Bacteriobiota and chemical changes during the ripening of traditional fermented Pirot ironed sausage

One of the typical products in Serbia is the flat so-called Pirot ironed sausage (Pis), an unprocessed product, without preservatives, heat treatment, and exposure to smoke. It is a famous specialty traditionally made of top-quality meat mixed with natural spices, without additives or starter cultures. For the production of the Pis, several carefully selected pieces of non-fat goat, lamb, beef, and even horse or donkey meat types are used.
