food.pasteurization-f-value Calculator
Calculates the F-value — the equivalent minutes at 121°C that a given heat process delivers to food — for canning and retort sterilisation. An F0 value ≥3 is the regulatory minimum for low-acid canned foods (botulism safety).
Inputs
Temperature C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Time Seconds
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Z Value C
Reference formula or conversion factor shown for context.
Reference Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Results
pasteurization F-value (s at 60°C)
The computed numeric or monetary value.
log reductions achieved
Sample size or count used in the calculation.
lethal rate L
The value at the specified point or condition.
