  • Which solvent is used to extract grape seed oil?
  • The extraction of grape seed oil (GSO) for food and cosmetic applications was performed with 2-methyloxolane (2-MeOx) as a green solvent. The oil extraction yield, the tocopherol and tocotrienol content, the fatty acid and polyphenol profiles of the oils were analysed and compared with hexane.‌
  • How is grape seed oil extracted?
  • Extraction. Grape seed oil can be obtained either through direct pressing of whole seeds or from grape seed flour. Conventional methods for oil extraction involve mechanical pressing and solvent extraction techniques.‌
  • Why is pre-treatment important for grape seed oil extraction?
  • Pre-treatment: Since conventional grape seed oil extraction methods present certain limitations regarding extraction yield and solvent use, it is necessary to resort to pre-treatment techniques to improve the extraction yield and the quality of the oil obtained.‌
  • 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) .‌
  • 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.‌
  • Can grape seed oil be used as a food source?
  • Consequently, future research should use grape seed oil from alternative extraction methods, such as ultrasonic extraction, CO 2 supercritical fluids, and pulsed electric fields. Additionally, further studies are warranted to explore the incorporation of this byproduct into novel food sources.
