Autochthonous white grape pomaces as bioactive source for functional jams

Summary Seeds and skins from grape pomaces of Pecorello and Mantonico cv underwent extraction (ultrasound–assisted or maceration), in order to obtain added‐value ingredients for the production of a functional pear jam. The antioxidant features of the extracts were tested by in vitro colorimetric assays. Among seeds, Mantonico by maceration ( MSC ) showed the best results, as well as Mantonico by ultrasound‐assisted extraction ( MB s) among skin...
