  • About 760 papers and patents of the traditional fermented food in Korea were collected which were published during 1917-1988, and then the papers were classified, outlined and reviewed. Study of traditional fermented food was about 10% of total study on Korean Foods, and that of alcoholic beverage was 50%, soy sauce and related product was 30% and kimchi was less than 20% of total study of traditional fermented foods. Though considerable amount of studies were accomplished before the World War II, but a few study was accomplished during the Korean war. The research activity is, hitherto, increasing gradually, but the systematic studies were rarely done. The studies to be investigated were processing quality of raw materials, classification, standardization, sensory quality of the product and so on.

  • The purpose of this study was to investigate pattern of consumption of Korean fermented foods. The questionnaires have been collected from 290 housewives in Taejon. Kimchi was the most frequently selected for meal preparation among Korean fermented foods. Ninety seven percentage of housewives used Kimchi over once a day and 87%, every meal. Chin-ganjang, Kuk-ganjang, Kochujang and Doenjang have been consumed over once a day by 47%, 46%, 31% and 27% of housewives respectively, which indicated that those jangs were still essential seasonings for preperation of Korean foods. The percentage of housewives, who did not use Chonggukjang, Jot-kal and Jangatchi, were 18%, 19% and 22% respectively, With the educational level increasing and age decreasing, the frequency of consumption Kimchi, Jangat-chi, Doenjang, Kochujang, Jot-kal and Chonggukjang became lower. Extended family often used Doenjang more than nuclear family. Working housewives utilized more Jot-kal than full time housewives. Seventy four percentage of housewives replied that the consumption of Korean fermented foods came to reduce. The reasons were that the kinds of foods increased(54%), food preference of children was changed (27%), side dishes were increased(10%), and food preference of adults was changed(9%). Kimchi has been made by housewives themselves(86%) and by relatives(11%). It means that most housewives prefer home-made Kimchi. Half of housewives used jangs made by themselves. The younger and the higher in educational level use the less Hey have made of Kimchi and jangs.

  • The authur surveyed the caries experience of 108 preschool children and collected their five-day dietary data, and evaluated the cariogenicity applied to their diets and discussed the relationship between their caries experience and their diet. The results were as follows: 1. As a frequency of consumption of cariogenic foods by degree of retentiveness, highly retentive foods like sugars and dried fruits had been taken once every 3 days, next highly retentive foods like confections and breads had been taken once everyday, slightly retentive foods like ice-creams and fermented milk also had been taken once everyday, and low retentive foods like soft drinks had been taken once every 6 days. 2. The highest caries experienced children ingested more frequently retentive foods like ice-creams, fermented milk and sugars than the lowest caries experienced children. 3. As a potential cariogenicity, the mean number of cariogenic ingestions in a day was 2.26, the mean retentiveness in a day was 5.93, and the mean cariogenicity score per ingestion in a day was 2.51. 4. The highest caries experienced children had higher values in the mean cariogenic ingestions, the mean retentiveness, and the mean cariogenicity score than the lowest caries experienced children.

  • Soybean has been favored by many Thai people and it has been prepared by numerous different methods. Collected samples are as follows: Thua-nao paste from Chiangrai province, dried Thua-nao for Jatujak Market, Bangkok, 3 types of commercial soybean paste, soybean sauce and 2 types of fermented soybean curd cakes with other ingredients. Moisture contents of fresh and dried Thua-nao were 68.5 and $7.6\%$, respectively; therefore the shelf-life of dried Thua-nao can be extended to 1 year with proper packaging. The remainder of the soy foods had moisture contents of 55.4 to $64.4\%$. Fat contents of fresh and dried Thua-nao were 7.4 and $19.7\%$, respectively, whereas other samples contained less than $3\%$. Dried Thua-nao had the highest CHO (carbohydrates) content $(37.4\%);$ in contrast, soybean sauce contained only $4.5\%$. Calcium content was highest in dried Thua-nao followed by fresh Thua-nao; the other fermented soy foods had less than 44.7 mg/l00 g. Salt was added to samples other than Thua-nao resulting in high Na contents. Free and total daidzein contents of dried Thua-nao were 355 and 676 ug/g; similarly free and total genistein contents were 293 and $616.5\;\mug/g$, respectively.

  • This study examined the food culture of the Koryo Dynasty during the early 13th century based on the records of wooden tablets and marine relics from the 1st and 2nd ships of Mado wrecked at sea off Taean while sailing for Gaegyeong containing various types of grain paid as taxes and tributes. The recipients of the cargo on the 1st ship of Mado were bureaucrats living in Gaegyeong during the period of the military regime of the Koryo Dynasty, and the place of embarkation was the inlet around Haenam (Juksan Prefecture) and Naju (Hoijin Prefecture) in Jolla-do. On wooden tablets were recorded 37 items of rice, cereal, and fermented foods. The measures used in the records were seok [石-20 du (斗)] for cereal, seok [15 du, 20 du] for fermented soybean paste, and pot (缸) and volume (斗) for salted fish. The places of embarkation on the 2nd ship of Mado were Jeongeup (Gobu Prefecture), Gochang (Jangsa Prefecture, Musong Prefecture), etc. On wooden tablets were recorded 29 items of rice, cereal, fermented foods, seasame oil, and honey. The volume measure for yeast guk (麴), the fermentative organism for rice wine, was nang [囊-geun (斤)], and the measure for sesame oil and honey, which were materials of oil-and-honey pastries and confections, was joon (樽-seong, 盛). Honey and sesame oil were luxury foods for the upper-class people of the Koryo Dynasty, and they were carried in high-quality inlaid celadon vases in Meibyung style. Food names and measures written on wooden tablets and actual artifacts found in the 1st and 2nd ships of Mado are valuable materials for research into agriculture, cereal, and fermented foods of the Koryo Dynasty in the early 13th century. Besides, relics such as grains and bones of fish and animals from the Koryo Dynasty are expected to provide crucial information usable in studies on food history of the Korean Peninsula.

