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.

This study was conducted to investigate the attitude to various soy foods and to estimate dietary isoflavone intake among Korean adolescents. The survey was carried out by self-administered questionnaire with 800 middle and high school students residing in urban and rural areas and 714 questionnaires were collected: resulting in 89% response rate. The dietary isoflavone intake was estimated by food frequency questionnaire developed for rapid assessment of isoflavone intake. Soybean paste, soybean curd, soy milk, bean sprouts and dambuk were recognized as nutritious and healthy food in order. Dambuk got the lowest score in taste and flavor. Bean sprouts, soybean curd and soybean paste were recognized as familiar food in order. Stuffed rice in fried soybean curd got the highest score and Miso soup got the lowest in preference. More than 50% of the subjects consumed soybean paste stew/soup and soybean curd over twice per week and 12.3% of the subjects consumed soybean over once a day. The estimated daily intake of isoflavones ranged from 0 to 227 mg, and the mean daily isoflavone intake of the subjects was 28.1 mg (16.3 mg genistein and 12.0 mg daidzein) whereas the median value of isoflavone intake was 19.7 mg. There was statistically significant relationship among Kyung Gi Do, Chung cheung Do and Seoul residents in their intake of isoflavone. The highest monthly income group consumed isoflavone more than the other groups. These results suggest that Korean adolescent perceived the soybean dishes as high quality foods but they didn't take much because of difficulty to cook or less chance to eat. Nutrition education program is needed to enhance consuming soy foods for prevention of chronic diseases related to dietary isoflavone intake. More detailed information on easy cook method of soy food is also needed.

BACKGROUND/OBJECTIVES: The glycemic index (GI) is a measure of the postprandial glucose response (PPGR) to food items, and glycemic load (GL) is a measure of the PPGR to the diet. For those who need to maintain a healthy diet, it is beneficial to regulate appropriate levels of blood glucose. In reality, what influences the meal GI or GL depends on the macronutrient composition and the physical chemistry reactions in vivo. Thus, we investigated whether different macronutrients in a meal significantly affect the PPGR and the validity of calculated GI and GL values for mixed meals. SUBJECTS/METHODS: 12 healthy subjects (6 male, 6 female) were recruited at a campus setting, and subjects consumed a total of 6 test meals one by one, each morning between 8:00 and 8:30 am after 12 h of fasting. PPGR was measured after each consumed meal and serial finger pricks were performed at indicated times. Test meals included 1) 68 g oral glucose, 2) 210 g rice, 3) rice plus 170 g egg white (RE), 4) rice plus 200 g bean sprouts (RS), 5) rice plus 10 g oil (RO), and 6) rice plus, egg white, bean sprouts, and oil (RESO). The incremental area under the curve (iAUC) was calculated to assess the PPGR. Mixed meal GI and GL values were calculated based on the nutrients the subjects consumed in each of the test meals. RESULTS: The iAUC for all meals containing two macronutrients (RS, RO, or RE) were not significantly different from the rice iAUC, whereas, the RESO iAUC ($2,237.5{\pm}264.9$) was significantly lower (P < 0.05). The RESO meal's calculated GI and GL values were different from the actual GI and GL values measured from the study subjects (P < 0.05). CONCLUSIONS: The mixed meal containing three macronutrients (RESO) decreased the PPGR in healthy individuals, leading to significantly lower actual GI and GL values than those derived by nutrient-based calculations. Thus, consuming various macronutrient containing meals is beneficial in regulating PPGR.

