Abstract

Wine pomace is the main by-product generated by the wine industry and poses both environmental and management problems for wineries. However, this winemaking residue has great potential for development of nutraceuticals and functional food ingredients due to its high concentration of grape-derived bioactive compounds (polyphenols, dietary fibre and potassium). Therefore, this PhD thesis has focused on the value-adding of wine pomace as powdered seasonings (a novel alternative for reusing this winery waste), evaluating their health effects against endothelial dysfunction and diseases associated with oxidative stress. The results obtained in studies in vitro, in cell cultures (HUVEC EA.hy926 and HT-29) and in animal models (after acute-and 4-week-supplementation) demonstrate the bioavailability of the new seasonings, mainly the one derived from seedless wine pomace, and evidence their potential beneficial effects against Type 1 diabetes, essential hypertension, and colorectal cancer.
