Abstract
The frying pan thermal-kimia was a process that produces characteristic of food with the brown colour of golden. One of the parameters of the decline in quality cooking oil is the number of peroxide. During the frying pan, cooking oil will suffer at high temperatures warning 160-1800C in long time.
