A soluble isoflavone composition comprises isoflavone and a solubilizing agent consisting of anhydrous or water-containing propylene glycol and/or octenyl succinate-treated starch. The soluble isoflavone composition is prepared by, for instance, a method which comprises the step of heating isoflavone and a solubilizing agent consisting of anhydrous or water-containing propylene glycol and/or octenyl succinate-treated starch in the presence of water to thus solubilize isoflavone in water. The soluble isoflavone composition of the present invention has high solubility in water, is easily dissolved in water and is stable over a long period of time. |