식용 감미료 아스파탐은 아미노산 중 하나인 아스파라긴과 페닐알라닌의 합성으로 형성된 것이다. 자당보다 200배 높은 단맛을 내는 단백질 성분으로 당 대체할 수 있는 물질이기에 다이어트 제품으로 사용된다. 동물과 인체에 끼치는 영향에 관한 연구는 잘 되어있지만, 식물 대사에 관한 연구는 된 적이 없다. 본 연구에서 발아된 양파, 콩나물, 칼란코에를 재료로 아스파탐 물질대사 영향을 실험하였다. 발아된 뿌리를 가진 3종류 식물은 1mM 아스파탐을 처리한 초기에는 급속히 성장하는 효과를 나타내어 구성 성분인 아미노산 영향으로 영양분 공급 효과를 보인다. 하지만 4주 동안 처리될 때 측근과 유사한 돌기 증상이 양파에서 목질화된 형태로 나타나고, 빨리 시들은 효과가 콩나물에서 보이며, 뿌리의 노화현상이 12주 된 칼란코에에서 나타난다, 모두 성장 단계를 지나서는 노화 촉진 현상을 보인다. 이것은 구성 성분인 두 종류 아미노산 중에 아스파라긴은 급성장을 유도하는 옥신 발생과 관계가 있다고 보여 주고, 페닐알라닌 효과로 목질화 현상이 나타나는 결과로 생각하여진다.

Four dietary fiber enriched menus for the aged were developed and physicochemical were analyzed. Major foods enriching the dietary fiber were as following; kimchi & bean sprouts soup and sweet potato for menu 1, chamcheunamul and grape for menu 2, mushroom and kimchi for menu 3, dried radish leaves and green pepper for menu 4. One portion of calorie, carbohydrate, protein and fats for the aged were calculated as 567 kcal, 92.8 g, 21.3 g and 12.6 g, respectively based on recommended daily allowances for adults. Dietary fiber content increased in the menus 1, 2, 3 and 4 were 17.27%, 20.84%, 16.91%, and 23.64%, respectively. The menu 1 had significantly the highest acceptance scores among the rice, soups, side dishes and overall desirability with the acceptance sores of 4.77, 4.58, 4.62 and 4.69, respectively(p<0.05). Female showed significantly the higher acceptance scores of all of the enriched fiber menu than those of male. Moisture contents of the boiled rice with barely in menu 3 had significantly the highest value of all(p<0.05) and the side dishes of all menus did not show any significant differences at p<0.05. The pH value of boiled rice with barely in menu 3 was significantly the highest and menu 1 of kimchi & bean sprouts soup had significantly the lowest pH values(p<0.05). Hunter L value was significantly the highest in boiled rice with barley. The dietary fiber enriched menus were successfully developed for application and standardization in the meal service planning for the aged as one of trials of basic data collection.

본 연구에서는 선행연구에서 우량 콩나물로 선별된 이소 플라본을 다량 함유한 콩나물의 투여가 실험적으로 유발된 고지혈증 흰쥐의 지질대사에 미치는 효과를 조사하였다. 고지혈증은 SD계 흰쥐에 cholesterol 0.5%, lard 9.3%, sodium cholate 0.2%를 함유한 AIN standard식이에 의해 유발되었다. 실험군은 정상 대조군, 고지혈증 대조군, 고지혈증 유발식이에 1%, 5% 콩나물 분말, 또는 0.2% 대두 이소플라본 추출물 보충군으로 하였다. 실험식을 4주간 투여한 후 혈장 지질과 과산화물 수준, 간조직의 항산화효소 활성도, 혈장 항산화 영양소 수준을 측정하여 다음과 같은 결과를 얻었다. 콩나물 분말의 보충 투여는 고지혈증 동물의 식이효율$(0.33{\sim}0.34)$에 영향을 미치지 않았으며 고지혈증 쥐에서 혈장 중성지질의 저하 경향을 보였으며 총 콜레스테롤 농도의 유의적인 저하효과를 나타내었다. 또한 콩나물 분말 투여는 고지혈증 동물들에서 투여량에 관계없이 혈장과 간, 신장, 심장 등 조직 중의 지질과산화물 수준을 낮추는 경향을 보였으나 그 저하효과는 대두 이소플라본 추출물의 효과보다는 낮았다. Catalase와 glutathione peroxidase 등 항산화효소들의 활성도는 고이소플라본콩나물의 투여로 대조군에 비해 유의적이지는 않았지만 증가되는 경향을 나타냈으며 혈장의 vitamin A수준은 5% 콩나물 투여군에서 유의적으로 높았고 vitamin E 수준은 유의적인 차이가 없었다. 이상의 결과로부터 이소플라본이 풍부한 콩나물의 투여는 고지혈증 동물에서 혈중지질 개선효과가 대두 이소플라본 추출물의 효과와 유사하거나 더 높은 것으로 나타났으며, 유의적이지는 않았으나 조직중 지질과산화물생성을 억제하고 항산화영양소 수준을 높이는 경향을 나타내었다. 이와 같은 결과는 본 실험에서 사용한 콩나물 시료가 높은 이소플라본 함량 이외에도 식이섬유를 다량 함유하고 있으므로 섬유에 의한 부가적인 효과에 의한 것으로 추정되며 콩나물의 영양적 우수성을 일부 입증한 결과로 평가된다.

