The aim of the paper was to find the origin of odorous compounds in traditional Friuli sausages produced by a small factory in the Udine-San Daniele area. The sensorial alteration (mephitic type) of dry salami was due to the pork meat with a pH over 6.2 (DFD - Dark, Firm, Dry type) and to an anomalous fermentation of Lactic acid bacteria/enterococci, CNC (Coagulase negative cocci), and enterobacteriaceae. These bacteria have produced hydrogen sulphur and metanthiol, which are responsible for the mephitic aroma of the sausages.

Abstract
The aim of the paper was to find the origin of odorous compounds in traditional Friuli sausages produced by a small factory in the Udine-San Daniele area. The sensorial alteration (mephitic type) of dry salami was due to the pork meat with a pH over 6.2 (DFD - Dark, Firm, Dry type) and to an anomalous fermentation of Lactic acid bacteria/enterococci, CNC (Coagulase negative cocci), and enterobacteriaceae. These bacteria have produced hydrogen sulphur and metanthiol, which are responsible for the mephitic aroma of the sausages.File in questo prodotto:
