Cyclodextrins (GS-220, KS-802)

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