Smoke point decreases at a different pace in different oils. [10] Considerably above the temperature of the smoke point is the flash point, the point at which the vapours from the oil can ignite in air, given an ignition source. The following table presents smoke points of various fats and oils.
The smoke point of any oil is defined by the temperature at which light blue smoke rises from the surface. The smoke, which contains acrolein, is an eye irritant and asphixiant. The smoke point of oils vary widely. Depending on origin, refinement, age, and source growth conditions, the smoke point for any given type of oil can drop nearly 20 °C.
The smoke point of an oil refers to the temperature at which it begins to smoke—and also degrade in both quality and taste. An oil’s smoke point affects what you’re able to accomplish with it.
The smoke point of cooking oils varies generally in association with how oil is refined: a higher smoke point results from removal of impurities and free fatty acids. [55] Residual solvent remaining from the refining process may decrease the smoke point. [57] It has been reported to increase with the inclusion of antioxidants (BHA, BHT, and TBHQ).
Oils can be heated to temperatures significantly higher than the boiling point of water, 100 °C (212 °F), and used to fry foods. Oils for this purpose must have a high flash point . Such oils include both the major cooking oils – soybean , rapeseed , canola , sunflower , safflower , peanut , cottonseed , etc. – and tropical oils, such as ...
That was followed by stir frying at 26.7, deep frying at 7.7, boiling at 0.7 and air frying at 0.6. Air frying was also the best method for VOCs, measuring at 20 parts per billion (ppb).
They’re popular ingredients because most are neutral in taste and relatively cheap to produce, and they have a high smoke point. They’ve grown steadily in popularity since the late 1800s, ...
