Abstract

A method for obtaining proteins from native mixtures of materials is disclosed. In an embodiment, the method includes: A): providing a native mixture of materials from seeds having hard fragmentable hulls; B): comminuting the mixture of materials; C): dispersing the comminuted mixture of materials with water; D): adjusting a pH of the pulp of step C) to an alkaline range pH>9.5; E): adding a water-soluble organic solvent alcohol to the pulp; F): separating off a solids phase from the pulp, which has a predominant fraction of the hulls, to form a hull-free pulp; G): shifting the pH of the hull-free pulp from step F) to a pH range of pH=4.5 to pH=7.2; and H): separating the hull-free pulp of step G) into a plurality of phases, wherein one of the plurality of phases is a protein concentrate phase.
