4.5 Sunflower
Sunflower press cake is a high-protein source, obtained after pressing of sunflower oil
by cold extraction. It is used in the production of combined fodders with a great
feeding value, which makes it possible to introduce a smaller amount of press cake
into combined fodder. The quality of proteins is rather higher than the quality of grain
crops and with a fat content of seven to 10% (up to 15%) it has high feeding and
energetic value. Sunflower press cake has a raw protein content of up to 38% and a
raw fiber content of up to 18% [ANONYM, 2010]. Furthermore, it has a high content of
vitamin E, 8.3 mg/100 g α-tocopherol and 0.5 mg/100 g β-tocopherol, high content of
phospholipids, vitamins of group B and β-carotene [FRANKE, 2010].
