PROBLEM TO BE SOLVED: To separate and obtain galactosylglycerols useful as foods, chemical products or feeds, etc., by fractionating a raw material solution comprising a galactosylglycerols-containing solution by a chromatography using an ion- exchange resin and collecting the. objective fraction. SOLUTION: The objective galactosylglycerols useful as a sweetener, a sweetness improver and a humectant, etc., in each field of a food, a chemical product and a feed are obtained by using a galactosylglycerols-containing solution comprising a transferred galactose-containing solution, etc., usingβ-galactosidase as a raw material, fractionating the galactosylglycerols in the raw material solution with another component by a chromatography using an ion exchange resin such as a calcium-type strong acidic cation exchange resin, a hydrogensulfite-type strong basic anion exchange resin, a carbonate-type strong basic anion exchange resin or a styrene-type strong basic anion exchange resin and collecting the galactosylglycerols fraction.
