WebSo, F0 = (0.21min.) (1 – (-11)), or 0.21 x 12 = 2.52 minutes. Simply put, (D-value at 250℉) x (12) results in a 12-D process. 6.6 The Z- value: The Z-value is the increase or decrease in temperature required to reduce or increase the decimal reduction time by one decimal. It is a measure of the change in death rate with a change in temperature. In microbiology, in the context of a sterilization procedure, the D-value or decimal reduction time (or decimal reduction dose) is the time (or dose of an antimicrobial drug) required, at a given condition (e.g. temperature) or set of conditions, to achieve a log reduction, that is, to kill 90%(or 1 log) of relevant microorganisms. A D-value is denoted with the capital letter "D". Thus, after an exposure time of 1 D, only 10% of the organisms originally present in a microbial colony would re…
