METHOD FOR SEPARATION OF PROTEINS FROM PHENOLIC COMPOUNDS

A method for separation of proteins, particularly plant proteins, from salts and phenolic compounds in a liquid comprising said proteins dissolved in said liquid is provided. The method includes a step of subjecting said liquid to a first cross-flow membrane filtration process wherein the first salt...

Beschreibung
Zusammenfassung:	A method for separation of proteins, particularly plant proteins, from salts and phenolic compounds in a liquid comprising said proteins dissolved in said liquid is provided. The method includes a step of subjecting said liquid to a first cross-flow membrane filtration process wherein the first salts and at least a portion of the phenolic compounds migrate across the membrane into a first permeate and the proteins are retained in a first retentate; followed by a step of adding water, or one or more second salts and water to the first retentate, while continuing the membrane filtration process, to create a diafiltrate containing at least a portion of said phenolic compounds and the added second salts.
