Effect of modified atmosphere packaging at abuse temperature on the growth of Penicillium aurantiogriseum isolated from fresh filled pasta

The growth rate and lag phase was modelled as function of CO2 concentrations using a polynomial model equation. The estimations of growth rate and lag phase were in excellent agreement to the experimental results (R2=98.5; RMSE=0.01; P<0.01). The time to reach a colony diameter of 3 mm was also calculated.
