  • Fat replacers are divided into three categories. These include carbohydrate-based, protein-based and fat-based replacers. Carbohydrate-based replacers occupy half of the fat replacers market. The main ingredients of carbohydrate-based are gums, starch, modified starch, cellulose and fiber. The functional properties of fat replacers are to retain moisture, to retard staling, to provide mouthfeel and texture, to emulsify, to stabilize emulsion, and to reduce fat. Using these functionalities, fat replacers are used in various foods such as baked goods, salad dressing, sauces, meat products, dairy products, frying foods, bakery, and confectionery. Success factors of fat replacers in the market are sensory equivalent, texture and safety as food ingredients.

  • This study was conducted to develop a salad dressing using jujube (Zizyphus jujuba Miller) puree and to evaluate the processing and quality characteristics of the salad dressing containing various amounts (0, 10, 20, 30, 40, and 50%) of jujube puree. Jujube puree was prepared by crushing peeled, deseeded and steamed fruit flesh. The dressing ingredients (jujube flesh puree, soy sauce, vinegar, oligosaccharide, olive oil, and water) were mixed, homogenized, and packaged in glass bottles. The quality characteristics (color property, total titratable acidity, soluble solids, viscosity, phenolic compound content, antioxidant activity, and sensory acceptability) of the dressing were analyzed. The lightness ($L^*$) and redness ($a^*$) of the dressing tended to increase as the amount of the jujube puree increased whereas the hue angle ($h^{\circ}$) decreased. The total titratable acidity, soluble solids, viscosity, phenolic compound content, and antioxidant activity of the dressing increased with the addition of more jujube puree. The sensory acceptability (color, smell, taste, texture, and overall acceptability) were significantly higher in the dressing added with 30% added jujube puree than in the other samples. The results show that jujube flesh puree (approximately 30%) can be utilized as an additive for preparing a dressing with simultaneously high antioxidant activity and acceptability.

  • Objectives: This investigation was carried out to explore the source and the mode of transmission of the diarrhea outbreak in Seongju-gun, Gyeongbuk, 2004 Methods: The authors conducted a questionnaire survey among the 275 persons (students, staff members and cooks) who ingested the possibly contaminated foods. We also investigated the drinking water and the dining facility, and we reviewed the process of cooking the salad, which was the presumed cause of the Enteropathogenic Escherichia coli(EPEC) diarrhea. The confirmed EPEC diarrheal case was defined as culture positive for EPEC, and the suspicious case was defined as diarrheal case with symptoms more than one of fever, vomiting and tenesmus. Results: The attack rate of EPEC diarrhea was 36.7%, and there were 8 confirmed cases. The possibility of the drinking being a source of the infection was very low, for chlorine was detected in all the drinking water via reviewing the past records and using a portable detector. The foods that were significantly associated with diarrhea were found. The relative risk (RR) for the lunch served Jul 7 was 4.12 (95% CI: 1.39-12.20). Among the non-boiled foods that were finally served, the RR for the salad was 1.66 (95% CI: 1.07-2.57). The cause of this outbreak was presumed to be the contaminated foods that were prepared by cooks using rubber glove with holes, and especially the salad and foods that were served sans boiling on Jul 7. Conclusions: Though this EPEC infection was not so clinically important, if a larger outbreak occurred, it might severely affect the public health. It is recommended to develop the more safe methods for cooking foods, and to strengthen the sanitary processing foods.

