A study was conducted to improve satisfaction to school food service and to furnish source materials for nutrient education by researching degree of satisfaction of middle school students to school food service. Following results are from the study that targeted 215 male students and 173 female students in 5 middle schools in Daegu. Satisfaction rates regarding taste of foods, smell, proper temperature, use of seasonal food, cafeteria atmosphere, numbers of side dishes, and kindness of the cook in a cafeteria were higher than dissatisfaction. And dissatisfaction rates were higher in quantity and quality of foods, sanitation, purity of table wares, opening to nutrient education and related informations for students, opinion reflection of students, food serving time and gratification to food serving than the opposite. But the degree of general satisfaction on school food service were higher than the degree of general dissatisfaction. Sanitation was the first thing to be changed in school food service, then quantity of food and taste for the last. And there were notable differences between male students and female students in sanitation satisfaction. The variables that influence on satisfaction to school food service were sanitary administration, numbers of side dishes, quantity of foods, nutrient, smell and taste when ranked. And the main three things that have similar rate in quantity with satisfaction rate are taste, smell and nutrient of school food service. Through these followed results, degree of general satisfactions to school food service were higher than degree of general dissatisfactions. But sanitation, quantity and quality of foods, taste, and food serving size were not satisfactory for students in rate. Therefore it has to be improved to enhance satisfactions to middle school food service.

The purpose of this study was to compare and analyze the assessment of salty taste and high-salt dietary behaviors of Korean university students and their Chinese counterparts. The researchers developed a taste assessment computer program focusing on preference for salty taste, and it was applied to 300 university students, including 100 Korean students, and 100 Chinese students in Daegu of South Korea, and 100 Chinese students in Shenyang of China (144 males and 156 females). The results of the taste assessment of Chinese and Korean university students are as follows. Among males, Koreans (36.0%), Chinese students in Korea (36.2%), and Chinese (40.4%) scored highest in the "a bit salty" followed by "normal." Among females, Koreans (36.0%), Chinese students in Korea (49.1%), and Chinese (28.3%) scored highest in the "normal". In terms of salt concentration in solution, among the male subjects, most Koreans favored the salt concentration of 0.31%, which is considered to be a "normal" concentration; most Chinese students in Korea favored 0.63%, which is considered to be "a bit salty", and most Chinese favored the concentration of 1.25%, which is considered to be "salty". As for the female subjects, Koreans, Chinese students studying abroad, and Chinese favored 0.31%, the "normal" level of concentration. Korean students scored higher than Chinese students in Korea and Chinese students both in males and females (p < 0.001, p < 0.01), in terms of high-salt dietary behaviors favored salty taste. This study suggests that Chinese university students need nutrition education in terms of modifying eating behaviors to reduce dietary salt intake.

The consumption of high-salt foods is an independent risk factor for increased hypertension. Thus, evaluating the relationship of taste sensitivity and pleasantness of high-salt foods such as Korean jang products, would help contribute to an understanding of salty food eating behaviors of the Korean rural elderly. This study aimed to verify the association between taste sensitivity and salinity of Korean jang products, and the preferences of food groups and nutrient intake in the rural elderly. We studied 269 elderly persons (males 83, females 186) aged above 65 years, residing in the rural area, Sunchang gun Jeonbuk. For each subject, a recognition threshold of 4 basic tastes and pleasant concentrations of NaCl were estimated using the sip- and-spit method. Taste preferences, frequency of intake of food groups, nutrient intakes, and salinity and sweetness of Korean jang products (Doenjang, Ganjang, Gochujang) were assessed. No association was found between salt taste recognition threshold and optimally preferred concentration of salt and salinity of Korean jang products. However, the sweet taste recognition threshold was positively related to the sweetness of Korean jang products. Also, the salinity of Doenjang positively correlated with the frequencies of food groups and nutrient intakes. That is to say that the sweet taste sensitivity was related to the sweetness of Korean jang products, but was not sensitive to the salty taste. The salinity of Doenjang correlated with the consumption of food and nutrient intakes. Taken together, these findings suggest the need for appropriate intervention and education to reduce the salinity of Doenjang, which is an important modifiable factor contributing to reducing sodium intake in the rural elderly.

Objectives: The purpose of this study was to analyze high-sugar food consumption habits frequency among elementary school students, and their correlations with eating habits and sweet taste assessment. Methods: The participants of the study were 164 elementary school students in Daegu, in the fifth or sixth grade, along with their parents. A questionnaire investigated eating habits, high-sugar food consumption habits and frequency, and sweet taste assessment. Results: The average eating habits score for elementary school students was determined to be 71.7 out of 100. Students with higher eating habits scores had lower high-sugar food consumption habits and frequency compared to those with lower eating habits scores. Sweet taste assessment revealed that students who preferred less sweetness chose a 5% sugar concentration, those with a preference for normal sweetness chose a 10% sugar concentration, and those who preferred sweeter tastes chose a 20% sugar concentration. Sweet taste assessment showed that students who tended to prefer less sweetness had the highest eating habits scores and the lowest scores for high-sugar food consumption habits and frequency. In addition, eating habits scores were found to be negatively correlated with high-sugar food consumption habits, high-sugar food consumption frequency, and sweet taste assessment. The sweet taste assessment was positively correlated with high-sugar food consumption habits and frequency. Conclusions: Our results indicate that students with good eating habits had more desirable overall sugar intake habits, and when the preference for sweetness was high, the frequency of high-sugar food consumption was also high. Our study highlights the importance of educating elementary school students and their parents about the harmful effects of excessive sugar consumption, as well as the benefits of adopting healthy eating habits and creating supportive environments.

