| Research Abstract |
Soluble starch was treated with hot-compressed-water at the temperature range of 160-210 C using a continuous-flow reactor. Apart of the sample was converted to reducing oligosaccharides by hydrolysis with the hot-compressed- water. At 160-190 C the hydrolysis reaction occurred with the hot-compressed-water depending on a retention time. Over 200 C the behavior of generation of reducing oligosaccharides was found to be observed a maximum with increase of the retention time. From the results both hydrolysis reaction and resolution of a saccharide body occurred in the reaction mixture. The activation volumes of hydrolysis reaction at the range of 160-170 C were about 350 mL/mol. On the other hand, those at the range of 180-210 C were the values of 30-85 mL/mol. It was thought that the mechanism of hydrolysis reaction was different depending on the reaction temperature.
