Evaluation of the pressing process during oil extraction

  • 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 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.
  • What is oil extraction yield?
  • Oil extraction yield was defined as the ratio of the mass of clarified oil recovered from extraction to the mass of oil originally present in the seeds for screw pressing experiments, and as the ratio of the mass of the oil phase recovered from SFE or GAME experiments to the mass of oil originally present in the seeds. 2.2.3.
