Peanut oil has a flash point of 600 degrees Fahrenheit. The flash point is the same for both refined and unrefined peanut oil. However, the smoke points of the two oils are different.
Unrefined peanut oil has a smoke point of 320 degrees Fahrenheit, while refined peanut oil has a smoke point of 448 degrees Fahrenheit. The fire point of both oils is 700 degrees Fahrenheit.
Unrefined oil is usually used for gentler cooking, such as sautéing or baking at low temperatures. Refined oil is used for higher-temperature cooking, such as deep-frying. People who have peanut allergies can eat food cooked with refined peanut oil, as it does not cause an allergic reaction.
