Factors Influencing Heat Tolerance The smoke point of an oil is not a fixed number; it varies based on several key factors. This occurs when the oil starts to break down chemically, a process that involves the degradation of the fatty acids and the release of free fatty acids, glycerol, and other compounds.

The fatty acid composition also plays a significant role; oils high in saturated and monounsaturated fats are more stable at heat, while those rich in polyunsaturated fats tend to be more delicate.
However, the smoke point is a critical factor that influences not only the flavor and nutritional value of your food but also the safety of your cooking environment.
