An object of the present invention is to provide a fermented seasoning containing 5-nucleotides derived from fermentation at a high concentration without externally adding 5-nucleotides and a method of producing the same. In a case where the nucleic acids are externally added, display of additives is indispensable on an ingredients description, and thus it cannot be said that the fermented seasoning have no chemical seasoning additive or made by natural brewing; however, with the fermented seasoning relating to the present invention, it is unnecessary to display additives on the ingredients description, and thus it is possible to appeal an added value to nature oriented or natural oriented consumers.

The present invention relates to an extract obtained by extracting useful components containing equal from an equol-containing fermented soybean hypocotyl, and to a method for producing the same. The present invention makes it possible to efficiently obtain useful components containing equol from the fermented soybean hypocotyl by subjecting an equol-containing fermented soybean hypocotyl to extraction 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 equal-containing fermented soybean hypocotyl to extraction using an ethanol aqueous solution and ethanol, while efficiently extracting equol and glycitein.
