Additionally, the presence of water content or residual solvents can lower the temperature at which an oil begins to degrade. When comparing options, the distinction between refined and unrefined versions is crucial, as the refinement process directly correlates with thermal stability.
Beyond the visible smoke lies the flash point, the temperature at which those vapors can ignite, and the fire point, where the vapor sustains combustion. 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.
