Calculating Lethality in MadgeTech 4

Posted on

It is possible to calculate lethality values based on logged temperature data using the MadgeTech 4 software. MadgeTech 4 can calculate lethality using A0, F0, Fd, Fh, and Pasteurization Units (PU).

Lethality can be calculated in a statistics report, or by using a math channel (which allows the lethality value to be displayed as an additional line in a graph report). The instructions for calculating lethality using each of these methods are as follows:

Cycle Detection for Lethality in MadgeTech 4

Posted on

The ability to calculate lethality is a useful feature in the MadgeTech 4 software. MadgeTech 4 contains formulas that allow the user to automatically calculate A0, F0, Fd, Fh, and Pasteurization Units (PU), using either Math Channels or Statistics Reports. Instructions for adding lethality statistics to reports can be found in the following article: Calculating Lethality in MadgeTech 4 | MadgeTech

While Math Channels and Statistics Reports will use the same mathematical formulas to calculate lethality, there is an important distinction in the behavior of the two methods that users should be aware of when analyzing lethality results. Math Channels will automatically detect new lethality cycles when calculating lethality values, while lethality statistics added to a Statistics Report will not.
