Optimization of oil yield and oil total phenolic content during grape

  • How grape seed oil expression on screw press enables high oil yield?
  • Grape seed oil expression on screw press enables high oil yield. Raw material is the major factor affecting oil expression. Oil polyphenols content is independent of seed polyphenols content. Playing on process parameter an increase in oil polyphenol content can be reached. 1. Introduction
  • 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 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.
