Abstract
This study was carried out to investigate the effects of various kinds of commercial salts, including Hanju salt, Deep sea water salt, $Salicornia$ $herbacea$ salt, Guwoon salt, Bamboo salt and salt replacement for the reduction of Na concentration in $kimchi$. The fermentative characteristics of these salts were determined during the fermentation at $10^{\circ}C$. $kimchi$ using a salt replacement and with $Salicornia$ $herbacea$ salt showed slow changes in their pH values. The use of salt replacement showed the lowest level(0.97%) of the retardation of $kimchi$ fermentation. For the preparation of $kimchi$ that used a low Na, chemical and microbial changes were investigated during the fermentation of process, examining preparations with both table salt and a salt replacement(CS-17). The salinity level of $kimchi$ prepared with table salt(control) and the salt replacement (CS-17) were 2.17~2.5% and 1.72~1.99% during fermentation, respectively. The Na contents of $kimchi$ with CS-17(562.5 mg%) showed a lower level than that with table salt(879.0 mg%). The growth of Leuconostoc sp. was highest ($1.5{\times}10^8$ cfu/g) in $kimchi$ with CS-17 at 6 day-fermentation, but the highest level($2.3{\times}10^7$ cfu/g) in $kimchi$ with table salt was at 7dayfermentation. The cells of $Lactobacillus$ sp. in the $kimchi$ prepared with CS-17 and table salt increased to $3.0{\times}10^8$ cfu/g and $6.0{\times}10^7$ cfu/g at 8day-fermentation, respectively. It was concluded that the use of CS-17 could reduce Na levels in $kimchi$ and mitigate over-maturation.
