Abstract: A method for obtaining a protein ingredient for animal feed from seeds of sunflowers or rape includes shelling the sunflower seeds or rapeseeds up to a shell content of <2.5 wt %, mechanically partially extracting the oil from the shelled sunflower seeds or rapeseeds by pressing, up to a fat or oil content in the region of >6 and <25 wt %, and carrying out at least one extraction step for further extraction of the oil with at least one organic solvent or supercritical CO2, up to an oil content of less than 3.5 wt %; and subsequently desolventing, wherein at least one protein-denaturing treatment of the sunflower seeds or rapeseeds is carried out between the shelling of the sunflower seeds or rapeseeds and the obtaining of the protein ingredient. Due to its good digestibility, the protein ingredient can be used as an at least partial replacement for animal proteins in animal feeds.

Abstract: The present invention relates to a plant protein product with colouring ingredients and to a production method. In the method, a protein formula is provided which comprises plant proteins from oil seeds or from legumes and oil seeds, and secondary plant compounds from the oil seeds. In this method, the secondary plant compounds from the oil seeds contain polyphenols which alter their colour on oxidation. The polyphenols fraction selected for the protein formula. is between 10 ppm and 0.2%. The protein formula is then extruded at a temperature of more than 100° C. in the presence of atmospheric oxygen. The addition of proteins and of the aforesaid secondary plant compounds from the oil seeds allows different hues to be established in the vegetable extrudate that lend the impression of meat in any of a variety of prepared forms, without any need to add further colorants to the extrudate.
