This study was performed by questionnaire to investigate current use of native local foods of adults in Gyeongju classified by age. The subjects were consisted of 421 citizens(217 males and 204 females) living in Gyeongju. The findings are summarized as follows: 'Institute' scored high as 30.6% in the main responsible body for the succession of local foods. The most emphasized points to popularize the local foods was to 'taste'(36.4%). a point to be considered to develop tourism product of the local foods was to 'development of recipes acceptable to the people of today'(24.6%). The recognition rate score of native local foods of Gyeonngju area was 'Hwangnamppang', 'Hanjeongsik', 'Ssambap', 'Haejangguk', 'Hoe(Gampo)', 'Memilmukmuchim', 'Gyodongbeopju', and 'Yugoa' in the order. On the other hand, the recognition rate score for 'Ssukgulrei', 'Borisudan', 'Dalraikkakdugi', 'Hwanggeumju', 'Baesuk', 'Gyeojachae', 'Gungjungjeongol' was very low. The preferred and intake native local foods of Gyeongju area was 'Hanjeongsik', 'Ssambap', 'Hoe(Gampo)', 'Haejangguk', 'memilmukmuchim' in that other. On the other hand, the preference for 'Ssukgulrei' 'Borisudan', 'Hwanggeumju', 'Baesuk' and 'Dalraikkakdugi' was very low.
The purpose of this study was to analyze food behavior of tourists to develop consumer-oriented local cuisines for the Goseong dinosaur festival. A random sample of 518 tourists took part in one-on-one interviews which were conducted between May 7 and May 28, 2006. The highest percentage of people were in the 30-39 age group, and the over 60 years were the second highest. The participants resided mainly in urban areas of Gyeongnam province and other large Korean cities. Most of the tourists had breakfast at home before leaving for the festival, 27.8% skipped breakfast or bought and ate various food s as a breakfast on the way to the main venue. The proportion of the tourists who wanted to eat lunch at outlets in the main venue was 39.8%, while 34.6% of the tourists brought their lunch boxes. Only 14.5% had a desire to eat lunch at restaurants in Goseong. 33.8% of the tourists were willing to pay 5,000-6,000 Won per capita for the lunch, 15.6% wanted to pay 7,000-10,000 Won per capita. Noodles and Gimbab were chosen as favorite dishes for lunch by 15.4% of tourist while Bibimbab was selected by 12.0%. Various aspects of food behavior were different between the two predominant age groups. For example, the prices and the kinds of meals they wanted, and the places they preferred to eat meals. Therefore, it is suggested that more than 2 kinds of local cuisines have to be developed for the predominant age groups. The price of the local cuisine for the 30s age group should not exceed 5,000-6,000Won, whereas less than 10,000Won is an appropriate price for the over 60s. Menus for children also need to be developed, along with breakfast menus specifically for the 30s age group.
This study was conducted to investigate factors affecting gone density of university students in Seoul area. Data for food habits, exercise and health-related behaviors were obtained by self administered questionnaires. BQI(bone quality index) of the subjects was measured by an Quantitative Ultrasound(QUS). The results are summarized as follows: The average hight, weight BMI and osteopenia percentage of the male and female student were 173.3cm, 68.6kg, 22.7 and 24.2%; 161.4cm, 54.4kg, 20.9 and 55.5%, respectively. The BQI and Z-score of the subjects were 99.6, -0.3 in male student group, and 82.7, -1.1 in female student group, respectively. Height, weight, fat weight, fat mass and BMI were positively related with BQI in female group. BQI was positively affected by breakfast and frequence exercise in male student group. In female student group, frequency exercise was positively related with BQI. The result of this study revealed that the desirable food habits, dietary behaviors and health-related lifestyles may have a beneficial effect on bone density. They should have practically and systematically organized nutritional education on optimum body weight, good eating habits, weight bearing exercise for higher bone density level.
The present study examined the characteristic of regional food culture observed in prehistoric Daegok-ri petroglyph based on the history of art, archeological materials and existing whale eating customs. Daegok-가 petroglyph expressed animals in the sky, on the land and in the sea. According to the relic, the most preferred land and marin animals were deer and whale, respectively. In terms of petroglyphic techniques. earlier patch engraving was used mainly to express marin animal whale, and later line engraving to express land animal deer. This implies the possibility that as whale hunting declined due to regional environmental change the source of protein was switched to land animals. Among relics found in Dongsam-dong shell mound, which is a remain from the Neolithic Period, whale bones appear only in shell mounds of the Neolithic Period in coastal areas, and shell mounds until the Ironze Age, which were the agricultural Age, were found the bones of land animals such as deer and wild boar. This shows that in the petroglyph thematic land animals expressed in line engraving, which is a technique later than patch engraving, were major food resources for the supply of protein. Moreover, in terms of art, Daegok-ri petroglyph describes 'advanced hunters', suggesting that it was the Neolithic Period and showing 문 aspect of regional food culture based on hunting and fishing. The credibility, which prehistoric men expressed in Daegok-ri petroglyph before the invention of letters, was also proved by archeological articles.
