Values are estimated parameter values ± standard errors; ^aActivation energies calculated using the original Arrhenius equation ; for a better fitting, some of the inactivation rates Jackson et al. [21] published were not used in this calculation (see ^b and ^c); of the published inactivation rates at 60, 70, 75, 80, 85 and 90°C, the rate at 90°C was omitted in ^b and the rate at 85°C was omitted in ^c. Standard errors could not be calculated. : Temperature [K].
