Noodle was made using a combination of yulmu, wheat and water through mixture design. Statistical models of yulmu noodle were shown by analysing tensile stress and color $(L^{*})$, and sensory evaluation with other constraints. Analysing the linear and non-linear model, the linearity in the values of tensile stress, lightness $(L^{*})$ and sensory evaluation showed that each component worked separately without interactions. In studying the component effect on the response by trace plot, the result indicated that the increase in the amount of yulmu enhanced tensile stress of noodle while degrading $L^{*}$ value and sensory evaluation score. In the range of satisfying the conditions of noodle in every tensile stress, $L^{*}$ value and sensory evaluation point, the optimum mixture ratio of yulmu : wheat : water was 2.27% : 66.28% : 28.45% based on least cost linear programming. In this calculation, the least cost was 9.924 and estimated potential results of the response for tensile stress was 2.234 N and those for $L^{*}$ was 82.39. Finally, the potential response results affected by mixture ratio of yulmu, wheat and water were screened using Excel.

This study was conducted to investigate the actual conditions of intake of Korean traditional beverages in 273 female university students in Seoul, Korea. The subjects of this study consisted of 128 food and nutrition majors and 145 non-majors. Questionnaires were administered to the subjects who had an average age of 20 years. Two-hundred and nineteen students (80.2%) lived with their parents. Regarding the type of beverages subjects often drink, coffee was the most preferred (51.3%) overall, and non-majors (4.1%) were shown to drink traditional beverages more often. Regarding preference for traditional beverages, most subjects (72.5%) responded that they liked their own traditional beverage. However, for frequency of intake of traditional beverages, 48.7% answered they do not drink any traditional beverages. The reasons why subjects like traditional beverages were taste (71.7%) and health (26.3%), and the type of traditional beverages they often drink were Yulmu tea (35.9%), Sik hae (30.8%), and Yuja tea (10.6%), in order. Regardless of major, ginseng tea, jujube tea, mulberry-leaf tea, Chinese matrimony vine tea, ssanghwa tea, ginger tea, and omija tea were found to be satisfactory traditional beverages. Therefore, due to the low intake frequency, preference, and satisfaction of traditional beverages, new traditional beverages that can meet the standards of female students should be immediately developed.

In obesity, adipocytes undergo abnormal growth characterized by increased cell numbers and differentiation. Thus, inhibition of mitogenesis of preadipocytes and their differentiation to adipocytes would be beneficial for the prevention and progression of obesity. In the present study, we attempted to evaluate antiadipogenic activity of adlay (Coix seed, the seed of Coix lacryma-jobi L. var. ma-yuen Stapf) employing preadipocytes cell line, 3T3-L1 as an in vitro assay system. Because several varieties of adlay are in use in Korea, anti-adipogenic activity of three varieties of adlay such as Sang-Gang, Jo-Hyun and Yulmu-Ilho was evaluated. All the three varieties of adlay showed significant inhibitory activity on adipocyte differentiation as assessed by measuring fat accumulation using Oil Red O staining. Adlay, however, showed little effects on adipocyte proliferation. Further studies with interval treatment demonstrated that adlay exerted inhibitory activity on adipocyte differentiation via acting on early stage of adipogenesis. Taken together, adlay might be useful in the prevention of obesity.

This study was conducted to investigate the standardization of kimchi and related products. There are about 339 kinds of kimchi and related products in Korea. Half of those various kimchi was 50% of the total products, and the other groups are in the order of Jangachi (high salted vegetable pickles, Saengchae (a salad type kimchi), Kakduki(reddish kimchi), Keotjulyi(nonfemented kimchi), Pickles, Seobakji (kimchi based on raddish, fish and other ingredients) and Shickgae (lactic fermented fish products). About 200 ingredients (chinese cabbage, raddish, cucumber, other vegetables, fruits, seaweeds, fish, meat etc.) were used for those products. Tongbaechu kimchi (whole headded chinese cabbage kimchi) and Possam kimchi (wraped kimchi with chinese cabbage leaves) were made by about 30 ingredients, respectively. Kakduki, Oyster-kakduki, Chonkak kimchi (kimchi based on small raddish with leaves) and Tongchimi (raddish kimchi with brine soup) were made by raddish and more than 10 ingredients, but the subsidiary ingerdients were less than that of chinese cabbage kimchi. Other products such as Yulmu kimchi and Oisobaki (a cucmber kimchi) were also dicussed.

This study was conducted to (a) investigate the frequency of Korean beverage consumption, (b) analyze the characteristics of socio-demographically classified group according to drinking frequency, (c) investigate the attitude for and awareness of Korean beverage and (d) analyze the factors which influence Korean beverage consumption. The survey was carried out by self-administered questionnaires with 2,200 subjects residing in Seoul. A total of 1,885 samples were used for analysis by using t-test, one way analysis of variance (ANOVA), Duncan's multiple comparison test, factor analysis, and analysis of covariance (ANOCOVA) with SAS computer program. Among various Korean beverage, Donggulre tea was consumed most frequently at an average of 7.4 times per month, and followed by rice beverage, Mi Su, Citron tea, Shick Hae and canned Shick Hae. Among the age groups, the group of 20s showed the lowest frequency of Korean beverage consumption exempt rice beverage. According to occupation group, middle and high school and college student groups showed a high frequency of consumption of cereal based drink such as rice beverage, Mi Su and Yulmu tea. The behavior examination aimed at learning the perceptions relevant to the choice of beverage showed that the subjects believe Korean beverage healthful and nutritious but not familiar through advertisement, not easy to buy, and not to be a habitual drink. The factors influencing the frequency of Korean beverage consumption were shown as health-related factors and habitual/practical factors.

This study was carried out to isolate the colonies of dominant fermented bacteria from Kimchi (Korean native fermented foodstuffs) and investigate their inhibitory potentials on mutagenesis and carcinogenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) as direct carcinogen. For this purpose, single cell gel electrophoresis technique (SCGE assay, or comet assay) which is a sensitive and rapid technique for detecting the presence of DNA strand breaks in individual cells was used. DNA damages of Kimchi isolates were compared with that of the positive control, MNNG. Among 3 isolates from Tongbaechu Kimchi, two isolates B-1 and B-2 showed antigenotoxicities (p<0.01). All 4 isolates from Yulmu Kimchi had antigenotoxicities (p<0.05). Also, 3 of 5 isolates from Chonggak Kimchi and 2 of 9 isolates from Kaktugi were antigenotoxic (p<0.05 and p<0.01, respectively).
