The purpose of this study is to investigate 5th grade elementary school girls' effort to recognize and use nutritional labels on processed foods and restaurant meals to encourage dietary behavior. The subjects (n=976) were divided into three groups (effort group, n=711; normal group, n=193; and no-effort group, n=72) depending on level of effort for the healthy dietary behavior such as eating balanced meals, eating three meals regularly, and eating meals slowly. In the effort group, the frequency of food intake for breads, ramen, noodles and fast foods was significantly lower, while frequency of food intake for fruits and vegetables and salad was significantly higher than in the other two groups. In the effort group, the ratio of the respondents that perception of nutrition labeling on processed foods and restaurant meals was 80.5% and 31.4% and the ratio of girls who checked the nutrition labeling at their point of purchase was 71.1% and 24.7%, respectively. Reasons given for not reading nutrition labeling for restaurant meals were 'not interested' for 34.6% of the effort group, and 52.2% of the no-effort group. Therefore, it is necessary to create an educational program on healthy dietary behavior, including how to read nutrition labeling and establishment of proper body image perception for elementary school girls.

The objective of this study is to develop a nutrition policy on food and nutrition labeling and education systems for fast food and carbonated soft drinks in Korea by identifying the fast food and soft drink use and by examining nutrition policies and labeling in Korea and other countries. Fast food is defined as food dispensed quickly at a restaurant generally offering a limited menu of inexpensive items, which may be mostly not nutritious. It is a growing component of the Korean diet, especially on children and adolescent population. Low nutrient dense beverages such as carbonated drinks are also increasing in the children and adolescent's diet in Korea and concern has been raised that these beverages may replace more nutritious beverage and provide empty calories. According to 2001 Korean national health and nutrition survey, fast food and carbonated soft drinks were most popular among 13 - 19 years old adolescents. Thirty six and 72 percent of adolescents consumed hamburger and carbonated beverage equal to or more than once a week, respectively. In United States, all processed food including soft drinks should disclose full nutrition information by nutrition labeling requirement.. Restaurant foods are not required to provide nutrition information currently, but legislation on mandatory nutrition labeling of fast foods with other restaurant foods has been proposed currently in US. The sales of foods of minimal nutritional value, such as soft drinks, in the nation's schools is regulated by the United States Department of Agriculture. Nutrition information about fast food in US has been provided by fast food companies, non-profit organizations, hospitals and government through internet, booklet and brochure, etc, but the information is available from only a few resources in Korea. This study suggests a nutrition policy on fast food and soft drink use which includes establishing mandatory nutrition labeling and developing nutrition education materials and programs by web-site, booklet and government and school programs in Korea.

There is a limitation to estimate vitamin $B_{12}$ intake due to the lack of data on vitamin $B_{12}$ content of Korean commercial foods. In this study, vitamin $B_{12}$ content was determined in favorite Korean restaurant foods, convenient or instant foods, fast foods and bakery products through a modified microbioassay using Lactobacillus delbrueckii ATCC 7830. Bulgogi and seafood & green pepper griddle had high vitamin $B_{12}$ content, 3.50 and $2.96{\mu}g$/100 g, respectively. Pork suyook, pork griddle and pollack griddle had 0.48, 0.31 and $0.32{\mu}g$/100 g of vitamin $B_{12}$, respectively. In stew, soft-tofu stew with seafood and doenjang stew with seafood had relatively high vitamin $B_{12}$ content, 1.93 and $1.44{\mu}g$/100 g, respectively. Bibimbap and 4 different types of rice porridge, beef & mushroom, chicken & ginseng, seafood or abalone, had 0.36, 0.08, 0.09, 1.64 and $0.13{\mu}g$/100 g of vitamin $B_{12}$, respectively. One serving of haejanggguk, yookejang, chuotang and galbitang had 5.97, 2.04, 2.63 and $1.91{\mu}g$ of vitamin $B_{12}$, respectively. One serving of samgetang and sulongtang had $2.89{\mu}g$ and $6.64{\mu}g$ of vitamin $B_{12}$. In noodles, one serving of cram noodle soup, bibim-nangmyeon, and mul-nangmyeon had 18.8, 1.21 and $0.38{\mu}g$ of vitamin $B_{12}$, respectively. One regular gimbap and one triangle gimbap contained 1.09-2.53 and $0.54-1.11{\mu}g$ of vitamin $B_{12}$, respectively. One cheese-burger, chicken-burger and bulgogi-burger had 0.76, 0.62 and $0.54{\mu}g$ of vitamin $B_{12}$, respectively. A plain bagel and a waffle contained 0.13 and $0.17{\mu}g$/100 g of vitamin $B_{12}$, respectively. Ready-made tomato sauce or cream sauce for spaghetti in a retort pouch contained only a trace of vitamin $B_{12}$. In conclusion, these results should contribute to improving the present food vitamin $B_{12}$ content database, most of which were cited from foreign data, thereby it could be helpful to estimate the vitamin $B_{12}$ intake of Koreans more accurately than before. It will also provide new information for dietary education related to vitamin $B_{12}$ and health.

