Original Abstract

For the first time, EPR spectroscopy in combination with UV-VIS was used to possess markers for wines and musts discrimination. The ability of wines to scavenge DPPH, ABTS and TEMPOL radicals as well as their antioxidant capacity towards OH radicals generated directly in the experimental system by chemical reaction in the presence of DMPO spin trap was tested by EPR. Besides that, the content of phenolic compounds (TPC), ferric ions reducing ability (FRP) and the formation of oxidative products (TBARS) was evaluated.