  • The purpose of this study was to provide the fundamental information for establishing the database needed to estimate total intakes of trans fatty acids in Korea. The amounts of trans fatty acids contained in 164 samples including 25 samples of margarines, 21 samples of shortenings, 19 samples of vegetable salad and cooking oils, 53 samples of confectionery products, 18 samples of bakery products, 19 samples of dairy products, and 9 samples of animal fats and meats were analyzed by capillary gas liquid chromatography. The average amounts of trans fatty acids in those foods were calculated and expressed as gram per one serving. Then, the average daily intakes of trans fatty acids per capita were estimated using the analyzed amounts of trans fatty acids and the amount of yearly production for those foods. The amounts of trans fatty acids per 100 g of lipids were $2.11{\sim}33.83%$ (14.66% on average) in margarines, $1.47{\sim}44.48%$ (14.21% on average) in shortenings, $0.18{\sim}3.82$ (1.54% on average) in vegetable salad and cooking oils, $0{\sim}45.81%$ (10.92% on average) in confectionery products, $0{\sim}18.32%$ (7.87% on average) in bakery products, $0.90{\sim}4.54%$ (2.27% on average) in dairy products, and $0.61{\sim}6.07%$ (2.24% on average) in animal fats and meats. Major isomers of trans fatty acid in the sample foods were $C_{18:1}$ and $C_{18:2}$. As a result, the korean average daily intake of trans fatty acids in korea was estimated to be 2.3 g per capita. The amounts of trans fatty acids consumed from each selected food were as follows: 0.35 g from margarines, 0.57 g from shortenings, 0.11 g from vegetable salad and cooking oils, 0.65 g from confectionery products, 0.07 g from bakery products, 0.14 g from dairy products and 0.21 g from animal fats and meats.

  • The purpose of this study was to distinguish which food is fast foods and to define the characteristics of fast foods. The 14 kind of foods(hamburger, pizza, fried chicken, raymyeon, hotdog, doughnut, fried fish cake, jajangmyeon udong, ice cream, dukbokki, spaghetti, sandwich, gimbab, and salad) and 5 characteristics of fast foods(takeout, franchise, fast serving, unhealthy, and cheap price foods) were selected based on the dictionary and previous research papers about fast foods for this study. A total of 306 male and female high school student in Daejeon area were participated. The data were gathered by questionnaire and analyzed by SPSS/WIN 18.0 program. The participants evaluated the fast foods as delicious and convenient foods but non-nutritious, i.e. high fat but vitamin deficient foods. Among the 14 foods examined, hamburger, pizza, and fried chicken were the foods which more than 90% of the participants acknowledged to fast foods. Dukbokki, spaghetti, sandwich, gimbab, and salad were the foods which less than 50% of the participant acknowledged to fast foods. Among the 5 characteristics of fast food examined, unhealthy foods showed the highest sensitivity, specificity, predictive value, and odds ratio(0.803, 0.712, 0.597, and 2.79, respectively), and cheap price showed the lowest values of those(0.565, 0.335, 0.242, and 0.85, respectively) for acknowledging foods to fast foods. As conclusion, hamburger, pizza, and fried chicken were the representative foods of fast foods. Fast foods are generally considered as fast served cheap price foods, but the participants did not think the fast foods as fast and cheap foods. The most distinguished characteristics of fast foods in the students' minds was unhealthy foods.

  • This study aims to analyze importance and performance factors on the quality of wellbeing fusion menu of fusion restaurants to provide helpful information for building up a detailed marketing strategy and present considerations for sales increase and more efficient business results. Importance on menu quality scored a higher level than performance on the whole in fusion restaurants. Notably, in regard to attributes of menu quality, it was found that respondents put higher stress on 'taste of food', 'sanitary of food', 'cleanliness of vessels', 'quality of menu' and 'freshness of food' than anything else. Wellbeing fusion menu which has an high intake frequency rate includes 'green vegetable noodles with black bean sauce', 'sweet pumpkin salad', 'salmon salad', and 'shrimp vegetable gratin' in that order. On the other hand, the intake frequencies of 'ovened green perilla gratin', 'pomegranate dressing tofu', 'bacon roll with glutinous rice powder', and 'pomegranate dressing bacon' were rated very low. In terms of the IPA analysis on wellbeing fusion menu quality, it was important to continuously maintain 'taste of food', 'sanitary of food', 'cleanliness of vessels', 'freshness of food', 'quality of menu', 'diet menu(low fat, low calories)', 'vegetable menu', 'nutrition of food', 'variety of menu' etc. Such items as 'price', 'distinction with existing food', and 'environment-friendly organic agriculture food material' are in need of intensive care and operation.
