This study investigates the effect of UV-A irradiation on amino acids, lipid peroxidation in WM and determines the effectiveness of UV-A treatment of WM against aflatoxin-induced cytotoxicity. A secondary objective is to assess the changes in the volatile content of UV-A exposed WM and investigated if UV-A exposure of WM samples containing AFB1 and AFM1 could alter the aflatoxin-induced apoptosis in human hepatoma (HepG2) cells.
