Vegetable oils are currently not only one of the most popular foods in the world, having a reputation for being healthy, but also the main source of unsaturated fatty acids, which prevent numerous cardiovascular and other diseases. In order to study the depth of oxidative changes in the chemical composition of the fatty acid phase in real technological processing processes and the preparation of culinary dishes using vegetable oils, the peroxide, acid, anisidine, Totox, thiobarbituric numbers for vegetable oil were studied under various conditions of model conditions: cooking (temperature 95-100 °C, processing time 30 min), frying (temperature 195-200 °C, processing time 15 min), short-term heating (microwave heating power 90 W, processing time 2 min), breaking the condition ovy storage (temperature 35-40 °C, and treatment time 3 to 7 days). With a comparative description of oxidative processes in coconut, palm, and sunflower oil, it was established that sunflower oil is prone to deep oxidative damage processes. A high propensity to increase the studied parameters was found for all treatment options, which indicates a deep occurrence of oxidative processes in vegetable oils. A particularly large effect, accelerating the oxidation of unsaturated fatty acids of sunflower oil, is observed in the case of storage at elevated temperatures and microwave heating. Based on these data, recommendations are made on the need to use natural antioxidants in the processing of vegetable oils, food production using vegetable oils, cooking culinary dishes, in the formulation of which vegetable oils are present.
