The 50% reduction of NaCl in F1 caused a decrease in the parameters. This behavior indicates a loss of rigidity due to the weaker intermolecular interaction formed in the protein network, which is probably caused by an ion charge reduction. However, the incorporation of potassium in F2 (50% NaCl and 50% KCl) and F4 (50% NaCl, 25% KCl and 25%
CaCl2) increased the viscoelastic parameters, demonstrating a symbiotic effect between sodium and potassium in the formulations of the dry fermented sausage, thus resulting in tougher samples.
