  • The NO3 contents and organophosphorus pesticide residues in edible part of vegetables cultivated by a conventional or an organic farming methods were determined. The NO3 contents of vegetables cultivated by the organic farming method were between 120ppm and 4,523ppm, whereas its contents of vegetables cultivated by the conventional farming method were between 89ppm and 1,575ppm. Fifty two percent of vegetables cultivated by hte organic farming method accumulated NO3 content over than 2,000ppm, whereas 82% vegetables cultivated by the conventional farming method accumulated NO3 content below than 1,000ppm. The NO3 contents of lettuce dependent on the cultivation method obviously. The NO3 contents of lettuce cultivated by a hydroponic farming method were between 4,800 and 6,500ppm, whereas those cultivated by the conventional method were between 630 and 750ppm. The organophosphorus pesticide residues in edible part of vegetables cultivated by the conventional or the organic farming methods were not detected. The NO3 contents in edible part of vegetables cultivated by the organic farming method should be considered as one of several parameters to judge a real safe vegetable to be certified by goverment.

In terms of education, type of job and monthly income of respondent, the sample can be categorized as middle-class segment. The data obtained were analyzed using Structural Equation Modeling with Partial Least Square (SEM-PLS). The results of this study indicate that the information obtained by consumers significantly and positively affects consumer preferences and consumer awareness of organic vegetables. Then, consumer preferences and consumer awareness significantly and positively affect the interest of consumers to buy organic vegetables. Consumer preference for organic vegetables is still considered quite low. The factors that influence the low consumer preference are the price of organic vegetables, which is more expensive than non-organic vegetables and the unattractive packaging of organic vegetables.

  • This study investigated the effects of image on the preference and intake frequency of 19 vegetables. A total of 359 usable surveys were collected using a convenient sampling method. The subjects included females (51.8%), university students (50.7%), home residents (66.9%) and subject's spending 20,000~40,000 won on meals/week (41.5%) and eat out 2~3 times/week (29.5%). The intake frequency of vegetables was 2~3 times per month. The healthy image of all vegetables was good overall and the average preference was 3.78 (out of 5 on the Likert). Tomatoes had the healthiest image, onions the highest preference, and Korean cabbage the highest intake frequency. For males, the vegetable with the healthiest image was sesame leaf, while the healthiest foods for females were broccoli and tomatoes. Elementary students had a healthier image of cucumber, bean sprouts, radish, sesame leaf, lettuce, radish leaf, and cabbage than university students and adults. Home residents had a healthier image of cabbage and burdock than other types of residents. Subject that st over 20,000 won per week on meals had a higher image of most vegetables. In terms of preference, males liked Korean cabbage, green pumpkin, balloon flower roots, radish leaf, and lotus root, but female liked tomatoes. In addition, elementary students, home residents, and subjects who eat out less often tended to prefer vegetables. In terms of intake, there was a high frequency of intake for all vegetables in adults. Home residents specifically had a higher intake of cucumber, carrot, bean sprouts, spinach, green pumpkin, balloon flower roots, lettuce, radish leaf, broccoli, burdock, lotus root, and tomato. Overall, the healthy image of vegetables had a positive influence on their preference and intake frequency. Therefore, to encourage the intake of vegetables, direct or indirect variables should be examined.

  • The effects of dietary buckwheat vegetables on the in vitro HMG-CoA reductase activity and lipids profiles of serum and liver in rats were evaluated . Buckwheat vegetables were cultivated in the range of 1-15cm of the plant height and dried. The content of rutin in the dried vegetables did not varied largely with the differences in the height of the vegetables. The water extract from buckwheat vegetables activited in vitro HMG-CoA reductase, activity up to 150% of control. Male rats were fed on purified diets. supplemented with0.12% cholesterol, containing dried buckwheat vegetables(BWV, 5% of diet) or rutin 90.25% of diet) . Dietary BWV and rutin, compared with basal diet tended to decrease the concentration of serum cholesterol. The ratio of HDL-cholesterol to total cholesterol were higher slightly in the rutin -fed group than in the other groups. The concentration of serum triacylglycerol was lower markedly in the rutin -fed groups than in the control groups, and BWV group being intermediate . The concentration of liver cholesterol was lower significantly in the BWV group than in the other groups. The results show an effective cholesterol-lowering action of buckwheat vegetables in serum and liver of rats fed on cholesterolemic diets. and that the hypocholesterolemic effects of buchwheat vegetables re not likely to be due to the modulation of the cholesterol synthesis rate.

