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. The main damage is the emergence of a rancid scent while damage other covering elevated levels of free fatty acid, the peroxide, thickness the emergence of oil, the establishment of foam and the dirt on seasoning of material that fried.

Research conducted on eight a penyetan stall areas Mancasan in Yogyakarta obtained the number of the peroxide of 1,10 meq/kg until 5,74 meq/kg. From the result of research conducted on a penyetan stall there are 62.5% penyetan stall peroksida number exceeding the limit of standards and 37,5% still within the limits of cooking oil according to quality standard SNI 7709:2012.
