Grape seed oil extraction: Interest of supercritical fluid extraction

  • How are grape seed oils extracted?
  • Traditionally, grape seed oils are extracted with organic solvents, usually n -hexane in the Soxhlet method, or alternatively through the use of pressing mechanical techniques. Extraction with organic solvents leads to a better extraction yield.
  • 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.
  • Does grape seed oil extraction affect fatty acid profile?
  • Given the unsaturation level of grape seed oils, those compounds are beneficial for oil conservation . The grape seed oil extraction method does not affect the fatty acid profile considering solvent extraction (hexane or petroleum ether) and Supercritical Fluid Extraction (SFE) .
  • What percentage of oil is obtained from grape seeds?
  • From grape seeds, the oil is obtained in a percentage ranging between 8% and 20%. Oil yield depends on environmental factors, cultivar conditions, grape variety, maturation degree of the seeds, extraction technique, and type of solvent used for extraction. From grape seeds, the oil is obtained in a percentage ranging between 8% and 20% w/w [ 28 ].
