  • What are the health benefits of grape seed oil?
  • Garavaglia et al. [ 45] reported that the anti-inflammatory, antioxidant, cardioprotective, and anti-cancer properties of grape seed oil may be due to linoleic acid, tocopherol, carotenoids, and phytosterols along with polyphenolic compounds such as proanthocyanidins, resveratrol, and quercetin.
  • How does grape seed oil affect adipogenesis?
  • Grape seed oil contains tocotrienols, with significative quantities of α- and γ-tocotrienol (T3), which significantly reduce the expression of mRNA protein, which is crucial for adipogenesis (e.g., PPARγ and aP2); it sharply reduces the pro-inflammatory gene expression (IL-6 and IL-8) [ 62 ].
  • Does grape seed contain phenolic compounds?
  • Previous studies have reported that grape seed (dry base) contains about 35% crude fiber, 29% extractable components, 7–20% oil, 11% protein, 3% minerals and 7% moisture ( Matthäus, 2008), of which oil and protein are found in seed endosperm, while phenolic compounds and crude fiber are mainly present in the seed coat (Fantozzi & Betschart, 1979).
  • What is the value of grape seeds?
  • Grape seeds have an oil content of 12-22% on average, making up 1% to 4% of the weight of the grape. They are also rich in antioxidant compounds, with an oil content varying from 15.5 to 18% in white grapes, and an average of 14,72%. Grape seeds require a more proper analysis of their value.
