PURPOSE:To produce a syrup containing a large amount of branched oligosaccharide having caries-preventing effect, extremely economically, by the industrial process based on the reverse synthesis with an enzyme. CONSTITUTION:An aqueous solution of glucose having a solid concentration of >=50% is made to react with an enzyme capable of condensing a saccharide (e.g. glucoamylase) to produce a branched oligosaccharide in the aqueous solution. The sugar syrup produced by the above process is a mixture containing glucose, maltose, etc. as well as branched oligosaccharides such as isomaltose, panose, isomaltotriose, etc. If necessary, the saccharides other than the branched oligosaccharides are separated and removed e.g. by the organic solvent treatment, to obtain a syrup of branched oligosaccharide having high concentration.
