DT‐values and 95% CI for a predicted individual value reported. zT‐values obtained using the slopes of thermal inactivation lines constructed in the study and their 95% confidence limits |
CI: confidence interval; DT: decimal reduction time at a certain temperature; zT: thermal resistance constant.
Calculated from digitalised graphs.
