  • 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 conducted to standardize ingredient ratio and preparation method of mafor traditional special kimchies in kyungsang province, korea. There were about 35 varieties of special kimchi in Kyungsang province. Six varieties of them such as burdock kimchi, wild leek kimchi, green thread onion kimchi, perilla leaf kimchi, Godulbaegi(Korean wild lettuce) kimchi, and red pepper leaf kimchi were selected, because they tasted good and the physiological functions of their main ingredients were excellent. The ingredient ratios of the selected special kimchi were standardized through surveying hereditary preparation of some families in kyungsang province and using the literatures including cooking books. The standardized ingredient ratio of the burdock kimchi was 15.1 pickled anchovy juice, 6.8 red pepper powder, 5.7 garlic, 2.2 ginger, 18.0 rice flour paste, 13.5 green thread onion, and 1.2 sesame seed in proportion to 100 of burdock. The standardized preparation step of the selected special kimchies was similar except some preprocessing methods of main ingredients. The diagonally cut-up burdock ws usually parboiled or soaked in salted water, then it was mixed with the other ingredients. Wild leek and green thread onion were usually pickled with salt or pickled anchovy juice. Sometimes the green thread onion pickled was dried in the sun. General preprocessing of perilla leaf, Korean wild lettuce, and red pepper leaf was soaking them in salted water for about 5-10 days. Sometimes red pepper leaf was heated with steam and dried in the sun, then it was mixed with the other ingredients.

  • Kinds of ingredient of Chinese cabbage kimchi were standardized by the sensory evaluation, chemical properties, and functional properties of antimutagenic effect and inhibitory effect on the growth of AGS human gastric adenocarcinoma cells. The kinds of ingredient in control kimchi from the previous study, but Gueun salt instead of Chunil salt, exhibited better overall acceptability and less moldy smell and moldy flavor than any other kinds of ingredient added chinese cabbage kimchi in the taste. The kimchi showed chemical properties of properly fermented kimchi, pH 4.3 and acidity 0.72% and also contained 1.6 g% reducing sugar and $2.2{\times}10^8\;CFU/mL$ Leuconostoc sp. The juice of standardized kimchi with the above kinds of ingredient showed not only high antimutagenicity (74%) against aflatoxin $B_1$ in Salmonella typhimurium TA100 but also strong inhibitory effect (60%) on the growth of AGS human gastric adenocarcinoma cells in SRB assay. From the taste, chemical and functional properties, the standardized kinds of ingredient were Youngyang taeyangcho red pepper powder, anchovy juice, Gueun salt, Garak sin 1 ho Chinese cabbage.

  • Eight commercially packaged kimchi products were examined over 15 days of storage at $4^{\circ}C$ to evaluate the occurrence of Hafnia alvei (H. alvei). Additionally, 7 saeujeot products, as a possible ingredient source, were analyzed to examine the bacteria's origin. Over the storage period, kimchi samples had decreasing pH levels, which stabilized at pH 4.2; acidity increased to $0.9{\pm}0.1%$. Lactose-nonfermenting bacteria, which H. alvei belongs to, gradually reduced in numbers over the kimchi storage. However, the relative frequency of H. alvei to lactose-nonfermenting bacteria tended to increase. From the kimchi samples, 58 H. alvei-presumptive colonies were selected. Forty three colonies turned out to be H. alvei and 15 colonies were identified as other strains or uncertain identifications when the API 20E system was used. From further test, 3 of the 43 colonies were H. alvei (-) against the phage test. Finally, H. alvei was isolated from saeujeot, indicating that this ingredient can be an originating source of H. alvei in kimchi.

  • To enhance the antimutagenic and anticancer activities of chinese cabbage kimchi, 13 kinds of kimchi, which were different kinds and levels of sub-ingredient added kimchi, were prepared and fermented at 15℃ for 1 day and then at 5℃ up to pH 4.3. The antimutagenic effects of the methanol extracts of the kimchi were studied by using Ames mutagenicity test in Salmonella typhimurium TA100 and SOS chromotest in E. coli PQ37. Among the kimchi samples, high ratio of red pepper powder(7%) and garlic(2.8% or 5.2%) added kimchi, 1% chinese pepper powder added kimchi and organic cultivated chinese cabbage kimchi significantly reduced(p<0.05) the mutagenicity induced by aflatoxin B1(AFB1) in Ames test and SOS response against N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) in SOS chromotest, and also the kimchi inhibited more effectively(p<0.05) the survival and growth of AGS human gastric adenocarcinoma cells than the standarized kimchi on the SRB assay, MTT assay and growth inhibition test. These results suggest that the antimutagenic and anticancer activites of kimchi can be increased by the sub-ingredients such as organic cultivated chinese cabbage, red pepper powder, garlic and chinese pepper powder.

