Abstract: Light induced oxidation of the oils of five non-conventional oil sources namely: I. gabonensis (Wild Mango or Dica nut) Seed, D. edulis (African native pear) seed, D. edulis flesh, P. americana (Avocado pear) flesh and T. catappa (Almond) seed were monitored under light of different intensities (Dark, fluorescent light, daylight and direct sunlight). G. Max (Soya bean) oil was used as reference sample for this comparative study. I. gabonensis has the highest stability under the tested conditions. Peroxidation process was accelerated in all the tested oils under direct sunlight. G. max oil recorded the highest peroxide value. All the tested oil samples except I. gabonesis exhibited higher percentage antioxidant activity than the conventional oil from G. max . The strongest effect was obtained for D. edulis flesh oil.