The purpose of this study was to analyze Hanwoo usage in restaurants and to develop menus of lean cut Hanwoo. Restaurant served customers Hanwoo menus, with the exception of broiled or roasted meat, mainly to provide various menus to customers (4.14), due to customer needs (3.87) and utilizing stocks (3.59). On the other hand, the reason for not providing Hanwoo menus, with the exception of broiled or roasted meat was manpower shortage (3.63), lack of popularity (3.58), low profit (3.29), preservation of Hanwoos' original flavors (3.28) and complex cooking methods (3.22). Concomitantly, the restaurant owners' intentions to apply new menus with lean cut Hanwoo was 73.4%, showing an interest in developing new menus and recipes using lean cut Hanwoo suitable to the changing owner awareness of customer health and trends. This study has established a standard for developing cooking methods and developed menus according to classified recipes for lean cut Hanwoo, based on the survey of restaurants' current status of using Hanwoo and the owners' opinions. 20 menus using lean cut Hanwoo (rump or shank) were developed by $1^{st}$ and $2^{nd}$ cooking experiments, and in-depth interview of experts-groups. Of these, 12 menus suitable for the restaurant were finally selected based on the results of consumer's evaluation using JARS. Structured recipe flow diagram and recipe instructions were developed for future semi-processed or processing foods. Diverse recipe methods using lean cut Hanwoo were obtained from the study, however aggressive public relations work is required for promoting the developed menus.

The purpose of this study was to provide basic data for future research and suggest product development and market segmentation strategies by identifying the perceptions and consumption behaviors of vegetarians in each segment of the vegetarian market. According to food consumption value, a total of three market segments were derived, and the markets were named based on their characteristics, including 'environment and animal protection', 'multiple consideration' and 'low interest'. As a result of analyzing the perception of vegetarian-based food, "environment and animal protection" and "multiple consideration" presented positive perceptions of a vegetarian food product. Conversely, the group stating low interest expressed negative perceptions of the vegetarian food product. An analysis of the requirements for development for vegetarian-based foods products (eg. aquafaba), indicated that the development requirements for all products, except cultured and processed meats, were high.?Considerable demand was observed for vegetarian menus and vegetarian restaurants. As a result of the analysis on the necessity of the elements of the vegetarian restaurant menu, the subjects that stated "multiple consideration" had significantly higher awareness of issues related to vegetarian foods than others.

Objectives: The purposes of this study were to compare the degree of sodium reduction practice and estimate sodium intake by salty food preference. Methods: Sodium reduction practices, salty food preferences and estimated sodium intake were surveyed for restaurant owners (n = 80), employees (n = 82) and customers (n = 727) at the restaurants participating in the sodium reduction project in Daegu, Korea. Estimated sodium intake was performed by examining sex, age, body mass index (BMI), salty eating habit and dietary behaviors. Results: The degree of sodium reduction practice was significantly higher in salinity meter use (P < 0.001), low salt seasonings (P < 0.001) and efforts to make the foods as bland as possible overall (P < 0.001) in the restaurants participating in sodium reduction project than in homes (P < 0.001). The degree of sodium reduction practice appeared lower in the high salty food preference group than in the low-preference group in such items as efforts to make the foods as bland as possible overall (P < 0.05) and washing the salty taste and then cooking (P < 0.05). The high-preference group showed high-salt dietary behavior, including eating all the soup until nothing was left (P < 0.05) more than the low-preference group, but low-salt dietary behavior included checking the sodium content in processed foods (P < 0 .0 5) less than the low-preference group. The high-preference group was higher in the soup and stew intake frequency than the low-preference group (P < 0.05) and much lower in nuts (P < 0.05) and fruits (P < 0.05) intake frequency. The high-preference group had a higher salty eating habit (P < 0.05), salty taste assessment (P < 0.05) and estimated sodium intake (P < 0.05) than the low-preference group. Conclusions: The present study showed that the salty food preference was strongly associated with lower sodium reduction practice and higher estimated sodium intake.

본 연구는 식중독을 일으킬 수 있는 황색포도상구균(Staphylococcus aureus)의 검출을 이용하여 일식당의 식자재, 조리공정, 조리 기구, 조리 종사자의 오염수준을 예측하고 오염에 영향을 미치는 인자를 확인하고자 하였다. 시료는 서울시에 위치한 일식당에서 초밥과 생선회를 수거하였다. 몬테카를로 시뮬레이션을 통해 초기 오염수준으로부터 각 공정별 위해 인자를 고려하여 최종오염수준을 예측한 결과, 새우 및 문어초밥의 경우, 모든 초밥이 저장기간 동안 S. aureus가 증식되는 것으로 나타났으며 특히, 문어 초밥이 가장 높은 오염도를 보였다. 이는 생선회가 온도변화에 따른 균의 증식이 활발하고, 일식당에서 초밥을 섭취하기 직전에 초밥 중 생선회의 급속한 온도 변화가 나타나 기 때문으로 판단된다. 초밥의 민감도 분석 결과, 완성된 초밥의 섭취 시 온도의 민감도 값이 0.419로 최종오염수준을 증가시키는 것으로 예측되었다. 두 종류의 초밥에서 동일하게 보관 시간과 섭취 시의 온도가 최종 오염수준에 가장 크게 영향을 주는 것으로 나타났다. 이는 일정 시간이 지난 후 초밥을 섭취하는 것이 균의 농도 증가에 가장 크게 영향을 미친다는 것으로 초밥을 조리 후 즉시 섭취하는 것이 균의 증식을 크게 예방할 수 있음을 알 수 있다. 연어, 도미, 방어회의 경우 섭취 시간에서 민감도 값이 0.71로 가장 큰 민감도를 나타내었고, 섭취 시 온도 또한 민감도가 크게 나타났다. 초밥의 시나리오 분석 결과, 실온 보관 시, 섭취시간이 2시간 이내일 때 식중독을 유발하지 않는 안전한 수준임을 알 수 있었다.
