Abstract：A new low-sodium air-dried pork product was made from the meat of mini-pigs by replacement of sodium salt with potassium chloride and calcium lactate with the addition of yeast extract and VC. The quality of the product was evaluated by moisture content, pH value, peroxide value, acid value, color, sensory evaluation, shear force and nuclear magnetic resonance (NMR) properties. The results showed that improved quality and the best tenderness were achieved by partial replacement of sodium salt with 26.7% of potassium chloride and 13.3% of calcium lactate and drying at 20 ℃ and 60% relative humidity for 55 h.
