Cyclodextrins have the structure that D-glucose is bonded cyclically by α-1,4 bonding. Cyclodextrins include organics and change their characteristics. Therefore, cyclodextrins are used as stabilizers, antioxidants, antivolatilizers, and food additives. Three kinds of cyclodextrins which consist of 6 glucose(α), 7 glucose(beta), and 8 glucose(γ) are analyzed. Two columns, Asahipak GS-220 HQ and SUGAR KS-802 are used and the chromatograms show that better peak shapes can be obtained using GS-220 HQ.
