In particular, the oils that can be extracted from seeds of different grape varieties own high value, as they contain large fractions of polyunsaturated fatty acids and they can be marketed at relatively high prices. In this context, GSs can be considered a resource instead of waste. Indeed, GS have a great biological potential, which could be exploited by extracting bioactive compounds before addressing it as biomass for energy purposes.

Furthermore, seeds showed the highest antioxidant activity, followed by skin and pulp. Among wine by-products, GSs are the most abundant and represent the portion of the fruit containing the higher concentration of bioactive molecules.
For instance, GS extracts (aqueous or alcoholic) have shown high antioxidant potential, leading to anti-atherosclerotic and anti-inflammatory effects, protection against cellular oxidative damage, modulation of antioxidant enzyme expression and protection against some types of cancer, in both human and animal models. Nowadays, several pharmaceutical preparations, containing GS-derived products, are available and used for their health-promoting properties.
Moreover, grape seed (GS) oil is an excellent cosmetic ingredient for controlling skin moisture, being easily absorbed by the skin. WP revalorization is generally exploited to obtain antioxidants-enriched extracts, which could be combined with other ingredients in functional food matrixes. It includes solid grape parts such as skin, traces of pulp, and seeds with residues of stalk. Wine pomace (WP) consists of the solids remaining after the fermentation of grapes ( Vitis vinifera L.). The recycling of by-products, especially those from plant-based materials, offers important advantages such as their ecologically friendly nature, low cost, availability, reduction of its storage, and elimination of the dismissal costs.
