How It Works

Calculate equivalent pasteurization treatments using time-temperature combinations based on z-value and D-value for target pathogens in thermal processing

Each component has a specific meaning:

  • Time-temperature combinations based on z-value — The time-temperature combinations based on z-value recorded for the patient or scenario being assessed.
  • D-value — The d-value recorded for the patient or scenario being assessed.

Note: Interpret the pasteurization equivalence result against the clinical thresholds and context described above.

How to Use

Enter the time-temperature combinations based on z-value, D-value for the patient or scenario you are assessing. Calculate equivalent pasteurization treatments using time-temperature combinations based on z-value and D-value for target pathogens in thermal processing. Use the pasteurization equivalence result to inform your clinical assessment.
