PURPOSE:To adsorb an odoriferous component on silica gel selectively and to remove the component, by adding a solvent to a sucrose acetic acid isobutyric acid ester and bringing the solution into contact with silica gel. CONSTITUTION:Sucrose acetic acid isobutyric acid ester is blended with 1-10 times as much a solvent (e.g. petroleum ether, diethyl ether, hexane, methanol, ethanol, etc.) as the ester and brought into contact with silica gel (preferably spherical silica gel having 180-500mum) to purify the sucrose acetic acid isobutyric acid ester. The ester has improved adhesiveness, film characteristics, heat stability, electrical characteristics and ultraviolet light stability and is useful for coating compound, ink, plastic industry, food additive, perfume, cosmetic, etc. show.
