1. IntroductionCyclodextrin is series of cyclic oligosaccharides produced through glucotransferase by Bacillus, with multiple glucopyranose molecules composed of 1,4-glycosidic bonds in a cone-shaped cylindrical structure. The inner cavity of cyclodextrin is hydrophobic, while the outer cavity is hydrophilic. When the quantity of glucopyranose monomers is seven, it is called β-cyclodextrin (BCD), which has the inclusion…
