This study was conducted to investigate the contemporary dietary life of residence in Kyunggi province. People living in Kimpo, Yoju districts(farm villages), Kapyung districts (mountain villages) and Hwasung districts (fishing villages) were selected for this research as subjects from August S to 19,1997. The results of the survey are summarized as follows: 1. Cooked rice was a staple food. However nuddles and soojaebees(soup with dough flakes) was taken as lunch or snacks but Juk(rice guel) or Dduk(rice cake) was not treated as a meal. 2. Dishes were consisted with soup or chigae, kimchi and namul(seasoned vegetables), and fishes, meats, salted sea foods, dried fishes, jangacchi(dried seasoning radish) were also taken by sometimes. 3. Soy sauce, bean paste, red pepper bean paste were made by every home even if they were very busy. 4. Festival days such as New Year's Day, daeborum(the 15th day of January), chusok(mid-autumn festival), and kosaa(October ceremony) and dongee(one of 24 seasons by lunar calendar) are skipped oftenly and slowly forgotten by people. They do not celebrate Samgin-nal(the third day of March), Buddha's birthday(the 8th day of April by lunar calendar), danoh(the 5th day of May), yoodoo(the 15th day of June), chilsok(the 7th day of July), Jungyang(the 9th day of September) and the last day of the year either 5. Due to improved kitchen system, we couldn't see the old kitchen devices.
This study was conducted to investigate the uses of Aster scaber. The survey methodology employed was a questionnaire, which was used to interview 272 (37.8%) males and 448(62.2%) females from the Seoul and Kyunggido areas. The main results are as follows: 40-50 years old like and eat Aster scaber more frequently than 10-30 years old. The most popular reason provided for the preferance of Aster scaber was good health benefits. People indicating a dislike for Aster scaber had generally fewer previous experiences of eating this plant. Respondents who regularly ate healthy foods preferred prepared Aster scaber to others foods(p < .001). The main purchasing place was traditional markets and supermarkets. The main cooking method was boiling with addition of seasoning. Aster scaber was purported as having the following characteristics "low calories and thus great as diet food'(4.03), 'ability to prevent adult disease'(3.95), 'high in vitamins and minerals'(3.89), and 'high fiber content which prevented constipation'(3.85). However, it was not associated with 'astringent taste'(3.51) and was regarded as 'fat accumulation restrainer and remover of heavy metal'(3.53). Recognition and eating experience was low for Aster scaber kimchi and rice bread, bread, sauce and Aster scaber added health drinks. However opinion of its taste was regarded highly.

Purpose: With the increase of going out to eat, reducing the sodium in restaurant foods has a crucial impact on reducing sodium intake. This study aimed to assess the current status and perceptions of restaurant staffs related to reducing sodium use in restaurants. Methods: Restaurant managers and chefs (n = 312) in Seongnam area completed a questionnaire on the current status related to sodium use, the barriers to practice for reducing sodium use, support needs, and the practicability of methods for reducing sodium use in restaurants. Results: The percentage of restaurants in the preaction stage (including the precontemplation, contemplation, and preparation stages) for reducing sodium use was 79.7%. Logistic regression analysis showed that measuring salinity while cooking was associated with measuring seasoning (OR, 4.761; 95% CI, 2.325 ~ 9.751), action/maintenance stages of behavior change (OR, 2.829; 95% CI, 1.449 ~ 5.525) and providing salinity information of restaurant foods (OR, 6.314; 95% CI, 2.964 ~ 13.45). Maintaining taste and hindering the cooking process were the main barriers to reduce sodium use. The total practicability of actions for reducing sodium was higher in staffs who worked in restaurants that measured seasoning and salinity while cooking (p < 0.05 and p < 0.01, respectively). The hardest item to practice was 'purchase foods after comparing sodium content in the nutrition labeling'. 'Avoid serving salt-fermented foods as side dishes', 'serve small portions of kimchi and less salty kimchi', and 'put up promotional materials for reducing sodium intake' were selected as easy items to perform. The majority (82%) was willing to reduce sodium in restaurant foods under the support of local government and they desired the promotion of participating restaurants and education on cooking skills to reduce sodium. Conclusion: Measuring seasoning and salinity while cooking is a meaningful practice that is associated with stages of behavior change and the practicability of actions for reducing sodium. It is necessary to provide support and education with a gradual approach to staffs for reducing sodium in restaurant foods.

