A method for obtaining proteins from native mixtures of materials, which comprises the following steps: - Step A: Providing a native mixture of materials from seeds having hard fragmentable hulls, in particular from whole legume seeds, whole sunflower seeds (seeds or fruits of Helianthus annuus) or soybeans, and/or whole seeds/fruits of Brassicaceae, in particular of rape fruit as mixture of materials from whole seeds or from already (partly) deoiled seeds, in particular as press cake, which remains as a residue of oil extraction in the pressing of oil, in particular using a press, termed "preliminary stage" and/or also "starting product"; - Step B: If the mixture of materials from step A is not yet comminuted: comminuting the mixture of materials, wherein, in each case, the hulls are disintegrated; - Step C: Dispersing the comminuted mixture of materials from step A) or B) with water, wherein, per one part of comminuted mixture of materials, preferably up to a maximum of 8, particularly preferably up to a maximum of 4 to 5, or 6 parts of water are added, and wherein the water and the comminuted mixture of materials are stirred, in such a manner that a free-flowing pulp and/or a dispersion is yielded; - Step D): Adjusting the pH of the pulp from step C) to an alkaline range pH > 9.5; - Step E): Adding the water-soluble organic solvent alcohol to the pulp from step D) subsequently to adjusting the pH of the pulp in step D; in such a manner that an alcohol concentration is achieved which is less than 30%, in order to detach the hulls from the endosperm of the seeds/fruits; - Step F): Separating off a solids phase which has the predominant fraction of the hulls, preferably in a centrifuge in the centrifugal field; - Step G): Shifting the pH of the pulp from step F) that is freed from the hulls to the pH range of pH = 4.5 to pH = 7.2; and - Step H): Separating the hull-free pulp, the pH of which has been shifted in step G) to the acid range, - preferably in a centrifuge, in particular in at least one decanter or a separator, into a plurality of phases, wherein one of these phases is a protein concentrate phase (protein curd), characterized in that the protein concentrate phase (protein curd) is dried to form a powder using a dryer-pulverizer. - Step A: Providing a native mixture of materials from seeds having hard fragmentable hulls, in particular from whole legume seeds, whole sunflower seeds (seeds or fruits of Helianthus annuus) or soybeans, and/or whole seeds/fruits of Brassicaceae, in particular of rape fruit as mixture of materials from whole seeds or from already (partly) deoiled seeds, in particular as press cake, which remains as a residue of oil extraction in the pressing of oil, in particular using a press, termed "preliminary stage" and/or also "starting product"; - Step B: If the mixture of materials from step A is not yet comminuted: comminuting the mixture of materials, wherein, in each case, the hulls are disintegrated; - Step C: Dispersing the comminuted mixture of materials from step A) or B) with water, wherein, per one part of comminuted mixture of materials, preferably up to a maximum of 8, particularly preferably up to a maximum of 4 to 5, or 6 parts of water are added, and wherein the water and the comminuted mixture of materials are stirred, in such a manner that a free-flowing pulp and/or a dispersion is yielded; - Step D): Adjusting the pH of the pulp from step C) to an alkaline range pH > 9.5; - Step E): Adding the water-soluble organic solvent alcohol to the pulp from step D) subsequently to adjusting the pH of the pulp in step D; in such a manner that an alcohol concentration is achieved which is less than 30%, in order to detach the hulls from the endosperm of the seeds/fruits; - Step F): Separating off a solids phase which has the predominant fraction of the hulls, preferably in a centrifuge in the centrifugal field; - Step G): Shifting the pH of the pulp from step F) that is freed from the hulls to the pH range of pH = 4.5 to pH = 7.2; and - Step H): Separating the hull-free pulp, the pH of which has been shifted in step G) to the acid range, - preferably in a centrifuge, in particular in at least one decanter or a separator, into a plurality of phases, wherein one of these phases is a protein concentrate phase (protein curd), characterized in that the protein concentrate phase (protein curd) is dried to form a powder using a dryer-pulverizer.