  • Food choice is influenced by many factors including physical, social, psychological and food technological developments. This research is based on the survey on Puchon housewives dietary culture according to season and special occasions and the current consumption pattern of traditional fermented foods. The objective is to find out the current consumption and to use this data as the principal element needed to explore changes in consumption patterns and to uphold and develop the consumption of traditional fermented food. Questionnaires were collected 282 housewives in Puchon city. Data were analysed with SAS software package for t-test, F-test and Duncan’s multiple range test. Results of relationship between dietary culture of Puchon housewives and consumption patterns of traditional fermented food items; 1. If we look at seasonal foods, Puchon housewives responded that they normally prepare traditional foods for such special occasions as Chusok(89%), New Year(84%) and January full moon Day(77%). For family celebrations, they cook on their in-laws birthdays(91%), their husbands birthday(84%), childrens birthdays(73%) and their own birthday(32%). They also responded that they eat out on their own birthday(41%), on Christmas Day(19%), on childrens birthdays(17%) and on their husbands birthday(11%). 2. If we look at the age of housewives and their dietary culture, more young housewives tend to eat out on their own, their husbands and their childrens birthdays. As for their educational background, less educated housewives tend to prepare flood at home on New Years Day, while more educated housewives would eat out on their own birthdays. As for the type of family, mere housewives in nucleus families eat out on Christmas Days compared to those in extended families. Also, those in extended families tend to make food at home rather than eating out on their own birthdays. In case of the husbands birthday, there was some difference according to family income (p<0.03).

  • Doenjang (Korean fermented soybean paste) is one of important fermented foods in Korea. Doenjang has been traditionally manufactured from meju which is fermented rectangular shape of crushed cooked soybeans. The main microorganisms involved for meju fermentation are Bacillus subtilis and molds such as Rizopus sp., Mucor sp. and Aspergillus sp. We have already reported that Doenjang is free from mycotoxin, especially, aflatoxin B$_1$contamination during the manufacturing process of the Deonjang.(omitted)

  • Lactic acid bacteria (LAB) fermented foods were prepared from egg white powder (EWP), casein and growth stimulating agents (GSA). The effects of GSA on acid production and growth of Lactobacillus were studied. The effects of GSA on sensory properties and viscosity of LAB fermented foods were also studied. Acid production by Lactobacillus was stimulated by addition of GSA (0.3% or 1%, W/V). Although stimulating effect differed among each GSA, some GSA increased the acidity up to the level of fermented milk. However, stimulating effect of GSA on viable cells was not noticeable. Acid production by L. acidophilus was generally higher than other Lactobacilli. The optimum concentration of GSA added to substrate was 1% (W/V). Sensory evaluation showed that the optimum fermentation time was 18hr. The sensory properties of GSA samples were evaluated as slightly lower than that of fermented milk because GSA samples showed whey separation and taste and smell of GSA. Apparent viscosity of GSA samples was significantly lower than that of fermented milk and control sample (p<0.05). There was no significant difference of apparent viscosity among GSA samples. GSA samples, fermented milk and control sample showed thixotropic flow characteristics.

  • Asian populations are thought to receive significant health benefits from traditional diets rich in soybeans due to high isoflavone contents. However, available epidemiologic data only weakly support this hypothesis. The present study was carried out to assess the pharmacokinetics of isoflavones in South Korean women after ingestion of soy-based foods. Twenty-six healthy female volunteers (20-30 y old) consumed three different soy products (i.e., isogen, soymilk, and fermented soybeans) with different aglycone/glucoside ratios. Plasma and urine isoflavone concentrations were measured by high-performance liquid chromatography (HPLC) after ingestion of one of the soy products. Pharmacokinetic parameters were determined using the WinNonlin program. The area under the curve (AUC) for plasma daidzein levels of the soymilk group ($2,101{\pm}352ng{\cdot}h/mL$) was significantly smaller than those of the isogen ($2,628{\pm}573ng{\cdot}h/mL$) and fermented soybean ($2,593{\pm}465ng{\cdot}h/mL$) groups. The maximum plasma concentration ($C_{max}$) of daidzein for the soymilk group ($231{\pm}44$ ng/mL) was significantly higher than those of the isogen ($160{\pm}32$ ng/mL) and fermented soybean ($195{\pm}35$ ng/mL) groups. The half-lives of daidzein and genistein in the soymilk group (5.9 and 5.6 h, respectively) were significantly shorter than those in the individuals given isogen (9.6 and 8.5 h, respectively) or fermented soybean (9.5 and 8.2 h, respectively). The urinary recovery rates of daidzein and genistein were 42% and 17% for the isogen group, 46% and 23% for the fermented soybean group, and 33% and 22% for the soymilk group. In conclusion, our data indicated that soy products containing high levels of isoflavone aglycone are more effective for maintaining plasma isoflavone concentrations. Additional dose-response, durational, and interventional studies are required to evaluate the ability of soy-based foods to increase the bioavailability of isoflavones that positively affect human health.
