  • 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.

  • 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 undertaken to investigate changes m curve angle of Chinese cabbage blade during salting at various concentration(10, 15, 20, 25%) of salt to evaluated salting degree by curve angle during salting at 20$^{\circ}C$. Salt concentration of brine, the amount of water elution, salt penetration of the tissue(salt concentration of Chinese cabbage), weight loss and texture were investigated. Correlation relation between the above factors and curve angle were determined. The curve angles by method of holding the edge of the Chinese cabbage blade was measured. The curve angles of the mesophyll were proportional to salting time and salt concentration, but slope of line equation showed higher than that of mid-rib. The ideal method of salting evaluation by curve angle was MCA-MRC (the measuring curve angle of mid-rib C) at each concentration of salt. The results of curve angle when reached 3% salt of Chinese cabbage tissue calculated by MCA-MRC at 10, 15, 20 and 25% salting were 57$^{\circ}$, 43$^{\circ}$, 36$^{\circ}$, and 33$^{\circ}$, respectively. And salting times calculated by the same conditions were 19, 12.5, 9.1 and 4.4hours, respectively.

  • This study was conducted to investigate the effect of different salting conditions, short-time salting(SS) and long-time salting(LS), on the fermentation and quality of dandelion kimchi. The desirable salt concentration of brine and salting time evaluated by salting degree were 16 hrs at 5% brine, 8 hrs at 10% brine and 4 hrs at 15% brine, respectively. Among them, the best quality of salted dandelion was salting of 10% brine for 8 hrs. But the bitter taste in salted dandelion treated by SS was remained. The proper condition to salt and remove the bitter taste in salted dandelion together was salting by LS, which was salted for 4 days in 100% brine changed once a day. pH of the dandelion kimchi salted for 8 hrs in 10% brine during fermentation at $10{\times}$ was lower than that of LS kimchi, but acidity, total microbe, number of lactic acid bacteria, content of reducing sugar and vitamin C were higher than those of LS kimchi. The optimum- fermentation periods of SS(salted for 8 hrs in 10% brine) and LS kimchi evaluated by sensory test were 40th and 50th day, respectively.

  • Salting conditions on organoleptic properties and rheology of Chinese cabbage were optimized and monitored by four-dimensional response surface methodology. Experimental conditions were decided in the ranges of salt concentration 8∼12%, salting time 5∼25 hr and salting temperature 5∼15$^{\circ}C$. The salted Chinese cabbage with experiment design was measured on organoleptic and physical properties. The organoleptic form of the salted Chinese cabbage showed maximum score in 11.28% of salt concentration, 9.75 hr of salting time and 12.81$^{\circ}C$ of salting temperature. The organoleptic taste was maximized in 11.19% of salt concentration, 11.38 hr of salting time and 13.58$^{\circ}C$ of salting temperature. The organoleptic mouth-feel was maximized in 11.24% of salt concentration, 11.71 hr of salting time and 13.57$^{\circ}C$ of salting temperature. The organoleptic palatability was maximized in 11.52% of salt concentration, 12.86 hr of salting time and 13.07$^{\circ}C$ of salting temperature. In rheological properties of salted Chinese cabbage, hardness and chewiness decreased with the increase of salt concentration.

  • This study was performed to find the desirable conditions for processing salted hard-boiled egg without cracking egg shell in NaCl solution under pressure. Among the many factors affecting saltiness of the shell egg, concentration of NaCl solution(0~40%), different salting time(0~45h) and salting pressure (0~4.5kg/$\textrm{cm}^2$) were employed to identify the permeability of NaCl into shell egg at ambient temperature. The saltiness of the shell egg was proportionally risen as concentration of NaCl solution, salting time and pressure increased. The most desirable saltiness was observed at the 0.70~1.00% of NaCl in albumen and 0.40~0.45% in yolk, Besides the saltiness, sensory evaluation of the shell egg were carried out to evaluate the quality of the salted shell egg. The effect of various concentration of NaCl solution, salting time and pressure on sensory scores of hard-boiled salted eggs showed that 20~40% of NaCl solution, 12~20 h of salting time, 3~4.5 kg/$\textrm{cm}^2$ of salting pressure were proper conditions for processing the product. These results indicate that the desirable condition to get salted hard-boiled shell egg were ; 30% of NaCl solution, 16h of salting time and 4.0kg/$\textrm{cm}^2$ of salting pressure.

  • The aim of this study was to develop a new salting condition that included added maltodextrin (MD) and grape seed extract (GSE) to ensure the microbiological safety and quality of salted shredded Korean cabbage. Response surface methodology (RSM) was used to analyze the effects of four independent variables (NaCl concentration, salting duration, MD concentration, and GSE concentration). The following response variables were evaluated: reduction in total aerobic bacteria, yeast, and mold counts; weight loss and salt content; and taste, texture, and overall acceptability of salted shredded Korean cabbage. The optimal salting conditions include a combination of 10.09~10.32% NaCl, 9.45~10.00% MD, and 234~300 ppm GSE in a ternary salting solution and a salting duration of 5.68~5.94 hr. This optimal combination reduced total aerobic bacterial and yeast/molds counts by 3.33 and 1.45 log CFU/g, respectively, while maintaining high sensory scores for taste, texture, and overall acceptability of the salted shredded Korean cabbage. In addition, the optimal conditions yielded more acceptable weight loss and salt content characteristics. The results suggest that use of the optimized combination of salting conditions can improve the microbiological safety and quality of salted shredded Korean cabbage used for commercial kimchi production.

  • To investigate the optimal salting conditions, the physicochemical properties of Dolsan leaf mustard were compared under various salting times and using various washing methods and storage temperatures at 10% saline. On the other hand, the cell number of lactic-acid bacteria in Dolsan leaf mustard salted under the optimal conditions was also examined during the 50-day storage. The results of the sensory evaluation of the crispness value of the Dolsan leaf mustard treated with stepwise washing after 8h salting showed the optimal conditions for long-term preservation. The pH of the salted Dolsan leaf mustard decreased with the increase in the lactic-acid bacteria during the storage at $4^{\circ}C$. The cutting energy slowly increased during the storage, but the cutting energy of the salted Dolsan leaf mustard treated with stepwise washing remained at the initial values. The color of the salted Dolsan leaf mustard did not change during 40-day storage, but the mustard turned brown after 50-day storage, for which reason it could not be made into Dolsan leaf mustard kimchi. These results could be recommended as the optimal salting conditions and storage time of salted Dolsan leaf mustard for making kimchi.

  • 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.

  • We investigated the quality characteristics of Dombaegi after drying, with respect to salt concentration (1%, 2%, 3% all w/v) and salting temperature ($4^{\circ}C$, $18^{\circ}C$), to establish optimum salting conditions. Changes in moisture and salt content, water holding capacity, water activity, color, and textual properties of salted Dombaegi were measured. The moisture content was highest in Dombaegi prepared with 3% (w/v) salt at 4C. The salt content of Dombaegi rose as salt concentration and temperature increased. The water holding capacity was greatest after salting with 3% (w/v) salt at $4^{\circ}C$. Color and texture were superior after preparation at higher salt concentrations and lower salting temperatures. Thus, the quality of Dombaegi was optimal when dry salting was performed at the highest salt concentration (3%, w/v) and the lower salting temperature ($4^{\circ}C$).
