The purpose of this study was to develop a supplemental healthy food that can help prevent high blood pressure-related diseases caused due to the excessive consumption of sodium in salt. This was achieved by using ion-displacement techniques to produce mineral salt with lower sodium content by using fermented brown rice by-products rich in minerals. Mineral salt containing 2019.2 mg/100 g of potassium, 678.5 mg/100 g of magnesium, 48.7 mg/100 g of calcium, and 19.5 mg/100 g of sodium was obtained by fermenting brown rice by-products to create a culture medium for the mineral salt. Mineral salt containing 1769.7 mg/100 g of potassium, 573.6 mg/100 g of magnesium, 35.3 mg/100 g of calcium, and 19.5 mg/100 g of sodium was obtained by filtering and refining the by-product extract of fermented brown rice. The results showed that when the stream velocity of the instrument used for electrolysis was 200 mL/min and the current and the concentration of the reactive liquid in the purified water chamber were higher, the effect of electrolysis was greater. Ion hot water extraction of the fermented brown rice by-products improved by up to 95% and was collected as purified water within 90 min of the reaction time. Chloride ions with pH 7.4 were produced by mixing sodium hydroxide in a purified saline water chamber with electro-analyzed water. The salt produced in this study contained low sodium, 5.7~30%, as compared to 40% sodium content of the normal salt.

This study was carried out for the functional investigation of the Ulmus pumila L. extracts for use in functional-food processing. Extracts of Ulmus pumila L. were obtained using distilled water and 70% ethanol, and the extracts were tested for their electron-donating ability, SOD-like activity, nitrate-scavenging ability, and anticancer (MDA and A 549 cells) activity. The extraction yields of the water and ethanol extracts were 12.7 and 12.0%, respectively; the polyphenol contents were 623.5 ± 2.4 and 710.5 ± 2.1 mg/100 g; the electron-donating ability was high in proportion with the density; and the water extract was higher than the ethanol extract (76 and 64%, respectively) at 1,000 ppm. In all the 1,000 ppm densities, the SOD-like activity of the water extract was far higher than thatof the ethanol ex tract (53 and 38%, respectively), and the nitrite- scavenging ability of the ethanol extract was higher than that of the water extract (47 and 43%, respectively). As for the anticancer ability at 1,000 ppm, it was 62% in the water extract and 42% in the ethanol extract in the MDA cell, and 60% in the water extract and 45% in the ethanol extract in the A 549 cell. Thus, the proliferation inhibition ability of the water extract against cancer cells was found to be far higher than that of the ethanol extract (60 and 45%, respectively).

In this study, 0, 20, 40, 60, 80, and 100% Ulmus pumila L. nonglutinous and glutinous sikhe were added to Ulmus pumila L. extracts for 15 days at 4℃, and for seven days at 25℃, to examine the extracts' storage properties and sensory characteristics. The results are as follows: (1) On the changes of pH and acidity during storage of Ulmus pumila L. nonglutinous and glutinous sikhe, both of them showed lower pH values with lower additive Ulmus pumila L. extract contents. The pH value continuously decreased with a longer storage period, and the acidity was higher with a lower concentration of Ulmus pumila L. extract. (2) The total microbial cell count during storage of Ulmus pumila L. nonglutinous and glutinous sikhe at 4℃ was 4.6-5.0 log CFU/g at 0 day. The sikhe to which Ulmus pumila L. extract was not added increased to 8.8-9.0 log CFU/g on the seventh storage day, while the sikhye to which 80 and 100% Ulmus pumila L. extracts were added were 7.8 and 6.9 logCFU/g, respectively. Thus, the total cell count was lower with a higher additive content of Ulmus pumila L. extract. The total cell count of the sikhe to which 0-60% Ulmus pumila L. extracts reached the maximum value on the seventh storage day and did not show any change thereafter. The total cell count of the sikhe to which 80 and 100% Ulmus pumila L. extracts were added, however, reached the maximum value on the 10th to 13th storage days, thus showing that the storage period was increased by Ulmus pumila L. At 25℃, the total cell count was 4.6-5.0 log CFU/g on 0 day and continuously increased during the storage period. It had increased to 8.9-9.5 log CFU/g on the seventh storage day, and no differences were shown according to the additive content of Ulmus pumila L. extract. (3) On the sensory characteristics of Ulmus pumila L. nonglutinous and glutinous sikhe, the Ulmus pumila L. nonglutinous sikhe to which 20% Ulmus pumila L. extract was added showed the highest overall-acceptability value (4.23±0.95), whereas the Ulmus pumila L. glutinous sikhe to which 40% Ulmus pumila L. extract was added showed the highest overall-acceptability value (3.95±0.95). The sikhe to which 20 and 40% Ulmus pumila L. extracts were added showed significantly high taste, flavor, sweetness, and overall-preference values (p<0.05).

Water extract of green tea(GTW) and 70% ethanol extract of green tea(GTE) were prepared for the test of antibacterial activity. The sensitivity of Staphylococcus aureus and Salmonella typhimurium to the green tea extracts in various pH of culture broth was tested. Tryptic soy broth(TSB) containing 0∼2%(w/v) of green tea extracts was adjusted to pH 5.0∼7.0 and inoculated with 105/∼106/ cells/ml of each bacteria. The plate counting method and clear zone test were used to determine inhibitory effect of green tea extracts. Green tea extracts completely inhibited the growth of S. aureus at 0.5% level and bactercidal at 0.5∼1.0% level of GTW and GTE at pH 5.0∼7.0. Green tea extracts were bactercidal to S. typhimurium at 1.5∼2.0% level of GTW and 1.0∼2.0% level of GTE at pH 7.0. Sal. typhimurium was more resistant than S. aureus. in same concentration of green tea extracts at same pH. The resistance of S. aureus and Sal. typhimurium was increased with decreasing pH of culture broth. The morphology of S. aureus cells treated with green tea extracts showed damage of cell wall and cytoplasmic membrane. Severely damaged cells of S. aureus lost electron dense material and cytoplasm. Green tea extracts stimulated autolysis and cell death of S. aureus. This result suggests that green tea extracts can be used as an effective natural antibacterial agent in food.
