Trans fats are popular owing to their low cost and potential to increase the shelf life of processed foods but also associated with various risk factors. The present study is focused on the impact of oil processing, like frying, on the formation of trans fats in commercially available edible oils. Scanning electron microscopy was carried out to observe the structural changes in the frying material. The physicochemical analysis of processed edible oils was carried out, while the formation of trans-fatty acid (TFA; elaidic acid) during processing was measured by gas chromatography-flame ionization detector (GC-FID). Furthermore, levels of TFA, i.e., elaidic acid, were found higher in oil samples with potatoes than the oil samples without potatoes. It is proposed that trans fat content could be reduced by using the high-quality frying medium as well as avoiding the repeated frying in order to improve the quality and nutritional value of the diet and avert risk factors.
