PURPOSE:To obtain a syrup containing branched oligosaccharide, by preparing an aqueous solution of glucose having a solid component concentration and a glucose concentration higher than specific respective range and passing the solution through a reactor filled with an immobilized enzyme having sugar- condensing action, at a temperature above a specific level. CONSTITUTION:An aqueous solution of glucose having a solid component concentration of >=60%, preferably >=70% and containing >=70%, preferably >=80% glucose (based on solid component), e.g. dissolved glucose crystal, refined glucose syrup, etc., is passed through a reactor containing an immobilized enzyme consisting of glucoamylase originated from microorganism belonging to Aspergillus genus or Rhizopus genus to obtain a syrup containing >=40% branched oligosaccharide (based on solid component). The temperature of the syrup passing through the reactor is >=60 deg.C, preferably 65-75 deg.C.
