Abstract
At each of the tested temperatures, RR for both O2 and CO2 showed an exponential increase over time. This effect was enhanced with temperature. It was further observed that both the initial RR and reaction rate constants changed with temperature according to an Arrhenius-type equation with identical activation energy. This effect was incorporated in the primary model and the fit of the global model to experimental data was good (R2â¯=â¯0.94), with normal distribution of the residuals and correlation coefficients between the model constants below 0.85. Results helped establish a global mathematical model describing RR dependency on temperature over a period of storage time after dicing onions that will allow for a proper package design of this product.
