whereas the production of lipolytic enzymes among staphylococci seems to be a common characteristic (Miralles et al. 1996 ; Coppola et al. 1997 ; Kenneally et al. 1998 ; Mauriello et al. 2004 ; Casaburi et al. 2007 ).
Once free fatty acids are released, they are subjected to oxidative reactions that give rise mainly to aliphatic hydrocarbons, alcohols, aldehydes, ketones,
และ esters, with the latter being produced in the absence of nitrite in the recipe.
Excessive oxidation results in the formation of off - flavors such as rancidity.
The microbiota, through the consumption of oxygen, negatively affects rancidity formation.
