Alpha-Cyclodextrin (synonyms, cyclohexaamylose, cyclomaltohexaose, alpha-Schar-dinger dextrin) is a non-reducing cyclic saccharide comprised of six glucose units linked by alpha-1,4 bonds. It is produced by the action of cyclodextrin glucosyltransferase (CGTase, EC 2.4.1.19) on hydrolysed starch syrups at neutral pH (6.0–7.0) and moderate temperature (35–40 oC). The annular (or doughnut-shaped) structure of alpha-cyclodextrin provides a hydrophobic cavity that allows formation of inclusion complexes with a variety of non-polar organic molecules of appropriate size. The hydrophilic nature of the outer surface of the cyclic structure makes alpha-cyclodextrin water-soluble.

Alpha cyclodextrin is a naturally occurring cyclic oligosaccharide, it is enzymatically produced from starch.Alpha Cyclodextrin has hydrophobic cavities. It forms inclusion compounds with organic substances, salts, and halogens in the solid state or in aqueous solutions. It is incompatible with strong oxidizing agents.

The hydrophobic cavity and the hydrophilic outer surface of alpha-cyclodextrin form the basis for its use in the food industry. alpha-Cyclodextrin, like its homologues beta- and gamma-cyclodextrin, can function as

1)A carrier and stabilizer for flavors, colors, and sweeteners;

2)An absorbent for suppression of undesirable flavors and odors in foods;

3)An absorbent for suppression of halitosis (in breath-freshening preparations);

4)A water- solubilizer for fatty acids and vitamins.
