  • How is oil extracted from rapeseed?
  • Conventionally, oil extraction from rapeseed is achieved by screw-pressing, either by expeller pressing (full-pressing) or by pre-pressing of the seeds, followed by solvent extraction. Oil contents in the resulting press cakes are in the range of 5 %?10 % (full-press) or 15 %?18 % (pre-press) ( Kemper, 2005 ).
  • Does extraction technology affect rapeseed oil functional quality?
  • Extraction technology can influence the vegetable oil functional quality. Polyphenols in rapeseed oil have been proved to be beneficial for cardiovascular health. In this study, we evaluated the effect of extraction methods on the functional quality of rapeseed oil from the perspective of phenolic compounds.
  • Is rapeseed defatting suitable for direct solvent extraction?
  • Due to its high oil content of up to 50 % in the seed, rapeseed defatting is not suitable for direct solvent extraction ( Unger, 2011 ). Conventionally, oil extraction from rapeseed is achieved by screw-pressing, either by expeller pressing (full-pressing) or by pre-pressing of the seeds, followed by solvent extraction.
  • What is rapeseed used for?
  • Every part of rapeseed (flowers, seeds, leaves, stem and root) is used for food, medicinal and cosmetic purposes. The seeds are the most important part as they are used as a source of oil and protein. The content of oils and proteins varies in different lines of rapeseed varieties [ 9 ].
