Pasteurization Unit Calculator

Read pasteurization units from a holding temperature and a holding time, or turn a target dose back into the minutes you need. Pick the basis first, because the same number means different things on the beer basis and the juice basis.

Both formulas are the published beverage constants: the beer basis references 60 °C with a z-value near 7 °C, and the juice basis references 80 °C with a z-value of 10 °C. The dose that counts is the one measured at the cold spot inside the package, not the temperature of the tunnel water, and no fixed factor converts one basis into the other. Use this calculator to size a tunnel, not to set a scheduled process for your product.
