SUSTAINABLE PRODUCTIVE PROCESSES OF POLYPHENOL STANDARDIZED FRACTIONS

This work concerns the planning and the optimization of sustainable productive processes of aqueous extracts from plant tissues and other natural materials, from dedicated crops and wastes of agro-industrial processes. The optimization of extraction, purification and concentration of natural standardized fractions from Cynara, Olea and Sweet Chestnut biomass, have been performed for new and innovative applications in feed, food and agronomics (1,2). Such fractions were analyzed and characterized by HPLC/DAD/ESI-MS methods; moreover, the antiradical/antioxidant activities were measured by DPPH• and Folin-Ciocalteu tests. The results suggested different uses as new natural additives to enhance quality, shelf life and biological value of feed/ food products in synergy or in substitution of the traditional chemicals (3). These results are part of the research activity of the UE Project Life Evergreen (LIFE13 ENV/IT/000461).
