Reducing 50% sodium chloride in healthier jerked beef: An efficient design to ensure suitable stability, technological and sensory properties

Abstract

The objective of this study was to evaluate the effects of the partial replacement of NaCl by blends of KCl and CaCl₂ on the physicochemical, microbiological, and sensory properties of jerked beef. For that, in the dry and wet salting stages, 50% NaCl of the control treatment (FC1) was replaced by 50% KCl (F1), 50% CaCl₂ (F2), and a blend containing 25% KCl and 25% CaCl₂ (F3) at equivalent concentrations based on the ionic strength. All reformulated treatments presented a significant sodium reduction when compared to the control (27.57% F1, 41.59% F2, and 36.74% F3). The CaCl₂ blends resulted in final products with bitter taste and rancid aroma accompanied by a higher TBARS and shear force and lower a* values (P < .05). The substitute salts did not affect the microbiological stability (P > .05). The present results demonstrate that adding 50% KCl may be a good strategy to reduce sodium in jerked beef.
