摘要：This study examined the effect of degumming process on antioxidants properties and oxidative stability of six non- conventional oils in Nigeria extracted from the seeds and flesh of Terminalia catappa (seed), Irvingia gabonesis (seed), Glycine max (seed), Persea americana (flesh), Tithonia diversifolia (seed), and Dacryodes edulis (flesh). DPPH scavenging activity of the oils decreased after degumming except for D. edulis with increased DPPH scavenging activity. Similarly, total antioxidant capacity (TAC) decreased for G. max, T. diversifolia and I. gabonensis after degumming but increased for T. catappa, P. americana and D. edulis. The degummed oil showed high peroxidation under the different light intensities (under direct sunlight, fluorescent light, and daylight) except I. gabonesis oil (PV: 5.7 meq/kg) and T. catappa oil (PV: 11 meq/kg) with improved stability in the dark for the period of study (84 days).
