Resumen

The present study evaluated the proximate composition, the nutrition indexes of lipids and the presence of biologically active compounds in the flour of bagasse from grapes cultivated by conventional (CC) and organic (OC) methods. CC flour had high percentages of proteins, lipids, calories and saturated and monounsaturated fatty acids. On the other hand, OC flour had higher percentages of polyunsaturated fatty acids, especially omega-3 and omega-6 fatty acids, ash and carbohydrates. The results demonstrated good nutritional potential for flour from grape bagasse and justified technological applications of the byproduct as a functional ingredient in the formulation of food products. Los alimentos producidos con el uso de los subproductos, caracterizados por propiedades bioquímicas y fisiológicas beneficiosas para salud y porque evitan una mayor degradación del medio ambiente, han sido bastante discutidos y valorados. El estudio evaluó la composición proximal, perfil de ácidos grasos, los índices de la calidad nutricional de los lípidos y la presencia de compuestos biológicamente activos en las harinas de orujo de uvas a partir del métodos de cultivo: convencional (CC) y orgánico (CO). Los resultados mostraron que la harina CC mostró altos niveles de proteínas, grasas, calorías, ácidos grasos saturados y monoinsaturados, mientras que el contenido en ácidos grasos poliinsaturados, especialmente omega-3 y omega-6, los carbohidratos y las cenizas fueron mayores para la harina CO. Estos resultados indican un bueno potencial nutricional de la harina obtenida de orujo de uva, así justifican la aplicación tecnológica del subproducto como un ingrediente funcional en la formulación de productos alimenticios.
