Fig. 3. Evolution of counts of aerobic mesophilic flora (round symbols) and lactic acid bacteria (triangle symbols) (log10 cfu•g−1) in samples conditioned under ambient air (a) and modified atmosphere (b) (modified atmosphere packaging (MAP): 50%CO2–50%N2 or air). Plain symbols represent AMC counts of non-pressurized samples and open symbols are used for pressurized samples (500 MPa; 5 min). Results represent means of triplicates and bars, standard errors. The dashed lines represent the detection limit of bacterial counts (i.e. 10 cfu•g−1).