This study is intended to investigate the wine consumers' reason of drinking and purchasing behavior according to their product involvement. Questionnaires were obtained from wine consumers at wine retailer stores. Trained researchers of this particular study conducted survey and finally 230 questionnaires were analyzed using SPSS package program(v.12.0). The subjects were categorized three different groups(high, medium, and low) based on their wine involvement. The further analysis showed that differences in reasons of wine drinking and purchasing behavior according to their involvement levels, and the characteristics of three segments were summarized at the end of the results. Consumers in high involvement drink wine mainly because they wanted to enjoy various wine experiences and have abundant knowledge for wine. Consumers in medium and low involvement would like to drink due to enjoyment of wine drinking. Expenses of purchasing, quantity and frequency of wine purchasing, country of origin, and sources for wine information showed differences among three consumer groups, but differences were not presented in type of wines and purchasing place by consumers' wine involvement.
This exploratory study is to analyze the status of star menus and suggest the development strategy of star menus in the western restaurants of the tourism hotels in Seoul. The data was collected from the chefs who have been working over 15-years in tourism hotels in Seoul by judgement sampling. The questionnaire was composed of Miller and Pavesic's 'Fifty tips for a successful menu' and Khan's 'The evaluation of menu item development', The 30-menu items were selected from the 1st survey on the menu items that were high in both popularity and contribution margin by menu engineering method. The selected menu items were analyzed by 14 lists: simplicity, ready availability of ingredients, quality, flavor, presentation, preparation, service method, nutrition quality, preference, profitability, serving temperature, descriptive copy of menu and publicity. As a result of the study, appetizer category was recorded the highest score by 4.09. Smoked salmon, Tomato and mozzarella cheese, Cream of mushroom, Cream of asparagus, French onion soup, Grilled beef tenderloin, Grilled rib-eye steak, Roasted lamb rack, King prawn, Seafood spaghetti, Chef's salad, Caesar salad, Organic salad, Fruit plate, Italian tiramisu and Yogurt ice cream were recorded high score. The development strategy of star menu is belows : the menu writer must consider the productivity, effectiveness, popularity and profitability, the regular customers want varieties and creativity in the menu and the operators have to include the star menu items in the set menu.
This study was performed to determine the effect of Takju(Korean turbid rice wine) lees on the serum glucose level in streptozotocin-induced diabetic rats. 24 Sprague-Dawley male rats were divided into three groups: normal control(NC), diabetic control(DC) and diabetic rats(DS) were fed on experimental diet and water ad libitum for 4 weeks. DS diet was containing 20% Takju lees. Body weight gain and food Efficiency Ratio(FER) were significantly lower in DC and DS than NC. DS tended to have higher weight, weight gain and FEF than DC nevertheless food intake. Therefore Takju lees could possibly complement casein as a protein source. Gastrointestianl transit time in DS significantly decreased than NC while not significantly than DC. Serum lipid profiles and AST. ALT and amylase were not significantly different between diabetic DC and DS. Blood glucose was measured at fasting state and 30, 60, 90 and 120 minute by oral glucose tolerance test, DS tended to lower the mean(± SE) incremental blood glucose concentrations than DC and was significantly low at 120 min. But incremental AUG(area under the curve) of postprandial glucose response was not significantly different. In conclusion, in spite of high contents of carbohydrate Takju lees perhaps have a benefit effect on the diabetes.
