  • 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 is sunflower seed processed for oil production?
  • Figure 1 shows a flowchart of sunflower seed processing for oil production that results in sunflower seed byproducts (whole and defatted sunflower meals) (Figure 2). The process starts with the crushing of the seed, where the whole sunflower meal is generated.
  • How is sunflower crushed for oil recovery?
  • Sunflower is crushed for oil recovery via one of two process methods, hard pressing or prepress solvent extraction. Hard pressing relies upon exerting high pressure on the prepared seed to separate oil from the solids fraction, historically recovering about 25% oil from the seed.
  • How is sunflower meal extracted?
  • Then, the whole sunflower meal is subjected to a new extraction process using solvent, usually hexane or methanol and defatted sunflower meal/cake is generated as a byproduct (Table 1). After this, the oil filtration or decantation step is realized, whose purpose is to separate waste.
