  • We aimed to develop a new salting method to improve the quality of Dombaegi. The changes in quality characteristics of Dombaegi during salting using different salting methods (dry and brine salting) and salting pressures (vacuum and atmospheric pressure) were investigated. Moisture content was highest in Dombaegi prepared by brine salting under atmospheric pressure. Salt content was greater when salting was conducted under vacuum compared with atmospheric pressure. Water-holding capacity and water activity were higher under vacuum pressure than at atmospheric pressure and after dry salting compared with brine salting. Color change varied greatly when Dombaegi samples salted at atmospheric pressure and under vacuum were compared, and was affected more by dry salting than brine salting. Springiness was higher after salting under vacuum, and in dry conditions. The results showed that dry salting under vacuum provided better quality characteristics compared with other methods. Therefore, salting under vacuum was the optimal salting process.

  • This study was carried out to analyze the physicochemical properties according to salting methods of eggplants exported mainly to Japan. Moisture contents of Chukyang and Shikibu were decreased after 3 days of salting regardless of salting methods. The decrease of moisture content in mixed treatment of rice husk and salt was higher than that of salt treatment after 7 days of salting. Ash contents of Chukyang and Shikibu were increased according to extended salting time regardless of salting methods. The Brix of Chukyang and Shikibu without salting were $4.0^{\circ}brix\;and\;5.0^{\circ}brix$, respectively, and were increased according to extended salting time regardless of kinds and salting methods. pH of Chukyang and Shikibu without salting were 6.04 and 6.00, respectively. Extended the salting time from 0 to 7 days did not result in a pH change. Reducing sugar contents of Chukyang and Shikibu were increased according to extended salting time, the increase of reducing sugar content in mixed treatment of rice husk and salt was higher than that of salt treatment during salting. Soluble protein contents of Chukyang and Shikibu without salting were 1.40 g and 1.85 g, respectively. Extended the salting time from 0 to 7 days resulted in gradual increase in soluble protein content of Chukyang and Shikibu.

  • The effects of salting methods on sensory and microbiological properties of Kakdugi were evaluated during fermentation at 10$\^{C}$ for up to 52 days. Kakdugi samples were prepared by 4 different salting methods at the final salt concentration about 1.5%, which was appropriate for organoleptic quality. The salting methods for radish cubes(2cm size) of Kakdugi included; 1) Treatment S-1: spraying dry salt uniformly onto the radish cubes, at the concentration of about 1.5%(w/w) and cured for 1 hr, 2) Treatment S-5: spraying dry salt uniformly onto the radish cubes, at the concentration of about 1.2%(w/w) and cured for 5 hr, 3) Treatment B-1: brining radish cubes in a 8.5%(w/v) salt solution and cured for 1 hr, 4) Treatment B-5: brining radish cubes in a 4.0%(w/v) salt solution and cured for 5 hr. During the early stage of fermentation, sensory test showed higher scores in the overall acceptability of Kakdugi prepared with salting methods S-1 and S-5 than those with B-1 and B-5. However, the trend of acceptability has been reversed by the treatments B-1 and, more notably, by B-5 at the later stage of fermentation. The counts of lactic acid bacteria increased remarkably and then decreased gradually after the optimum ripening period. The major lactic acid bacteria isolated and identified from Kakdugi were Pediococcus, Streptococcus, Leuconostoc, and Lactobacillus.

  • This study compared quality changes among brined baechu cabbages manufactured by various salting methods and types of salt. Brine, brine and dry salting, and dry salting were used as salting methods. When baechu cabbages were salted by dry salting method, the salinity of brined baechu cabbage increased compared to salting by other methods, even though the quantity of salt used was small. In addition, salinities of leaf and stem were relatively equal among brined baechu cabbages using dry salting method compared to those of other methods. When baechu cabbages were salted using dry method at different salt concentrations (3%, 5%, and 10% of weight of baechu), brined baechu cabbage showed suitable salinity (1.41~1.42%) at 5% salt concentration. Among brined baechu cabbages prepared using dry salting method with different types of salt (purified salt, solar salt, and bamboo salt), bamboo salt produced the highest salinity. Brined baechu cabbages with solar salt and bamboo salt showed significantly lower counts of total aerobic bacteria and higher counts of lactic acid bacteria than others. These results indicate that baechu cabbage can be salted equally, and the amount of salt used can be reduced when baechu cabbage is salted using dry salting method. In addition, using solar salt and bamboo salt can increase the quality of brined baechu cabbage.

