A predictive model for microbial growth in beef stored at different refrigeration temperatures in plastic film.

Author(s) : ZARITZKY N., GIANNUZZI L., PINOTTI A.

Summary

Gompertz and logistic models were fitted to experimental counts of microorganisms growing in beef stored at 0, 4, 7, 9 and 10°C. Samples were packaged in polyethylene and in EVA/SARAN/EVA films, being EVA ethyl vinyl acetate and SARAN polyvinyl and polyvinylidene chloride copolymer. Lag phase duration (LPD) and specific growth rate were obtained as derived parameters for lactic acid bacteria Enterobacteriaceae, Pseudomonas sp and psychrotrophic microorganisms. The effect of initial microbial population at different storage temperatures on LPD was analyzed.
