Abstract:
A process for obtaining a purified isoflavone material from soy molasses comprising:providing a soy molasses material containing isoflavones;condensing said soy molasses material so that said condensed soy molasses material contains at least 10% solids, by weight;maintaining said condensed soy molasses material at a temperature of about 0.degree. C. to about 20.degree. C. and a pH of about 3 to about 6.5 to render said isoflavones insoluble in a liquid fraction of said condensed soy molasses material;separating an insoluble isoflavone enriched material from said liquid fraction of said condensed soy molasses material; andextracting said isoflavones from said insoluble isoflavone enriched material.
