dc.description.abstractThe main objective of this study was to determine the effect of different frying oils and frying methods on the formation of trans fatty acids and the oxidative stability of oils. Sunflower, canola and commercial frying oils, the most commonly used oils for frying potatoes in the fast food industry, were used as the frying medium. The value for total polar compounds was highest when commercial frying oil was used in the microwave oven (22.5 +/- 1.1). The peroxide value, as an indicator of oil oxidation, was lowest for microwave oven frying (2.53 +/- 0.03). The K-232 and K-270 values were 0.41 +/- 0.04 and 0.18 +/- 0.02, respectively, for commercial frying oil in the microwave oven. The lowest free fatty acid content was recorded for the commercial frying oil used in the deep-fat fryer at 190 A degrees C. The highest iodine value was measured for sunflower oil used in the deep-fat fryer (148.14 +/- 0.07), indicating a greater degree of unsaturation. The lowest trans fatty acid value was recorded for sunflower oil in the microwave oven (0.17 +/- 0.05), with a higher overall amount of total trans fatty acids observed for oils after frying in the electrical deep-fat fryer compared to the microwave. Sunflower oil was favourable for both frying methods in terms of the trans fatty acid content.
