Abstract 

The aim of this study was to determine the composition and characteristics of red grape seed oils (Vitis vinifera L) from wines with protected denomination of origin (PDO) from Spain. Eight representative varieties of grape seed oils from the Spanish wine Ribera del Duero (Tempranillo), Toro (Tempranillo), Rioja (Garnacha), Valencia (Tempranillo) and Cangas (Mencia, Carrasquín, Albarín and Verdejo) were studied. The oil content of the seeds ranged from 13.89 to 10.18%, and the moisture was similar for all the seeds. Linoleic acid was the most abundant fatty acid in all samples, representing around 78%, followed by oleic acid with a concentration close 16%, the degree of unsaturation in the grape seed oil was over 90%. ß-sitosterol and a-tocopherol were the main sterol and tocopherol, reaching values of 77.31% and 3.82 mg·100 g-1 of oil, respectively. In relation to the tocotrienols, a-tocotrienol was the main tocotrienol and accounted for 13.18 mg·100 g-1 of oil.

Caracterización de aceites de semillas de uvas de vinos con denominación de origen protegida (DOP) de España. El objetivo de este estudio consistió en determinar la composición y características de aceites de semillas de uvas rojas (Vitis vinifera L) de vinos con denominación de origen protegida (DOP) de España. Ocho variedades representativas de aceites de semillas de uvas españolas Ribera del Duero (Tempranillo), Toro (Tempranillo), Rioja (Garnacha), Valencia (Tempranillo) y Cangas (Mencia, Carrasquín, Albarín y Verdejo) fueron estudiadas. Los contenidos en aceite de las semillas oscilaron entre 13.89 y 10.18%, la humedad fué similar para todas las semillas. El contenido en ácido linoléico fué alto en todos los aceites alcanzando un valor del 78%, seguido del ácido oléico con una concentración cercana al 16%, registrando un grado total de insaturación del 90%. ß-sitosterol y a-tocoferol fué el principal esterol y tocoferol, alcanzado niveles del 77.31% y de un 3.82 mg·100 g-1 de aceite respectivamente. En relación a los tocotrienoles, a-tocotrienol fué el mayoritario con un contenido de un 13.18 mg·100 g-1 de aceite.
