Grape seed oil extraction: Interest of supercritical fluid extraction

  • 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.
  • Is supercritical CO2 a green solvent in grape seed oil extraction?
  • Supercritical CO 2 was considered as a green solvent in extraction of grape seed oil. The effects of different extraction process parameters on oil yield and antioxidant activity were investigated. Extraction optimisation was conducted using response surface methodology (RSM).
  • How is -tocopherol extracted from grape seed oil?
  • For the determination of vitamin E concentrations in grape seed oil samples, α-tocopherol extraction was by methanolic extraction using a known oil concentration according to the method proposed by Capannesi et al. [ 84 ]. After obtaining the extracts, they were dissolved in methanol (2000 µg/mL).
