Supercritical CO2 extraction of grape seeds oil: scale‐up

  • How is grape seed oil extracted?
  • For industrial production, cold pressing (screw pressing or continuous mechanical expression) and/or solvent extraction processes are mostly used to obtain grape seed oil. Cold pressing, which applies a lower process temperature and no solvent, is preferred to ensure a higher-quality oil extraction, although the yield is lower (55%–95%).
  • Can we extract oil from grape seeds by cold screw pressing?
  • This study evaluated the physical properties and oil extraction from grape seeds from three white (Welschriesling, Green Veltliner, Hibernal) and two red (Zweigelt and Saint Laurent) must varieties of grapevine by cold screw pressing as the appropriate extraction process.
  • Which process is best for grape seed oil production?
  • Screw pressing is the most efficient process for producing grape seed oil with a high yield, but supercritical CO 2 process permits an increase of polyphenol co-extraction with oil. The GAME process allows extraction of more polyphenols than screw pressing and constitutes an interesting process considering oil yield.
  • How much oil is pressed from grape seeds?
  • The quantity of the pressed oil ranges from 67.5 to 98.5 g.kg⁻¹ and thus depends on the variety. The measured results can be used in commercial practice for optimizing the pressing process for pressing of oil from grape seeds.
