Abstract
Solid by-products from white and red wine industry were subjected to evaluation as potential sources of antioxidant phytochemicals on the basis of their content in phenolics and in vitro antioxidant activity. Furthermore, several other common plant solid wastes, including apple, potato and onion peels, as well as carob pods and olive tree leaves were also considered, in order to carry out a comparative assessment. The results showed that extracts from grape seeds (either white or red) contain exceptionally high amounts of total polyphenols (10.3-11.1% on a dry weight basis), a great part of which is composed of flavanols. Red grape pomace and stems contained app...
