| Outline of Final Research Achievements |
High amylose brown rice, which has a high amylose content of rice starch, is heat-moisture treatmented using only water vapor. The aim is to develop a rice that is hard to raise postprandial elevation of blood glucose levels. Heat-moisture treatment increased the amount of resitant starch and decreased the rate of starch digestion. Low-GI rice foods have a milder post-meal blood sugar rise, conserve insulin secretion, and reduce the risk of diabetes and It is expected to have a preventive effect on metabolic syndrome. The administration of heat-moisture treatmented high-amylose rice to rats resulted in an increase in insulin levels caused by a rapid rise in blood glucose Secretion was inhibited and fatty acid synthesis induced by insulin was found to be suppressed.

| Academic Significance and Societal Importance of the Research Achievements |
米のアミロース含量と湿熱処理がラットの糖質・脂質代謝に与える影響を調べた。アミロース含量が高い米の方が低い米より難消化性デンプン含量が高く，デンプンの消化速度が遅いことがわかった。また，湿熱処理によって難消化性デンプンの増加，デンプン消化速度が低下することがわかった。ラットに投与した結果，血糖値上昇が穏やかなことに起因すると考えられる，肝臓酵素活性の変化が認められ，余剰糖質からの脂肪酸合成が抑制されることが明らかになった。湿熱処理高アミロース米は，血糖値上昇が穏やかで，糖尿病や肥満防止効果が期待できると考えられる。