  • The effects of salting methods on textural properties of Kakdugi were evaluated during fermentation at 1$0^{\circ}C$ for up to 52 days. Kakdugi samples were prepared by 4 different salting methods at final salt concentration of 1.5%, which is appropriate for organoleptic quality. The salting methods for radish cubes(2 cm size) of Kakdugi were as follows; 1) Treatment S-1: spraying dry salt uniformly on to the radish cubes at 1.5%(w/w) and holding for 1 hr, 2) Treatment S-5: spraying dry salt uniformly on to the radish cubes at 1.2%(w/w) and holding for 5 hr, 3) Treatment B-1: brining radish cubes in a 8.5%(w/v) salt solution for 1 hr, 4) Treatment B-5: brining radish cubes in a 4.0%(w/v) salt solution for 5 hr. The contents of water soluble pectin, total soluble solid and PG activity were increased as the fermentation periods increased. A majority of total dietary fiber(TDF) consisted of soluble dietary fiber(SDF), and the amount of insoluble dietary fiber(IDF) was relatively small in Kakdugi during fermentation. Furthermore, an increase in SDF and a consequent decrease in IDF contents were observed with the fermentation time increased.

  • We investigated the changes of chemical compositions during fermentation of salted anchovy by salting methods for the purpose of establishment of processing condition. Dehydration of anchovy meat occurred remarkably by dry salting compared with that by brine salting and salinity was higher in anchovy by brine salting than by dry salting. Dehydration and salinity were increased in more anchovy fermented at $20^{\circ}C$ than at $5^{\circ}C$. Total nitrogen content was lower in anchovy by brine salting than by dry salting. Amino nitrogen increased remarkably during fermentation of salted anchovy at $20^{\circ}C$, while increased slightly at$5^{\circ}C$. Amino nitrogen showed maximum value on 120 days in dry salting and on 30 days in brine salting at $20^{\circ}C$, respectively. The changes of VBN were similar to the changes of amino nitrogen. The brine salting accelerated hydrolysis of anchovy meat compared with that of dry salting at $20^{\circ}C$, and the hydrolysis were suppressed at $5^{\circ}C$, The POV increased rapidly in dry-salted anchovy than brine-salted anchovy. We suggested that the appropriate processing condition of salted anchovy is to ferment for 5-6 months at $5^{\circ}C$ by addition of $25\%$ salt after pre-salting of raw anchovy.

  • This study was conducted to find the optimum pretreatment method to improve the quality of Pleurotus eryngii pickled with the fermented soybean paste. Blanching(70 , 10min), salting(5%, 20 , 72hr) and drying(50 , 3hr) were used as pretreatment methods. The moisture loss of the mushrooms during pickling was accelerated more by salting and drying. Salinity increase was retarded by salting. Surface and internal browning of the mushrooms were suppressed by blanching. Hardness tended to increase sharply until 20 days of pickling and then slowly decreased. In the sensory evaluation, mushrooms pickled for 40 days were scored as the highest. Blanching was a superior treatment compared to the others in term of color, taste, flavor, texture and overall acceptability.

  • The effects of salting methods on Kakdugi (cubed radish kimchi) fermentation were evaluated. Kakdugi was prepared with various salting methods, salt concentrations, and settling times, and fermented at 10$^{\circ}C$ for up to 52 days. Radish (Raphanus sativus L.) cubes (2 cm size) were salted by using the following methods salt concentration of about 1.5% which was known appropriate for the organoleptic quality of Kakdugi: 1) Treatment S-1: applying dry salt uniformly onto the radish cubes, with a salt concentration of about 1.5% (w/w) and cured for 1 hr, 2) Treatment S-5: applying dry salt uniformly onto the radish cubes, with a salt concentration of about 1.2% (w/w) and cured for 5 hr, 3) Treatment B-1: brining radish cubes in a 8.5% (w/v) salt solution for 1 hr, 4) Treatment B-5: brining radish cubes in a 4.0% (w/v) salt solution for 5 hr. As the fermentation continued, the initial high decrease in pH has been retarded in all the treatments, of which the delaying extent was more significantly noted from B-1 and B-5 than S-1 and S-5. The pH of the Kakdugi which showed a good eating quality dropped to 4.3∼4.8 with the accumulation of total acids. Total vitamin C increased sharply at the palatable period of Kakdugi during the initial fermentation and then decreased gradually following a sigmoidal changing pattern. The reducing sugar levels were also influenced by salting methods and fermentation as sugars are converted into acids. High initial contents of reducing sugars and their subsequent rapid decrease were observed in “S” group than “B” group during fermentation. For nonvolatile organic acids, lactic acid increased consistently throughout the fermentation while malic acid, which was high at the initiation of fermentation, decreased rapidly afterwards at the palatable period of Kakdugi.

  • This study was carried out to develop a standard methods of mechanized salt-inserting salting process for winter cabbage to produce kimchi. Mid or large scaled mechanized kimchi plants were surveyed to select dominant variables of the mechanized salting process. Salt concentration of salting water, salting time and dewatering time were selected as the dominant variables of the salting process. A series of laboratorial experiment was performed with winter cabbage to determine desirable conditions for the variables. A supplementary experiment with cabbages of the other seasons was executed also to compare the determined conditions each other. Finally the determined conditions of the salting process were tested by plant scale experiments with winter cabbage and proved their validity.
