Valorization of Mexican cabernet sauvignon grape pomace: A source of oil and lipophilic bioactive compounds

This study presents the first analysis of the lipophilic composition of oil extracted from Mexican Cabernet sauvignon grape pomace in Sonora, using ultrasound-assisted extraction. The findings reveal a promising oil yield of 7.52%, with linoleic acid dominating the fatty acid profile at 64.72%. Notably, the oil is rich in bioactive compounds, including tocopherols-tocotrienols (828.83 mg/kg), chlorophylls (32.15 mg/kg), carotenoids (550.04 mg/kg), and sterols (513265.51 mg/kg), highlighting its potential for valorization. These components are recognized for their biological potential, suggesting the grape pomace as a valuable source of high-value lipophilic compounds. This research contributes to the growing interest in utilizing wine industry by-products, advocating for further exploration of grape pomace's applications in food, cosmetics, and pharmaceuticals, thereby supporting sustainable practices in the agricultural sector. image
