Abstract: The object of the study is the process of oxidation of sunflower oil. The problem associated with the storage and use of oil is the processes of oxidative deterioration. The presence of oxidation products is harmful to human health and undesirable when carrying out chemical reactions. The work is devoted to solving the issue of slowing down the oxidation processes in sunflower oil at different temperatures using effective antioxidant systems. The oxidation process of refined, deodorized, frozen sunflower oil according to DSTU 4492 (CAS number 8001-21-6) was studied. The effectiveness of antioxidant mixtures in various products was determined: mixture of tocopherols, butylhydroxyanisole, eucalyptus extract (in terms of dry matter). Total concentration of the antioxidant mixture for each study was 0.02%. Oxidative stability was assessed during the induction period by differential scanning calorimetry at 70°C. The induction period of the initial oil was 4160 min. The antioxidants with the highest efficiency were determined: mixture of tocopherols: eucalyptus extract (50:50)%, mixture of tocopherols: butylhydroxyanisole: eucalyptus extract in the composition of (66.67:16.67:16.67)%, (16.67:16.67:66.67)%, (33.33:33.33:33.33)%. The corresponding induction periods of sunflower oil were 6034 min., 5887 min., 5878 min., 5895 min. The quality indicators of the oil were determined after 12 months of storage at the temperature of (20 ± 2)°C in the original form and with the addition of rational appropriate antioxidants. Peroxide value of the initial oil was 15.67 ½ O mmol/kg, with antioxidants – 3.78; 4.27; 4.83; 3.57 O mmol/kg, respectively. The results of the work can be used to extend the shelf life of the oil, maintain its regulatory quality indicators, and increase the stability of the oil during heating
