Before using oil for cooking every cook should be aware of several characteristics of the oil. Some believe that the boiling point of corn oil is one of the important features of this oil. As Wikipedia states a boiling point is the temperature when the oil starts boiling and turns into a vapor. In fact, before boiling any oil begins to smoke. This moment is called the smoke point and it is a much more important feature of any oil. If the oil reaches this temperature the oil emits smoke, its fatty acids break down and free radicals are accumulated in the oil. Dietologists warn against consuming the oil after it starts smoking. It becomes dangerous for the health and can cause cancer. That’s why it is the smoke point of oil we should know before applying oil for cooking.

Corn oil is derived from the germ of corn. The oil is degummed, refined and deodorized. The boiling point of corn oil is high It is not easy to measure the boiling point of the oil. And it is not necessary. We should know the smoke point of the oil not to overheat it. The smoke point of corn oil is 450 degrees Fahrenheit.
