All samples were incubated in an oven at 63 ± 1 C to accelerate the oxidation for 21 days. Samples were analyzed every three days for peroxide value (PV), acid value (AV), and 2-thiobarbituric acid (TBA) value. AV and PV were determined according to AOAC (2005), while TBA was assessed
according to Fernandez-Lopez et al. (2005).
