An oil press KK20 F Universal with a standard / soft seed screw (Figure 7) and acapacity of 20 kg / hour (Kern Kraft, Germany) was used to press the sunflowerseeds. Sunflower oil was collected in a bucket and the press cake in a separatebasket. Diameters of 1 and 1.5 mm and speeds of 11 and 22 RPM were studied inorder to determine the optimum oil extraction conditions. Major caution was takenso that under these conditions the press would process the sunflower seeds attemperatures below 70 °C, which does not lead to a loss of advantageous nativefunctional structures [39]. The cake that contained the least amount of oil waschosen for fraction preparation
