I. Properties and Structure
α-Cyclodextrin is a substance with a cyclic structure composed of six glucose units in a toroidal cone shape, featuring a hydrophobic core and a hydrophilic exterior. It is a tasteless, odorless, indigestible, non-caloric, and non-cariogenic sugar. It reduces the digestion of carbohydrates and lipids, has a low glycemic index, and also lowers the glycemic index of foods. In the EU, α-cyclodextrin has health claims that it can reduce the postprandial rise in blood glucose after starchy meals and can act as an emulsifier. It is generally used as a dietary fiber food.
The following are the application areas of the products:
II. Functions and Roles
Function in Food: In food products, the main function of α-cyclodextrin is to stabilize emulsions as an alternative to common emulsifiers. It acts as a surfactant in food, enabling water and fat dispersions to mix evenly and form stable emulsions. It is stable between pH 7.0 and 9.0 at 25°C and shows optimal activity at pH 8.5. It has an optimal temperature at 55°C and is stable for at least 1 hour at 50°C.
Health Effects:
Glycemic Control: May help improve blood sugar control by slowing down the absorption of carbohydrates. Like other fibers, α-cyclodextrin helps reduce glucose levels, especially postprandially. It contributes to a better glycemic response while significantly reducing serum insulin levels.
Anti-inflammatory: α-Cyclodextrin has been found to have anti-inflammatory properties, which may be beneficial in the treatment of conditions such as rheumatoid arthritis and osteoarthritis.

III. Applications in Various Fields
In almost all formulations, the basic purpose of cyclodextrins is to manage solubility, increase bioavailability, and enhance dissolution. Literature shows that cyclodextrins are also used in the development of novel carriers such as liposomes, microspheres, and nanoparticles.
The reasons for the use of α-cyclodextrins in the food industry include its nutritional and technological properties. It can act as a carrier for natural flavors, pigments, and vitamins, and as a stabilizer for oil-in-water emulsions. Consumption of α-cyclodextrins has been associated with several positive physiological effects, such as weight loss in rats, lower serum triglyceride and leptin levels, improved insulin sensitivity, and an increase in the amount of fat in feces.
