DSC (Differential Scanning Calorimetry) is one of the thermo-analytical methods, which allow to measure parameters of oxidation with no chemical substances used. The objective of this study was to measure thermo-kinetic parameters of fat extracted from corn grains, as well as to research into oxidative stability by a differential scanning calorimetry test. Whilst carrying out the research, a dynamic option of the apparatus was used, and the following rates of heating the samples were applied: 4 K/ min, 5 K/min, 7,5 K/min, 10 K/min, 12,5 K/min, and 15 K/min. The values of activation energy and of pre-exponential factor were calculated by the Ozawa-Flynn-Wall method. Fat from corn grains is characterized by a high oxidative stability and high starting (onset) temperatures of oxidation process. The value of activation energy at the maximum temperature is lower than at the onset temperature. The same regularity was found in the case of pre-exponential factor.
