Definition
The D-value is a number given to characterize a process to achieve inactivation of 90 % of a population of the test microorganism under stated conditions (temperature, pressure, etc.). This value could be a dose or a concentration for a drug, a time in minute, hour, or day for DHMR, or pasteurization, a dose for sterilization using ionizing radiations (i.e., γ-ray).
