At beginning the fermentation is naturally occurred by natural microbes. Fermentation techniques apply as two ways, one is fermentation to produce fermented foods and the other is preservation of the foods for longer time for future. They contain various biological active ingredient, like as vitamins. Microorganisms concerning fermentation are well known the functionalities. Each nations in the world have unique and distinct foods and dietary habits on their own specific cultures and accessible edible raw resources of plant or animal origins. Many countries have their unique traditional fermented foods based on their natural conditions. Korea has very famous traditional fermented foods, as Kimchi, fermented soybean products(Jang), fermented fish products(Jeotgal) and vinegar. In this review will discuss the overall fermented foods and typical Korean traditional fermented foods with functionalities, and future effort to enlarge into wide range of new industry.

A survey was conducted to investigate housewives' perception and consumption of Korean fermented foods marketed in Taejon. Most subjects know how to prepare Kimchi(seasoned and fermented vegetables), 65-67% can make Kochujang(fermented red pepper soybean paste), Toenjang(Korean style soysauce) and Jang-atchies(pickled basic side dishes), 56% can make Kuk-ganjang(Korean style coysauce), 45% can make Chonggukjang (fermented soybean) and 34% can make Jot-kals(salt-fermented fish products). With decreasing age(p<0.0001), not many other subjects could make other fermented foods besides Kimchi. The percentages of subjects buying fermented foods were 71.5% for Chin-ganjang(Japanese style soysauce), 51.7% Jot-kals, 27.1%Kochujang, 25.7% Chonggukjang, 20.1% Jang-atchies, 10.4% Toenjang, 5.9% Kuk-ganjang, and 3.8% Kimchi. the uounger in age, the higher the tendency to buy marketed Kimchies(p<0.05) and Kochujang(p<0.01). The resons for purchasing fermented foods were convenience (52.9%), lack of preparation knowledge(17.5%), lack of time for preparation(12.5%), and lack of space for food storage(8.2%). Subjects indicated that their reasons for mot buying were as follows : use of additives or unreliability with regard to manufacturing dates(45%), bad taste(21%), unsanitary treatment(16%) and to keep their indigenous taste(14%). They cosidered expiration dates, taste, crpteria and safety as the important standard in selecting marketed foods. Younger subjects insisted on the improvement of sanitary condition and partial change of taste to increase the consumption of fermented foods. However, older subjects thought it best to keep the taste original for more utilization of fermented foods.

Around the world, fermentation of foods has been adopted over many generations, primarily due to their commercial significance with enriched flavors and high-profile nutrients. The increasing application of fermented foods is further promoted by recent evidence on their health benefits, beyond the traditionally recognized effects on the digestive system. With recent advances in the understanding of gut-brain interactions, there have also been reports suggesting the fermented food's efficacy, particularly for cognitive function improvements. These results are strengthened by the proposed biological effects of fermented foods, including neuroprotection against neurotoxicity and reactive oxygen species. This paper reviews the beneficial health effects of fermented foods with particular emphasis on cognitive enhancement and neuroprotective effects. With an extensive review of fermented foods and their potential cognitive benefits, this paper may promote commercially feasible applications of fermented foods as natural remedies to cognitive problems.

Korean traditional fermented foods have been diversely developed to enhance taste and flavor while preserving them on a long term basis. For those furthur utilization and development, more efforts to commercialize these products focusing to the consumer's needs should be proceded. In that sence, the fermented foods might be classified into the bioproduct (biofood) and the sterilized. The former defines the non-sterilized such as Kimchi, Jeotkal (fermented fishes), and Jang (fermented soybean products) so as to include various kinds of microorganisms, enzymes and the unknown bioproducts, while the latter defines the sterilized such as soysauce and vinegars proper to the commercialization. In this paper, present R & D status has been reviewed laying stress on Kimchi, Jeotkal and Jang and the mixed fermentation system by the microflora was suggested as a Korean style model for the future R & D direction in these fields.

This review describes the diversity of Korean fermented foods and their significance as potential sources of probiotic bacteria. Fermented foods consumed in Korea are categorized according to their base material. Fermented foods such as kimchi, meju, doenjang, kangjang, jeotgal, and makgeolli are reported to have significant medicinal properties. These fermented products, which are consumed regularly by local people, are rich sources of beneficial microbes represented by several genera, including Weissella spp., Lactobacillus spp., Leuconostoc spp., Mucor, Penicillium, Scopulariopsis, Aspergillus, Rhodotorula, Candida, Saccharomyces, and Bacillus, as well as lactic acid bacteria. Fermented foods are now taken beyond the boundaries of their use as mere side dishes and are used significantly as a functional as well as medicinal foods. Fermented foods are a rich source of potential natural substances with antioxidant, anticancer, anticholesteric, antiobesitic, and antiaging properties, so that traditional fermented foods used as food supplements can impart health benefits. Publication of scientific studies on the dietary benefits of various fermented foods and growing consciousness about the potential health benefits of traditional fermented food are reflected in the scores of reports currently available in this field. Food microbiologists now have abundant opportunities to explore Korean traditional fermented foods for the isolation of new bacterial strains and to evaluate the potential applications of these strains through microbiological research.

