Effect of Partial Replacement of Sodium Chloride on Quality of Ground Pork Patties

돈육식품의 품질에 미치는 Chloride Salts의 대치 효과

The ground pork patties were made to add two level of sodium chloride(2.5%, 3.0%) and replace part(50%) of the sodium chloride(NaCl) with either potassium chloride(KCl), magnesium chloride(MgCl2) or calcium chloride(CaCl2). These samples were analyzed for their chemical composition, VBN value, TBA value, microbial counts, and cooking loss. The ground pork with NaCl 2.5% was more desirable in saltness than the ground pork with NaCl 3.0%. Replacing 50% of the sodium chloride with potassium chloride was more desirable to flavor, color, juiciness, and overall acceptability than replacing 50% of the sodium chloride with either magnesium chloride or calcium chloride. The ground pork with NaCl 2.5% or NaCl 1.25% ＋KCI 1.60% had higher pH value than the ground pork with NaCl 1.25% ＋MgCl2 0.67% or NaCl 1.25% ＋CaCl2 0.79%. The ground pork with the ground pork with NaCl 2.5% had lower VBN value than the ground pork with either NaCl 1.25%＋KCI 1.60%, NaCl 1.25% ＋ MgCl2 0.67%, or NaCl 1.25% ＋CaCl2 0.79%. The ground pork with NaCl 1.25% ＋ CaCl2 0.67% had higher increase in total colony count than the ground pork with NaCl 2.5% or NaCl 1.25% ＋ CaCl2 0.79%. Cooking loss of ground pork with NaCl 2.5% was lowest and cooking loss of ground pork with NaCl 1.25% ＋ KCl 1.60% was highest. Potassium chloride would not be a substitute for sodium chloride in cooking loss and total colony count but potassium chloride more closely approximated the sensory properties of sodium chloride than either magnesium chloride or calcium chloride.
