high temperature into smaller molecular products such as free fatty acids and further into secondary oxidation products, like carbonyl com- pounds with a very low molecular weight . Similar increase rate in SV of soybean (195e205 mg/g) and almond oils (172.23e182.75 mg/g) were reported .
Above results showed that tomato seed oil has an excellent physicochemical profile even after 50 h of heating at 180 C and its thermal stability, to some extent, was comparable with that of almond oil or even better than that of soybean oil. Antioxidants were likely the most significant contributor to the high thermal stability of tomato seed oil.
