Characteristics of Low-Salt Kimchi Prepared with Salt Replacement during Fermentation

Abstract

Eleven salt replacements composed of NaCl, KCl, , lysine or glutamic acid were prepared and used for the preparation of low salt Kimchi instead of NaCl alone. Some chemical and microbiological characteristics of the low-salt Kimchi with 2.5% salt replacement were determined during the fermentation at . The pH decrease and acidity increase of low-salt Kimchi were slower than those of control Kimchi with NaCl alone. The total number of microorganism in SR-8 Kimchi added L-lysine was lower than that of control Kimchi until 5 days of fermentation. However, there was no difference in the numer of lactic bacteria between low-salt Kimchi and control Kimchi. The growth of yeasts was found to be slow in low-salt Kimchi with SR-8. The low-salt Kimchi with SR-3 showed the hardest texture among the prepared Kimchi. The overall acceptabilities of low-salt Kimchi prepared with SR-1, SR-3 composed of NaCl, KCl, , and SR-10 added 0.2% glutamic acid to the elements were similar to the control Kimchi.
