Abstract
Meat emulsions were made with 50% of phosphate level commonly used in the meat industry, and 0, 25, and 50% NaCl reduction. In addition, salt replacers (KCl, CaCl2, or MgCl2) were used in the formulations with 25 and 50% salt reduction, corresponding to 10 and 20% of the total amount of salts added, respectively. After embedding in casings, the samples were sonicated (25 kHz and 230 W) in an ultrasonic bath (US) at 20 °C for 0, 18, and 27 min. The addition of CaCl2 or MgCl2 impaired (P < .05) the technological properties of the low-sodium samples. Defects caused by NaCl reduction were not eliminated by 18-min US. However, the combination of KCl and 27-min US eliminated the technological defects caused by the 50% NaCl reduction, with no major impact on lipid oxidation during storage (21 days/4 °C), as observed in the TBARS and sensory profile results. Therefore, it is possible to produce low-phosphate and low-sodium meat emulsions.
