This study was proposed following the strategy of the meat sector to reduce sodium intake through applying different salting processes instead of the traditional method. Therefore, the influence of two salting treatments (with 50% and 55% of NaCl replacement by other chloride salts) on the chemical, physicochemical, proteolysis and lipolysis of foal cecinas was evaluated and compared to those cecinas salted with a traditional procedure. Regarding physicochemical parameters, cecinas treated with CaCl2 and MgCl2 increased the lipid oxidation and luminosity, while decreased the redness. The highest contents of protein and the lowest of moisture were obtained in cecinas salted with 50% KCl, while the NaCl content was dramatically reduced by the experimental batches (4.25 and 3.40 g/100 g) in comparison with control samples (7.73 g/100 g). The values of texture (hardness) did not reflect differences among batches. The content of free amino acids increased with NaCl replacement. In fact, data suggests that NaCl had more inhibitory power on the proteolytic enzymes than the other salts. On the contrary, lipolytic phenomenon showed lower differences among treatments (mainly individual PUFA). However, these variations could be related to the higher oxidation observed in the samples with NaCl replacement. On the other hand, the substitution of NaCl by other salts had an important influence in mineral contents. The main objective, which is the reduction of sodium intake, was achieved. Nevertheless, a sensory study should carry out to observe how aforementioned changes affect the organoleptic quality of the final product and the consumer's acceptability.
