Frequently asked questions

Why does time fall quickly as temperature rises?
Lethality grows exponentially: every few degrees speed up microbial kill many times over.

The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
