Outline of Final Research Achievements

This study investigated the rheological properties and functional evaluation of novel soybean flour-based foods compounded with amaranth flour. The specific volume of soybean flour bread increased with increased proportion of amaranth flour. The stress (strain 70%) increased gradually with the proportion of substituted amaranth flour was increased, and no change was observed at 75% or more. The texture softness was maintained even after three days of storage in the breads containing 0 to 50% of amaranth flour. The amount of daidzein and genistein in soybean flour bread tended to increase with fermentation time.

Academic Significance and Societal Importance of the Research Achievements

本研究では大豆粉パンの膨化性や食感を改善するために、大豆粉にアマランサス粉を併用した複合化食品を創製し、そのレオロジー特性及び機能性成分の挙動を検討した。その結果、大豆粉パンの一部をアマランサス粉に置換することで膨化が向上し、アマランサス粉の置換割合を0～50％にすると保存3日目においても軟らかさが保持されることを見出した。これらの成果は大豆粉及びアマランサス粉を利用する食品開発の一助になりうると考えられるが、今後もさらなる研究が必要である。
