Abstract

The present invention relates to a method for separating at least one soluble protein fraction from an aggregated casein-containing material, the method comprises the steps of: (i) providing the aggregated casein-containing material; (ii) Contacting the aggregated casein-containing material with a chromatographic support allowing one or more soluble protein(s) present in the aggregated casein-containing material to be retained by the chromatographic support; (iii) Obtaining a permeate fraction from the chromatographic support comprising aggregated casein; (iv) Optionally washing the chromatographic support; (v) Subjecting the chromatographic support to at least one elution buffer obtaining at least one soluble protein fraction from the chromatographic support; and wherein the chromatographic support comprises one or more mixed-mode ligands capable of binding the soluble proteins from the aggregated casein-containing material.
