The smoke point of fats and oils decreases when they are at least partially split into free fatty acids and glycerol; the glycerol portion decomposes to form acrolein, which is the major source of the smoke evolved from heated fats and oils.

A cooking oil's smoke point refers to the temperature when the oil starts to smoke—which it will reach before its boiling point. Heating oils past their smoking point has been linked to the formation of carcinogens and can also create an off, burnt flavor. Knowing the differences among oils and their smoke points is an essential part of healthy coo...
Each oil has a different smoke point, which will vary depending on whether the oil is refined or not and whether the fats in the oil are polyunsaturated, monounsaturated, or saturated fats. At elevated temperatures, oils will change significantly from several chemical and physical reactions including oxidation, hydrolysis, cyclization, isomerizatio...
The smoke that is created once an oil reaches its smoke point is an indication that the fat in the oil is breaking down. As oil is heated, more free fatty acids are produced, which lowers the smoke point. Each time oil is heated, free fatty acids and harmful free radicalsare formed through a process called oxidation—a series of chemical reactions i...
For overall health, the best oils are those high in monounsaturated and polyunsaturated fats. These fats are known to be heart-protective and reduce systemic inflammation in the body. Monounsaturated oils include canola oil, peanut oil, almond oil, olive oil, avocado oil, and high oleic sunflower and safflower oil. These oils tend to have higher sm...
The flavor of oils varies considerably. Most unrefined expeller- and cold-pressed plant-based oils have unique flavors. However, some are stronger than others. For example, nut and seed oils such as walnut, almond, pecan, pumpkin seed, and sesame oil, particularly the "toasted" varieties, have strong flavors that resemble the nut they are derived f...
Choosing the best oil for your recipe will depend on several factors. You want to choose an oil that best fits your health goals, has (or doesn't have) a particular flavor, and has the appropriate smoke point for the cooking style you're using.
Knowing the smoke point of different oils can help inform your cooking and eating choices. Choosing high smoke point oils for frying and other high heat cooking methods is best, while low smoke point oils are best reserved for salad dressing, low heat cooking, and as a finishing oil on completed dishes.
Aug 10, 2020 · Safflower, sunflower, and peanut oil are all tied at 450 degrees. But what sets avocado oil apart from, say, extra-virgin olive oil, which hits its limit at a comparatively chillier 375 degrees? Generally speaking, a cooking oil's smoke point is defined by its refinement.
Oct 19, 2023 · The higher the smoke point, the hotter your oil can be before burning, which can affect the flavor of your dish and its health benefits. Dig into the smoke points of 15+ common cooking oils—including monounsaturated and polyunsaturated fats—so you know what to reach for when deep-frying or sautéing.
Jun 6, 2024 · For instance, the delicate flavor of unrefined almond oil can be ruined by heat, making that a better choice for cold dishes (refined almond oil's smoke point is 420 F and okay for cooking). The high smoke point of coconut oil, on the other hand, makes it a favorite for stir-frying.

Oct 7, 2020 · A high smoke point oil can be loaded with good-for-you mono- and polyunsaturated fats, or it can depend on saturated fats. Palm oil , with nearly 7 grams saturated fat, 5 grams monounsaturated fat, and 1 gram polyunsaturated fat per tablespoon, has a high smoke point of 450 F, per the USDA database.
Feb 22, 2024 · Oils with a lower free-fatty acid content tend to be more stable and have a higher smoke point. Those happen to be, for the most part, plant-derived oils. Most plant oils, if they are not yet rancid, begin to smoke at about 450°F (230°C).
