This invention relates to a process for producing cyclodextrins without using any organic solvents i.e. by non-solvent process. According to this invention, a sugar solution containing cyclodextrins and reducing sugars as primary ingredients is brought into contact with (i) a hydrophobic, synthetic adsorption resin comprising a porous polymer, (ii) a strongly acidic cation exchange resin or (iii) a strongly acidic cation exchange resin followed by gel resin particles, to thereby isolate a-, β-, y-cyclodextrins or a mixture thereof from the sugar solution. |