The purpose of this study was to evaluate nutritional value of traditional fermented foods by dietary intake of university students living in Chungnam. 210 students were asked for their daily food intake using 24-hour recall method for 3 days. And daily nutrient intakes from total foods and fermented foods were analyzed and compared. The mean weight, height, and BMI of the subjects were 67.36㎏, 174.39㎝, 22.15㎏/$m^2$ in men and 53.45㎏, 161.86㎝, 20.40㎏/$m^2$ in women, respectively. The daily intakes of protein, phosphorus, and vitamin B1 were 106.82%, 137.88%, and 108.99% of the Korean RDA. However, the energy, calcium, iron, vitamin A, vitamin B2, niacin, vitamin C intakes did not reached the RDA for Koreans. The fermented food intake was 9.09% of total food intake. And the percentages of fermented food intakes were 81.53% for Kimchi and 14.75% for Chang. The vegetable protein, vegetable oil, dietary fiber, calcium, phosphorus, iron, sodium, potassium, vitamin A, vitamin B1, vitamin B2, niacin and vitamin C intakes per 1000㎉ consumption from fermented foods were significantly higher than those from total foods. The fermented food intake showed positive correlation with iron, and plant iron intakes. In conclusion, the percentage of fermented food intake was about 9% and the major items were Kimchi and alcoholi beverages in university students. Fermented food intake may be important to improve the intakes of calcium, iron and vitamin.

Human have eaten various traditional fermented foods for a numbers of million years for health benefit as well as survival. The beneficial effects of fermented foods have been resulted from complex microbial communications within the fermented foods. Therefore, the holistic approaches for individual identification and complete microbial profiling involved in their communications have been of interest to food microbiology fields. Microbiome is the ecological community of microorganisms that literally share our environments including foods as well as human body. However, due to the limitation of culture-dependent methods such as simple isolations of just culturable microorganisms, the culture-independent methods have been consistently developed, resulting in new light on the diverse non-culturable and hitherto unknown microorganisms, and even microbial communities in the fermented foods. For the culture-independent approaches, the food microbiome has been deciphered by employing various molecular analysis tools such as fluorescence in situ hybridization, quantitative PCR, and denaturing gradient gel-electrophoresis. More recently, next-generation-sequencing (NGS) platform-based microbiome analysis has been of interest, because NGS is a powerful analytical tool capable of resolving the microbiome in respect to community structures, dynamics, and activities. In this overview, the development status of analysis tools for the fermented food microbiome is covered and research trend for NGS-based food microbiome analysis is also discussed.

Fermented foods with probiotics having functional properties may provide beneficial effects on health. These effects are varied, depending on the type of lactic acid bacteria (LAB). Different probiotic LAB might have different functional properties. Thus, this study was performed to evaluate the quality of fermented sausages manufactured with functional starter cultures (Lactobacillus plantarum 115 and 167, and Pediococcus damnosus L12) and different fat levels, and to determine the optimum condition for the manufacture of these products. Medium-fat (~15%) fermented sausages reduced the drying time and cholesterol contents, as compared to regular-fat counterparts. In proximate analysis, the contents of moisture and protein of regular-fat products were lower than medium-fat with reduced fat content. The regular-fat products also had a lighter color and less redness, due to reduced fat content. Approximately 35 volatile compounds were identified in functional fermented sausages, and hexanal, trans-caryophyllene, and tetradecanal were the major volatile compounds. Selected mixed starter culture showed the potential possibility of replacing the commercial starter culture (LK30 plus) in flavor profiles. However, medium-fat fermented sausage containing selected mixed starter culture tended to be less acceptable than their high-fat counterparts, due to excess dry ring developed in the surface. These results indicate that the use of combinations of L. plantarum 115 and 167, and P. damnosus L12 as a starter culture, will prove useful for manufacturing the fermented sausage.

This study performed recognition and preference tests on hometown foods given to University students in NaePo province, which is in the northwest area of Chungnam, Korea. The results indicated that female students and people who majored in food science were less interested in hometown foods than male students or who are not majors in food science. Moreover, they preferred Korean-style foods to food from other countries. Mass media has aroused interest in hometown foods. However, hometown foods require standard recipes certain levers of autonomy for the population. Hometown foods are valuable and should be handed down the next generation through publicity. For example, Kkotgetang(blue crab soup) was the best known hometown foods followed by kkotgegang(fermented blue crab with sauce), saeujeot(salted and fermented shrimp), eorigul jeot(salted and fermented oyster with red pepper) in that orders. The most preferred food was kkokgetang(blue crab soup) followed by kkotgegang(fermented blue crab with sauce).

This survey was carried out to investigate the usage of traditional fermented foods. Questionaries were answered by 283 female adults ranging from 20 to 60 ages in Daegu city and Kyungbuk province. 39.72% of total subjects answered that they made Meju and soybean paste by themselves. There were significant differences according to income, residential area, deucation level, and family size, In the results of the preference and consumption study on traditional soybean pastes, Kimchi and salted sea foods, preference of salted sea foods was the highest, whereas the consumption of salted sea foods was the lowest. The recognition of soybean pastes and traditional foods was remarkably low. However the consumption frequency of traditional fermented foods and the recognition of soybean pastes and traditional foods were significantly increased with age.
