Disclosed is an extract produced by extracting an equol-containing valuable component from an equol-containing fermentation product of a soybean embryonic axis. Also disclosed is a method for producing the extract. An equol-containing fermentation product of a soybean embryonic axis is extracted by using an aqueous ethanol solution as an extraction solvent to extract an equol-containing valuable component from the fermentation product with a high degree of efficiency. Alternatively, an equol-containing fermentation product of a soybean embryonic axis is successively subjected to the extraction with an aqueous ethanol solution and the extract with ethanol to extract equol and glycitein with a high degree of efficiency, thereby reducing the content of a saponin that causes an unpleasant taste.

La présente invention concerne un extrait produit en extrayant un composant de choix contenant de l'équol d'un produit de fermentation contenant de l'équol issu d'un axe embryonnaire de soja. La présente invention concerne également un procédé de production de l'extrait. Un produit de fermentation contenant de l'équol issu d'un axe embryonnaire de soja est extrait en utilisant une solution d'éthanol aqueux comme solvant d'extraction pour extraire un composant de choix contenant de l'équol du produit de fermentation avec un degré d'efficacité élevé. En variante, un produit de fermentation contenant de l'équol issu d'un axe embryonnaire de soja est soumis successivement à l'extraction avec une solution d'éthanol aqueux et l'extrait avec l'éthanol pour extraire l'équol et la glycitéine avec un haut degré d'efficacité, réduisant de ce fait la teneur en saponine qui donne un goût désagréable.
