Korean traditional fermented milk, Tarak, came down from the Koryo dynasty according to Korean ancient cookbook SoowoonJaabaang, which was written by Taakjunggong, Yoo Kim around AD 1500. Tarak is generally refers to milk or dairy products. Three theories on 'Tarak' revealed in this study are as follows: 1) it has been derived from Dolgwol language, tarak, 2) it has originated in Mongolian language, Topar(tarague), meaning horse's milk and 3) it originated in Tarak mountain located in Hanyang, which was capital of Chosun. In Mongolia, fermented milk has been called as Tarak and it has been called as tar by Yakuts tribe who are nomads in Sakha. The common part, tar, of these words is said to be the term representing the origin of the fermented milk coming from the central Asia. Therefore, Korean Tarak seems to be part of the central Asian culture that flowed into the Korean peninsula. The manufacturing method of Mogolian Topar(tarague) is similar to those of Tarak found in the SoowoonJaabaang. This research revealed that Korean traditional fermented milk, Tarak, is thought to be affected by the central Asia, especially Mongolia.

Lactic acid bacteria had been widely utilized in fermented foods such as fermented dairy products, traditional sauces, kimchi, fermented sausages, medicines or probiotic feed additives for a long time. LAB are also widely distributed in the mammalian gastrointestinal tracts, oral cavity, vagina, and various foods or soils. The most familiar examples of using LAB would be the fermented milk products, and those had become one of the favorite foods in Korea f3r more than 34 years of history. The main benefits of the fermented milk products were originally the improvement of the balance of intestinal flora to control diarrhea and congestion disorders, and gradually, they were chosen by the consumer preference of the taste. The very beginning of the fermented milk products in Korea was the Yakult type products in 1971, and it was the commencement of the solid foundation of the dairy industry and the understanding beneficial effect of probiotic yogurt. After middle of 80's, stirred type fermented milk products had been firstly produced, and it was the time that the domestic dairy industry took root in Korea. From 90's, functional fermented milk products were produced, and drink type yogurt sales a mount increased drastically, and these products began to be chosen not only with the values of nutrition but also with physiological functions. The health claims are classified into intestinal health, gastric health and hepatic health. The prospects for the Korean market are as follows; The majority of leading products would be the premium functional yogurt products as it was last year. It is because the sales of lower cost products shows slow-down, and industries tend to increase the commercial advertisements of premium functional yogurt products through mass media. These tendencies would make the market situation become more competitive.

The Mongolian milk processing technology has a specific characteristic as a result of the living habits of Central Asian nomads. There are many kinds of milk products in Mongolia due to their processing activity used milk from various dairy animal species. Mongolia has over 30 kinds of dairy products and fermented milk products which are occupied more than 36% of the Mongolian dairy products. Herdsmen who engaged extensive livestock production have specific methods to conserve and prepare the starter culture of fermented milk products in nomadic condition. Specifically, Mongolian lactic starter cultures were prepared from keeping milk products and specific wild plants. Nowadays, over 5 kinds of wild plants such as Rheum undulatum L. Rheum ribes L, Rumex acetosa L. Artemisa sibersena L, Artemisa vulgare are used for lactic starter preparing. Traditional processing methods of the Mongolian fermented milk products are based on the scientific basis and there are easy to learn and operate.

The objective of this study was to identify the coccoidal bacteria present in 188 samples of fermented yaks’, mares’ and cows’ milk products collected from 12 different regions in Mongolia. Furthermore, we evaluated the fermentation properties of ten selected isolates of the predominant species, Streptococcus (S.) thermophiles, during the process of milk fermentation and subsequent storage of the resulting yoghurt at 4℃. Overall, 159 isolates were obtained from 188 samples using M17 agar. These isolates were presumed to be lactic acid bacteria based on their gram-positive and catalase-negative properties, and were identified to species level using 16S rRNA gene sequence analysis. These coccoid isolates were distributed in four genera and six species: Enterococcus (E.) durans, Enterococcus (E.) faecalis, Lactococcus (Lac.) subsp. lactis, Leuconostoc (Leuc.) lactis, Leuconostoc (Leuc.) mesenteroides. subsp. mesenteroides and S. thermophilus. Among these S. thermophilus was the most common species in most samples. From evaluation of the fermentation characteristics (viable counts, pH, titratable acidity [TA]) of ten selected S. thermophilus isolates we could identify four isolates (IMAU 20246, IMAU20764, IMAU20729 and IMAU20738) that were fast acid producers. IMAU20246 produced the highest concentrations of lactic acid and formic acid. These isolates have potential as starter cultures for yoghurt production.

Camel milk has a significant and pivotal role in the diet of people residing in semi-arid and arid regions. Ever since ancient times, marketing of camel milk has remained insignificant due to nonexistence of processing amenities in the camel nurturing areas, hence the utilization of unprocessed camel milk has continuously remained limited at family level by the nomads. Due to the superior medicinal values and health promoting effects, incredible growth in the demand of camel milk and dairy products have been noticed all over the world during last two decades. Such emergence has led dairy industry to provide diversified camel dairy products to the consumers with superior nutritional and functional qualities. In contrast to bovine, very few food products derived from camel milk are available in the present market. With the advancements in food processing interventions, a wide range of dairy and non-dairy products could be obtained from camel milk, including milk powder, cheese, yogurt, ice cream, and even chocolate. In some regions, camel milk is used for traditional dishes such as fermented milk, camel milk tea, or as a base for soups and stews. Current review highlights the processing opportunities regarding the transformation of camel milk into various dairy products via decreasing the inherent functionality that could be achieved by optimization of processing conditions and alteration of chemical composition by using fortification method. Additionally, future research directions could be devised to improve the product quality.

