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.
Smoke point [caution 1] Almond oil: 221 °C: 430 °F [1] Avocado oil: Refined: 271 °C: 520 °F [2] [3] Avocado oil: Unrefined: 250 °C: 482 °F [4] Beef tallow: 250 ...
Clarified butter has a higher smoke point (252 °C or 486 °F) than regular butter (163–191 °C or 325–376 °F), [3] and is therefore preferred in some cooking applications, such as sautéing. Clarified butter also has a much longer shelf life than fresh butter.
The smoke point of an oil refers to the temperature at which it begins to smoke—and also degrade in both quality and taste. Typically, the odor of an oil becomes at least somewhat foul once it ...
The smoke point is marked by "a continuous wisp of smoke". [54] It is the temperature at which an oil starts to burn, leading to a burnt flavor in the foods being prepared and degradation of nutrients and phytochemicals characteristic of the oil. [55] Above the smoke point are flash and fire points. [54]
The TAG flash point tester adheres to ASTM D56 and has no stirrer, while the Abel flash point testers adheres to IP 170 and ISO 13736 and has a stirring motor so the sample is stirred during testing. The flash point is an empirical measurement rather than a fundamental physical parameter.
The flame point of a material is a temperature value at which sustained flame can be supported on the material once ignited by an external source. [28] Once the flame point of a material is reached, it produces enough fuel vapors or oils to support continuous burning.
