- We flag Thermal breakdown (oxidation) at high heat and Rancidity from storage degradation on the Peanut Oil and not on the Coconut Oil.
- The Coconut Oil is cast iron, bare or seasoned with coconut oil where the Peanut Oil is Refined peanut oil, liquid cooking oil, which is most of the difference in these two grades.
