The thermal decomposition process of the oils occurred in three steps, due to polyunsaturated, monounsaturated and saturated fatty acids decomposition, respectively. Kinetic parameters were obtained using Coats-Redfern and Madhusudanan methods and presented good correlation. According to activation energy of the first thermal decomposition step, the following stability order is proposed: corn (A) > rice > corn > soybean > sunflower (A) > canola (A) > sunflower > olive.
