Toasted sesame oil has a stronger flavor and is often used as a finishing oil, added to dishes just before serving to preserve its flavor and aroma. Plain sesame oil, on the other hand, has a milder taste and is sometimes used for cooking.
Nutritional Profile of Sesame Oil
Sesame oil is predominantly composed of polyunsaturated fats, with a significant amount of monounsaturated fats and a smaller proportion of saturated fats. It is also a good source of antioxidants, including sesamin and sesamolin, which have been linked to various health benefits, such as reducing inflammation and improving heart health. However, the high polyunsaturated fat content in sesame oil makes it prone to oxidation, which can lead to the formation of harmful compounds when heated.
Smoke Point: The Critical Factor
The smoke point of an oil is the temperature at which it begins to break down and smoke. This factor is crucial when choosing a cooking oil, as heating an oil beyond its smoke point can lead to the formation of toxic compounds and a loss of nutritional value. Sesame oil has a relatively low smoke point, ranging from 410°F (215°C) for plain sesame oil to around 420°F (220°C) for toasted sesame oil. This low smoke point makes sesame oil less suitable for high-heat cooking methods, such as frying, sautéing, or baking, as it can easily exceed its smoke point and become damaged.
