3.3. Pressure treatment effects
The effects of varying pressures and temperatures on the microbial
populations of the HHP samples were evaluated correlating
the pressure (P) and temperature (T) independent variables with
the Log cfu/mL survivors (response variable) by a multiple regression
procedure to select the most significant model using the
stepwise backward method. The results were expressed by the
following polynomial equations for Z. bailii (1) and
L. monocytogenes LGB (2), respectively:
