Effect of sodium chloride replacement on some characteristics of fermented sausages.

The reduction of added NaCl in fermented meat products has been proposed to decrease the amount of sodium in the diet. The effect of substituting NaCl by KCl, potassium lactate (K-lactate) or glycine (0-40%) in some sensory, microbiological and physicochemical characteristics of fermented sausages was evaluated. The sensory effects of substituting NaCl by mixtures of glycine and KCl or glycine and K-lactate was also evaluated. The partial substitution of NaCl by KCl, K-lactate and glycine had little effect on microbiological stability. However, flavour and/or textural defects were detected by sensory analysis with substitution levels of 40% by KCl, 30% with K-lactate and 20% with glycine. The partial substitution (above 40%) of NaCl with different mixtures of KCl/glycine and K-lactate/glycine showed important flavour and textural defects which did not permit an increase in the level of substitution compared to those obtained with the individual components.
