title: [Simultaneous isolation of proteins and fats from oil seeds. I. Principle of procedure].
abstract: The principle of the procedure for the simultaneous isolation of proteins and fats from oil seeds is illustrated by the isolation of these constituents from sunflower seeds. This procedure is based on the displacement of oil and the extraction of protein by an aqueous electrolyte solution after comminution of the pretreated seeds, removal of the insoluble cell components and separation of the extracts into a fat-containing and a protein-containing phase. The globulins are precipitated isoelectrically; the albumins, by using complexing agents or thermal coagulation. The liberation of the oil from the concentrated fat emulsion is achieved immediately in a mechanical way or after addition of destabilizers. The results are discussed with regard to the yields obtained and the composition of the final products.
