Outline of Final Research Achievements |
The effect of adding xanthan gum on starch digestibility and textural properties were investigated in rice and wheat flour blend breads. The addition of xanthan gum at concentrations greater than 1% to the bread formula caused a significant decrease in the extent of starch digestion. The results indicated that the effect of xanthan gum on starch digestibility was because of the molecular function and bread structure alteration. For rice gels prepared from cooked rice and rice flour, the gel network had a high impact on starch digestibility in rice gels.

Academic Significance and Societal Importance of the Research Achievements |
澱粉系食品・素材には近年血糖値上昇抑制効果が期待されており、食後血糖値上昇と関連性の高い澱粉酵素分解性の制御技術を開発できれば、食品の高機能化を可能にする加工技術に繋がる。本研究は、多糖類を添加したパンを試料として、「素材→加工→摂食」の過程における澱粉消化性の制御要因を網羅的に解析し、制御メカニズムを明らかにしたことで、食後の血糖値上昇を緩やかにする効果が期待できる食品加工技術の開発に寄与する新しい視点からの研究成果が得られたと考える。