To lessen the initial level of microorganisms, electrolyzed acid-water was used as washing and brine water in the manufacturing process. On the washing and salting processes, application of electrolyzed acid-water showed a possibility to lessen the microorganism level of Chinese cabbage effectively. Microbial level of Chinese cabbage was reduced to about 1/4 level by salting and washing process with electrolyzed acid-water while Chinese cabbage salted with tap water increased to about 1.7 times. And no coliform and E. coli were detected. However significant differences between seasoning mixtures prepared with electrolyzed acid-water and with tap water were not observed in microbial levels. Relatively low level of total count in kimchi prepared with electroyzed acid-water was kept until 15 days of fermentation at $10^{\circ}C.$ Any significant difference between them was not observed after 20 days of fermentation. pH and acidity were showed the same tendencies as microbial count.
The aim of this study was to investigate the quality characteristics of Kimchi, prepared with seasoning fluid, vinegar, and mustard extract to inhibit the proliferation of microorganisms and extend the edible period during fermentation at $25^{\circ}C$. We also added perilla leaf, endive, and mustard leaf to Kimchi to improve the flavor. The pH of control Kimchi fluid over 1 day after Kimchi processing, was $5.40{\pm}0.01$ and that of the experimental groups in which vinegar and mustard extract were added was $4.51{\pm}0.01{\sim}4.52{\pm}0.01$, which was lower than that of the control. As the fermentation progresses, the pH of the control decreased rapidly and that of the experimental groups decreased slowly. The initial titratible acidity of the control was low and 3 days later reached $0.95{\pm}0.04$. However, that of the experimental groups was $0.42{\pm}0.01{\sim}0.43{\pm}0.02$ and 5 days later reached a level similar to that of the control. The salinities of the Kimchi juice of both the control and the experimental groups were $2.67{\pm}0.06{\sim}2.80{\pm}0.10$% after 1 day and decreased during fermentation. The amount of lactic acid bacteria of the control was $8.17{\pm}4.01{\times}10^8cfu/g$, 1 day after the Kimchi processing and that of the experimental groups was $2.70{\pm}2.08{\times}10^7{\sim}3.63{\pm}2.80{\times}10^7cfu/g$. After 3 days, these were $3.13{\pm}1.94{\times}10^{11}cfu/g$ and $2.47{\pm}2.23{\times}10^9{\sim}8.03{\pm}3.71{\times}10^9cfu/g$, respectively. According to the result of sensory evaluation, throughout the entire period of the experiment, all sensory items such as color, odor, taste, texture, and total acceptability of the experimental groups were better than those of the control group (p<0.05). Especially, Kimchi in which perilla leaf was added was the best. With the addition of vinegar and mustard extract to the Kimchi, microorganism proliferation was inhibited and the edible period was extended. The minerals, vitamins and antioxidants of leaf vegetables could therefore be obtained.

For extension of storage period of cabbage-kimchi, effects of heat treatment as well as nisin or yucca extract were examined on the growth of microbes. Firstly, when kimchi was heated at various temperatures in polyethylene plastic bottle or membrane pouch, the optimum inhibitory condition giving no sensory change was at $80^{\circ}C$ for 30 min in a plastic membrane pouch and this treatment made a reduction of $0.3\;log_{10}CFU/g$ in total microbes. The result showed that use of plastic bottle was inefficient due to low heat transfer rate. Interestingly, pasteurization of seasoning pastes at $80^{\circ}C$ for 30 min separately from cabbage resulted in better inhibitory effect reducing $0.5\;log_{10}CFU/g$ of total bacteria and $1.0\;log_{10}CFU/g$ of lactic acid bacteria, and this operation was regarded as a promising inhibitory method. Secondly, when nisin and yucca extract were separately added in kimchi, microbial growth was inhibited during storage period and their inhibition effects were enhanced at lower temperature.
Consumer's perceptions of the qualities of food and food-related services were surveyed through questionnaires by 672 adults randomly selected from 20 industrial foodservice in Pusan and Kyeung Nam area. The results are as follows: 1) By age, the elderly group gaved the highest mean score not only for freshness and temperature among the food characteristics but also for cleanliness of dishes and materials of dishes among the food-related service. 2) By occupation, the white collar worker group gaved the highest mean score in all characteristics of food and food-related service than did the blue collar worker group. Especially for courtesy of employees, the mean rating given by the white collar worker group was 3.15/5.00, but by the blue collar worker group was 2.67/5.00. 3) Good appetitive group rated taste of food 3.15/5.00, quality of food vs. food price 3.17/5.00, and freshness 3.15/5.00. But poor appetitive group rated taste of food 2.44/5.00, quality of food vs. food price 2.65/5.00, and freshness 2.70/5.00. 4) Men agreed that the rice and soup were right in amount. And women responded that the rice was in a large amount and the soup was not enough. 5) The white collar worker group agreed that the rice, the soup, the side dish, and the kimchi were right in amount. However the blue collar worker group agreed that the rice was right in amount, the soup and the side dish were not enough, and the kimchi was in a large amount. For seasoning of food, the white collar worker group responded that the salty taste and the hotness were just right. But the blue collar worker group responded that the food was neither salty nor hot at all. 6) The taste of food was shown to be positively correlated (p<0.001) with various food item combinations, freshness of food, and the variety of cooking methods.

