  • The quality characteristics of sugar-reduced green tea cookies were tested, and there was no significant differences in density, spreadability, loss rate, and pH in all experimental groups (p<0.05). The sugar content of the sample with 100% sugar replaced was 0.96°Brix, which was significantly higher than the 0.80 °Brix of the control (p<0.05). The sample with 75% sugar substituted was 0.76°Brix, which was similar to that of the control (p>0.05). The calories per 100 g of cookies were reduced from 482 to 433 kcal in the sample groups, where the sugar content was reduced from 0 to 100%. Carbohydrates also decreased with decreasing sugar content. The protein was 5g in the sugar sample group reduced by 0-25%, and 6 g in the sugar sample group reduced by more than 50%. Dietary fiber was three times higher in the sugar sample group reduced by 75% than the control, and four times higher in the sugar sample group reduced by 100% than the control. No significant differences in the sweet sensory intensities were observed between the control and the 75% reduced sugar sample group (p>0.05). The brightness, savory, sweet, and aftertastes were similar in all experimental groups (p>0.05). Overall, high value-added green tea cookies with a more than 75% reduction in sugar were successfully developed with added functions of immunity, anti-cancer, antioxidant functions, preventing constipation and obesity, without deteriorating the sensory and physicochemical qualities tested.

  • This study investigated the possibility of reducing sodium and sugar intake in the Bulgogi bowl and yogurt, respectively, by utilizing food and non-food factors. Sodium and sugar replacers were the target food factors, and eating environment was the target non-food factor. The sodium content of Bulgogi bowls was reduced by 40%, and a flavor enhancer was applied to compensate for the reduced saltiness. Low calorie sweeteners, such as sucralose and stevia, were used to lower the sugar content of yogurt by 30%. Consumers were asked to evaluate the samples in one of the three eating environments: private booth evaluation, BOOTH; watching video clips during evaluation, VIDEO; conversation with friends during evaluation, FRIEND. The results showed that applying sodium or sugar replacers were effective in lowering sodium or sugar intake, respectively, without compromising the acceptance level of samples. Significant influences of the eating environment were observed on liking and perception of samples, but the influence patterns were not consistent between Bulgogi bowl and yogurt.

  • Various bacterial strains were isolated from water in a paddy field, and their seaweed degrading activities were investigated. As the result, 16 strains were obtained from the microflora sample. They were incubated in a liquid medium of sea tangle powder for 3 weeks. Ratios of reduced sugar to total sugar of the liquid medium were measured once a week during the incubation period. Ratio of reduced sugar to total sugar of 30A412 strain was highest. Accordingly, 30A412 strain was incubated in three different liquid media of sodium alginate, sea tangle powder, and sea mustard powder for 3 or 4 weeks. The ratios of reduced sugar to total sugar and cell growth were measured once a week during the incubation period. Ratios of reduced sugar to total sugar and cell growth were increased with the incubation period. Cell growth and degrading ratio were highest in the liquid medium with sea mustard powder.

  • Fumigaclavine C (FC), an active indole alkaloid, is obtained from endophytic Aspergillus terreus (strain No. FC118) by the root of Rhizophora stylosa (Rhizophoraceae). This study is designed to evaluate whether FC has anti-adipogenic effects in 3T3-L1 adipocytes and whether it ameliorates lipid accumulation in high-fat diet (HFD)-induced obese mice. FC notably increased the levels of glycerol in the culture supernatants and markedly reduced lipid accumulation in 3T3-L1 adipocytes. FC differentially inhibited the expressions of adipogenesis-related genes, including the peroxisome proliferator-activated receptor proteins, CCAAT/enhancer-binding proteins, and sterol regulatory element-binding proteins. FC markedly reduced the expressions of lipid synthesis-related genes, such as the fatty acid binding protein, lipoprotein lipase, and fatty acid synthase. Furthermore, FC significantly increased the expressions of lipolysis-related genes, such as the hormone-sensitive lipase, Aquaporin-7, and adipose triglyceride lipase. In HFD-induced obese mice, intraperitoneal injections of FC decreased both the body weight and visceral adipose tissue weight. FC administration significantly reduced lipid accumulation. Moreover, FC could dose-dependently and differentially regulate the expressions of lipid metabolism-related transcription factors. All these data indicated that FC exhibited anti-obesity effects through modulating adipogenesis and lipolysis.

