Pasteurization at 60 °C × 15 minutes — how many PU

One minute at 60 °C is one pasteurization unit (1 PU). So 15 minutes at 60 °C give 15 PU. For other temperatures the calculator applies an exponential relationship.

Frequently asked questions

What is a PU?
Pasteurization unit: 1 PU = 1 minute of holding at 60 °C. Each 1 °C higher gives 1.393 times more PU per minute.

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.
