Aglucone isoflavone enriched vegetable protein extract and isolate and process f or producing and recovering are disclosed. The aglucone isoflavone extract is made by extracting a vegetable protein material comprising glucone isoflavones with an a queous extractant having a pH above about the isoelectric point of the protein material to produce an aqueous extract, and reacting the glucone isoflavones with a sufficient amoun t of beta-glucosidase enzyme or esterase enzyme for a time period, temperature, and p H sufficient to convert at least a majority of the glucone isoflavones in the extract to aglu cone isoflavones and thereby produce the aglucone isoflavone enriched extract. The ag lucone isoflavone enriched isolates are produced by adjusting the pH of the reacted ext ract to about the isoelectric point of the vegetable protein material to precipitate the protein material, and separating the protein material to produce an aglucone enriched pr otein isolate.
