Effects of kimchi and its ingredients, vitamin C and $\beta$-sitosterol on the growth of Helicobacter pylori were investigated. Three kimchi variations were studied: a standard recipe (kimchi I) and two functional variations for cancer prevention and treatment made with organically grown ingredients (kimch II and III). Methanol extracts and juices from kimchi I and III did not inhibit the growth of H. pylori. However, 10 mm and 12 mm inhibition zones were formed by methanol extract and juice from kimchi II, which had higher concentrations of red pepper powder (RPP) than those of kimchi I and III. Among the major kimchi ingredients, methanol extracts of RPP, garlic and ginger substantially inhibited the growth of H. pylori. The maximal inhibition zone (30 mm) was attained with garlic treatment. Inhibitory effects of the RPP, garlic and the sub-ingredient mixture (prepared with radish, garlic, RPP, ginger, green onion, sugar and fermented anchovy juice) on H. pylori were decreased by lactic acid bacteria fermentation. Neither the fermented garlic nor the fermented sub-ingredient mixture inhibited the growth of H. pylori. But, the inhibition Bone of fermented RPP was 12 mm, which was less than the 16 mm inhibition zone formed by the non-fermented RPP. Vitamin C and $\beta$-sitosterol which are known to be functional active compounds of kimchi also showed no inhibitory effect on the growth of H. pylori after 3 days of incubation. Further study is needed to determine why the inhibitory effect is removed or decreased by lactic acid fermentation, and to determine if fresh kimchi and lactic acid bacteria of kimchi can inhibit the growth of H. pylori.

This study was conducted to standardize ingredient ratios of wooung kimchi. The ingredient ratios of model wooung kimchiwere determined by the survey in Pusan and Kyungnam province and using the literatures including cooking books. Several kinds of wooung kimchi were prepared by adjusting the ingredient ratios fo the model wooung kimchi within standard deviation. The wooung kimchi with different ingredient ratios were fermented for 6 days at 15$^{\circ}C$. The chemical, microbial and sensory properties of the wooung kimchi were investigated. There was little change in pH but the counts of lactic acid bacteria were decreased, as the ratio of pickled anchovy juice became high. The wooung kimchi adding 9.4% pickled anchovy juice obtained high score in appearance and overall acceptability. The counts of lactic acid bacteria were increased in wooung kimchi adding 5% red pepper powder, and there was obtained better result in appearance, texture and overall acceptability than the other groups. The activity, reducing sugar and counts of lactic acid bacteria were increased, as the ratio of glutinous rice paste became high. The wooung kimchi including 6% glutinous rice paste showed the highest score in overall acceptability. The fermentation process of wooung kimchi accelerated, as the ratio of garlic became high. The wooung kimchi adding 3% garlic showed good appearance and acceptability. In addition to these, the addition of 1.3% ginger ehhanced the appearance, texture and overall acceptability fermented anchovy juice, 5.0% red pepper powder, 6.0% glutinous rice paste, 3.0% crushed garlic and 1.3% crushed ginger.

This study was undertaken to evaluate the effects of green and taste teas on the in-vitro antimicrobial activity and vacuolating toxin titer of Helicobacter pylori. Crude aqueous extracts prepared by adding 2 g of tea leaf or powder to 100 ml of boiling distilled water, and sterilized by passing through a 0.22 $mutextrm{m}$ membrane filter. Green tea, coffee, and ginger tea showed bactericidal activity on H. pylori within 3 hours. Black tea and ssangwha tea also showed bactericidal activity on H. pylori in 24 hours. Arrowroot tea show no bactericidal effect on H. pylori after 48 hours. Two fold diluted green tea and coffee decreased(1/10,000cfu) the growth of H. pylori in 24 hours, but the two fold diluted black tea, ssangwha tea, and ginger tea showed suppression effect upon of(1/10cfu) H. pylori in 24 hours. The two-fold and 10-fold diluted green tea, coffee and two-fold diluted black tea abrogated the vacuolating toxin titer of H. pylori, but the two-fold and 10-fold diluted ginger, ssangwha, ginseng, and arrowroot tea only reduced the vacuolating toxin titer of H.pylori from 1/2 to 1/8. These result suggest that green tea and coffee have effective antibacterial or bactericidal effects on H.pylori, and that they also have a neutralization effect upon the vacuolating toxin of H.pylori.

