  • This study was conducted to compare families eating-out behavior in relation to family life cycle in order to provide basic information on nutritional education about eating-out. The data were collected by the survey method from 440 families who lived in apartment complexes in Kyong-ju and Seoul. The structured questionnaire included items about the frequency of eating out, the choice of eating-out menus, the decision maker of the eating-out process, the attitudes toward eating out and the general characteristics of the families. The major results are as follow: 1) In the cafe of telephone delivery service, and eat-in restaurants, the subjects showed statistical significance (p < 0.01). With respect to telephone delivery service, families in Step II used it most frequently, but families in Step I rarely used it. With respect to eat-in restaurants, families in Step II used them most frequently but families in Step IV rarely used them. 2) In all the family life cycle steps, the most favorable menu was fried chicken for take-out type, Chajang noodles, fried chicken and pizza fur telephone delivery, pizza for internet delivery, raw fish and beef for eat-in restaurant, Docbokki, laver rolled rice and ramyun for convenience flood stores. 3) The wife was most influential in making decisions about the take-out type (p < 0.001). In the case of telephone deliveries (p < 0.001), the wife was the most influential in the families of Steps I and II, but the children were the most influential in the families of Steps III and IV. In the case of eat-in restaurants (p < 0.001), the husband had the most effect on the decision-making process. In the case of convenience flood stores (p < 0.001), the children were the most influential in the families in Steps III and IV. In most family life cycle steps, each of them chose their own meal. 4) from a factor analysis perspective, attitudes toward eating out have been grouped according to two factors, namely 'Advantage' and 'Nutrition'. No factor showed a significant difference among the family life cycle steps.

  • This study aimed to develop food truck concept based on demographic characteristics by using conjoint analysis. This study investigated the attributes importance and attributes level based on gender, age and income. Results of the research were following. First, as a result of analyzing the attributes importance and attributes level of gender, age, and income, it found that the price was more important than the type of food. The shape of food, a design of the truck and service are the following features of the attributes importance. Second, in the entire of market analysis, packaging was the most important factor next to the price and the food shape. Third, according to gender analysis, male and female prefer Korean style with price range of 5,000~7,000 won. Men prefer take - out menu such as plastic packaging and traditional truck design. Also, the study showed that women prefer having a meal at restaurant, paper packaging style and modern design. Fourth, according to the age analysis results, all of ages group prefer the price range of 5,000~7,000 won except for people who are 60s and beyond. Also, in the food type, people prefer Western style in their 20s, Japanese style in their 30s and Korean style in their 40s, 50s, 60s. Fifth, according to income analysis, Western menus with income of 4,000,000~5,000,000won are preferred a price range of 7,000~10,000won and Japanese menus with income more than 5,000,000won are preferred a price range of 7,000~10,000won.

  • As the school lunch program is expanding to middle and high schools in Korea, a survey has been conducted to provide informations of the types and menus which are most favored on 190 middle and high school students in Metropolitan area. The sources/menus of foods relating to their lunches were proportionally ranked as: school food services (54.2%): individual lunch-box from home(37.4%); take-out lunch box(3.7%): school cafeterias(1.6%): and commercial restaurant, undefined, and skip a meal(1.1%). For the present practices for lunch, 52.1 and 47.9% of the students responded satisfaction on its sources and menus, respectively. A meal valued less than 2,000 won was paid by 54.9% of the respondents. In the meantime, 33.7 and 55.4% of the students were unsatisfied with lunch box from home and school cafeteria of the present lunch practices, respectively. The reasons against their satisfactions were enumerated as their preferences for take-out lunch box(22.2%), school cafeteria(21.0%), outside restaurant(17.3%), individual lunch-box from home(16.1%), school cafeterias(8.6%), and undefined (14.8%). For the individual lunch-box from home, two major obstacles, i.e., it is neither warm to eat, nor diverse/properly-sized in side dishes, were reasons for dissatisfaction of the students. The school lunch programs were blamed for its poor taste and lacks of variety and volume of the side dish which is mostly composed of kimchi, seasoned vegetables, and bulgogi. The most popular side dishes were pork- or fish cutlets, hams, and sausages while food with carrots, garlics or red peppers, vegetables like pumpkins, lotus roots, and seasoned vegetables were mostly disliked. It was concluded that the school lunch programs for middle- and high school students could be settled down by preparing with well-nourished food items that suits students' taste best and be served at right temperature.

