Reliable determination of the induction period and critical reverse micelle concentration of lipid hydroperoxides exploiting a model composed of pseudo-first and -second order reaction kinetics

A combinational kinetic model was employed for the first time to determine the quantitative values of some kinetic parameters, including induction period (IP), critical reverse micelle concentration (CMC), and maximum attainable concentration of lipid hydroperoxides (PVmax) in a range of edible oils peroxidised at 60 °C. On the basis of the calculated coefficients of variation (CV), the model was able to estimate the kinetic parameters much better than the conventional tangent method. The potency of the combinational kinetic model to provide the values of markedly lower variability caused the small differences among the experimental results to be appeared statistically.
