This study aimed to examine the health-related lifestyle habits and eating behaviors according to gender, ethnicity, and residence type of university students in Yanbian, China. Self-administered questionnaires were collected from 302 university students. Of the male students, 12.1% and 42.0% were in the underweight and overweight groups, respectively, and of the female subjects, 21.3% and 16.3%, were in those respective groups. More male than female students preferred the overweight body somatotype. In contrast, about 49.4% of female students were hoping to be underweight, and female students had more obvious difficulties with body somatotype perception, whereas their exercise frequency and time spent exercising per day were much less than those of male students. More Chinese than Korean-Chinese subjects exhibited regular eating habits, which included eating at the same time everyday and at the same frequency per day; these habits were, accompanied by generally healthier lifestyle habits regarding regularity of activity and exercise time. Self-boarding students had a significantly higher BMI ($23.7{\pm}5.1kg/m^2$) and were more likely to be overweight (43.5%) as compared to students who lived in a dormitory or with family. Salty taste was preferred by Chinese students more than Korean-Chinese students, and greasy taste was preferred by Korean-Chinese students as compared with Chinese students. This study found that inherent and environmental factors are related with the dietary behaviors of university students in Yanbian, China. Further studies are required to elucidate the structural elements of family life and the sociocultural factors associated with dietary behaviors in Yanbian.

Korean Food Globalization has been launched as a tool of civil ambassador and the high value-oriented industry. According to department of statistics in 2012, the trend of Korean food globalization from international visitors of Chinese and Japanese has grown. Hence, this study is purposed to identify the level of satisfaction of Chinese and Japanese consumers based on their food-related lifestyle. The survey was conducted by interviewing 403 Chinese and Japanese visitors who have experienced Korean food. The survey questionnaire was composed of 3 parts of demographic information, food-related lifestyle, and satisfaction of Korean restaurant. As factor analysis results, 3 factors were yielded for the food-related lifestyle factors-a eat-out preferred group, a health preferred group, and a taste preferred group, and 3 factors were generated for Korean restaurant satisfaction-hygiene and service, menu, and food quality. For cluster analysis, 3 clusters were identified as follows: high interested in food itself, health interested, and taste interested. Female appears to be significantly different in terms of 3 clusters than male. Nationality shows that Chinese consumers showed a high interest in food itself whereas Japanese consumers were high interested in health. With regard to Korean restaurant satisfaction, service appeared to be important in Chinese consumers while Japanese consumers showed a higher mean value on serving size, price, and nutrition. The findings concluded that by understanding the nature of food-related lifestyle of international visitors, marketing strategies can better meet visitors' expectations and increase their satisfaction with Korean restaurants.

The purpose of this study was to survey the perception and preference for Korean food among Chinese students residing in Korea (Chinese foreign students, N=69) and China (Chinese-locals, N=98). A total of 76.8% of Chinese foreign students and 70.4% of Chinese-locals had ever eaten Korean food in China before visiting Korea, and motivation to try Korean food at first was 'easy access to Korean food restaurants' (Chinese foreign students 38.6%, Chinese-locals 44.9%). The most important factors in selecting Korean food were 'taste' and 'price' (Chinese foreign students 72.7% and 18.2%, Chinese-locals 59.1% and 22.7%, respectively), and needed improvements for Korean food were 'spicy and salty taste' and 'nutritional aspect' (Chinese foreign students 54.5% and 25.8%, Chinese-locals 33.3% and 36.4%, p<0.05). The scores for perception of Korean food were significantly lower in Chinese-locals (2.99) than in Chinese foreign students (3.31)(p<0.001). Chinese foreign students preferred Bulgogi (20.5%), Neobiani (20.1%), and Galbijjim (17.9%), whereas Chinese-locals preferred Bulgogi (16.1%), Gimbap (16.1%), and Samgyetang (15.2%) (p<0.001). The most preferred condiment was 'Garlic' (18.0%) in Chinese foreign students, and 'Red pepper powder' (16.4%) in Chinese-locals. The results of the study can be used as a foundation to prepare a globalization strategy for Korean Food.

The of this study was to the abilities of Northeast Asians to discriminate sweetness on foods and their preference sweetness. Panels of Korean, Japanese and Chinese three sample -sucrose solutions, bulgogi, julienned radish salad- in which the sucrose levels had been manipulated to produce five samples of each. The sucrose solutions were prepared 1%, 3%, 5%, 7%, 9% sucrose to the water. Bulgogi and julienned radish salad 3%, 9%, 15%, 21%, 27% sucrose to the recipe. As, the three ethnic groups significant differences in test of sweetness in sucrose solutions(79%). Korean(a=1.164) to be the most sweetness, compared to Japanese(a=1.063) and Chinese(a=0.999). All ethnic groups preferred $3{\sim}7%$ solution, and Korean than Japanese and Chinese. Ethnic groups significant differences in sweetness of the julienned radish salad 21% sucrose. Korean(a=1.054) appeared to be the most able to detect the sweetness, compared to their Japanese(a=0.785) and Chinese(a=0.642). Both Korean and Japanese the strongest preference for the 15% julienned radish salad, the Chinese preferred the 21%. The abilities of ethnic groups to detect the sweetness in bulgogi significant differences high concentration(more than 27%), and the result of regression analysis on the awareness of sweet taste order Korean(a=0.918), Japanese(a=0.832), Chinese(a=0.690). All groups preferred the $9{\sim}21%$ bulgogi the most, Japanese showed higher preference 15% bulgogi than did Korean and Chinese.

