• What is grape seed oil refining process?
  • At present, grape seeds oil refining process is as follows: crude grape seed oil filter, degumming, alkali refining, washing, drying, decoloring, deodorization, finally get the finished product of grape seed oil.
  • What is the techno-economic model of grape pomace biorefinery process?
  • 4. Conclusions The techno-economic model of grape pomace biorefinery process was developed with three scenarios: a single-product scenario (grape seed oil, GSO), a dual-product scenario (grape seed oil and polyphenols, GSO + GSKP), and a whole biorefinery scenario (grape seed oil, polyphenols, and biochar, GSO + GSKP + GB).
  • 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 seed oil?
  • Grape seed oil, a product derived from seed grape pomace, contributes to the recycling and reuse of winery waste, as well as diversifies the range of value-added products of the wine industry.
  • How much oil is produced from grape seeds?
  • This means that one kilogram of seed may produce 67.5 to 98.5 g of oil. 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.
  • Can wet grape pomace be used for oil extraction?
  • However, a previous study suggested that storage of wet grape pomace enables fermentation that leads to structural modification of seeds, which ultimately facilitates oil extraction by pressing and degradation of polyphenolic compounds that are more oil-soluble than native polyphenols ( Rombaut et al., 2015 ).
