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.
