Questions and Answers - Smoking Points of Cooking Oils

Not all fats are the same. Following are some basics on the various types of fats to help you make sense of what is best for your own body.

Saturated Fats:

Saturated fats are mainly animal fats and are solid at room temperature. These fats include butter, cheese, whole milk, ice cream, egg yolks, lard and fatty meats. Some plants fats are also high in saturated fats such as coconut oil and palm oils. Saturated fats raise blood cholesterol more than any other food you eat. By using the right oils and fats for the right reasons, you can preserve the healthful benefits. Your foods will not only taste their best, but also be healthy.

Unsaturated Fats:

These fats can come from both animal and plant products. There are three (3) types:

Monounsaturated Fats - Usually come from seeds or nuts such as avocado, olive, peanut, and canola oils. These fats are liquid at room temperature.

Polyunsaturated Fats - Usually come from vegetables, seeds, or nuts such as corn, safflower, sunflower, soybean, cotton seed, and sesame seeds oils. These fats are liquid at room temperature.

Trans Fatty Acids - Trans fats are produced when liquid oil is made into a solid fat, such as shortening or margarine. This process is called hydrogenation. Trans fats act like saturated fats and can raise your cholesterol level.

Based on the above classification, the ideal cooking oil should contain higher amounts of monounsaturated and polyunsaturated fats, with a minimal or no saturated fats and trans fats.

Different fats and oils have different uses. Each performs best within a certain range of temperature. Some are made for high heat cooking, while others have intense flavors that are best enjoyed by drizzling directly on food.

The smoke point of an oil or fat is the temperature at which it gives off smoke. The smoke point of oil depends to a very large extent on its purity and age at the time of measurement.

Fats or Oils	Cooking Uses	Type of Fat	Smoke Point °F	Smoke Point °C
Almond Oil Has a subtle toasted almond aroma and flavor.	Used in sauté and stir fry of Oriental foods.	Monounsaturated	420°F	216°C
Avocado Oil Vibrant green in color with a has a soft nutty taste and a mild avocado aroma. This oil can be used for very high temperature applications.	Stir frying, searing	Monounsaturated	520°F	271°C
Butter Whole butter is a mix of fats, milk solids, and moisture derived by churning cream until the oil droplets stick together and can be separated out.	Baking, cooking	Saturated	350°F	177°C
Butter (Ghee), Clarified Butter Ghee has a higher smoke point than butter since clarification eliminates the milk solids (which burn at lower temps).	Frying, sauteing	Saturated	375-485°F (depending on purity)	190-250°C (depending on purity),
