In this study, the anti-oxidant and anti-elastase activities of four abalone viscera extracts were investigated to screen the most promising extract. This extract was further studied in terms of its anti-skin-aging properties. In the DPPH-scavenging assay, the Tris-HCl extract showed a 58.60±0.88% radical-scavenging activity, which was followed closely by the ethanol extract that had a 55.40±0.62% scavenging activity. In the anti-elastase assay, however, the ethanol extract showed the significantly highest elastase inhibition activity. Furthermore, none of the extracts had a harmful effect on the human dermal fibroblast, as revealed in the MTT assay. In the cell study, the effect of the ethanol extract at various concentrations on the human dermal fibroblast was investigated. At the 10 μg/mL concentration, the ethanol extract boosted the pro-collagen type I synthesis to 705.30±3.06 ng/mL and reduced the MMP-1 to 54.30±0.80 ng/mL, which was considered the optimum concentration. This is the first study that focused on the anti-oxidant and anti-skin-aging effects of abalone viscera extract. Its results may provide fundamental data for further study.

Enzymatic action and microbial growth degrade the quality of fresh-cut lettuce. Browning, a bad smell, and softening during storage are the major forms of quality deterioration. Health-oriented consumers tend to avoid foods treated with chemicals to maintain their freshness. This study was conducted to evaluate the change in the quality of fresh-cut lettuce with combined low-temperature blanching (LB) and ultrasonication (US). The optimum condition was selected using the response surface methodology (RSM), through a regression analysis with the following independent variables; the ultrasonication time (X1), blanching temperature (X2), blanching time (X3), and dependent variable; ΔE value (y). It was found that the condition with the lowest ΔE value occurred with combined 90s US and 45℃ 90s LB (US+LB). The combined treatment group (US+LB) was stored at 10℃ for 9 days with the control group and each single-treatment group, with low-temperature blanching and ultrasonication. Overall, the US+LB group had a significantly high L* value, which indicates significantly low a*, b*, ΔE, browning index, PPO, and POD activity values, and a low total bacteria count (p < 0.05). The US+LB group also had the highest sensory score (except for aroma and texture; p > 0.05).

This study was conducted to investigate the pH, soluble solid contents, color difference, mineral contents, free sugar contents, and sensory quality of infrared- and cold-air-dried peaches. The pH, soluble solid contents, and free sugar contents of the infrared-dried peaches were higher than those of the cold-air-dried peaches. In the Hunter’s color value, the L and ΔE values of the infrared-dried peaches were higher than those of the cold-air-dried peaches; but the a and b values of the cold-air-dried peaches were higher than those of the infrared-dried peaches. The major organic acids of the dried peaches were citric acid, malic acid, and oxalic acid. The minerals with the highest to lowest contents, in that order, were K, Mg, Ca, Na, Fe, Zn, Cu, and Al. The mineral contents of the cold-air-dried peaches were higher than those of the infrared-dried peaches. The appearance and taste of the infrared-dried peaches were better than those of the cold-air-dried peaches. These results indicate that infrared drying is the effective drying method for the production of high-quality dried peaches.

The quality characteristics of Acanthopanax and Cedrela shoots during their preservation were investigated according to the salting conditions to improve the use of the shoots. The results were as follows: The pH of added ionization mineral during the storage did not change. The salinity of the salt-stored Acanthopanax and Cedrela tended to insignificantly change as their storage temperature changed and increase during the addition of the ionization mineral. In terms of the color values, the b value of the added non-ionization mineral tended to increase and that of the added ionization mineral tended to gradually decrease. The texture of Acanthopanax and Cedrela shoots to which an ionization mineral was added tended to decrease gradually during their storage, and was highest when 50 ppm of the ionization mineral was added. The total chlorophyll contents tended to decrease during the salt storage, did not change significantly with the change in the added ionization mineral, and decreased at the storage temperature of 10℃. Therefore, it can be concluded that quality of Acanthopanax and Cedrela shoots can be maintained when they are stored in ionization mineral addition.

In this research, to modernize traditional food and to make functional bokryung-byung, bokryung-byungwas made with Poriacocos Wolf powder added. During its storage, its moisture content ranged from 42.89 to 44.85%. The control group had the highes tmoisture content (44.85%), and it was reduced significantly as the Poriacocos Wolf powder in creased. The longer the storage period was, the lower the pH and the higher the acidity was. The total bacterial count increased from 2.70 to 3.00 Log CFU/g right after the manufacture and increased rapidly on the fourth day of the storage with more than 7.00 Log CFU/g. There was no difference between the control group and the bokryung-byung, though. The Hunter’s color value after the manufacture, with the increase in the added Poriacocos Wolf powder, showed a significantly reduced brightness, but significantly increased redness and yellowness. Their chromaticity did not change, how ever, during their storageat a temperature of 20 °C. The hardness, solidity, gumminess, and cohesiveness of the bokryung-byung increased, unlike in the control group, and its brittleness increased. In terms of the overall preference, the preference for the control group was high, but was higher when 5 % Poria cocos Wolf powder was added during the manufacture of the bokryung-byung. As a result of these correlations, it is believed that elastic and chewy dduks are preferred and bokryung-byungs could be developed as functional dduks.

In this study, we investigated quality and fermentation characteristics in baechu kimchi containing 0(control), 5(GK5), 10(GK10), 15(GK15) and 20(GK20)% of shred garlic. Analysis was performed during fermentation at 4℃ for 42 days, every 7 days. The result showed significant changes in color value between control group and garlic added groups. Hunter’s color L value was increased during fermentation whereas a and b value were decreased. Hardness of kimchi was higher in 15% and 20% garlic added groups than other groups. The pH decreased significantly during fermentation, while titratable acidity was showed reverse tendency during fermentation period. The reducing sugar content was decreased in all groups during fermentation period, which higher in GK10 and GK15 group than the others. But its remaining ratio was 19.7∼22.3% and not showed significant difference in experimental groups at 42 days fermentation. The number of lactic acid bacteria was dramatically increased up to 6.13∼7.60 log CFU/g at 7∼14 days fermentation. The garlic was inhibited significantly the growth of lactic acid bacteria, but this was not showed significant difference between garlic added groups and control group, after 28 days fermentation. As a results, we suggest that addition of garlic increase the quality characteristics and storage properties of Kimchi, and not hinder quality of kimchi at addition level of 20% than salted baechu.

To evaluate the effect of aging on solar salts produced in Korea, the chemical compositions of the solar salts, including their heavy metal contents, were analyzed after they were aged for one-year (OA) and for three years (TA). The average contents of the components were: sodium chloride; 81.4% (OA) and 90.9% (TA), chloride; 57.7% (OA) and 65.0% (TA), moisture content; 4.7% (TA) and 12.0% (OA), insoluble solids; 0.03% (OA) and 0.04% (TA), and SO4 ions; and 0.57% (TA) and 0.85% (OA). No significant difference was found, however, in the heavy metal contents. Heavy metals such as As, Pb, and Hg were detected with values far below the maximum permissible limit, and Cd was not detected in the salts. The TA solar salts showed higher values of sodium chloride, chloride, and insoluble solids than the OA solar salts, but the TA solar salts had lower moisture and SO4 values. These results clearly indicate that the levels of heavy metals in the OA and TA solar salts that are produced in Korea are safe.
