METHOD FOR PREPARING A PROTEIN PREPARATION HAVING A REDUCED CONTENT OF PHENOLIC COMPOUNDS

摘要

Described is a method for preparing from a protein source containing phenolic compounds a water-soluble protein preparation having a reduced content of phenolic compounds, comprising the steps of a) precipitating the protein by bringing the protein source into a mixture of an aqueous medium and at least a water-miscible organic solvent, such that substantially no denaturation of the protein occurs, while the pH of which mixture deviates at most 1 pH value from the isoelectirc point of the protein, b) purifying the precipitate obtained in a).
