Interaction
effects were small. The process and recipe variables showed similar effects in morr and salami. In general,
recipes combining high batter levels of salt (NaCl and NaNO2) and glucose along with high fermentation
temperature that gave DFS with low final pH and aw, provided approximately 3 log10 reductions compared to
approximately 1.5 log10 reductions obtained for standard recipe DFS. Storage at 4 °C for 2 months provided
log10 0.33–0.95 additional VTEC reductions and were only marginally affected by recipe type. Sensory tests
revealed only small differences between the various recipes of morr and salami. By optimisation of recipe
and process parameters, it is possible to obtain increased microbial safety of DFS while maintaining the
sensory qualities of the sausages
