Abstract: The protein preparation produced from rape seeds has a protein content of less than 90% based on the dry mass, has a brightness L*, determined according to CIE-L*a*b* color scale, of at least 70 and also has at least water-binding, oil-binding and emulsifying functionality. The method for producing a protein preparation includes dehulling the rape seeds and a mechanical deoiling process, wherein only part of the oil is separated and/or wherein the process is carried out at a temperature, averaged over the duration of the pressing process, of less than 80° C., and/or an extraction process wherein the amount of non-protein material is reduced in the protein flour and then the grain size is prepared in order to obtain a pourable material having a predetermined particle size distribution.

Abstract: The present invention relates to a method of obtaining protein preparations from sunflower seeds as well as protein preparations produced with the method. In the method the sunflower seeds are dehulled to a residual hull content of ?5% by weight or dehulled sunflower seeds with a residual hull content of ?5% by weight are provided. Mechanical partial deoiling of the dehulled sunflower seeds is carried out through pressing up to a fat or oil content of the dehulled sunflower seeds in the range 10 to 35% by weight. After carrying out one or more extraction steps with at least one solvent, a defatted flour containing protein is obtained as a protein preparation. Both optically and functionally the protein preparation has very advantageous properties which allow it to be used directly in the food product or animal feed sector.
