Luisa Erler, Katrin Böhm, Volker Catalano, Assunta Simone, Rossella Palozza, Paola Tomato peel Tomato powder Radiation Lycopene antioxidant activity Lycopene changes 7 páginas, 5 figuras, 1 tabla Tomato powder (TP) and dry tomato peel (DTP) have been previously used in our laboratory as a source of lycopene to manufacture meat products ready-to-eat (RTE) submitted to E-beam irradiation with good technological and sensory results. Present work describes the studies performed in order to investigate the effect of radiation on chemical changes and antioxidant properties of lycopene. DTP and TP were irradiated (4 kGy). Changes on lycopene were analyzed by HPLC; inhibition of reactive oxygen species (ROS), possible modulation of mitogen-activated protein kinases (MAPK) cascade, nuclear factor κ-light-chain-enhancer of activated B cells (NP-κB) activation and expression of proteins involved in oxidation stress were analyzed in RAT-1 fibroblasts cell culture. Radiation reduced the content of all-E-lycopene and increased (Z)-lycopene, lycopene isomerization, and degradation being higher in DTP than in TP. E-Beam treatment increased the antioxidant ability of both DTP and TP in inhibiting spontaneous and H2O2-induced oxidative stress in cultured fibroblasts. Antioxidant activity was higher in DTP than in TP samples Peer reviewed 2014-03-14T08:04:22Z 2014-03-14T08:04:22Z 2014-01-29 artículo http://purl.org/coar/resource_type/c_6501 Journal of Agricultural and Food Chemistry 62 :1557-1563 (2014) 0021-8561 http://hdl.handle.net/10261/93613 org/10.1021/jf4048121 en dx.doi.org/10.1021/jf4048012 none American Chemical Society |
