In this study, the quality characteristics and storage properties of gat kimchi added with oyster shell powder and Salicornia herbacea powder were investigated during a storage time of 80 days at $5^{\circ}C$. After storage for 80 days, the average calcium contents were significantly higher in the kimchi containing the oyster shell powder and Salicornia herbacea powder than the control. In addition, the average hardness value was significantly higher in the OS4 group(oyster shell powder at 4% and Salicornia herbacea powder at 2%) than the control group, as well as the OS10 group(oyster shell powder at 10% and Salicornia herbacea powder at 2%) during storage for 80 days. The hunter b value of the OS4 group was significantly lower than the control group. During fermentation, gat kimchi containing the oyster shell powder and Salicornia herbacea powder had a higher pH and a lower acidity value than the control group. In terms of sensory evaluation, there were no significant differences between the control and calcium-added kimchi during fermentation. After 40 days of storage, the OS4 group showed a lower total viable count, as well as lower lactic acid bacteria, yeast and E. coli, as compared with the control and OS10 groups. Based on the microbial load, the gat kimchi containing the oyster shell powder showed limitations in terms of shelf life.

This study was conducted to investigate the effects of saltwort on the quality characteristics of tofu. In addition, we examined the potential for commercialization of tofu containing saltwort. For this study, saltwort was added to tofu at 0%, 4%, 8%, 12%, 16% and 20% and quality and sensory tests were administered. Analyzing the mineral contents of saltwort juice, K was present in the greatest amount, followed by Mg, P, Ca, and F (in decreasing order). There were significant differences in yield rates and turbidity between the groups. Acidity was highest in the control group, and acidity and volume of tofu tended to decrease with an increase in saltwort powder. L value and a value decreased as the content of slaltwort powder increased, but b value increased with increasing saltwort powder concentration. Hardness, chewiness, and gumminess were rated higher in the control and the 4% supplement groups than the others groups. In the sensory evaluation, cross section and soybean flavor were the highest in the 4% saltwort supplement group, and the presence of an "off-flavor" increased with the content of saltwort powder. The saltiness score was highest in the 20% supplement group. The 4% and 8% supplement groups were favored in the "feel after swallowing" assessment. Softness was the lowest in the 20% supplement group, and the 4% supplement group had the highest overall acceptability. As demonstrated by these results, the addition of saltwort positively affected the overall sensory evaluation of tofu and supplementation with saltwort at 4% and 8% might be considered the most appropriate choices. In conclusion, saltwort tofu expected to increase the functionality of new products, particularly with respect to product variety and health improvement.

This study was performed in an effort to create a functional and stable yogurt product containing slander glasswort extract. The extract was added to milk at concentrations of 0.25, 0.5, and 1.0% (w/v), which was then fermented with lactic acid bacteria (Lactobacillus bulgaricus and Streptococcus thermophilus) at $42^{\circ}C$ for 6 hr. During a period of 15 days of storage, the quality characteristics of the yogurt samples were evaluated in terms of acid production (pH and titratable acidity), levels of lactic acid bacteria, color values, viscosity, and sensory characteristics. There were no significant differences in pH during the storage period; however, the control yogurt presented the highest pH value. The 1.0% slander glasswort yogurt had the highest titratable acidity; but again, there were no significant differences among the yogurts. The 1.0% slander glasswort yogurt also had the highest level of lactic acid bacteria, and both the control and slander glasswort-containing yogurts had increasing levels of lactic acid bacteria over the storage period. The 1.0% slander glasswort yogurt had the lowest L-value and highest a- and b-values. And the slander glasswort yogurts presented lower viscosity values than the control. In sensory evaluations, the 0.25% slander glasswort yogurt scored higher than the other groups for color, flavor, viscosity, sweetness, sourness, and overall palatability. The final sensory results indicated that the 0.25% slander glasswort yogurt was superior.

To investigate Oiji (traditional Korean cucumber pickles) with reduced sodium content based on the use of saline foods as a salt substitute, Oiji was prepared using glasswort powder (Salicornia herbacea L.), and its physicochemical properties and sensory evaluation were examined. The moisture content of Oiji was shown to be higher in those to which glasswort powder had been added compared to the control without addition of glasswort powder, and Oiji with 40% glasswort powder substitute showed the highest pH and lowest acidity, resulting in slow progression of fermentation. The salinity of Oiji among those containing glasswort powder substitute was significantly higher with increasing level of glasswort powder. The sodium content of Oiji was significantly reduced as addition of glasswort powder increased. The L value of Oiji decreased with increased addition of glasswort powder, whereas the a value was highest in the control. The hardness of Oiji was higher in the control than in Oiji containing glasswort powder. Taste acceptance was highest for Oiji with 20% glasswort powder substitute, whereas acceptance of appearance was higher for Oiji with 10% glasswort powder substitute. Flavor and texture acceptance was higher for the control. In the attribute difference test, significant differences were found in brownness, off-flavor, salty taste, and sourness. Based on the findings, 10-20% substitution of salt with glasswort powder did not significantly lower overall acceptance compared to the control while salinity of Oiji was maintained. Therefore, the potential production of low-sodium Oiji has been verified.

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.

In this study, the antioxidative effects of Sueada asparagoides and Salicornia herbacea extracts were investigated. The free radical(1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity($FSC_{50}$) of extract/fractions of Sueada asparagoides was in the order: 100 % ethanol extract(329.33 ${\mu}g/mL$) < 50 % ethanol extract(40.73) < ethylacetate fraction(13.87) < deglycosylated aglycone fraction (7.80). In case of Salicornia herbacea, the free radical scavenging activities of ethylacetate fraction and aglycone fraction were 13.87 and 7.80 ${\mu}g/mL$, respectively. Reactive oxygen species(ROS) scavenging activities($OSC_{50}$) of Sueada asparagoides and Solicornia herbacea extracts on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system were investigated using the luminol-dependent chemiluminescence assay. The order of ROS scavenging activity of Sueada asparagoides extracts was 50 % ethanol extract($OSC_{50}$, $0.99{\mu}g/mL$) < ethylacetate fraction (0.05) < aglycone fraction (0.03). Aglycone fraction showed the most prominent scavenging activity. In case of Salicornia herbacea, the ROS scavenging activities of ethylacetate fraction and aglycone fraction were 0.10 and 0.20 ${\mu}g/mL$, respectively. The protective effects of extract/fractions of Sueada asparagoides and Salicornia herbacea on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The ethanol extract(100%) of Sueada asparagoides diminished photohemolysis in a concentration dependent manner($1{\sim}100{\mu}g/mL$). Particularly deglycosylated aglycone fraction exhibited the most prominent celluar protective effect($\tau_{50}$, 310 min at 50 ${\mu}g/mL$). In case of Salicornia herbacea, ethylacetate fraction exhibited more potent protective effect. These results indicate that extract/fractions of Sueada asparagoides can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging $^1O_2$ and other ROS, and protect cellular membranes against ROS.
