PURPOSE:To prepare reduced starch sugar product having excellent inclusion capacity, low viscosity, and high age resistance and coloring resistance, by hydrogenating a saccharified sugar liquid composed of cyclodextrin and glucose, maltose and oligosaccharide under high pressure in the presence of a catalyst. CONSTITUTION:A decomposed startch liquid composed of cyclodextrin and dextrin can be prepared by reacting gelatinized starch liquid or liquefied starch liquid with cyclodextrin-producing enzyme. The decomposed starch liquid or a filtrate obtained by crystallizing and removing beta-cyclodextrin from the decomposed starch liqud is made to react with a saccharifying enzyme capable of decomposing dextrin to saccharides having low polymerization degree such as glucose, maltose, oligosaccharide, etc. without decomposing cyclodextrin. The starch liquid is converted to starch sugar liquid composed of cyclodextrin, glucose, maltose, oligosaccharide and a small amount of dextrin by the action of the saccharifying enzyme, and is hydrogenated under high pressure without decomposing cyclodextrin in the liquid. |
