Table 2: Initial (Log(i) CFU/g) and final (Log(f) CFU/g) cell loads of mesophylic bacteria, psicrotrophyc, acid lact bacteria and yeasts in fresh pasta samples analyzed in the final step. The analyses were conducted for no-FilterAir-3 and FilterAir-3 up 13 and 17 days, respectively due to moulds development. FilterMAP-3 and Filter-PS-MAP were monitored up to 45 and 50 days, respectively.