This study surveyed dietary intake and adherence to the Korean national dietary guidelines in Korean adolescents. To elucidate basic data for use in nutrition education, which aims to improve adolescent compliance with the national dietary guidelines and to increase the intake of dietary fiber, we evaluated the sources of fiber in adolescent diets. This study included 182 male and 212 female students from 2 middle schools in the Jeonju province. From November 15~20, 2011, we surveyed the students for general characteristics, adherence to the Korean national dietary guidelines, and dietary intake. Dietary fiber intake was $16.57{\pm}6.95$ g/day for male students and $16.14{\pm}7.11$ g/day for female students. The food groups that contributed most to dietary fiber intake were (in descending order) cereals, vegetables, seasoning, and fruits. The fiber-containing food items consumed most were cabbagekimchi, cooked rice, instant noodles, and cabbage. Based on adherence to the Korean national dietary guidelines, the vegetable-based intake of dietary fiber in groups 1 (score 15~45), 2 (score 46~52), and 3 (score 53~75) were $4.41{\pm}2.595$ g/day, $4.12{\pm}2.692$ g/day, and $5.49{\pm}3.157$ g/day, respectively (p 0.001). In addition, the total intake of dietary fiber varied significantly among the three groups (p 0.001) as follows: Group 1, $14.99{\pm}6.374$ g/day; Group 2, $15.32{\pm}6.772$ g/day; and Group 3, $18.79{\pm}7.361$ g/day. In this study, we discovered that adherence to the Korean national dietary guidelines correlates with improved intake of dietary fiber. Therefore, marketing and educational development is needed to promote adherence to the Korean national dietary guidelines. In addition, nutritional education is needed to improve dietary fiber consumption through the intake of vegetables and fruits other than kimchi.

This project was undertaken to compare the Korea Food Standards Code, Food Additives Code and Codex Food Category System and to propose necessary measures to improve the regulatory system of food additives which are scientifically reasonable and harmonizable with international standards. Current food grouping and nomenclature in Korea were specifically compared with the Codex Food Category System and measures to solve any problems in connection with the use of additives in traditional foods were attempted. Among the food commodities in the Korea Foods Standards Code, 8 food groups including Korean confections, semisolid starchy syrups, bean curds and starch gels, edible oils and fats, tea beverages, seasoning foods, kimchi and salted vegetables, and ginseng products were chosen to propose some improvement measures to harmonize the classification, nomenclature, definition and use of additives with the Codex standards.
Ninety-three weaning children, 8-36 Mo. old wererandomly selected from rural areas of South Korea. Food and nutrient intake level were measured by the weighing-interview method for two consecutive days in December 1976. Their weaning pattern, dietary pattern, food and nutrient intake level were analyzed. A brief summary of 4he finding follows; 1) 80% of the rural children completed the weaning by the age of 24 months. 2) 44% of 8-12 month olds were living only on breast mil while the rest of the age group received regularly a supplementary food. 3) Over half of the 8-36 Mo old children investigated were receiving the same dietary pattern, arbitrarily called 'Diet K'. Diet K consists of rice-Kimchi-seasoning-oil which is the basic components of an average Korean adult diet. This very composition of the diet K and no other variety of food included inevitably result in low intake of vitamin A, iron, calcium and riboflavin for the children. 4) The weaning children were found to be taking all nutrients except niacin in amount far from sufficient to recommended level. Particularly low were the intakes of good quality protein, iron, vitamin A, riboflavin and vitamin C which met only 15%-37% of the recommended level for 12-36 Mo. olds. 5) It was concluded that majority of the rural children of weaning age in Korea are given the simple diet K and feeding the weaning children only with the basic dietary pattern of adults can not meet the nutritional requirements. This is a part of the study supported by the ROKG/USAID Health Planning Project.
