Bean sprouts have been one of the vital food for our ancestor for a long time. They were also hardy wild plants or first-aid medicine for needy people. Even nowadays they are served at table. For examples, bean curd, bean-curd dregs, bean sprouts, soybean paste, fermented soybeans, hot pepper paste, and soy are our daily food. Moreover bean sprouts are widely favored at the age of the well-being. Bean sprouts for a recover from a hangover, soybean paste for the prevention of cancer, beans leaf as the best well-being food for a diet, and so on. Thus the paper explains the origin of bean sprouts and their application as a food or medicinal stuff with the analysis of the various and wide-spread records.

This study aims to examine the consumer preference for packaged bean curd that takes a growing public interest. Specifically, this study tried to examine which is more important - the place of origin of the raw bean or the environmental-friendliness of the raw bean. Surveys were conducted to obtain information, such as the consumer evaluation for food safety on imported food products from China and the consumer perception of Chinese organic food products, Using the binary probit model, the relationship between consumer's choice of packaged bean curd and potentially important factors that can affect the consumer's choice was analyzed. A summary of this research and some policy implications follow. The results of this study can be used as the basic guideline as to how to extend the safety of imported food products, in general, and how to further develop the packaged bean curd industry in Korea, in particular.

Forty six isolates of bean common mosaic virus (BCMV) collected from azuki bean, mungbean, kidney bean, cowpea, broad bean and peanut were classified into three groups based on biological, serological, cytopathological, and molecular characteristics. Group I induced vein-banding symptoms in cowpea which was similar to those produced by the BCMV-cowpea strain. Group II caused mosaic symptoms in azuki bean but not in peanut and tobacco. Since this character was different from that of previously described BCMV strain, group II may not belong to BCMV GroupIII induced vein-clearing symptoms in azuki bean, kidney bean and peanut, which are typical symptoms for BCMV-peanut stripe virus strain. Virus inclusion patterns of BCMV groups were similar to those of Potyvirus subdivision III with the scroll, pinwheel and long laminated inclusions. However, the inclusions of laminated aggregates were never observed in mungbean isolates. Multiple alignment as well as cluster dendrograms of 3'noncoding region (3'-NCR) and a part of coat protein gene (CP) suggested that group I belongs to the BCMV-cowpea strain, group II to the BCMV-azuki bean strain, and group III to the BCMV-peanut stripe virus strain. Since molecular phylogenesis of BCMV based on nucleotides of 3'-NCR and coat protein differed from the grouping based on virulence differentiation, and BCMV groups are more closely related to each other with the same host origin, other characteristics of those strains are under investigation.

To compare chemical properties of irradiated legumes (soybean, peanut, red bean, mung bean) produced in Korea and China, radiation-induced hydrocarbons from the samples were investigated. The legumes were gamma-irradiated at 0.5, 1, 2 and 4 kGy, from which lipid was extracted with hexane. Hydrocarbons were separated by florisil column chromatography and then analyzed with GC-MS method. The chromatograms of irradiated samples showed several radiation-induced hydrocarbons, which were affected by the fatty acid compositions of legumes. Hydrocarbons, such as 1, 7, 10-hexadecatriene (16:3),6,9-heptadecadiene (17 : 2), 1, 7-hexadecadiene (16 : 2) and 8-heptadecene (17 : 1), were predominantly detected in soybean, peanut and red bean irradiated at 0.5 kGy or above, whereas 17 : 1 was not found in mung bean. The detected amount of hydrocarbons increased with irradiation doses. There is no apparent difference in qualitative and quantitative profiles of the corresponding hydrocarbons depending on the origin of legumes.

Pathological and anatomical studies on the cause of the crown gall like symptoms associated with the chestnut nurse grafts were undertaken. The crown gall bacterium, Agrobacterium tumefaciens, was isolated from the gall tissues of chestnut nurese grafts by using selective media developed by S초개소 et al. and kado and Heskett. Typical crown gall symptoms appeared on tomato, castor bean and geranium plants 10~21 days following inoculation with the bacterium isolated from the gall tissues of chestnut nurse grafts. Agrobacterium tumefaciens was reisolated from crown gall tissues of tomato, castor bean and geranium. Anatomical studies on the origin, growth and differentiation of the gall tissues of the chestnut nurse grafts confirmed that the gall tissues are of crown gall origin. Masses of Agrobacterium tumefaciens were observed from gall tissues of chestnut nurse grafts, so it could be confirmed that the crown gall symptoms prevalent on chestnut nurse grafts are caused by the crown gall bacterium, Agrobacterium tumefaciens.