The study results regarding the ingredient differences, sensory characteristics, purchasing type, usage and improvement direction for home-made traditional doenjang and factory produced commercial doenjang are as follows. The L-value indicates that home-made traditional doenjang has a higher value in average than the factory produce done, and the a-value indicates the opposite. Home-made traditional doenjang had higher water content than commercial doenjang ; however the pH values of commercial doenjang and home-made were 5.34 and 5.32 respectively, which was very similar. Factory produced commercial doenjang showed higher protein content than the home-made traditional doenjang. Regarding the correlation between ingredients, there was a significantly negative relationship between the L-value and a-value but a significantly positive relationship between the L-value and b-value. There were no significant relationship with water content, pH and protein content. For the color and taste, which are the sensory characteristics, commercial doenjang showed higher value than the traditional doenjang, but for smell, the values were similar. Regarding grittiness, the factory produced commercial doenjang had bigger particles than the traditional doenjang. Preference was a bit higher in the traditional doenjang. Of the 380 study subjects, most were from 40 to 49 years old (65.5%), and the most family type were nuclear families which was a total of 400 people (69%). Moreover, the most residential type was apartment which was 355people (61.2%), and for the monthly income, more than 2,510,000won was 48.3%. For the educational background, college education was 304 people (52.4%), and high school education was 199 people, 34.3%. In the usage, most of the people eat doenjang more than once a week, and usually their parents make the doenjang. People used both commercial doenjang and home-made traditional doenjang >home-made only >factory produced commercial doenjang only in that order. The reasons for using the home-made traditional doenjang aredelicate taste and flavor>more nutritious> anti-cancer ingredients in that order. The reason they use the factory produced commercial doenjang is because they don't know how to make it at home. The things that needed to be improved in the home-made traditional doenjang are bad smell> entire quality> flavor> color in order, indicating that studies for reducing bad smell are required. The things that needed to be improved in the factory produced commercial doenjang are taste & flavor> entire quality>bad smell> color in that order, indicating that people are more concern about it tasting like home-made than the smell. From the above results, we can see that better functional doenjang should be developed for family health and to increase the consumption of the doenjang, which has good functional psychological activities, also more various types of foods that use doenjang and scientific studies to reduce the home-made doenjang smell should be continuously studied. Moreover, studies on how to make the factory produced commercial doenjang taste more like traditional doenjang should be performed.

The purpose of this study was to investigate eating habits and dormitory foodservices' satisfaction in university students using dormitory foodservice in the Jeollabuk-do Iksan area. Self-administered questionnaires were completed by 195 students (86 male, 109 female). Many students (58.5%) ate less than two meals per day and spent around 30 min eating meals. The results show that snack and midnight meals were the main reasons (37.9%) for unhealthy eating habits. Main source of nutritional knowledge and information were TV and the Internet (58.5%), followed by friends and people (25.1%), nutrition books (10.3%), elective courses (4.6%), and newspapers and magazines (1.5%). Men had significantly higher satisfaction scores for nutrition, taste, diversity of menu, as well as hygiene of dormitory food court compared to women (p<0.05). Salty taste was the most important factor in evaluation of taste satisfaction, whereas sour taste was opposite. The reason for taste dissatisfaction in the dormitory food court was not salty enough, and it may be related with their eating habits. The results show that students need education for adequate knowledge and information about the relationship between health and nutrition.

With over 15,000 Thai restaurants worldwide and 5,342 in the USA alone, Thai cuisine has been repeatedly internationally acclaimed for its taste, flavors, smell, and nutritional values. The Thai Ministry of Commerce has also established a global objective to find and award the best Thai food restaurants using Thai Select Premium (TSP), Thai Select Unique (TSU), and Thai Select brand labels. Therefore, using systematic random sampling, 620 diners were selected from certified Thai Select restaurants (TSR) in either Los Angeles, New York, Miami, or Chicago to ask for their opinions concerning factors important to each restaurant's service loyalty (SL). The four constructs, 18 observed variables, and six hypotheses were analyzed using LISREL 9.1. Results revealed a significant positive effect (88% R²) on the causal factor interrelationships on TSRs' SL. Additionally, the three factors affecting SL the most were service tangibility, taste perceptions, and brand image, with total effect values of 0.94, 0.43, and 0.31, respectively. Finally, when each US diner was asked why they chose to eat Thai food, respondents overwhelmingly indicated that taste (49.50%) and healthiness (32.90%) were most important. The study also adds to the literature by highlighting the importance of Thai cuisine contributing to healthier lifestyles.

The present study investigated the perceptions of food adopted by Koreans using the characteristics of taste and nutrition. Two hundred and nine Korean subjects were surveyed including University students and adults from many diverse social backgrounds. The subjects sorted pictures of foods according to two conditions, how tasty and then how nutritions they thought the foods were using the Q-method. These pictures included two sets, one for individual food items and the second depicting typical Korean meals, yielding a total of four conditions, This methodology effectively addressed any language barrier as pictures and words in both Korean and English were used. It was an effective tool for allowing the identification of perceptual structures and indicating how prevalent they were across samples. The data were factor analysed and the resulting factor scores interpreted. Meat was regarded positively in all four conditions. Individual sweet foods were preferred by younger subjects while individual traditional foods were preferred by older subjects. Traditional Korean meals were also favoured while processed meals were not. Nutritionally, proteins were more valued than carbohydrates, fibre and vitamins. Meals that contained protein and were regarded as filling and sustaining were regarded positively. The implications for nutrition education were discussed.
