< Topic >It designated that, sobriety in order to use for the acidic food and drink was decreased and was superior in flavor, offers the acidic soluble soybean albumin material as topic. SolutionsThe 7S globulin in all the protein/(the 11S globulin +7S the globulin) ratio is 0.4 or more at the time of the acidic solubilization processing where astringency increases, the acidic soluble soybean albumin material which by the fact that it uses the soybean albumin material which increases 7S globulin content as the raw materials, the astringency which it possesses originally it decreased largely with acidic solubilization processing, is superior in flavor was obtained.< Selective figure >It is not1/12【課題】酸性飲食物に用いるための、渋味が低減され風味に優れた、酸性可溶大豆たん白素材を提供することを課題とした。【解決手段】渋みが増加する酸性可溶化処理に際して、全蛋白質中の7Sグロブリン/(11Sグロブリン+7Sグロブリン)の比が0.4以上である、7Sグロブリン含量を増加させた大豆たん白素材を原料として用いることで、元々有する渋みが酸性可溶化処理により大きく低減した、風味に優れた酸性可溶大豆たん白素材を得た。【選択図】なし1/12
