Grape Seed Oil Extraction Methods

  • 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.
  • How is oil extracted from grape seeds?
  • For SFE, oil extraction is performed by a continuous flux of CO 2 through the seed bed. The amount of oil extracted then is dependent on the solubility of CO 2 towards oil. Interestingly, uniaxial expression without CO 2 of grape seeds does not allow oil extraction.
  • 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 does grape seed oil cost?
  • The lowest price (10 €/kg) applies to oil for human nutrition where the extraction method consists of solvent extraction at atmospheric pressure. The highest price (30 €/kg) is relevant to herbalist's product, i.e. grape seed oil obtained by cold pressure extraction and sold in 100 ml bottles.