Adzuki beans have gained popularity in recent years due to their health benefits. Breeding of Adzuki beans is less favorable than with other legumes due to low genetic diversity. This study aimed to evaluate the genetic diversity of 252 adzuki bean germplasms from China, Japan, and Korea using 18 agro-morphological parameters and comparing their performance to three prominent Korean cultivars: Geomguseul, Arari, and Chungjupat. Leaf shape, pod color, and seed coat color were among the qualitative traits that showed wide variations. The quantitative variables also showed wide variations among adzuki bean germplasms. Although there was no significant difference (p < 0.05), the average rate of germination declined in the order of Korean (91.44%) > Chinese (91.31%) > Japanese (87.47%) adzuki beans. Chinese adzuki beans needed fewer days to flower (DF, 58.22 days) and days to mature (DM, 107.13 days), which varied significantly compared to the Korean and Japanese adzuki beans (p < 0.05). The average number of pods per plant (PPP) and one-hundred seeds weight (HSW) were higher in Japanese adzuki beans compared to the Korean and Chinese adzuki beans although the variation of each was not significant. Almost 29.76% of the accessions had early-blooming flowers, 3.97% were premature, 21.43% produced more PPP, and 3.97% yielded more SPP compared to control cultivars. Results of hierarchical cluster and principal component analyses revealed three clusters with significant variation in all quantitative variables except for RG (p < 0.05). The key factors in multivariate analyses were DF, DM, and HSW. Our study investigated the genetic diversity of adzuki bean accessions and identified ten early maturing and ten high PPP-yielding accessions. Our findings would help farmers and breeders to select the top-performing accessions that can provide them with various options.

It has been many changes in traditional Korean food habits according to the improvement of household income levels and the rise of standard of living. Therefore, the pattern of consumption in animal origin processed/convenient foods would have changed. This research aims to find the tendency of consumption in some animal origin processed/convenient foods compared with typical Korean traditional foods according to household income levels. Therefore, this survey was made on 698 children from 10 elementary schools located in Seoul. They were divided into 6 groups according to their household income levels. The data were analysed using Chi-square test and F-test in SPSS package program. From this research, the following results were obtained: 1. Their average monthly household income levels were between 500, 000~1, 500, 000 won(64.2%) and their family were of mostly 4~5 members. There were no significant differences in children's physical status among various income groups. As the household. income level increases, the food expenditure per month increases and Engel's coefficient decreases. 2. The animal origin processed/convenient foods that have no significant differences are ham, sausage, milk, yogurt, canned fish, and fish meal. The high-income groups preferred bacon, cheese, pork cutlet, and fried chicken, compared to those of low-income groups. The low-income groups preferred crab-flavored meal, compared to those of high-income groups. 3. In some Korean traditional foods, there were significant differences according to income levels. Those were Bulgogi, baked fish, fried meat, cooked fish and meat with soy-bean sauce. Fried fish and anchovy have no significant differences in food intake frequency according to household income levels. Chicken and egg saute are liked by children in every income groups. 4. Between the animal origin processed/convenient foods and the typical Korean nonprocessed traditional foods, children preferred the former regardless of income levels. In conclusion, animal origin processed/convenient food consumption patterns were not affected by household income levels.

Quality characteristics of commercially available soybean and mung-bean flours in Korea were evaluated relative to product information such as bean content, price, chromaticity, proximate composition, water binding capacity, swelling power and solubility. Origin of raw materials was 23 in domestic products and 19 in imported products. The price of the product was 3.48 times more for raw soybean flour, 3.34 times more for fried soybean flour, and 3.47 times more for mung bean flour compared to imported soybean. In the domestic products, the lightness of raw soybean flour was higher than roasted soybean flour. The redness and yellowness of roasted soybean flour were higher than raw soybean flour. Moisture content of raw soybean flour was higher than roasted soybean flour, and crude fat, crude protein and carbohydrate content were higher in imported soybean flour. Ash and crude protein contents of mung bean were slightly higher than imported products. Water binding capacity of roasted soybean flour in domestic products was higher than raw soy flour, and there was no significant difference in solubility and swelling power. Correlation between quality characteristics of commercially available soybean and mung-bean flours products was found to be highly significant among measured items, except for solubility.

The objective of this study is to analyze the value of attributes of agricultural products in school food service using hedonic price model and choice experiment. In the case of potatoes, bean sprouts, and tomatoes, environment-friendly agricultural products rather than conventional ones, and domestic price premiums exist rather than Chungnam. The higher the price, the higher the margin rate. Conventional agricultural products were more profitable than environment-friendly ones, and domestic products were more profitable than Chungnam. In consumer preferences, environment-friendly agricultural products are preferred over conventional agricultural products and local products (Chungnam, Cheonan, Asan) rather than domestic ones. This is the opposite result of the Hedonic price model estimation that Chungnam has a lower price premium than domestic in the case of origin. This study is meaningful by analyzing the attribute value of agricultural products used for school meals in Chungnam and comparing them with the willingness to pay consumers. With the results of this study, it is necessary that discussions on supplementing the value of local products used in Chungnam school food service.