Curcuma longa L. (CL), a traditional medicinal plant, is well known as a functional food ingredient. The major component of CL is a curcumin of anthocyanin family that has multi-functions such as antimicrobial, anticancer, and antioxidant activity. In this study, fermented milk containing CL was prepared using a mixed strain culture (Bifidobacterium bifidus, Streptococcus thermophilus, Lactobacillus acidophilus), and its physicochemical properties were characterized. In addition, inflammatory cytokine-modulating effects of the fermented milk were also investigated. As regards the properties of fermented milk, the growth rate of lactic acid bacteria in fermented milk containing CL was found to be remarkably more rapid than control. During fermentation, caseins and whey proteins were observed to be partially hydrolyzed, and lactic acid and acetic acid were produced in larger amounts than in the control. The sensory score of fermented milk containing CL was lower than control, owing to its bitter taste and strong flavor. RAW 264.7 cells treated with CL fermented milk supernatant showed no cytotoxicity. Inflammatory cytokines such as tumor necrosis factor-alpha (TNF-${\alpha}$) and interleukin-6 (IL-6) were significantly produced by fermented milk with CL, compared to control. The secretion of nitric oxide (NO) from RAW 264.7 cells significantly increased relative to the control. Results from the present study suggested that CL could be used as a natural immunomodulating ingredient for making yogurts, beverages, and other products.

In this study, traditional culture method and 16S rRNA gene analysis were applied to reveal the composition and diversity of lactic acid bacteria (LAB) of fermented cow milk, huruud and urum from Baotou and Bayannur of midwestern Inner Mongolia. Also, the quantitative results of dominant LAB species in three different types of dairy products from Baotou and Bayannur were gained by quantitative polymerase chain reaction (q-PCR) technology. Two hundred and two LAB strains isolated from sixty-six samples were identified and classified into four genera, namely Enterococcus, Lactococcus, Lactobacillus, Leuconostoc, and twenty-one species and subspecies. From these isolates, Lactococcus lactis subsp. lactis (32.18%), Lactobacillus plantarum (12.38%) and Leuconosto mesenteroides (11.39%) were considered as the dominated LAB species under the condition of cultivating in MRS and M17 medium. And the q-PCR results revealed that the number of dominant species varied from samples to samples and from region to region. This study clearly shows the composition and diversity of LAB existing in fermented cow milk, huruud and urum, which could be considered as valuable resources for LAB isolation and further probiotic selection.

Fermented milks have been recognized as healthy foods since ancient times, but those using intestinal bacteria such as Bifidobacterium and lactic acid bacteria (LAB) are even more valuable from the standpoint of view of maintaining health. They have also now come to be recognized as important in the field of preventive medicine. Although advances in the medical sciences in the last 50 years have significantly increased the human lift span, an unfortunate fact is that many of us are now living long enough to experience chronic disorders such as coronary heart disease, hypertension, osteoporosis, diabetes and cancer. In recent years there has been renewed interest in health promotion and disease prevention by incorporating probiotic bacteria into foods to counteract harmful bacteria in the intestinal tract. Therefore, there are now a wide variety of commercial products containing prospective probiotics that claim health-promoting effects, such reductions in large botvel carcinogens and mutagens, antitumor properties, cholesterol-lowering effects, increased lactose digestion, relief from con-stipation, stimulation of immunocomponent cells and enhancement of phagocytosis. Two well-known representative probiotic is LAB and Bifidobaclerium. Traditional probiotic dairy strains of LAB which have been designated as GRAS (Generally Recognized As Safe) bacteria have a long history of safe use and most strains are considered comestible microorganisms with no pathogenic potential. Accordingly, there is considerable interest in extending the range of foods containing probiotic organisms from dairy foods to infant formulas, baby foods, and pharmaceuticals. In addition, the ingestion of probiotics, prebiotics, and symbiotic as wll as combinations of pro- and prebiotics has recently aroused renewed interest as enhancing the beneficial relationship between the host and intestinal microflora in both healthy and diseased indivisuals. Non-communicable chronic diseases such as cancer, cerebral hemorrhage, is chemic heart disease, and diabetes mellitus has recently been recognized as adult diseases in Japan as well as other countries. and are considered to be inevitably associated with aging. These diseases occur as a result of individual life styles. The Japanes Government. Ministry of Health, Labor and Welfare has proposed substituting the term 'adult diseases' with 'lifestyle-related diseases'. It has emphasized the importance of prevention rather than treatment. since the well-known increase in the elderly population in Japan is predicted to result in a variety of socioeconomic problems. n this lecture on the Present status of fermented milk products in Japan, I will report a strategy for the development of fermented milk products in Japan from the standpoint of view of research in Japan on LAB and Bifidobacteria. They could play an important role in preserving human health by controlling intestinal microflora capable of producing toxic effects on the host.
