Alpha-cyclodextrin is a six-glucose cyclodextrin that is used as a soluble dietary fiber source. It is also used as a carrier for flavors, vitamins, fatty acids, and other ingredients. It can also be used to isolate bitter compounds and as a stabilizer, emulsifying fats in spreads or helping retain water or fat in fillings.
Alpha cyclodextrins are well tolerated in humans and have shown no adverse effects at normal intake. It is indigestible and used as a source of soluble fiber that can also trap molecules of fat within its structure, lowering overall energy absorption. See: Soluble fiber
