  • Applications

    6-Kestose (CAS 562-68-5) is a fructooligosaccharide in the inulin family that is primarily used as a functional prebiotic ingredient in foods and dietary supplements to support gut microbiota; it is also evaluated as a cosmetic ingredient where it can act as a humectant and texture modifier in creams and lotions; in food processing it may serve as a carbohydrate source, bulking agent, and partial dietary fiber; in pharmaceutical and biotech applications it can be used as an excipient or an intermediate for glycosylation and enzyme-mediated synthesis; and in animal nutrition it can serve as a prebiotic feed additive.
