The health benefits and the exploitation possibilities of plant phenolics extracts have been amply demonstrated by numerous studies over the last six decades, and are certainly based, to a large extent, on their antioxidant properties. Polyphenols from grape-derived products have been associated with the prevention of numerous diseases including cardiovascular diseases, neurodegenerative diseases, such as Alzheimer’s, as well as several forms of cancers. In particular, the grape seeds extracts (GSE) have been studied or readily used for many diverse purposes: therapy in several cardiovascular disorders [10]; reduction of oxidative stress and neuronal apoptosis related with diabetes mellitus [11]; protective activity against UVB radiation [12]; protection against early weaned stress syndrome in piglets [13]; fortification of yoghurts [14]; or even reduction of free formaldehyde at appreciable levels in the retanning process of leather [15]. There are also some studies that demonstrate the antioxidant and antibacterial activities of the GSE [16] and also the antiviral effects against a number of viruses [17]. All these varied and attractive uses have been derived in the commercialization of different GSE and, therefore, the occurrence of fundamental concerns in its quality control, already leading to the detection of adulterated products found to contain peanut skin extract [18].
