Dear Oilogists,

" Oil for heat and Butter for flavour "..that's what I was taught !

See these lovely oils here ?


[attachment=3101]

Nice eh ?


Olive Oil I know  (Well, I'm pretty sure) is an oil that has quite a low boiling temperature in the pan...so...can you give me some indications of how hot oils get in the frying pan ?


Sunflower ?
Olive ?
Lard ?
palm oil ?
soybean oil ?
rapeseed Oil ?
Sesame seed Oil ?

Do they all vary by a large degree if kept at the same heat setting on the stove ?


Thank Ewe

They get pretty hot. The Maillard reaction, discovered by French chemist Louis Camille Maillard about 100 years ago, kicks in at more than 148 degrees C. This is the reaction between sugars and proteins, the result of which is the lovely brown colour of cooked food. This reaction is responsible for a good proportion of the tasty flavours and smells we associate with cooked food. Since frying produces a lot of these flavours, the temperature must exceed 150 C, and probably exceeds 200C at times.

Olive doesn't go very hot.

Doesn't it depend how high you turn the gas up?  [:P]

Incidentally, the settings on our fryer start at 150C

I give our chips their second frying 2 mins at 190C - in either light olive or sunflower oil; can get a bit of smoke sometimes though.

You're not saying you have put Olive Oil in your deep fat frier? Next, you'll be putting super unleaded in your car.

The smoke point for olive oil is 190C.

How hot they will get essentially depends on how far you turn the gas or electrtic heating up.
OTOH how hot you want them to get is another matter.
Butter contributes to the taste, but it scorches if overheated.
Some fats like lard will put up with higher temperatures. That means faster cooking which is good for some things.
Please disregard all previous signatures.
