food.heat-transfer-pasteurization Calculator
Calculates the time required to achieve a target log reduction of pathogens at a given temperature using pasteurization D-values and z-values. The regulatory standard for HTST milk pasteurization is 72°C for 15 seconds, achieving a 5-log reduction.
Inputs
Log Reduction
Reference formula or conversion factor shown for context.
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).
Process Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
