An aglucone isoflavone enriched vegetable protein whey, whey protein material, high genistein material, high daidzein material, and aglucone isoflavone material are provided, as well as a process for producing the same from a vegetable protein whey. Isoflavone conjugates in a vegetable protein whey are converted to isoflavone glucosides by treating the whey at a temperature and a pH for a period of time sufficient to effect the conversion. The isoflavone glucosides are converted to aglucone isoflavones by enzymatic reaction to produce an aglucone isoflavone enriched vegetable protein whey. Aglucone isoflavone whey protein material is recovered from the aglucone isoflavone enriched vegetable protein whey. A high genistein content material, a high daidzein content material, and an aglucone isoflavone material are produced from an alcohol extract of the aglucone isoflavone whey protein material.

Aglucone isoflavone enriched vegetable protein whey whey protein

Disclosed are methods for converting isoflavone conjugates in vegetable protein materials to isoflavone aglucones by forming an aqueous mixture of a vegetable protein material containing isoflavone conjugates, converting the isoflavone conjugates to isoflavone glucones, and converting the isoflavone glucones to isoflavone aglucones. The vegetable protein material may also contain isoflavone glucones which are converted to isoflavone aglucones. The isoflavone conjugates, isoflavone glucones, or isoflavone aglucones present in the vegetable protein material may be removed from the vegetable materials before, during, or after the conversion process.
