The meat used depends on eating habits, customs and the preferences prevailing in the geographical region where the fermented sausage is produced (Table 1). This is usually pork, sometimes mixed with beef (Ordóñez and de la Hoz, 2007 [65]). The fat should be firm, with a high melting point and a low content of polyunsaturated fatty acids, because this causes the fermented sausage to turn rancid more quickly (Frey, 1985 [66]). Mincing of the meat and fat is done at low temperatures (between −5 and 0 °C) to achieve a clean cut and to avoid the release of intramuscular fat from fatty meats, which could cause changes in the color and the drying process during ripening (Frey, 1985 [66]). Once the meat and fat have been comminuted, the starter culture (LAB) and the nitrate reducing CNS, curing salts, additives (nitrates, nitrites, glutamate) and other ingredients (sugars, aromatic herbs and spices) are added. The mixture, after refrigerated storage overnight, is placed in a kneader and stuffed into natural or synthetic casings (Greco et al., 2005 [67]; Ordóñez and de la Hoz, 2007 [65]). The sausages are then ripened
