dc.description.abstract This study has been conducted to explore the effect of frying on the physical and chemical characteristics of corn and sunflower oils. For the purpose of this study, corn and sunflower oils and potatoes were obtained from the local market; the oils were reused for frying five days consecutively. After each frying process a sample of oil was taken daily after it cools. The samples were physically and chemically tested, all the physicochemical characteristics were changed. The colour of corn and sunflower oils increased from 0.9 to 6.4 and from 0.4 to 5.1, respectively. Whereas the refractive index of corn and sunflower oils increased from1.4750 to1.4820, and from 1.4750 to 1.4810, respectively. On the other hand, the viscosity of corn oil and sunflower oil increased from 28.7 to 31.0, viscosity of sunflower oil increased from 28.7 to 31.0. The free fatty acids increase in corn oil from 0.125 to 200.0 whereas in sunflower oil they increased from 0.110 to 0.150. In case of peroxide value in both oils the study showed that it was not constant. It worth mentioning here that the frying process followed in this study is the same that is usually used at homes. en_US
