The degree of rancidity of linoleic acid was examined by an electrochemical redox reaction as a function of time and its kinetic parameters were calculated. The current in the cyclic voltammograms of linoleic acid increased and the potential was shifted to positive values at faster scan rates. The redox reaction of linoleic acid is totally irreversible and can be described as a diffusion-controlled process. From these results, the diffusion coefficient (D_o) of linoleic acid was observed to be 2.61 × 10^-6 cm²/s in a 0.1 M TEAP/DMF electrolyte solution. The exchange rate constant (k^o) was observed to be 9.79 × 10^-11 cm/s. When exposed to air, the development of rancidity affects the oxidation current peak in the cyclic voltammogram.
