This study was conducted to determine the effects of partial replacement (40.0%) of sodium chloride by potassium chloride, potassium lactate and calcium ascorbate on quality characteristics of cooked pork ham during cold storage. The cooked pork hams with partial replacement of sodium chloride by potassium chloride and potassium lactate had lower lightness (L*) and higher bitterness than others (p <0.05). However, redness (a*), yellowness (b*) and overall acceptability of sensory properties were not different among the treatments (p >0.05). The partial replacement of sodium chloride by all substitutes leads to increase tenderness (p <0.05). There are no problems in microbiological stability and lipid oxidation of cooked pork hams with 40% replacement of sodium chloride by potassium chloride, potassium lactate and calcium ascorbate during cold storage. Therefore, it is possible to use potassium chloride, potassium lactate and calcium ascorbate as partial substitutes of sodium chloride in cooked pork ham.

김치의 보존성과 품질향상에 미치는 calcium lactate와 calcium acetate의 영향을 조사하기 위하여 calcium lactate와 calcium acetate를 0.5:0-0:0.5의 비율로 혼합하여 김치에 0.5%로 첨가, 1에서 숙성시키는 동안 pH, 산도, 칼슘함량, 조직의 광학현미경 관찰 및 관능검사를 행하였다. 그 결과 calcium lactate : calcium acetate가 0.4 : 0.1, 0.3 : 0.2,
