  • Why is prepress solvent extraction better than sunflower meal?
  • Because sunflower oil has a substantially higher economic value than sunflower meal, process economics improve significantly as the oil recovery yield increases. Therefore, prepress solvent extraction, with the highest oil recovery yield, is the process method utilized today for the majority of the sunflower seed that is crushed globally.
  • How to refine sunflower oil?
  • Physical refining of sunflower oil is discussed in details. Recent developments in the field of processes, equipment and control have made it possible to refine by physical way the high phosphatide containing seed oils as well.
  • What is sunflower seed processing?
  • Sunflower seed processing focuses on sunflower oil as the most valuable product. It is used as high-value oil in various food applications. The deoiled meal is considered a byproduct and is mostly used as animal feed. In 2011, annual world production of deoiled sunflower meal was at 16 million tons (FAO, 2013).
  • Does topdressing increase oil content in sunflower seeds?
  • To increase the content of crude fat and linoleic acid in the oil of sunflower seeds, topdressing should not be used, or its use should be reduced, although this could reduce the content of protein, oleic acid, and palmitic acid. T he sunflower is one of the most economically important edible oil-producing crops in the world.
  • How can we improve the fatty acid composition of sunflower seed oil?
  • Sunflower responds well to applied N ( Chakor and Sharma, 1994 ), and the fatty acid composition of sunflower seed oil in five cultivars can be improved by manipulating the N supply rate and the time of N application in both glasshouse and field experiments ( Steer and Seiler, 1990 ).
  • How does N fertilizer affect oleic acid synthesis in sunflower seeds?
  • When basic N fertilizer (68 kg ha ?1) was used, subsequent topdressing N applications at the end of budding promoted the synthesis of protein, palmitic acid, and oleic acid in the oil of sunflower seeds, but decreased the CFC and linoleic acid content.
