  • The author examined the origins, the course and the period of introduction of 94 types of vegetables and fruits mainly used in Korea. Then, based on it, the author looks into the relationship between food culture in Korea and those in the Silk Road. Among the vegetables and fruits, 57 types are not originated from Korea 17 types of stem and leaf vegetables, 9 types of root and fruit vegetables. 7 types of fruits, 6 types of seed, 6 types of pomes, 2 types of berries and grapes, and 1 type of nut. Their origins are spread in Europe, Southwest and South Asia but interestingly, they are located near or along the Silk Road. Therefore, it can be presumed that the vegetables and fruits were introduced into Korea from its neighboring countries by way of the Silk Road even before the Three Koreas Period and they were eaten widely in the Joseon Dynasty. Thus, the Silk Road helped some of the vegetables and fruits used in Korea to be introduced into Korea and eventually, contributed to diversifying Korean food culture. The cultural exchange is not one-way but two-way communication and the cultural exchange through the Silk Road is no exception. It is certain that by way of the Silk Road, foods and recipes were introduced into Korea from other countries but at the same time, Korean foods and recipes were propagated to other countries. In the future, more researches and studies should be conducted to find out how the foods and recipes are exchanged among the countries by the way of the Silk Road.

  • This study was conducted to survey multiple factors of aversion to vegetables and preferences for vegetable-related recipes in school meal services among elementary school children in order to help develop various menus and recipes for school meal services. Questionnaire survey was carried out with the study subjects, who were 401 children in 6th grade attending elementary schools in Chonnam and Kwangju metropolitan regions. Results from the survey can be summarized as follows: 65.1% of respondents answered they try to eat vegetables and other namul side dishes served in school meal service for health. As for the frequency of taking vegetables and namul side dishes out of daily meals, 47.4% of respondents chose 'once or twice'. The reasons for aversion to vegetables in boys were taste and cooking method, while girls were taste and feeling between teeth. In boys there were no differences between regions of Kwangju and Chonnam but the tendency of aversion to vegetables was significantly high in girls. As for the aspects of vegetable aversion of subjects, 46.9% of respondents took up 'black & purple' in the unfavorable color of vegetables. 49.1% in 'bitterness' and 39.2% in 'greasiness' were in terms of the aversive taste of vegetables. The aversive vegetable recipes were 58.6% in 'raw & seasoned' and the unfavorable feeling of vegetables were 53.1% in 'squashiness'. There were differences between regions of Kwangju and Chonnam with boys in color and cooking method in girls. Results from the survey on their preferences for vegetable recipes showed that leafy vegetables like crown daisy (raw/slightly seasoned) and pak choi (broth/pot stew) fell to the most aversive category, while bean sprouts (broth/pot stew) were chosen as the most favorable one. Among root vegetables bell-flowers were found to belong to the least preferred recipe, while potatoes were proven to be most preferable in terms of recipes. As for fruit vegetables and other vegetables, all respondents didn't like 'fatsia shoots' vegetable and it's cooking method and they preferred 'green pumpkins (broth/pot stew)'. In respect of mushrooms, enoki mushroom (broth/pot stew) was found most preferred and had high tendency of preferences in boys and girls in Kwangju compared with Chonnam region. The study results indicated that respondents did not show big differences in factors influencing them to be averse to vegetables and their preferences for vegetable recipes depending on regions. In order to have high preference and intake in children's diets, it needs to study in reform of menu about using namul or vegetables mixed with meats and fruits that children preferred or applying roasted and fried other less than namul.

