Definition of Smoke point

Smoke point Definition from Business & Finance Dictionaries & Glossaries
Glossary of petroleum Industry
One of the specifications on jet-engine fuel. Kerosene or jet fuel with a low smoke point is not as desirable as fuel with a high smoke point. Hydrotreating the fuel reduces the smoke or gives it a higher smoke point. This is not a contradiction, as it appears. The high and low smoke points indicate the high and low points on the wick of a testing device made like an old fashioned kerosene lamp. The higher the wick can be turned up while burning the sample of jet fuel without producing smoke, the cleaner burning it is; thus the high smoke point.

In cooking, the smoke point of an oil or fat is the temperature at which under defined conditions enough volatile compounds are emerged from the oil that a bluish smoke becomes clearly visible. At this temperature the concentration of volatile compounds such as water, free fatty acids but also short-chain degradation products of oxidation come up from the oil. The smoke point is not giving the temperature when the oil is decomposed and possibly toxicological relevant compounds are formed.
