This study was conducted to optimize the level of sugar added (20 (control), 15, 10, 5%) during the preparation of soy sauce-salted mushrooms (Pleurotus eryngii) jangachi without affecting the degree of preference. The salinity and sugar content during storage of soy sauce-salted mushrooms (Pleurotus eryngii) jangachi decreased significantly as the level of sugar added decreased. The moisture content was found to increase as the level of sugar added decreased. Additionally, the pH increased, while hardness decreased as the level of sugar added decreased during 3 weeks of storage. The L value (lightness) was not different from that of the control group until the addition of 10% sugar, while the a value (redness) and b value (yellowness) increased. The antioxidant activity of vitamin C content and DPPH radical scavenging activity increased as sugar content decreased. Upon sensory evaluation of mushrooms (Pleurotus eryngii) jangachi, the highest value in appearance was observed for the 5 and 15% treatments, while 5% had the highest flavor value, 15 and 10% had the highest taste values, 10 and 15% had the highest texture values, the control and 5% had the greatest clarification values, and the 15 and 10% groups had the greatest overall acceptance. These results suggest that a sugar level of 15% can be used without significantly affecting the overall acceptance.
This study aimed to determine the physicochemical properties (proximate composition, color, pH, salinity, water holding capacity (WHC), curing yield, and shear force) and sensory properties (electric nose and sensory evaluation) of Bulgogi sauce with added crust derived from dry-aged beef loin. Increasing the amount of crust in the Bulgogi sauce tended to increase the protein content, fat content, and pH. Uncooked Bulgogi also tended to have elevated fat content, ash content, pH, and shear force. Increasing the crust content tended to decrease the water content, lightness, redness, and yellowness of Bulgogi sauce. The yellowness of uncooked Bulgogi with 6%-12% crust in sauce was significantly lower than that of the control (no crust) and the sample with 3% crust in sauce (p<0.05). The redness of the cooked control Bulgogi was significantly lower than that of the samples with crust in sauce (p<0.05). The WHC of uncooked Bulgogi with 6%-12% crust in sauce was significantly higher than that of the control and the sample with 3% crust in sauce (p<0.05). The flavor, texture, and overall acceptability of the Bulgogi with 9% crust in sauce were significantly higher than those of the control (p<0.05). These findings showed that the crust did not degrade the physicochemical properties of Bulgogi sauce and meat. The sensory characteristics of Bulgogi marinated with 9% crust in sauce were rated the best as persensory evaluation. Therefore, crust is a suitable flavor enhancer for Bulgogi sauce, and a 9% addition amount is optimal in terms of quality.
Physicochemical properties and sensory evaluation of Satsuma mandarin produced in Cheju were investigated . Fruit index(width/Length), soluble solids and acid content of Citrus unshiu marc. var. miyagawa(miyagawa) and C. unshiu marc. var.(okitsu) harvested at 1st December were 1.16 and 1.23, 12.12 and 12.01, 0.97 and 1.09, respectively. and the fruit of miyagawa was showed somewhat round in shape, compared to ikitsu. the taste of miyagawa seemed to be better than okitsu. However, compared to miyagawa, peel thickness was thinner, flesh ratio was higher, and firmness was higher as 0.502kg-force in kitsu. Nevertheless there were some differences among panelist groups in sensory evaluation , middle size of citrus fruits were favorable to most panelists, but except very small or very large size of fruits, there were not so much differences in okitsu. The panelists referred to somewhat flat-shaped fruits from that sensory evaluation score was increased to 1.3 in fruit index. nevertheless there were not so much differences in full-colored fruits, the citrus peel color of reddish yellow was more favorable than greenish or pale yellow color. the score was increased more linearly according to citrusfruit produced in optimum ciltivation area, and was prefered to thinner in peel thickness , Correlation between soluble solids, acid content , Brix/acid ratio and flesh ratio with sensory evaluation score were not showed significantly, it was different to with citrus juice. This data obtained in this experiments are supposed to be applied to the quality evaluation of Satsuma mandarin produced in Cheju .

This study was conducted for the evaluation of air-pollution using pear plant. Twenty-three sites around the Ulsan Industrial Complex Area were selected for the study. The water soluble sulfur content, photosynthetic rate and the visible injured index of pear leaves were evaluated and the results are summarized as follows: 1. Water-soluble sulfur content of pear leaves at survey sites was shown to be an average of 0.201%. The content of their leaves at polluted sites ranged from 0.220 to 0.496%. Water-soluble sulfur content of the pear leaves decreased as the distance became far from the Industrial Complex. 2. The photosynthetic rate of pear leaves decreased with an accumulation of water-soluble sulfur content. However it increased as the distance became greater within the five-kilometer radius of the pollutant. 3. More than 60% of injured rate was shown in pear plant within the five-kilometer radius of the pollutant in 1993. There were high correlations between the visible injured index items. Compared with 1988, the most severely injured sites in 1988 were Yochon-dong and Yaum-dong. But in 1993, they moved to the Yongcham-dong and Bugok-dong area. 4. Water-soluble sulfur content of pear leaves was correlated with the photosynthetic rate of pear leaves. The same tendency was shown between water-soluble sulfur and total injured index. This method using pear plant will be applied to the evaluation of air pollution.

This study was carried out to investigate the quality characteristics and antioxidant activities of bread containing mistletoe (Viscum album var.) powder (at ratios of 0, 3, 5, 7, and 10% of total flour quantity). As mistletoe powder (MP) content increased, the pH levels of dough and bread and lightness decreased, whereas total titratable acidity increased. The fermentation power of the dough expansion by fermentation decreased with an increase in MP content added. Although bread weight decreased, there were no significant differences in baking loss as MP content increased. Volume and specific volume significantly decreased as MP content increased. Moisture content was highest at a substitution level of 10% and increased with increasing MP content. Lightness of crumbs significantly decreased with increasing MP content, whereas redness and yellowness showed the reverse effect. As MP content increased, changes in hardness, gumminess, and brittleness were all significant. In the sensory evaluation, color, flavor, softness, and overall acceptability were highest at MP 3% and were lowest at MP 10%. Total polyphenol contents and DPPH radical scavenging activity of bread significantly increased with increasing MP content. In conclusion, addition of MP 3% showed the best performance in terms of the nutritional and functional aspects of the bread.
