MICROBIOLOGICAL QUALITY OF SOUS VIDE COOK-CHILL PRESERVED FOOD AT DIFFERENT SHELF LIFE

2010

The effect of three different periods of storage life (0, 15 and 30 days) on the microbiological quality of several foods elaborated with the sous vide cook–chill procedure in a restaurant was studied. These foods are grouped in three categories: meat (breast chicken, foie gras, pork loin and entrecote of veal), fish (codfish, gilt head sea bream, hake and salmon) and vegetable (broccoli, courgette, potato and carrot). Total plate counts in the products studied were in the range of <1.00–3.74 log10 cfu/g. Coagulase negative staphylococci were isolated in the three categories, Enterococcus spp. were isolated from foie gras and Pantoea agglomerans from salmon and carrot. Staphylococcus aureus…
