  • Hot pepper has anti-obesity effects by controlling appetite and reducing blood fat level. To reduce the pungency of capsaicin, red or green hot pepper juice was fermented with Bacillus licheniformis SK1230. Fermented hot pepper juice was then added into yogurt at different ratios. The pH of yogurt added with hot pepper juice was decreased from 4.61 to 4.48. Titratable acidity and counts of lactic acid bacteria were increased with increasing amount of pepper juice added. However, the viscosity was decreased significantly compared to the control. On chromaticity test, when more pepper juice was added, $L^*-value$ was decreased whereas $a^*$- and $b^*$- values were increased significantly (p<0.05). The spectrum of antimicrobial activity of yogurt was slightly changed compared to using pepper juice. Total polyphenol contents and antioxidant activity were increased with increasing amount of pepper juice added. Stirred yogurt added with fermented red pepper juice at 3% or green pepper juice at 1% showed high scores in flavor, appearance, texture, and overall acceptance in sensory test. Yogurt added with fermented pepper juice with reduced pungency showed also good palatability during storage at $4^{\circ}C$. Yogurt with added hot pepper juice can be play an important role in functional food relative to anti-obesity.

  • Two experiments were carried out on a laboratory scale. The first involved a study of the effect of green tea on characteristics of fermented juice of epiphytic lactic acid bacteria (FJLB). FJLB was treated with 50 g/L of green tea products as follows: new shoot powder (FJLB+N), leaf powder (FJLB+L), commercial powder (FJLB+P), sterilized new shoot powder (FJLB+SN), sterilized leaf powder (FJLB+SL) or sterilized commercial powder (FJLB+SP). FJLB without any additive was also prepared (Untreated FJLB). After incubation, the number of microorganisms in FJLB were studied. Subsequently, these FJLB were applied at 10 ml/kg to chopped rhodesgrass to study their effects on fermentation. Compared with untreated FJLB, the addition of green tea increased (p<0.05) lactic acid bacteria (LAB) and also aerobic bacteria counts in FJLB. At 60 d of ensiling, all the FJLB treated silages were well preserved, pH and butyric acid content were lower (p<0.001) and lactic acid was higher (p<0.001) than that of the control. Lactic acid content was significantly higher (p<0.001) with treated FJLB than with untreated FJLB. FJLB treated with sterilized green tea decreased (p<0.001) the pH and the lactic acid content was higher (p<0.001) than that in the unsterilized green tea silages.

  • Effects of various sub-ingredients (hot pepper, garlic, ginger, green onion, leek, salted and fermented anchovy juice, and sugar) on the sensory quality of Korean cabbage kimchi were investigated. Sixteen sensory attributes were selected and their intensities evaluated by 20 panelists. The kimchi had an unbarmonized taste and unpleasant flavor when fermented with individual sub-ingredients, but had a well harmonized taste when fermented with all sub-ingredients. Hot pepper, ginger and garlic contributed to reduction of the unpleasatnt taste and moldy odor. The strong garlic flavor was reduced by adding green onion and leek. Salted and fermented anchovy juice gave a palatable taste, and the overall taste was improved by adding sugar. All sub-ingredients except sugar reduced the sour tasts.

  • Effective method for the preparation of Dongchimi juice was developed by addition of NaCi, sucrose and bydrolytic enzymes before fermentation and addition on Dongchimi juice during fermentation. The radish was ground and suspended in water(1:1, w/v) with addition of spices(garlic, green onion and ginger) followed by fermentation at $25^{\circ}C$. The addition of 2% NaCi and 0.5~2.0% sucrose resulted in significant increase of solid content and it was also improved by the addition of polysaccharide hydrolyzing enzyme during fermentation. When the fermented juices of pH 5.4 of 4.4 were added by 15% of total weight before(pH 5.4 juice)and during (pH 4.4 juice) fermentation, a significant increase in solid content after 24hrs of fermentation was resulted. The combined method of addition of 2% NaCI, 1.0% sucrode, 0.1% Viscozyme and 10% of fermented juice of pH 5.4 and 4.$ before and during fermentation improved solid content, reducing sugar, color and showed little effect on viscosity. The organoleptic characteristics were also improved by the combined method.

  • In this study, cosmetic materials were developed using a new method of making juice through the fermentation of raw natural materials with microorganisms in order to supplement the advantages and disadvantages of an organic solvent extraction method and a microbial fermentation method. The natural products were selected from two colors (red, green) of paprika known to be rich in various colors and vitamins. The microorganisms used for fermentation were fermented by inoculating paprika with lactic acid bacteria (Lactobacillus plantarum) having sugar-hydrolyzed ability. First, we investigated the changes of physiologically active substances of two kinds of paprika juice and two kinds of fermented paprika juice. Total phenols content and total flavonoids content were higher in the fermented paprika juice than in the paprika juice, and especially in the fermented red paprika juice. Free radical scavenging effect and lipid peroxidation inhibitory effect were also showed an excellent antioxidative effect on paprika fermented juice, among which the effect of red paprika fermentation juice was the highest. The expression of MMP-1 in fermented red paprika juice with high antioxidant activity was inhibited by concentration-dependent expression of MMP-1 mRNA and MMP-1 protein. In the glycation experiments with aging, the anti-glycation effect of fermented paprika juice was highly inhibited by the production of advanced glycation end-products (AGEs), which was closely related to the antioxidant effect. In addition, the activity of senescence-associated ${\beta}$-galactosidase (SA-${\beta}$-gal), an indicator of cell senescence, was measured using human dermal fibroblast (HDF). The results showed that the cell senescence was inhibited when the cells were treated with fermented paprika juice. In conclusion, fermented paprika juice using lactic acid bacteria showed better antioxidative and anti-aging effects than paprika juice. Among them, fermented red paprika juice has the best antioxidant and anti-aging effect and can be applied as natural new material of antioxidant and anti-aging.