  • This study was carried out to establish an effective marketing strategy based on Importance-Performance Analysis (IPA) of rice-convenience foods. IPA is one of the most efficient and simple methods to evaluate product quality. Data were collected from 652 people (320 males and 332 females) and analyzed by SPSS 19.0. Subjects consumed rice-convenience foods as a snack substitute (19.3%), breakfast (20.7%), lunch (37.4%), dinner (15.2%), and late-night meal (7.4%). The purpose for consumption of rice-convenience foods were as follows: light meal (34.8%), lack of time to prepare meal (42.2%), favorite restaurant is not nearby (2.3%), save money (3.4%), and outdoor activities (9.7%). All attributes about rice-convenience foods were categorized into intrinsic property and extrinsic property. As a result of factor analysis, health, sensibility, and diversity factors were extracted from intrinsic property. In addition, dependence and appearance factors were drawn from extrinsic property. In analyzing the differences between importance and performance, there were significant differences; 16 items in the intrinsic property (P<0.01), and 10 items in the extrinsic property (P<0.001). The IPA matrix is composed of four quadrants, and each represents different strategies; the first, 'keep up the good work', the second, 'possible overkill', the third, 'low priority for management', and the fourth, 'concentrate management'. As a result, factors of rice-convenience foods positioned in the fourth quadrant were 'safety (from food additives, etc.)' and 'price' in the intrinsic property and 'nutrition label' and 'safety of packaging material' in the extrinsic property. They need to be improved immediately. In this study, rice-convenience food factors for continuous maintenance and concentrative improvement were compared by IPA. Based upon the results of this study, it is necessary to develop methods to make efficient use of limited resources and practical marketing strategies.

  • This study was conducted to make on-site survey on the output pattern and utilization situation of 19 by-products selected, to evaluate their nutritional characteristics, to find out a reliable index with which digestion of by-products can be predicted on the basis of chemical compositions analyzed and to diagnose the risk of using book values in the absence of the actual values analyzed for diet formulation. Production and utilization situations of by-products were quite various. Nutritionally, fruit processing by-products such as apple pomace (AP), pear pomace (PP), grape pomace (GP), and persimmon peel (PSP), and bakery by-products (BB) were classified as energy feeds. Soybean curd meal (SCM), animal by- products such as blood (BD), feather meal (FM) and poultry by-products (PB), and activated milk processing sludge (AMS) were classified as protein feeds. Soy hulls (SH), spent mushroom compost (SMC), barley malt hulls (BMH), waste paper (WP) and broiler litter (BL) were classified as roughage. Rumen contents (RC) and restaurant food waste (FW) were nutritionally analogous to complete diets for cattle and swine, respectively. Compared to soybean meal (SBM), BD and FM contained high (P<0.05) levels of amino acids and barley malt sprouts (BMS), AMS and FW contained low (P<0.05) levels of amino acids. Enzymatic (pepsin) digestibilities of proteinaceous feeds ranged between 99 and 66%. In vitro DM digestibility was high (P<0.05) in the order of FW, BB, AP, SH, PP, PSP, BMH, BMS, SCM, GP, RC, PB, BL, WP, SMC, AMS, FM and BD. In vitro DM digestibility had the highest correlation (r=0.68) with nonfibrous carbohydrate among chemical components. Differences between analyzed values of chemical components and book values were considerable. Caution is required in using book values when large amount of by-products are used in diets.

  • Purpose: The aim of this study was to analyze the sodium contents of representative Korean foods high in sodium and develop them as a fundamental resource for setting the standard amount of sodium in foods. Methods: A total of 480 representative Korean foods high in sodium were collected from households, foodservice establishments, and restaurants in four regions (Capital region, Chungcheong & Gangwon Province, Gyeongsang province, and Jeolla province) and analyzed their sodium content. Results: The sodium content (per 100 g) of food categorized by food group was highest in kimchi and braised food (p < 0.001), and the sodium content of each food was highest in stir-fried anchovies (1,896.6 mg) followed by braised burdock and lotus roots (820.6 mg) and picked onions (809.3 mg) (p < 0.001). However, the sodium content per portion of food was highest in steamed short ribs (1,429.6 mg) from home meals (p < 0.001), Bibimbap, (1,074.1 mg) and steamed short ribs (838.8 mg) from foodservice (p < 0.001), spicy beef soup (3,273.2 mg), and pollack stew (2,930.2 mg) from restaurants (p < 0.001). The sodium content per 100 g and portion of soups and stews from restaurants was significantly higher than that of home meals and foodservice meals (p < 0.001), and the sodium content per portion of steam dishes and stir-fried dishes from home meals was significantly higher than that of foodservice meals (p < 0.05). Conclusions: These results suggest that developing and using low-sodium soybean sauces & soybean paste and kimchi is needed in an effort to reduce sodium intake. In addition, determination of the sodium contents of representative Korean foods known to be high in sodium is expected to be useful in establishing guidelines for reduction of sodium content.

