Simplified version of the Dairy Science and Food Technology F and P value calculator.
This is a simplified version of the Dairy Science and Food Technology F and P value calculator. To use you must first generate a simple data input grid by selecting the time interval, in minutes, used for your temperature measurements e.g. 3 minutes and the total process time e.g. 120 minutes. Adjust the reference temperature and Z-value and add your temperature-values. The software will then calculate the equivalent lethality at the reference temperature and using the Trapezoid rule, the cumulative lethality for your process. Note a D-value is not required for F or P calculation.
