweetness sugar replacer to improve texture in bakery, dairy, and confectionery products; it is often evaluated as a dietary fiber and potential prebiotic ingredient in functional foods and nutraceuticals. In cosmetics and personal care, it can act as a humectant and texturizing additive, aiding moisture retention and formulation stability in creams and cleansers. In pharmaceutical formulations, it may be employed as a carbohydrate excipient or filler and as a carrier for active ingredients in solid or liquid dosage forms. In industrial manufacturing, it can serve as a fermentable carbohydrate feedstock for microbial processes and enzyme production. Its role as a stabilizer or provider of consistent carbohydrate content can support formulation control across these sectors.
