The main effect of MAP was the increase in lag phase from 4
to 8 days, for lactic acid bacteria, psychrotrophic and mesophilic aerobes. The respective growth rates
were similar to those observed with PUA. In addition, MAP inhibited Pseudomonas growth during 18
days. Considering 6 log CFU g1 as maximum tolerable microbial load, the calculated values of shelf life in
BP, PUA and MAP were 6, 7 and 12 days, respectively, when considering the fastest growing
microorganisms.