  • Ralstonia solanacearum species complex (RSSC) is a soil borne plant pathogen causing bacterial wilt on various important crops, including Solanaceae plants. The bacterial pathogens within the RSSC produce exopolysaccharide (EPS), a highly complicated nitrogencontaining heteropolymeric polysaccharide, as a major virulence factor. However, the biosynthetic pathway of the EPS in the RSSC has not been fully characterized. To identify genes in EPS production beyond the EPS biosynthetic gene operon, we selected the EPS-defective mutants of R. pseudosolanacearum strain SL341 from Tn5-inserted mutant pool. Among several EPSdefective mutants, we identified a mutant, SL341P4, with a Tn5-insertion in a gene encoding a putative NDP-sugar epimerase, a putative membrane protein with sugar-modifying moiety, in a reverse orientation to EPS biosynthesis gene cluster. This protein showed similar to other NDP-sugar epimerases involved in EPS biosynthesis in many phytopathogens. Mutation of the NDP-sugar epimerase gene reduced EPS production and biofilm formation in R. pseudosolanacearum. Additionally, the SL341P4 mutant exhibited reduced disease severity and incidence of bacterial wilt in tomato plants compared to the wild-type SL341 without alteration of bacterial multiplication. These results indicate that the NDP-sugar epimerase gene is required for EPS production and bacterial virulence in R. pseudosolanacearum.

  • The purpose of this study was to investigate the sensory characteristics of brown sauce made with different ratios of Jubak. In the brown sauce made from Jubak, the followings showed changes according to the amount of Jubak. The content of crude lipid increased, that of crude protein and moisture decreased, and that of crude ash and reduced sugar increased. Brown sauce made from Jubak contained more reduced sugar than general brown sauce, and the content of reduced sugar increased. pH increased from initial pH 4.32 to 5.42 respectively, and viscosity increased. The "L" value expressing brightness of samples had a tendency to increase with Jubak added. "a" value had a tendency to increase in case of no Jubak added, and "b" value had a tendency to decrease according to the amount of Jubak. In the sensory evaluation, color and flavor decreased and viscosity increased with the amount of Jubak. Overall, it was the highest in 0% Jubak. From the above results, an addition of 25% Jubak to brown sauce is recommended for commercial use.

  • This study investigated the feasibility of manufacturing a low-sugar wild vine jam by examining viscosity, water content, and pH, as affected by sugar and pectin content. The jams were prepared by adding various amounts of sucrose, glucose, or fructose (1.89 M, 2.34 M, 2.63 M, or 2.92 M) and/ or pectin (0%, 0.3%, 0.5%, 0.8%, or 1%) to wild vine juice and heating at $90^{\circ}C$ for 3 hrs. A higher viscosity was shown for the jam manufactured with sucrose as compared to those made with glucose or fructose, and the greater the sucrose level the higher the viscosity of the jam. The jam with 50% reduced sugar content showed a similar viscosity to the control jam, which contained only 2.92 M sucrose, when the sugar was co-added with pectin at 0.5% for the low sucrose jam, and at 0.8% for the low glucose or low fructose jams, respectively. The water content of the low sucrose jam was lower than that of the low glucose or low fructose jams, and adding pectin had no significant effect on the water content of the low sugar jam. The pH levels of the jams were not significantly different, regardless of the type and concentration of sugar, temperature, or pectin addition, and ranged between 3.6 and 3.8. Overall, the results clearly show that wild vine jam with 50% reduced sugar content and having the same viscosity as control jam, can be manufactured when pectin and sugar are added together.

  • This is a part of study on the hydrolysis of seaweed using microorganisms. A microflora sample obtained from a decayed pine tree was purified by pure culture of 4 times. As the result, 16 isolated strains were obtained from the microflora sample and then each strain was incubated in a liquid medium with sea tangle powder for 3 weeks. Ratios of reduced sugar to total sugar of 08A211, 08C221 and 08B121 strains were highest. Accordingly, these three strains were incubated in 3 different liquid media of sodium alginate, sea tangle powder, and sea mustard powder for 3 or 4 weeks. The ratios of reduced sugar to total sugar and cell growth were measured once a week. Cell growth and ratios of reduced sugar to total sugar was highest for 08B121 in all the liquid media.

  • The distribution features of recombinant human $alpha-interferon(rHuIFN-{\alpha}A)$ and $^{14}C-radiolabeled\;rHuIFN-{\alpha}A\;(^{14}C-rHuIFN-{\alpha}A)$ were investigated in ICR mice after i.v. injection. The level of $rHuIFN-{\alpha}A$ in the kidney was significantly higher than those in lung and liver at 10min after the injection. But the level was reduced significantly at 60min. The level of radioactivity in the kidney was also significantly higher than those in other organs after i.v. injection of $^{14}C-rHuIFN-{\alpha}A$, but it was reduced at much slower speed than was $rHuIFN-{\alpha}A$. These results show that interferon is distributed repidly and the kidney is the main site of distribution and metabolism of $rHuIFN-{\alpha}A$.