Mung bean(Vigna radiata (L.) R. Wilczek var. radiata) is a legume that originated in India. It is the third most cultivated legume in Korea after soybean and adzuki bean. Recently, the use of mung bean seeds and sprouts in trendy foods such as rice noodles and Chinese-style stir-fry is expanding thereby increasing its demand. Subsequently, improvement of mung bean varieties is also being actively conducted. In this study, the important agricultural characteristics of 324 mung bean germplasm were recorded and statistically investigated. Seeds of the mung bean germplasm were cultivated at an experimental field located in the National Agrobiodiversity Center (Jeonju, Korea) and 10 quantitative agricultural traits were investigated. Basic statistics, correlation analysis, and principal component analysis were then performed. The results showed significant variations of the quantitative traits among the germplasms (p < 0.05). The days to flowering, maturity, and growth were in the ranges of 31~80, 22~72, and 57~110 days with means of 45, 47, and 92 days, respectively. The highest frequency (f = 192) was for lodging score with 11~50%, while simultaneous maturity (f = 182) was below 50%. Other quantitative traits related to yield including the number of seeds per pod (CV = 10.9%), number of pods per plant (CV = 41.2%), and one-hundred seeds weight (CV = 36.6%) also showed significant variations. Correlation analysis showed positive correlations between the days to maturity and one-hundred seeds weight (r = 0.41) and the days to growth and simultaneous maturity (r = 0.39). In contrast, one-hundred seeds weight was negatively correlated to the number of pods per plant (r = -0.41) and the days to flowering (r = -0.29). Similarly, the days to growth and the number of pods per plant had a negative association with each other (r = -0.29). The principal component analysis revealed the number of days to maturity as the most influential variable along the first principal component (23.7%). In general, this study revealed wide variations in quantitative traits among the studied mung bean germplasm, which could provide several options for cultivar development.

Reactive oxygen species are the byproducts of metabolic processes in the body, However, excessive amount may cause side effects such as cancer. Therefore, to reduce the production of these species, but their long-term administration at high doses may induce side effects. Hence, natural materials with antioxidant activities are attracting attention. Two of these natural materials are soybean sprouts and Hovenia dulcis Thunb. fruits, but few studies have evaluated the effects of their combination. Thus, we prepared a soybean sprout extract containing 1.5% H. dulcis Thunb. fruit concentrate (BHM) to develop a functional food material derived from natural products and then confirmed its physicochemical properties and physiological activity. Among the organic acids detected in BHM, malic acid exhibited the highest content of 1,451.03 ppm, and the main free sugars were glucose (645.48 ppm) and fructose (738.11 ppm). Taurine was the most abundant free amino acid at a concentration of 11.95 ppm, followed by those of arginine (10.97 ppm) and glutamic acid (10.16 ppm). Analyses of the mineral components revealed large amounts of Zn and Fe in BHM, and the respective total polyphenol and flavonoid contents in BHM were 957.16 and 601.93 ppm. The DPPH radical and H₂O₂ scavenging activities and reducing power indicated excellent antioxidant efficacy compared to the positive controls. Furthermore, blood alcohol and acetaldehyde concentrations were measured to confirm the hangover-relieving effects of BHM, with both significantly decreased (p<0.05). BHM displays potential for development as a functional food, and the results of this study may be used as basic data in further research.
