Oven Test
Oil samples (250 g) were placed separately in glass dark bottles 300 ml in oven at 60°C and then samples oxidative stability were evaluated at intervals 0, 4, 8, 12, 16, 20, 24, 28 and 32 days. The temperature of 60°C used as a rapid method to simulate the storage in real conditions (Besbes et al., 2004).
