Effects of sangwhang mushroom (Phellinus linteus) extract on quality and functionality of ramyon (deep-fried noodle) were investigated by adding 17.5(v/w; II) and 35%(v/w; III) sangwhang mushroom extracts. Although little differences were generally observed in chemical compositions of ramyon samples II, III, and control, potassium contents of samples II and III were lower than control. Content of $(1{\rightarrow}3),\;(1{\rightarrow}4)\;and\;(1{\rightarrow}6)-{\beta}-D-glucan$, major functional component of sangwhang mushroom, increased in proportion to amount of extract added, 2.04 and $3.69{\mu}g/g$ in samples II and III, respectively, much higher than $0,09{\mu}g/g$ of control. Lightness (L) decreased, whereas redness (a) and yellowness (b) increased with increasing amount of extract added. Ramyons containing extract showed higher preference than control in texture analysis (hardness and tension) and sensory evaluation (taste and texture).

The independent anoxic reactor was introduced in biological aerated filters as the regulation of water quality requirement, especially total nitrogen, had been strengthened. The process studied in this work was upflow $Biobead^{(R)}$ process which was used commercial invented for removal of organic materials and nitrification. For the purpose of evaluating the independent anoxic reactor, PCR-DGGE, of the molecular biological methods, was performed. Two types of nitrite reductase genes were selected. One is nirS represented cytocrome $cd_1$ nitrite reductase gene and the other is nirK represented Cu-containing nitrite reductase gene. Denitrifier community in the independent anoxic reactor was analyzed with PCR-DGGE using these two denitrifying functional genes. As the result of the PCR, only nirS gene was detected between nirS and nirK. With the result of the DGGE, specific bands became strong, as the operating days were longer, nitrate loading rate was increased. otherwise those of the initial activated sludge showed various bands. In the consequence of the sequence of DGGE bands, various denitrifiers were sequenced in the initial activated sludge, while specific denitrifiers like alcaligenes faecalis were predominant in the anoxic reactor. Consequently, introduction of the independent anoxic reactor made it possible to achieve 96% denitrification efficiency, and was proper for the modification of BAF process.

The raw water DOC contained 39.3% of hydrophilics, 42.9% of hydriophobic, and 17.8% of transphilic. The hydrophobic fraction in this raw water was mostly fulvic acid. Fulvic acid comprised of 62% and the rest was humic acid(38%). There was more carboxylic acid functional group(64%) than phenolic group(36%). HPI-N and HPI-C comprised of 17% and 22% in the hydrophilic portion, respectively. The fouling mechanisms on the membrane surface and into its porous structure were analyzed in terms of several kinetic models. In order to analyze the fouling kinetics, the various kinetic models described in this paper were used to fit the experimental results. The kinetic models and kinetic constants obtained for each operation condition. The permeate flux was rapidly declined by simultaneous pore blocking and cake formation. Also, the permeate flux declined with decreasing internal pore size resulted from organic deposition into the membrane pore. The results of the membrane fouling test using UF membrane according to NOM fractions. HPI-N caused more fouling than HPI-C. Humic acid caused more fouling than fulvic acid probably due to higher adsorption capacity. Since humic acid has higher adsorption capacity than fulvic acid, it would be more adsorbed onto the membrane pores.

This study investigated the quality characteristics and biological activities, such as antioxidant, whitening, anti-diabetes, and anti-inflammatory activities, of yellow garlic, by simplify processing time and manufacturing process compared with black garlic. Extracts were prepared various ratios of water and ethanol solvent [water : ethanol (v/v)=100:0, 70:30, 50:50, 30:70, 0:100] from yellow garlic. Alliin content of yellow garlic showed no difference compared with fresh garlic, whereas S-allyl cysteine content of yellow garlic was higher than that of fresh garlic. Alliin content of yellow garlic extracts increased in an ethanol concentration-dependent manner. Total phenol and flavonoid contents were highest in 100% ethanol extract. DPPH and ABTS radical scavenging abilities did not show significant differences among 0~70% ethanol extracts, whereas 100% ethanol extract showed the highest contents of 93.45% and 91.46%, respectively. Tyrosinase and ${\alpha}$-glucosidase inhibitory activities were also highest in 100% ethanol extract, but did not show significant differences among the extract solvents. Water and ethanol extracts from yellow garlic showed anti-inflammatory effects by modulating production of NO and cytokines at a concentration of $100{\mu}g/mL$. We suggest that yellow garlic has antioxidant, whitening, anti-diabetes, and anti-inflammatory activities and can be used as a functional material similar to black garlic.

In this study, the characteristics of alcohol fermentation using Elaeagnus multiflora juice were studied under static fermentation condition in an effort to develop new types of functional wine. After 9 days of fermentation at $25^{\circ}C$, the pH, soluble solids, reducing sugar, viable cell numbers, and alcohol contents were shown to be 3.32~3.33, $7.8{\sim}9.0^{\circ}C$, 29.84~31.05 g/L, 7.26~8.73 cfu/mL, and 11.0%, respectively. The heat treated juice exhibited significantly higher antioxidant activity than untreated juice while the soluble phenolic and flavonoid contents became higher. Also, the fermented wine after the heat treated at $120^{\circ}C$ for 30 min contained free sugar such as fructose (0.42 g/L) and glucose (0.09 g/L), major organic acids such as lactic acid (7.32 g/L), malic acid (2.59 g/L), succinic acid (2.16 g/L), and oxalic acid (3.08 g/L), and major flavanols and phenolic acids such as catechin (99.45 mg/L), epicatechin (264.55 mg/L), epigallocatechin (82.19 mg/L), gallic acid (6.44 mg/L), and salicylic acid (60.53 mg/L). In addition, DPPH radical and ABTS radical scavenging activities and FRAP assay results were 70.47%,, 65.93%, and 1.254, respectively. These results suggest that it is possible to produced a new type of wine using Elaeagnus multiflora fruits.