두부는 식물성 단백질 자원의 식품으로 세계적으로 잘 알려져 있으며 우리나라의 전통식품이다. 최근 두부가 건강식품으로 인식되면서 품질 고급화를 위한 방안으로 화학 첨가물이 아닌 천연응고제로서 석류즙을 사용하여 두부를 제조하여 기계적 및 관능적 특성의 품질특성을 조사하고 저장성을 살펴보았다. 두부의 수율을 대조군이 485g/500ml이었으나 석류즙 첨가 두부군에서는 석류즙 3%(49.3g/500mL)가 가장 높고 석류즙 2%, 4% 순이었다. 두부여액의 탁도는 석류즙 첨가량이 많아질수록 높에 나타났으며 여액의 pH는 석류즙 첨가 두부가 대조군보다 낮게 나타났다. 두부의 색도에서 L(lightness)값은 대조군이 가장 높았으며 탁한 붉은 색의 석류즙 두부는 첨가량이 증가될수록 감소하였다. a(redness)값은 석류즙 첨가량이 증가될수록 커졌으며 b(yellowness)값은 대조군이 석류즙 첨가 두부군보다 높았다. 두부의 texture에서 경도(hardness)는 석류즙 첨가 두부가 더 단단하였고 응집성(cohesiveness)은 석류즙 4%, 5% 첨가군이 대조군보다 높고, 석류즙 1%, 2%, 3% 첨가군보다 낮았다. 탄력성(springness)은 P4〉P5〉P3〉P2〉P1순이며 검성은 석류즙 3%첨가군이 GDL두부와 유사한 특성을 보였으며(p〈.001), 부지짐성(brittleness)은 석류즙을 많이 첨가할수록 높아지는 경향이 있었다. 두부를 0℃에 저장하는 동안 pH는 대조군은 증가하며 석류즙 첨가 두부는 감소하는 경향을 보였으며 산도에서 대조군은 석류즙 첨가 두부와 같이 증가하였으며 두부의 저장성에서 대조군은 12일 지나면서 107 CFU/g을 넘어 부패가 진행되었으나 석류즙첨가 두부는 세균의 증식속도가 감소되어 전 기간동안 대조군에 비해 저장성 연장을 볼 수 있었다. 두부의 미세구조에서 석류즙 2%, 3% 첨가 두부가 대조군과 균일하게 구조를 나타냈으며 석류즙 첨가량이 증가할수록 입자가 크고 불규칙하며 거칠었다. 두부의 관능특성에서는 외관이 기호도는 대조군이 가장 높았으나 석류즙 첨가 두부군에서는 석류즙 2% 첨가 두부가 외관(appearance), 향미(flavor), 맛(taste), 질감(testure)에서 가장 높았다.

The purpose of this study was to investigate the consumption and perception on the effect of cooked rice mixed with multi-grain (CR-MG). Reason for like and dislike, intake frequency and variables related with the satisfaction of CR-MG were also investigated. The data for the analysis was collected from 315 adults who were residing at Seoul·Kyeonggi and Kangwon area and analyzed by the SPSS 11.0 program. The result showed that 84.8% of the respondents consumed CR-MG, showing significant difference by gender and occupation (p〈0.05). It also revealed that they consumed it knowing their effect, showing significant difference by all general characteristics except for resident area and BMI, respectively. Kind of multi-grain (MG) mixed with cooked rice was high in the order of SoRiTae (80.1%) 〉 brown rice (73.4%) 〉 black rice (72.7%) 〉 waxy rice (61.0%), respectively. As for the mixing type of MG, 61.4% of the respondents preferred non-mixed product rather than pre-mixed product. 2 or 3 kinds were preferred numbers of MG mixed with rice, showing significant difference by age (p〈0.001) and marital status(p〈0.05), respectively. 59.9% of the respondents answered 'high nutritive value more than polished rice' as the major reason for like, whereas 31.3% answered 'greatly rough more than polished rice' as that for dislike, respectively. By the use of multiple regression analysis, it revealed that health was the most significant variable which affect the satisfaction of CR-MG. From these results, it was suggested that in view of the high consumption and intention to continue the intake of CR-MG, following studies should be conducted to improve the preference of CR-MG.
The objectives of this study were to develop calcium enriched menu for the aged and to investigate physicochemical characteristics and consumer acceptances of the menus. four kinds of the menu were developed with emphasis on calcium enriched food materials of red pepper leaves seasoned vegetables for menu1, shrimp for menu2, anchovy for menu3, seaweed for menu4. one portion of calorie, polysaccharide, protein, fats and calcium for the aged were calculated as 567kcal, 92.8g, 21.3g, 12.6g 223.1mg, respectively based on the recommended daily allowances for adults. Calcium content increased in the lowest value of all(p<0.05). The hunter lightness(L) values of barely rice in menu 1, radish soup in menu 1, chopped roast chicken in menu 4 and radish salad in menu 2 had significantly the highest values of all(p<0.05). The calcium enriched menus for the aged were successfully developed and these data could be used as basic informations for the improvement in health and life of the aged.
