  • How much oil is pressed from grape seeds?
  • The quantity of the pressed oil ranges from 67.5 to 98.5 g.kg⁻¹ and thus depends on the variety. The measured results can be used in commercial practice for optimizing the pressing process for pressing of oil from grape seeds. Effect of the number of revolutions of the press spindle for oil yield (%) in seeds of white grape varieties.
  • 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.
  • What is grape (Vitis vinifera) oil?
  • Grape (Vitis vinifera) seeds are obtained from juice or wine production as by-products and considered an environmentally friendly value-added product. The oil from Vitis vinifera seeds is usually extracted by the cold pressing method in order to keep the antioxidant components in the oil with greater oxidative stability.
  • How is grape seed oil extracted?
  • For industrial production, cold pressing (screw pressing or continuous mechanical expression) and/or solvent extraction processes are mostly used to obtain grape seed oil. Cold pressing, which applies a lower process temperature and no solvent, is preferred to ensure a higher-quality oil extraction, although the yield is lower (55%–95%).
