Physicochemical properties and flavour profile of fermented dry sausages with a reduction of sodium chloride

The objective of this study was to evaluate the effects of NaCl reduction (2.5% 2.0%, 1.5% and 1.0%) on the bacterial growth, physicochemical characteristics, flavour profile and sensory traits of fermented dry sausage. The moisture content, water activity and lactic acid bacteria count increased as the NaCl level decreased (P < 0.05), contributing to decreases in pH (P < 0.05). A total of 50 volatile compounds were identified, and increases in...
