Programmable lethality values (F
0
Custom)
F
0
Custom option allows the creation of a lethality table according to the
reference microorganism that the client wishes, to obtain the total lethality
value of the programmed heating treatment.
Note: When editing the program, you must select “F
0
Custom” type to use.
The partial lethality values are obtained by applying the formula:
L = 10 ^ ((T-Tx) / z)
The user must enter the Z and Tx values (unique to each microorganism)
and the custom lethality table will be created. The denition of these
parameters is:
Z: Temperature to reduce a reference microbial population by a loga-
rithmic power.
Tx: Reference temperature.
Most common reference values:
