While this sounds like an impossibly high temperature, know that it doesn’t take long for a fat to reach the flash point once it has reached its smoke point.
What happens when we boil oil?
When heated repeatedly, changes in physical appearance of the oil will occur such as increased viscosity and darkening in colour , which may alter the fatty acid composition of the oil. Heating causes the oil to undergo a series of chemical reactions like oxidation, hydrolysis and polymerization .

The standard deodorization process removes a large portion of the omega-3 fatty acids by turning them into trans-fatty acids (3).
Why you shouldn’t cook with olive oil?
Olive oil has a lower smoke point-the point at which an oil literally begins to smoke (olive oil’s is between 365° and 420°F)-than some other oils. When you heat olive oil to its smoke point, the beneficial compounds in oil start to degrade, and potentially health-harming compounds form.
