  • 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 %¨C10 % (full-press) or 15 %¨C18 % (pre-press) ( Kemper, 2005 ).
  • What is the solvent-free defatting of rapeseed?
  • The solvent-free defatting of rapeseed was studied by Wäsche (2002) using wet crushing followed by aqueous extraction. For the combined process of isolating both oil and protein, the author reported maximum yields of 72 % and 88 %, respectively, using high-pressure homogenization for cell disruption.
  • Which raw material is best for rapeseed protein extraction?
  • Tzeng et al. (1990) carried out a detailed study to compare rapeseed protein extraction from a variety of different raw material qualities. Using pH 11¨C12 for extraction, the highest isolated yield was achieved from Soxhlet-defatted meal, at 75.4 %.
  • Can rapeseed oil be used in a pressure system?
  • The system is, however, limited in its application to products with a low oil content. Seeds with a high oil content (>40%), such as rapeseed and sunflower seeds, do not usually allow sufficient pressure build-up in the units to achieve similar effects as seen with soybeans [ 20 ].
  • How much oil is extracted from rapeseed meal compared to hexane?
  • The extraction yield with 2-MeOx was comparable to that with hexane on a laboratory scale (45.96 and 46.34 g/100 g DM, respectively). Using the 6-litre pilot percolation extractor, the percentage of residual oil in the rapeseed meal was 1.8% for hexane and 0.8% for 2-MeOx [ 76 ].
  • Does pre-treatment with PEF increase rapeseed oil extraction yield?
  • Guderjan et al. [ 31] showed that pre-treatment with PEF increases the rapeseed oil extraction yield and the concentrations of total antioxidants, tocopherols, polyphenols and phytosterols in the oil.