  • After the release of facts that the high nitrate contents in vegetables by Korean organic farming, organic farmers were recommended by Korean Organic Farmer Association to apply 20t/ha compost while they applied before as much as they could, sometimes even more than 100t/ha. This study was aimed to check the safety of Korean organic product in terms of nitrate content. Current nitrate content in leaf and root vegetables by 3 different farming systems(organic farming, conventional farming, greenhouse farming) were monitored and furthermore it was compared with previously published another data in Korea to find out any changes among the monitored years(1993-1999). Current nitrate content in chinese cabbage, lettuce and kale became less compare to those of the beginning of monitoring, and especially those cultivated organic farming got the lowest value while previous organic vegetables at beginning of 90's showed the higher value than those cultivated in greenhouse. This decrease in organic vegetables was affected by less application rate of organic fertilizer than before at 20t/ha. But the nitrate level by organic farming was still higher compare to those cultivated by conventional farming in open field, since currently monitored organic vegetables were cultivated basically in greenhouse condition. It shows the organic farmer the necessity of transfer their farming site and condition from greenhouse to open field in order to decrease of its high level of nitrate caused long-term application and slow release characteristics of organic fertilizer. It was concluded the adoption of soil nitrate test to recommend a organic farmer the exact application rate for need of crop growth. Additionally the mechanism of lower nitrate accumulation in rice and fruit vegetables were also discussed in the paper.

  • Objectives: Vegetables are the most left over side dishes in school lunch programs. This study intended to analyze the differences in preference for vegetables among the students of different age groups in order to determine potential ways of increasing vegetable consumption in this study group. Methods: A total of 308 primary to university students in Gyeongbuk area were recruited and a questionnaire-based survey was conducted. The preference score (7-Likert scale: very much dislike (1)~so-so (4)~like very much (7)) and intake frequency (5-Likert scale) of 48 kinds of vegetables in 4 vegetable groups, such as vegetable (fruit-, root-, leaf-, and stalk-vegetable), seaweeds, mushrooms, and kimchi were investigated, and data were analyzed by SPSS WIN (ver 12.0). Results: The preference scores of vegetables except for seaweeds were significantly different among school groups, university was the highest, followed by high school. Primary and middle school students showed the lowest preference score, especially for leaf- and stalk- vegetables. The preference score for seaweeds was the highest of 5.28, followed by kimchi of 4.99. With regard to kimchis, the preference score was the highest in university', followed by high school, middle school, and primary school' was the lowest. The number of vegetables with < 4.0 preference score was the highest in primary school of 16, 15 in middle school, 11 in high school, and 7, the lowest in university. The vegetable with preference score of < 4.0 in all 4 school groups were mallow, chard, bud, radish leaf, mugwort, butterbur and sweet potato stalk. With regard to the intake frequency of vegetables, kimchis, an indispensable part of the Korean diet, was the highest of 2 times/day, followed by cooked vegetables of 1.5 times/day. The correlation coefficients between preference scores and intake frequencies were statistically significant in all groups of vegetables. As for the coefficient of variation (CV) of preference score, primary school' was the highest and university' was the lowest. The number of vegetables with high CV and high inexperience were highest in primary school students. Conclusions: Providing more opportunities for consuming a variety of vegetables, such as leaf- and stalk-vegetable, it may be possible to increase vegetable consumption, especially for the primary school students.

  • Purpose: We have studied the necessary qualities of seedlings of some leafy vegetables for a riding-type two-row automatic transplanter. When seedlings are planted using a transplanter, long roots may be rounded in the bottom of the tray, and this can interfere with the separation of the seedlings. Uprightness related to leaf spread angle is an important quality for seedlings in mechanical planting. Methods: To select cultivars suitable for the transplanter, we compared varieties of Kimchi cabbage (Chukwang, Daetong, Whipalam and Namdo), head lettuce (Abi and Sensation), cabbage (YR Onnuri, YR Hogel, Harutama, and Ogane), and broccoli (Nicegreen and Earlyyou). To compare the effect of bed soil on root formation and growth, we used five types of soil: Chologi, Burger, Wonjomix, Bio, and Baroker with 2.6-3 L per tray. Growth increment and the degree of root formation were measured according to the RDA guidelines 25 days after sowing for Kimchi cabbage and head lettuce and 44 days after sowing for cabbage and broccoli. Conclusions: According to the plug tray, the optimum seedling age in both 128- and 200-hole trays was 28 days for Kimchi cabbage and 44 days for cabbage and broccoli. Head lettuce took 35 days in 128-hole trays and 31 days in 200-hole trays. Burger soil was most effective for root formation and growth of the four kinds of leafy vegetables; it appeared that smaller soil volume led to faster root formation.