This study investigated changes in the quality and antioxidant activity of soy sauce with added Saccharina japonica powder (FSP). Soy sauce was prepared with acid-hydrolyzed soy sauce, brewed soy sauce, honey, ginger, garlic, dried red pepper, ${\gamma}$-aminobutyric acid (GABA)-enriched sea tangle fermented in lactic acid, and 1% or 3% S. japonica powder by soy sauce volume. The color, pH, microbiology, amino nitrogen, free amino acids, antioxidant activity, and sensory qualities of the soy sauce were evaluated. There were no significant differences in the general characteristics or antioxidant activity. However, the addition of FSP to the soy sauce enhanced the delicate flavor. Furthermore, soy sauce containing FSP had higher levels of GABA (50 mg/100 mL), a biofunctional ingredient. Therefore, the development of seasoning soy sauce with enhanced functionality seems possible.

This feeding experiment was conducted to investigate the effects of dietary inclusion of various additives on growth performance, hematological parameters, fatty acid composition, gene expression and histopathological changes in juvenile olive flounder (Paralichthys olivaceus). Eleven isonitrogenous (49% crude protein) and isolipidic (10% crude lipid) experimental diets were formulated: no additives (Con); 5% kelp meal (Ke); 10% krill meal (Kr); 1% garlic powder (Ga); 1% citrus meal (Ci); 3% onion powder (On); 1% ginger powder (Gi); 1% mugwort powder (Mu); 1% licorice powder (Li); 1% wasabi powder (Wa); and a mixture (Mix) of these additives. Three replicate groups of juvenile flounder (average weight of 8.5 g) were fed one of the experimental diets to visual satiety twice a day for 15 weeks. The dietary inclusion of additives did not affect survival, weight gain, specific growth rate feed efficiency, daily feed intake, daily protein intake, protein efficiency ratio, hepatosomatic index and visceralsomatic index of the fish. Plasma triglyceride levels were significantly lower in fish fed the Ke, Ga, On, Gi, Mu, Li, and Mix diets than in fish fed the control diet. Plasma glucose, glutamic oxaloacetic transaminase and total cholesterol did not differ among dietary treatments. No significant difference was observed in fatty acid composition and lipid content of the dorsal muscle in fish fed the experimental diets. Myosin gene expression did not differ significantly among treatments after 5 weeks but was significantly lower in fish fed the Kr, Ci, Li, and Mix diets than in control group after 15 weeks. Histopathological analysis showed mild gill hyperplasia and mild necrosis of liver parenchymal cells in several individuals of each experimental group. These conditions were also observed in the control group and were not thought to be related to the inclusion of feed additives. The present findings indicate that the dietary inclusion of additives did not affect growth performance, fatty acid composition, gene expression, and histopathological changes in juvenile flounder. However, plasma triglyceride content may be reduced by supplementation with 5% kelp meal, 3% onion powder, 1% garlic powder, 1% ginger powder, 1% mugwort powder, and the additive mixture.

The aim of this study is to examine the influences of spices on the amounts and compositions of volatile compounds released from cooked beef patty. Beef patty with 0.5% of spice (nutmeg, onion, garlic, or ginger powder, w/w) was cooked by electronic pan until they reached an internal temperature of $75^{\circ}C$. A total of 46 volatile compounds (6 alcohols, 6 aldehydes, 5 hydrocarbons, 6 ketones, 9 sulfur compounds, and 14 terpenes) from cooked beef patties were detected by using purge-and-trap GC/MS. The addition of nutmeg, onion, or ginger powder significantly reduced the production of the volatile compounds via lipid oxidation in cooked beef patty when compared to those from the control. Also, the addition of nutmeg and garlic powder to beef patty generated a lot of trepans or sulfur volatile compounds, respectively. From these results, the major proportion by chemical classes such as alcohols, aldehydes, hydrocarbons, ketones, sulfur compounds, and terpenes was different depending on the spice variations. The results indicate that addition of spices to the beef patty meaningfully changes the volatile compounds released from within. Therefore, it can be concluded that spices can interact with meat aroma significantly, and thus, the character of each spice should be considered before adding to the beef patty.
