| Nine batches of cooked sliced emulsion type sausages, produced from organic meat with or without the use of nitrite, were packed under N2/CO2 (7:3) and vacuum, respectively, and stored at 8°C.

The sensory profile showed an increase of the sour and rancid aroma and flavour, in parallel to the growth of these microorganisms. These changes were more pronounced in the batches prepared without nitrite. Spots of red discolourations were occasionally observed... |
