• Sunflower oil is the most widely used oil due to its high linoleic content which is considered nutritionally positive. 
• The kernel accounts for 70% of the seed and the oil content is about 40%-45% in the seeds.
• Sunflower seeds are first subjected to decortication to obtain high protein meal, the decorticated sunflower seeds are subjected to mechanical extraction. 
• There are usually two methods that used in the sunflower seed solvent extraction. In one method only pre-pressing is carried out leaving 18 to 20% as residual oil in the pre-pressed cake. In the second method full pressing is carried out in screw presses leaving 10 to 12% residual oil in the fully pressed cake. 
• For recovery of residual left over oil in the cake, the cake is subjected to solvent extraction process.
• Refined Sunflower Oil is mainly used as food oil (salad and cooking) and in the manufacture of margarine.The meal is highly appreciated due to its high protein content (45-50%) as animal feed, especially for large breeding of poultry.
