Alpha-Cyclodextrin (usually referred to as CD) is a general term for a class of cyclic compounds composed of D-pyranose glucose units connected end to end through alpha-1,4-glycosidic bonds, which are generated by starch or polysaccharides under the action of cyclodextrin glucosyltransferase. Common molecules have 6, 7 and 8 glucose units, which are called α-cyclodextrin, β-cyclodextrin and γ-cyclodextrin in Chemicalbook. Since α-cyclodextrin can form inclusion complexes with many guest molecules, thereby changing the physical and chemical properties of the guest molecules such as solubility and stability, it has a wide range of applications in food, medicine, agriculture, textiles, environmental protection, cosmetics, biotechnology and analytical chemistry.

1) Adjust gastrointestinal function and improve constipation α-cyclodextrin will be decomposed by certain normal parasitic bacteria in the intestine and converted into a series of short-chain fatty acids such as acetic acid, propionic acid, and butyric acid. These short-chain fatty acids can inhibit the growth of harmful bacteria in the intestine and help the growth of probiotics such as bifidobacteria. The increase in the number of probiotics in the human body can in turn improve the body's immunity and prevent enteritis, intestinal cancer, dysentery and constipation. α-cyclodextrin is widely used in functional foods as a dietary fiber or additional material for improving metabolic syndrome.
2) Prevent and improve diabetes α-cyclodextrin can prevent sugar from being absorbed in the intestine, promote the excretion of sugar after inclusion, reduce the blood sugar peak after a high-starch meal, and achieve the effect of inhibiting the rise of blood sugar after a meal. α-cyclodextrin has a good effect on preventing and improving diabetes, and can be used as an effective blood sugar-lowering health food raw material for patients with hyperglycemia and type 2 diabetes to prevent postprandial hyperglycemia. EU Regulation No. 536 of 2013, in its statement on food nutrition and health claims, confirms that alpha-cyclodextrin has been scientifically proven to have the effect of regulating blood sugar. "Eating starchy meals containing alpha-cyclodextrin can reduce the rise in blood sugar after a meal." If the food with a meal size contains at least 5 grams of alpha-cyclodextrin for every 50 grams of starch, the chemicalbook manufacturer is allowed to indicate on the packaging that the product has the effect of lowering blood sugar.
3) Improve the stability of additives. Alpha-cyclodextrin can be used in combination with additives such as vitamin E, natural pigments (β-carotene, chlorophyll, etc.), and edible flavors (such as rose oil, anethole, etc.) to improve the stability of additives and facilitate long-term storage or preservation in food.

Cyclodextrin has a hole in the center of the ring structure, with -CH- oxygen atoms bound to glucoside inside, which is hydrophilic. The -OH groups at the 2nd, 3rd and 6th positions of glucose are hydrophilic and can complex other molecules into inclusion compounds through weak van der Waals forces. There are many substances that can be included by cyclodextrin, including rare gases, halogens, dyes, spices, drugs, foods, pesticides and preservatives. After inclusion, its stability, volatility, solubility and reactivity are improved. This special effect of cyclodextrin makes it an inclusion material with wide application value.
1. Uses in the pharmaceutical industry Cyclodextrin can form inclusion compounds (encapsulation) with drugs, which can (1) stabilize unstable drugs; (2) powderize deliquescent, sticky or liquid drugs; (3) solubilize (solubilize) poorly soluble or insoluble drugs, etc.
2. Uses in the pesticide industry Cyclodextrin inclusion stabilization can make some pesticides resistant to storage and improve insecticide efficacy.
3. Uses in the food industry Cyclodextrin is used in the food industry to have the following effects: (1) Elimination and masking of specific odors; (2) Improvement and modification of food tissue structure; (3) Reduction and removal of bitter taste; (4) Antioxidant effect; (5) Preservation and optimization of flavor.
4. Uses in the daily chemical industry Cyclodextrin can also be used as an emulsifier and quality improver in the manufacture of cosmetics. It also has deodorizing (such as removing bad breath) and preservative effects, and can be used in the manufacture of toothpaste and tooth powder.
5. Other uses In environmental protection, it can be used as a treatment agent for oily wastewater. Cyclodextrin aqueous solution is used to clean oil tanks, and its waste liquid can be recycled and treated to obtain fuel oil.
6. Uses of cyclodextrin in the chemical field Cyclodextrin is a valuable chemical reagent. When it is present, the fluorescence intensity of the fluorescent pigment will increase significantly, so it can be used for the analysis of proteins and amino acids; it can also be used to separate long-chain organic compounds, racemates, etc. In addition, adsorbents made of cyclodextrin can be used as adsorption for chromatographic analysis.