  • A polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) technique followed by sequencing of the 16S rDNA fragments eluted from the bands of interest on denaturing gradient gels was used to monitor changes in the bacterial microflora of two commercial kimchi, salted cabbage, and ingredient mix samples during 30 days of fermentation at $4^{\circ}C$ and $10^{\circ}C$. Leuconostoc (Lc.) was the dominant lactic acid bacteria (LAB) over Lactobacillus (Lb.) species at $4^{\circ}C$. Weissella confusa was detected in the ingredient mix and also in kimchi samples throughout fermentation in both samples at $4^{\circ}C$ and $10^{\circ}C$. Lc. gelidum was detected as the dominant LAB at $4^{\circ}C$ in both samples. The temperature affected the LAB profile of kimchi by varing the pH, which was primarily caused by the temperature-dependent competition among different LAB species in kimchi. At $4^{\circ}C$, the sample variations in pH and titratable acidity were more conspicuous owing to the delayed growth of LAB. Temperature affected only initial decreases in pH and initial increases in viable cell counts, but affected both the initial increases and final values of titratable acidity. The initial microflora in the kimchi sample was probably determined by the microflora of the ingredient mix, not by that of the salted cabbage. The microbial distributions in the samples used in this study resembled across the different kimchi samples and the different fermentation temperatures as the numbers of LAB increased and titratable acidity decreased.

  • 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 the proper ingredient ratios of chinese cabbage kimchi by the sensory evaluation, chemical properties, and functional properties of antimutagenic effect and inhibitory effect on the growth of cancer cells from the ratios obtained from literatures. The standardized ratios of ingredient from the literatures was 13.0 of radish, 2.0 of green onion, 3.5 of red pepper powder, 1.4 of garlic, 0.6 of ginger, 2.2 of anchovy juice, 1.0 of sugar and the final salt concentration 2.7 in the proportion of 100 salted chinese cabbage. The standardized ratio of the ingredients exhibited better overall acceptability and less moldy smell and moldy flavor than any other ratio of ingredient in the sensory evaluation. The standardized kimchi with the above ratios of the ingredients, at final salt concentration of 2.5%, showed high reducing sugar contents and Leuconostoc sp. counts. All juices of the chinese cabbage kimchi showed not only high antimutagenicity against aflatoxin $B_1$ in Salmonella typhimurium TA100 but also strong inhibitory effect on the growth of AGS human gastric adenocarcinoma cells in SRB assay, especially these functional properties were the most effective at each standardized ratio of the ingredients. From the taste, chemical and functional properties, the standardized ratios of ingredients was 13.0 radish, 2.0 green onion, 3.5 red pepper powder, 1.4 garlic, 0.6 ginger. 2.2 anchovy juice, 1.0 sugar and the final salt concentration 2.5 in the proportion of 100 salted chinese cabbage.

  • Fibrionolytic activity(FA) of kimchi in rat and FAs of water and methanol extracts of kimchi ingredient were determined using fibrin plate method to see where the active principles for FA are present in kimchi. Nine Sprague-Dawley per each group were fed diet containing 3, 5 or 10% of freeze dried kimchi for 6 weeks. The FA of plasma obtained from 10% kimchi group showed stronger FA than that of control. FAs of 3 and 5% kimchi group were not noticeable. FA from methanol extract of kimchi was approximately 6 times higher than that from water extract assuming that the active material may be present in a fat soluble fraction. From water extract of kimchi ingredients, dropwort, green onion, radish and baechu showed FA in descending order. And from methanol extracts, red pepper powder, radish, green onion and baechu showed FA in decending order. The Fa of methanol extract of red pepper powder was the most noticeable among samples.

  • This research was performed to investigate the potential use of Capsella bursa-pastoris (L.) as an ingredient to improve the biological function and flavor of kimchi. The quality characteristics were studied for kimchi with or without Capsella bursa-pastoris (L.) Medicus (CBM kimchi) during fermentation for 25 days at $10^{\circ}C$. The pH changes of CBM kimchi were slower than those of control but did not show any significant difference after addition of Capsella bursa-pastoris (L.) Medicus during fermentation. The titratable acidity of CBM kimchi was higher than that of control. The log number of total bacteria was lower about 1.5 $log_{10}$ cycle in CBM kimchi than in control during fermentation. However, lactic acid bacteria did not show significant difference between CMB kimchi and control. Sensory qualities of kimchi such as color, taste, flavor and overall acceptability were significantly improved by addition of 3% Capsella bursa-pastoris (L.) Medicus(p<0.05).
