Abstract
Methods for recovering isoflavones and derivatives thereof from soy molasses are disclosed. In a first embodiment, a method is disclosed in which isoflavones are recovered without any significant conversion of isoflavone conjugates to other forms. In a second embodiment, a method is disclosed whereby isoflavone conjugates are converted to glucosides while in the soy material prior to their recovery. In a third embodiment, a method is disclosed in which isoflavones are converted to their aglucone form while in the soy material and prior to their recovery. Also disclosed are various isoflavone enriched products obtained from soy molasses.
