Evoluzione della popolazione microbica del cavolo cinese di IV gamma in atmosfera modificata

The aim of this present work was to monitor the dynamics of microbial population in minimally processed chinese cabbage samples, subjected to clorine, ascorbic and lactic acids washing procedures, packaged in a modified atmosphere (MAP) using different O2 and CO2 concentrations and stored at 4°C for 12 days. Plating counts using different media highlighted that in general all samples showed microbiological values within the microbiological criteria established, except for psychrotrophic bacteria. The technological procedures used in the present study have confirmed that the washing treatment with ascorbic acid/chlorine solution and the modified atmosphere packaging are recommended requirements to guarantee the shelf-life of minimally processed chinese cabbage.
