Cyclodextrins are produced from starch by enzymatic conversion. They are used in food, pharmaceutical, drug delivery, and chemical industries, as well as agriculture and environmental engineering. ypical cyclodextrins contain a number of glucose monomers ranging from six to eight units in a ring, creating a cone shape:
α (alpha)-cyclodextrin: 6-membered sugar ring molecule
β (beta)-cyclodextrin: 7-membered sugar ring molecule
γ (gamma)-cyclodextrin: 8-membered sugar ring molecule
Due to its surface-active properties, α-cyclodextrin can also be used as emulsifying fiber, for example, in mayonnaise as well as a whipping aid, in desserts and confectionery applications. It has E number 459.
Cyclodextrins are used in baked goods prepared from dry mixes, breakfast cereal, chewing gum, gelatins and puddings, dry mix for soups, flavored coffee and tea, compressed candies, processed cheese products, flavored savory snacks and crackers, dry mix for beverages as a flavor carrier or protectant at varying levels.
