Abstract: In order to reduce the sodium content without affecting the flavor of dry cured Bacon,the effect of KCl(0~40%) and potassium lactate(0~25%) as NaCl partial substitutes in dry cured Bacon on basic physical and chemical indexes and some sensory parameters(fuzzy mathematic sensory evaluation) were studied; the orthogonal experiments of three factors and three levels were carried out with KCl substitution,potassium lactate substitution and curing time.The results showed that there were no significant differences in the basic physical and chemical indexes of the KCl substitution; the hardness of the potassium lactate substitution was significantly decreasing compared with the control; the optimum conditions were NaCl 55%,KCl 30%, potassium lactate 15%,curing time 72 h.In conclusion,the amount of sodium added in the new formula decreased by 45% and the texture is improved obviously compared with the traditional process.