  • Children's exposure to various vegetables has been associated with higher preferences and intake of vegetables. Attractive names have been reported to increase children's vegetable intake in school lunches. This study hypothesized that the number of vegetables identified correctly may be used as a measure of exposure to vegetables. The survey was administered to students (n=368) at an elementary school located in Gyeonggi-do to determine the association of number of vegetables identified correctly with factors regarding vegetable intakes and effects of descriptive menu names on consumption intentions in school lunches. Students were asked to identify the correct names for nine vegetables and rate their desire to eat six vegetable dishes labeled with general names and two different descriptive names. Descriptive menu names did not consistently increase subjects' desire to eat vegetables compared to general menu labels. Children who ate two vegetable dishes and more per meal tended to identify the names of more vegetables than those who ate less, without reaching statistical significance (P=0.057). Moreover, 5th graders who answered that they ate more than two vegetable dishes each meal had significantly higher scores in identifying vegetable names than those who did rarely (P<0.05). There was no significant association between the number of correctly identified vegetable names and children's vegetable preferences and frequency of being served vegetable dishes. Mother's vegetable preference showed a significant positive association with vegetable preferences of children (r=0.147, P<0.01) and fathers (r=0.340, P<0.01) as well as the number of correctly identified vegetables by children (r=0.183, P<0.01). The results of this study cannot support the advantage of descriptive menu labels over general menu labels. However, it suggests that the number of correctly identified vegetable names could serve as a measure of children's exposure to vegetables associated with factors regarding vegetable intake.

  • 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.

  • This paper is intended to study what kinds of the vegetables are mentioned in the Bible and how they were used in those days. While one hundred and twenty-eight different plants are mentioned in the Bible, there are today 2,384 plant species in modem Israel, most of which have been introduced in recent centuries. These plants obviously did not exist there in biblical times and were only recently introduced from Australia and South America, respectively. This article will study only the vegetables mentioned in the Bible and known to have existed in the old and new testament times. Since the first book devoted exclusively to biblical botany was that of Levinus Lemmens in 1566, the modem systematic study of biblical plants, began with F. Hasselquist, a student of Linnaeus, the founder of modem botany. In 1928, Immanuel Loew approached the subject differently, reviewing all known data pertaining to biblical plants. His work not only discussed biblical plants, but also plants in later Jewish literature, particularly the Talmud. The British scholar G. E. Post provided a broad field study of modem plants in Palestine, Syria, Lebanon, and Jordan. More recent major treatments of the subject include those of A. and H. Moldenke (1952), M. Zohary (1982), N. Hareuveni (1984), and Y. J. Choi(1996). Today, articles on specific biblical plants listed in the Bible can be found in any number of encyclopedias. This study attempts to provide a synthesis of the work of a number of scholars who studied the vegetables and plants mentioned in the Bible. As a preliminary study on the culture of food in the biblical period, this study has focused on the identity and features of the vegetables of the Bible. In only a limited number of instances, because of the paucity of the informations and the broad and generic descriptions of the plants, we can't be certain about the identification of the vegetables named in the Bible. In many instances the traditions established by the Greek, Aramaic, and English translations are helpful, although sometimes they are misleading. This paper subdivides the vegetables into broad areas, the general vegetables and the flavoring herbs. Vegetables formed very important part of the diet in the biblical times. Two main types were used: those whose nutritious seeds could be easily stored and those which were eaten freshly gathered from gardens. Pulse seeds provided a useful source of vegetable protein, while fresh green vegetables were vitamin rich. Pulses could be eaten boiled, or their dried seeds could be ground up into flour and then made into nutritious soups. Fresh vegetables were eaten either raw or lightly cooked, usually by boiling in water. The general vegetables in the Bible are herbs(garden rocket), cucumber(snake cucumber), watermelon, leeks, chicory, and onions. Also the flavoring herbs in the Bible are rue, dill, cummin, black cummin, frankincense, cinnamon, cassia, myrrh, black mustard, coriander, mint, saffron, ginger grass, syrian hyssop, aloes(eagle wood), manna which have the flavor, aroma, and medical values.
