What is the origin of kimchi and what changes did it go through to become the kimchi of today? Also, what makes kimchi different from other pickled vegetables such as Chinese paochai, Japanese tsukemono, and Western pickles, and sauerkraut, and what is the identity of kimchi? This study is the result of thought on these fundamental questions about kimchi which is the only pickled vegetable distributed around the world that uses a fermented and ripened animal seasoning called jeotgal (salted marine life) to dramatically improve its umami taste and nutritional value, thereby securing its uniqueness. Kimchi has further evolved into a unique and high-quality pickled vegetable through the use of its specialized seasoning, adopting a composite fermentation mechanism and absorbing new ingredients such as red pepper. It is expected that this paper will invigorate the discussion on the firm establishment of the identity of kimchi and the future direction that it may take.

Fermented beverage using lactic acid bacteria isolated from kimchi was investigated. Lactic acid bacteria KL 1, KD 6, KL 4 strains from kimchi, or obtained Lactobacillus acidophilus, Lactobacillus plantarum, Leuconostoc mesenteroides with and without yeast(Saccharomyces cerevisiae) were inoculated in fruit vegetable juice for single and mixed culture fermentation. During the fermentation by bacterial strain and yeast for 1~3 days at 30oC, various fermentation behaviors were observed. The growth rate of mixed culture of KL 1 and yeast was higher than that of single culture by KL 1 alone during the fermentation. The amount of organic acid produced by the mixed culture fermentation of KL 1 and yeast was 0.82%(3 day) or 0.58%(1 day) and with the final pH of 3.3(3 day) or 4.2(1 day). These mixed culture systems of isolated strains or other bacterial strains had almost similar results of growth rate and acid production. Among several bacterial strains, KL 1 was suitable for the mixed culture fermentation with yeast in terms of desirable fermentation behavior and organoleptical quality. The selected strain, KL 1 was identified as Leuconostoc spp. through the series of tests on carbohydrate fermentation and biochemical characteristics.

In this study, the bacterial community of galchi-baechu kimchi was determined using culture-based and culture-independent techniques (next generation sequencing:NGS), and showed discrepancies between results. Weissella koreensis and Pediococcus inopinatus were the dominant species according to the NGS results, while Bacillus species and P. inopinatus were dominant in the culture-dependent analysis. To identify safe starter candidates, sixty-five Bacillus strains isolated from galchi-baechu kimchi using culture-dependent methods were evaluated for their antibiotic resistance, presence of toxin genes, and hemolytic activity. Strains were then assessed for salt tolerance and protease and lipase activity. As a result, four strains-B. safensis GN5_10, B. subtilis GN5_19, B. velezensis GN5_25, and B. velezensis GT8-were selected as safe starter candidates for use in fermented foods.

The purpose of this study was to investigate American's perception and preference for Korean kimchi. A questionnaire was used to examine the perceptions of 126 males (40.4%) and 186 females (59.6%) residing in Illinois and California. Approximately 68% of the respondents had eaten Korean food. The perception of kimchi was the highest with a mean of 3.62. The respondents felt that the "Kimchi is a good side dish with cooked rice", "Kimchi (with garlic) prevents SARS", which was significantly different (M=3.06, p< .001), and "Kimchi prevents adult diseases" (M=3.24, p< .01). When evaluating the different kinds of kimchi, onion juice kimchi had the most preferred taste and also the highest overall acceptability (M=5.50, p< .05) of the second days. In the sensory evaluation by kimchi use, the best taste (p< .001) was in the order of kimchi pizza (M=6.58), kimchi dumplings (M=6.40), and kimchi chicken a'laking (M=6.33). The order for overall acceptability (p< .001) was kimchi dumplings (M=6.30), kimchi pizza (M=6.25), kimchi bacon roll, kimchi fried rice, and kimchi chicken a'laking (M=6.17).

