The square root autocatalytic equation used to describe the initial process of lipid oxidation was investigated from the viewpoint of the kinetic theory of radical polymerization. The oxidation processes of linoleic acid were investigated from 5 °C to 40 °C, and the oxidation rate constants of the equation were estimated. The Arrhenius plot of the oxidation rate constants of linoleic acid was compared with that of glyceryl trilinoleate, and these were parallel within the investigated concentration and temperature ranges. It showed that the rate constant of oxidation of linoleic acid was faster than that of glyceryl trilinoleate and suggested that the difference was mainly ascribed to the frequency factor.
