Why does food cooked with peanut oil stick less than food cooked with sunflower oil?

I tried both peanut oil and sunflower oil on the same food cooked in the same pan and noticed that when cooked with sunflower oil, the food tends to stick to the pan. If I use peanut oil, I have less of a problem.

Can anyone enlighten me as to why both oils react differently even though they are used for cooking food? Both of them have the same smoke point.

Best Answer

I feel the same as you Anderson. I found that too and you just made me to do some research, which I found they have different smoke points.

Also, one of the reasons food stick to the pan is the evenness of the temperature of the pan. If you use a thicker pan or copper pan, the heat will be distributed on the pan more evenly and food will stick less. The higher smoke point of oil makes me to believe the oil helps to distribute heat more evenly.
