|PMP FAQs - Heat Inactivation Models|
1. Can I use the PMP inactivation models to measure process lethality?
In their current form, PMP models are not suitable for determining process lethality calculation. To make these calculations, it is necessary to know the Z value and Tref temperature, and to be able to calculate F values over a range of changing temperature. We are currently developing a new tool to perform these calculations in future versions of the PMP inactivation models. If you know the valid Z value and Tref for your food product, then you can use these with a spreadsheet tool that can be downloaded from the American Meat Institute's website at www.meatami.org.
