Abstract
The temperature sensitive differential of the solubilities of isoflavones is used to separate them by heating an aqueous soy molasses feed stream. The temperature of the feed stream is increased to select isoflavone fractions. Then the heated feed stream is passed through an ultrafiltration membrane. The resulting permeate is cooled to crystallize the isoflavone fractions. Or, the permeate may be put through a resin adsorption process in a liquid-chromatography column to separate out the desired isoflavone fractions. Various processes are described for drying and recrystallizing the resulting isoflavone solids.