Kimchi is a traditional Korean fermented vegetable probiotic food. The use of high quality ingredients and predominant LAB (lactic acid bacteria)-whether it be ambient bacteria or adding starters, low temperature and facultative anaerobic condition for the fermentation are important factors for preparing kimchi with better taste and functionality. The predominated LAB genera are Leuconostoc, Lactobacillus, and Weissella in kimchi fermentation. The representative species are Leu. mesenteroides, Leu. citrium, Lab. plantarum, Lab. sakei, and Wei. koreensis. Kimchi, especially the optimally fermented kimchi, has various health benefits, including control of colon health, antioxidation, antiaging effects, cancer preventive effect, antiobesity, control of dyslipidemic and metabolic syndrome, etc.; due to the presence of LAB, various nutraceuticals, and metabolites from the ingredients and LAB. The kimchi LAB are good probiotics, exhibiting antimicrobial activity, antioxidant, antimutagenic and anticancer effects, as well as immunomodualatory effect, antiobesity, and cholesterol and lipid lowering effects. Thus, kimchi ingredients, LAB, fermentation methods, and metabolites are important factors that modulate various functionalities. In this review, we introduced recent information showing kimchi and its health benefits in Korean Functional Foods (Park & Ju 2018).

Synthetic nitrite is considered an undesirable preservative for meat products; thus, controlling synthetic nitrite concentrations is important from the standpoint of food safety. We investigated 1,000 species of microorganisms from various kimchi preparations for their potential use as a starter culture for the production of nitrites. We used 16S rRNA gene sequence analysis to select a starter culture with excellent nitrite and nitric oxide productivity, which we subsequently identified as Staphylococcus hominis subspecies hominis WiKim0113. That starter culture was grown in NaCl (up to 9%; w/v) at 10℃-40℃; its optimum growth was observed at 30℃ at pH 4.0-10.0. It exhibited nonproteolytic activity and antibacterial activity against Clostridium perfringens, a bacterium that causes food poisoning symptoms. Analysis of Staphylococcus hominis subspecies hominis WiKim0113 with an API ZYM system did not reveal the presence of β-glucuronidase, and tests of the starter culture on 5% (v/v) sheep blood agar showed no hemolytic activity. Our results demonstrated the remarkable stability of coagulase-negative Staphylococcus hominis subspecies hominis WiKim0113, especially in strain negative for staphylococcal enterotoxins and sensitive to clinically relevant antibiotics. Moreover, Staphylococcus hominis subspecies hominis WiKim0113 exhibited a 45.5% conversion rate of nitrate to nitrite, with nitrate levels reduced to 25% after 36 h of culturing in the minimal medium supplemented with nitrate (200 ppm). The results clearly demonstrated the safety and utility of Staphylococcus hominis subspecies hominis WiKim0113, and therefore its suitability as a starter culture.

The purpose of this study is to examine the Western perspective on the food and food culture of Modern Times in Korea (from the late of Joseon Dynasty until Japanese colonial era). Literature and written records were analyzed. This analysis revealed that the heart of the mill in this period involved rice, and that a common beverage was sungnyung made from boiled scorched rice (in contrast to tea as the common beverage in Japan or China). The most important subsidiary food in Joseon was vegetables, especially Kimchi. Westerners viewed Kimchi as a smell symbolizing Joseon and their meal times. Even though both Kimchi and cheese are fermented food, just like Westerners could not stand the smell of Kimchi, Koreans viewed the smell of cheese unpleasant. Westerners viewed German sauerkraut as Western food counterpart to Kimchi, as sauerkraut is also fermented food made of cabbage. Regarding the eating of dog meat in Joseon, most Westerners viewed it as brutal; however some interpreted it as a difference in food culture. In addition, the eating of raw fish and its intestines felt crude to Westerners. The biggest difference between Joseon's food and Western food was that Joseon had no dairy products and no sugar. The most highly preferred fruit for Westerners was the persimmon, and ginseng was already widely recognized and recorded as a medicinal plant. Joseon's desserts were also favorably evaluated. In contrast, the excessive gluttony, heavy drinking, and unsanitary conditions in Joseon were problems pointed out in many records.

The effect of methanol soluble fraction(MSF) of kimchi on the proliferating and differentiating activity of normal rat mammary epithelial cells or organoids in culture were studied. Reconstituted basement membrane, Matrigel, supported the growth and development several different multicellular structures from mammary organoids. The five type colonies of multicellular structures, stellate, ductal, webbed, squamous, and lobulo-ductal colonies, were observed in Matrigel culture. In methanol extract groups, webbed colonies were more and squamous colonies were less than control group. and the lobulo-ductal colonies which is known that it formed in well differentiated mammary epoithelial cells were developed more in MSF treated group than control group. These results showed that methanol extract of kimchi affected on the proliferation and differentiation of normal rat mammary epithelial cells cultured in serum free medium condition.