In this experiment, I used three samples of oils. The oils that I used were hydrated soybean oil, pure soybean oil and regular soybean oil. The group of rice was fried in the each sample of oil that had not been used for a few seconds. Rice was used after frying at 230-235℃ every four hours terms and total frying hours was 12 hours. The hydrated soybean oils was least affected in rancidity. The other two oils were more affected in rancidity than the hydrated soybean oil. However, the trans fatty acid in hydrated soybean oil was 36.5%. The diameter of the poped rice that was fried in pure soybean oil and regular soybean oil that had been used 12 for hours was reduced while the diameter of the popped rice fried in the hydrated soybean oil was not reduced. Also, the groups of rice fried in the pure and the regular soybean oil that had been used for 12 hours reduced the hardness in rice while the group that fried in the hydrated soybean oil at the 12th hour kept the hardness well. In sensory evaluation, rancidity order was found apparently in the pure soybean oil that had been used for 12 hour and in the regular soybean oil that have been used for eight hours and 12 hours. Only the hydrated soybean oil did not have distinctive rancidity order at all. The degree of the crispiness was reduced in the pure soybean oil and in the regular soybean oil at 12th hour frying. However, the hydrated soybean oil preserved the crispiness well until the end of 12 hours of frying. In overall preference test, the pure and regular soybean oil that had been used for 12 hour were not preferable. In conclusion, I found that the group fried in the hydrated soybean oil was better in every evaluation than the groups fried in the pure soybean oil and in regular soybean oil. The hydrated Soybean oil may be better to be used in food manufacturing if the trans fatty acid in the hydrated soybean oil can be reduced.
The quality characteristics of cookies containing brown rice flour, which has a greater variety of functional components than wheat flour, were studied. The results of the pasting properties shows that the inclusion of brown rice flour to the wheat flour-mixture did not affect the pasting temperature for up to 30% inclusion. The total dietary fiber and total polyphenol content increased and color of the cookies became darker with increasing brown rice flour content. According to the results from TA on texture, the hardness decreased and the crispness increased significantly(p<0.001, p<0.05, respectively) with increasing brown rice flour content. From the acceptance test, the aroma and texture of the cookies with added brown rice flour were significantly(p<0.001) lower than those of the wheat flour cookies. However, the appearance, taste, and overall acceptance of the cookies with added brown rice flour did not differ significantly from those of the wheat flour cookies. According to the results from the sensory evaluation, the savory aroma of the cookie with 30% brown rice flour was significantly strong(p<0.001). The brown rice flavor of the cookies with brown rice flour was significantly stronger(p<0.001) than that of the wheat flour cookie, but there were no significant differences among the cookies with brown rice flour in it. The crispness of the cookies increased significantly(p<0.001) with the inclusion of brown rice flour in the mixture, especially for the mixture with 30% brown rice flour which had the highest value of crispness among the cookies. The graininess and brown color of the cookies increased significantly(p<0.001) with increasing brown rice flour content, especially for the mixture with 30% brown rice flour which had the highest values among the cookies.
This study is based on the utilization of pine mushroom for processing products by development of pine mushroom Jung-Gwa. The results were summarized as follows: Pine mushroom Jung-Gwa were prepared with four different amounts (20, 30, 40, 50%) of honey. Pine mushroom Jung-Gwa color value was the highest by 20% soaking honey-water product and 40% soaking honey-water product was the lowest. Strength and hardness of 20% soaking honey-water product was the highest. Appearance to product of 50% soaking honey-water was the highest preference by all age of except 20's. The honey content of more and more external appearance preference was became higher. Product of 40% soaking honey-water was best by flavor of pine mushroom Jung-Gwa. A sugary tastes comparison 50% soaking honey water to 40% soaking honey water was not distinction. The texture was appeared a statistically significant difference by products of 20%, 30% soaking honey-water. Product of 20% soaking honey-water was favorite in 20's and product of 30% soaking honey-water was favorite in 30's. In overall preference test for pine mushroom Jung-Gwa of 40% soaking honey water was preferred by all age. Oligosaccharide helped geriatric diseases and cheaper. Thus this study used oligosaccharide but the result was not a statistically significant difference of pine mushroom Jung-Gwa products quality by comparison honey-water to oligosaccharide. Therefore oligosaccharide utilization products was thought worth a lot more by processing price and functional.
The purpose of this study was to identify the influence of school foodservice dietitians' work value on job satisfaction, organizational commitment, and turnover intentions. Also, this study explored the role of the expectation to the institution of nutrition teachers as a moderating variable in three relationships: 1) between work value and job satisfaction, 2) between work value and organizational commitment, and 3) between work value and turnover intentions. This study surveyed dietitians who worked at school foodservice in Kyunggii and Daegu·Gyeoungbuk province. A total of 509 responses were collected using on-site survey and online survey (response rate 59.3%). This study conducted hierarchical regression analysis to test the moderating effect of the expectation to the institution of nutrition teachers. Results of hierarchical regression showed that work value of status upgrade had a positive effect on job satisfaction to promotion opportunity and salary, and such effect was more significantly apparent in high expectation to new work. In addition, work value of status upgrade had a positive effect on turnover intention, and such effect was more significantly apparent in low expectation to new work environment improvement. Work value of work activity preference also appeared to have a positive effect on organizational commitment, and such effect was more significantly apparent in high expectation to social status and professionalism.
