title: Kinetic expression for the oxidation of linoleic and arachidonic acid esters in their mixed system.
abstract: Two polyunsaturated fatty acids (PUFAs) or their esters were mixed, and their oxidation processes were measured at 65 degrees C and ca. 0% relative humidity. Except when a PUFA ester was mixed with a free PUFA, the oxidation of the less-oxidative PUFA was promoted as its content in the mixture decreased, while the oxidation of the more-oxidative PUFA was delayed with a decrease in its content. A kinetic model is proposed whereby a PUFA acts as the diluent for another PUFA, and the oxidation rate of the PUFA is proportional to the product of the unoxidized PUFA concentration and the sum of the concentrations of the oxidized PUFA and the other oxidized PUFA. This model well expressed the oxidation processes of the PUFAs in their mixed system.
