Description of the cooperation project:
By-products from the wine industry can be an alternative source of dietary fiber, natural antioxidants or bioactive peptides. Starting from this premise, seven different types of wine by-products were characterized, those with the highest content of dietary fiber, polyphenols and protein were selected for the subsequent search for biological activities.
As main results: (1) An extract with antioxidant activity was obtained; (2) An ingredient with 80% insoluble dietary fiber and 20% soluble dietary fiber was obtained; (3) A protein extract with antihypertensive activity was obtained.
