• What is the composition of sunflower meal after oil extraction?
  • The composition of the sunflower meal after oil extraction would depend mainly on the seed variety and the extraction method. Protein and crude fiber are the main compounds in sunflower meal. Plant proteins are economic and sustainable alternatives to animal proteins as functional ingredients in food formulations.
  • Are sunflower seeds a good oil crop?
  • Sunflower seeds are an important oil crop. The by-product of extracting oil from sunflower seeds is sunflower seed meal (cake), which is rich in protein, dietary fiber and biologically active substances, and has a relatively balanced amino acid composition. The crude protein content is 30%-50%. [ 1]
  • 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.
  • What is solvent extraction of sunflower meal?
  • Solvent extraction of sunflower meal was first commercially available, not until two decades now that the use of mechanical pressure becomes more popular with the advent of organic farming and on-farm oil production. Solvent extraction by extrusion reduced the fat content of the processed seeds.
  • What are the applications of sunflower seed byproduct?
  • The applications of sunflower seed byproduct include its transformation into flours/ingredients that are capable of improving the nutritional and functional value of foods. In addition, the protein isolates obtained from sunflower seed byproduct have good technological properties and improve the nutritional value of food products.
  • 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.