  • This study was conducted to ivestigate the quality of modeled chinese-cabbage Kimchi. The mutual action of sub-ingredients and optimum mixing conditions were examined by analyses of pH, acidity, content of vitamins, carotenes, number of total microorganism, and Lactobacilli, the activities of softening related to enzymes (polygalacturonase and ${\beta}$-galactosidase), and sensory quality during fermentation. The result about the mutual action of red pepler powder and garlic showed that the pH was decresed as concentration of garlic was higher and that of red peppler powder became lower. Kimchi had unpleasant taste and undesirable odor when the adding ratio of the peper powder and garlic was unbalanced. As the concentration of garlic became higher, the content of vitamin C in Kimchi tissue decreased while that of vitamin C in Kimchi juice increased. The contents of vitamin B1, B2 and carotene increased as the concentration of garlic became lower. The optimum mixing ratio of red pepper powder and garlic evaluated by overall eating quality was 4.66% and 3.45%, respectively. The result about the mutual action of ginger and green onion was that pH became higher as the concentration of ginger was 1.84% and that of green onion was 5.96%. The intensity of fresh taste and odor became stronger as the concentration of ginger increaed to 2.76% and that of green onion decreased to 2.98%. The balance of sour, salty and hot taste became better as the concentration of ginger increased and that of green onion decreased. The optimum mixing condition evaluated by overall eating quality was 2.94% in ginger + 2.78% in green onion. The contents of vitamin B1, B2 and C were high in this condition. The result about the mutual action of leek and salted anchovy juice was that pH became lower as the concentration of leek increased and that of salted anchovy juice decreased. Sour, hot and sweet tastes were good in the condition of leek 12%, salted anchovy juice 4.69%. Palatable, fresh taste and odor became weaker when the one of both sub-ingredients was too much little. The optimum mixing condition evaluated by overall easting quality was 9.76% in leek + 7.32% in salted anchovy juice. The contents of vitamin B1, B2, C and carotene were high in this condition and other sensory qualities were good. The result about the mutual action of salt and sugar was that pH became lower as the concentration of sugar became higher and that of salt became lower. The sweet taste was reduced of hot taste than salty taste. Palatable and fresh tastes were desirable when Kimchi fermented with less salt and more sugar. The optimum mixing condition evaluated by overall eating quality was 3.29% in sugar + 4.80% in salt. The contents of vitamin B1, B1, C and carotene were high in this condition. The result of model Kimchi fermented at 20$^{\circ}C$ was that the number of Lactobacilli in model Kimchi was higher than that of in control Kimchi. The fermentation period was extended under pH 4.0 and the contents of vitamin B1, B1,C and carotene were high through the whole edible period. The activity of polygalacturonase was low, but that of ${\beta}$-galactosidase was high during fermentation.

  • 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.

  • Italian ryegrass (Lolium multiflorum Lam.) was fractionated into leaf nutrient concentrate, fiber and deproteinised juice (DPJ). The fresh and fermented DPJs were concentrated and referred to as fresh deproteinised juice concentrate (FDPJC) and fermented deprotenised juice concentrate (FMTD DPJC). The FDPJC and FMTD DPJC were separately mixed with dried fiber and ensiled. Wilted crop silage and fresh fiber silage were also prepared from the same material crop. The nutritive value of these four silages were compared using four goats by $4{\times}4$ Latin square design. Green crop fractionation resulted lesser amount of crude protein and ash, and higher amount of neurtal detergent fiber, acid detergent fiber, cellulose and hemicellulose in fresh fiber. The pH of fresh fiber silage was lower than that of the other silages. Addition of FDPJC or FMTD DPJC to the dried fiber at ensiling did not improve the silage qualities; but all the silages were satisfactorily preserved. Goats fed these silages showed similar ruminal pH and total volatile fatty acid concentrations. But addition of FMTD DPJC was effective on increasing ruminal acetic acid concentration reducing propionic acid concentration. Ruminal n- and iso- butyric acid concentrations were proportional to that of propionic acid. High ammonia content of the silage containing FMTD DPJC was reflected to the ruminal ammonia concentration, urinary nitrogen excretion and serum urea level of goats. Inclusion of FDPJC or FMTD DPJC added 15 to 25% dry matter to the fiber silages with a little reduction in the digestibilities of most components of the silages.

  • A survey on the quality improvement and preference for green onion kimchi by Chinese and Japanese consumers was conducted by 30 Korean specialists in order to develop an improved green onion kimchi product. The long green onion shape, kimchi juice, seasonings, off-odor of fermented sea food, and stimulatory flavor of green onion were the main issues considered for the improvement of green onion product. Usage of the favorite ingredients of the Chinese and Japanese consumers was also suggested. The percentages of Chinese and Japanese who already knew green onion kimchi were 54.1% and 30.3%, respectively, whereas 46.8% of Chinese and 28.1% of Japanese have actually tried green onion kimchi in Korea. There was no significant difference in the preference for green onion kimchi between Chinese (3.25/5.0) and Japanese (3.17/5.0) consumers. For recommendations for improving the quality of green onion, Chinese consumers thought off-flavor, fibrous texture, and fermentation level were more significant while the Japanese considered red color, various taste, MSG content, and length of green onion. Seasoned tofu with green onion and rice were suggested as complementary foods to green onion kimchi by the Chinese and Japanese, respectively.
