Beschreibung
Zusammenfassung:	To provide an extract obtained by extracting useful components containing equol from an equol-containing fermented soybean hypocotyl, and a method for producing the same.SOLUTION: The present invention makes it possible to efficiently extract useful components containing equol from the fermented soybean hypocotyl by subjecting an equol-containing fermented soybean hypocotyl to extraction treatment using an ethanol aqueous solution as an extractant. The present invention reduces the content of saponin, which causes an unpleasant taste, by sequentially subjecting the equol-containing fermented soybean hypocotyl to extraction treatment using an ethanol aqueous solution and to extraction treatment using ethanol, while efficiently extracting equol and glycitein.SELECTED DRAWING: None 【課題】本発明は、エクオール含有大豆胚軸発酵物から、エクオールを含む有用成分が抽出された抽出物、及びこれを製造する方法を提供することを目的とする。【解決手段】本発明では、エクオール含有大豆胚軸発酵物に対して、抽出溶媒としてエタノール水溶液を用いて抽出処理することにより、該大豆胚軸発酵物からエクオールを含む有用成分を効率的に抽出する。更に、エクオール含有大豆胚軸発酵物に対して、エタノール水溶液を用いた抽出処理及びエタノールを用いた抽出処理を順次実施することにより、エクオール及びグリシテインを効率的に抽出しつつ、不快味の原因となるサポニンの含有量を低減させることができる。【選択図】なし
