Overview of Electric Cooking
The hot air which is emitted during cooking includes substances which have emanated from the foodstuffs themselves, as well as others derived from fats and oils used in the cooking process. Some of these are responsible for typical cooking smells whilst others may appear as smoke. A portion of this smoke may later condense to form greasy deposits of particulate matter in the oven itself and surrounding areas.

In a domestic situation cooking smells are generally more acceptable, however fumes from pyrolytic self-cleaning ovens can be very unpleasant and even dangerous.
