Technological, sensory and microbiological impacts of reducing sodium content on sausage Consumers are increasingly aware and informed about the relationship between sodium intake and the development of hypertension with subsequent coronary problems. Thus, the food industry has developed numerous products with low sodium content to meet the needs of this new consumer profile. This project studied the technological, sensory, and microbiological impacts on low sodium sausages, with phosphate and potassium chloride added. Evaluations were performed in two meat matrices: a) beef and pork b) mechanically recovered poultry meat (MRPM). In the first stage, emulsions were studied, in which the optimization process used the technique of factorial design with a central composite design, based on Response Surface Methodology, and the independent variables were phosphate, sodium chloride and potassium chloride. This stage was performed in a model system obtaining the mass in a mini cutter with all the ingredients to obtain sausage with varying levels of phosphate, salt (NaCl) and potassium chloride (KCl). In the second stage, the best levels of phosphate and KCl were fixed and sodium chloride remained rated at three contents (1.00 %, 1.30 %, and 1.75 %). The treatments were processed in a pilot plant and the physical/chemical, technological, microbiological, and sensorial analyses were performed. The treatments were monitored over 56 days in vacuum packaged products and stored at 5 ± 2°C in five periods (1, 14, 28, 42, and 56 days). In meat emulsion, the best contents of KCl and phosphate were 0.85% and 0.25%, respectively. In sausage, the treatments with 1.30 and 1.75% NaCl showed the best performance in most analyses, mainly in the sensory analysis. In emulsion of mechanically recovered poultry meat, the best contents of KCl and phosphate were 0.46 % and 0.40 %, respectively, and sausage MRPM treatments with 1.3% and 1.75% NaCl showed the best results mainly in the sensory analysis. The reduction of 1.75% to 1.3% of NaCl represents a reduction of about 25% of sodium chloride and is viable in terms of technological, microbiological, and sensorial aspects.