  • The purpose of this paper is to verify improvement of the basic quality of food resources and make the pork legs as the more advanced food products after taking special processing steps with the mixture of traditional medical herbs and hot water extracted coffee meal. The pH level of the pettitoes(Jokbal) showed the highest rate among the control group but it showed no statistical differences in the moisture content between the control and the pettitoes(Jokbal) processed with coffee waste extract as an additional component. In addition, the levels of crude fat and crude ash showed slight increases as the addition of the amount increase. In case of the proteins, however, tendency of slight was decreased but it was not significantly difference as the amount increases. The sodium rate in the pettitoes(Jokbal) was higher in the additional group than in the control group. Texture analysis showed a tendency of wide decrease in the hardness and chewiness depending on amount of the added coffee waste extract. On the other hand, as for the cohesiveness and springiness, there was no significant difference with the control group. In case of the lightness value, as the amount of added coffee waste extract is increased from 10% to 20% and 30%, the 'L' value was reduced significantly compared to that of the control. And the 'a' value was not significantly different compared to the coffee waste extract foil impregnated furniture control. But the 'b' values were significantly increased in accordance with the result of increasing the amount of control is at the lowest level. The result may come from the influence of coffee waste extract, which affects the color of the pettitoes(Jokbal). According to the sensory evaluation, the pork part with 10% of coffee waste extract showed the highest score in looking, chewiness, smell and preference, resulting in the improvement in quality of the pettitoes(Jokbal).

  • The objectives of this study were to conduct preliminary research to investigate full course meals in Korean style restaurants in order: i) to analyze the nutrient contents of full course meals per servings, and ii ) by analyzing the above, to examine the amount and the quality of the foods served in the full course meals by two different types of Korean style restaurants. A total of 27 restaurants participated in this study, 7 restaurants from the luxurious hotels in Seoul and 20 restaurants from the City of Changwon. A key finding was that restaurant patrons tended to overconsume nutrients as compared to the Korean Recommended Daily Allowance (RDA), and restaurants generated large amounts of food wastes due to the excess food served. Other findings were as follows: 1) Compared with 1/3 or the Korean RDA, all the nutrients were oversupplied. The average nutrient ratios were about 3.7 times higher than 113 of the Korean RDA in calories, about 9 times higher in proteins, 10 times higher in phosphorus, 7 times higher in Vitamin Bl, and 12 times higher in Vitamin E. 2) Seventy-five percent (n = 20) of the restaurants served within the range of thirty to forty dishes, whereas most of the hotel restaurants (70%) served twenty dishes or fewer. 3) The average carbohydrate: protein: fat (CPF) ratio of caloric nutrients was 40:26 : 34. This study concluded that: i) Korean style full course meals provide too much food, nutrients, and calories, resulting in an over- or unbalanced nutrient intake, and ii ) the Korean style full course meals consisted of a high-protein, high-fat and high-caloric intake, which is similar to a westernized caloric nutrient pattern. Such over -or unbalanced nutrient intake could cause chronic degenerative problems such as cancer and cardiovascular disease. These findings indicate that restaurants serving Korean style full course meals should carefully plan their menus in order to provide their customers with balanced meals. They should also be strongly encouraged to play an active role in improving their customers' nutritional status, as well as reducing the restaurants wastage of food. Lastly, further research should be conducted to improve the quality of the menus in Korean restaurants. (Korean J Community Nutrition 8(3) : 327∼339, 2003)

  • This study was carried out with 436 college students in Chungnam to investigate the relationship between residences and eating patterns of college students. The subjects were devided into two groups; those who live in self-boarding house(SB) and home with parents(HWP). The results were as follows. An average height, weight and BMI were 173.5cm, 66.0kg and 21.9 in male SB and 161.8cm, 50.2kg and 19.2 in female SB and 172.9cm, 67.6kg and 22.6 in male HWP and 161.2cm, 50.9kg and 19.6 in female HWP, respectively. There were no significant differences in the general characteristics between the SB and the HWP. The proportions of disease possession, vitamin/mineral supplements and physical exercise were not significantly different between two groups by residences. Sleeping time of the SB was longer than that of the HWP. And, frequency of cigarette smoking and alcohol drinking of the SB were higher than those of the HWP. The proportions of skipping meals in the SB were higher than those in the HWP. Approximately 40.42% of the SB tended to skip the breakfast, while 11.26% of the HWP did. It turns out that the most common reason why skipped meals was due to a eating habit(44.21%) in the SB and a lack of time(48.85%) in the HWP, respectively. The survey shows that while a great majority of the SB had lunch at campus(50.00%) and home(30.00%), the HWP ate lunch at campus(33.79%) and restaurant(33.33%). About 48% of the SB ate out more than 2-3 times a week compared to 42% of the HWP. The daily intakes of calcium, iron, vitamin A, vitamin $B_2$, niacin and vitamin C in the SB were significantly higher than those in the HWP. The percent RDAs of calcium and iron intakes were lower in female students than in male students. In conclusions, students of self-boarding had more dietary problems than students of home with parents. These results suggest that college students of self-boarding might have low ability of meal management. Therefore, nutrition education for college students is needed, and menus of campus cafeterias should be developed to meet the various needs of students.
