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?
