When heated to high temperatures, oil undergoes a literal and chemical change. Both the kind of oil and the temperature play a role in the rate of the breakdown, which in turn determines the overall creation of harmful chemicals. The degradation of the oil first leads in the formation of hydroperoxides, which is followed by an increase in the levels of aldehydes.
What happens if cooking oil overheats?
Cooking oils can be hazardous if they are overheated, despite the fact that different oils have different heat tolerances. If that level is exceeded, the oil not only starts to lose its nutritional value and flavor, but it also releases harmful gases and compounds that are detrimental to your health that are called free radicals.
Can you use oil that has been overheated?
More than just a burned flavor is transferred to meals when they are cooked in oil that has been heated past the threshold at which it begins to smoke.

What oil is toxic when heated?
These include oils such as soybean, corn, canola, sunflower, and safflower. Other examples include safflower. These fats are inherently unreliable since there is no cohesive force holding them together. When heated, these substances can release larger quantities of free radicals than normal due to their inherent instability. In addition, as was said before, we want to limit the amount of free radicals that are present in our bodies.
Is reheating oil carcinogenic?
The frequent warming of frying oil causes a change in its composition and causes the production of a molecule known as acrolein, which is poisonous and has the potential to cause cancer.
