Calculator for determining the Decimal Reduction Time (D), the activation energy (Ea), inactivation rate ko for a microorganism at an arbitary temperature given the D and the Z-values at the reference temperature, using the Bigelow and Arrhenius methods

Reference Temperature (Tr)
e.g. (72°C)

Dr value (s) at Tr
Z value (°C) at Tr

Temperature (°C) at T1. May be higher or lower
than the Tr

          

NOTE! The science and mathematics behind this calculator will be described in a tutorial that will be added over the next few months.
