The microbial safety and
storage stability (shelf-life) of fermented sausages depend on
combined effects of multiple antimicrobial factors acting in the
sausage matrix: acidity (low pH), low water activity (aw) due to
added salt and drying, nitrites, and LAB due to their competitiveness
and production of inhibitory compounds such as bacteriocins
(Lücke, 2000).