In this study, we compared the quality and sensory characteristics of 4 types of fresh tomatoes and 2 types of canned tomatoes, and then determined the most preferred quality characteristics and tomato type for the production of tomato sauce. The sample tomatoes were prepared by cutting after either peeling or heating for 5 min. Soluble solids were in the following order: Italian canned >American canned, Cherry> Vita king > Aranka > general tomatoes. The primary free sugars were fructose and glucose, and we determined that fructose and glucose were the most prevalent sugars in the cherry and American canned tomatoes. The total sugars, which were the sum of the fructose and glucose contents, were consistent with the soluble solid contents. pH was measured in the following order: general> Italian canned> Cherry, Vitaking> Aranka> American canned tomatoes. The most abundant amino acid was glutamic acid, and its content in the unheated tomatoes occurred in the following order: American canned> Italian canned> Vita king> Cherry> general tomatoes; however, after heating, the Vita king tomato was followed by the American canned tomato. The lightness (L value) of the fresh tomatoes tended to be higher than that of the canned tomatoes, and it decreased after heating. The redness (a value) of the unheated tomatoes was in the following order: Italian canned> American canned> Vitaking tomatoes; after heating, the Vitaking evidenced the highest values, followed by the canned tomatoes. The result of our QDA profile of sensory characteristics according to redness, aroma, sweet taste, sour taste, palatability, and viscosity was in the following order: Italian canned > American canned > Vitaking tomatoes, which evidenced the most balanced hexagonal shape. In the preference test, 2 types of canned tomatoes and Vitaking tomatoes were the most preferred among the fresh tomatoes. From the correlation coefficients among the sensory characteristics, canned tomatoes were the most preferred for the production of tomato sauce due to its high redness, flavor, palatability, and viscosity values. Vitaking tomatoes were the most appropriate among the fresh tomatoes.

This study was performed to investigate the preference and consumption pattern on milk and milk products of middle and high school students. The subjects were 1,195 students(590 middle school and 605 high school students) living in Geochang area. The survey was conducted by using a self-administered questionnaire in November, 2004. The results were as follows. Sixty-three point four percent of the subjects liked milk, and the main reason was 'accelerate growth and development'(55.4%). Preferred tastes of milk were 'savory taste'(35.4%) and 'sweet taste' (29.9%). Banana milk, chocolate milk, strawberry milk, ice cream, yoplait and yogurt were highly preferred. General preference for different kinds of milk was significantly higher in high school students and male students than in middle school students and female ones. With regard to preference for dairy products, cream (p<0.01) and butter(p<0.05) was preferred more by male students than by female ones, ice cream(p<0.05), yoplait (p<0.05) more by female students than male ones. The score of milk intake frequency was 3.84(3-4 times a week) out of 5 points(7 times a week) for white milk, and that of chocolate milk was 1.98, banana milk 1.96, strawberry milk 1.72, coffee milk 1.65, showing that these products were drank less then once a week. In addition, the white milk intake frequency was significantly higher in middle school students and male students than in high school students and female students(p<0.001). Preference for milk showed a positive correlation with preference for dairy products (r=0.543, P<0.001) and frequency of milk intake(r=0.429, P<0.001). This suggests that those who prefer milk high tend to prefer dairy products and to show high milk intake frequency. In addition, milk intake frequency was in a high positive correlation with dairy product intake frequency(r=0.648, P<0.001).

This research was conducted to examine the awareness and preference levels related to MSG (monosodium glutamate) according to well-being dietary life pursuit attitude factors as well as to improve opportunities to meet value conscious consumption of well-being-oriented customers. According to well-being dietary life pursuit attitude factors, respondents were divided to three clusters, indifference type, well-being-oriented type, and active health action type. Sensory evaluations were carried out on soybean paste soup (Doenjang-guk) and seasoned spinach with different levels of MSG. In the results, 74.4% of all respondents preferred Doenjang soup with 2% MSG, 65.4% preferred seasoned spinach with the same ratio of MSG, and 35.9% preferred seasoned spinach with 0.5% MSG. Regarding the acceptance level of MSG, addition of MSG to improve taste was acceptable to the indifference type (cluster 1). On the contrary, active health action type did not prefer MSG, wanted natural seasonings despite high prices, and preferred to dine at restaurants that serve MSG-free foods. Based on this study, restaurant companies should segment their customers on the basis of MSG usage and establish their positioning strategies according to their concepts.

Haliotis discus, a useful abalone of herbivorous gastropod, shows feeding preference to marine algae depending upon their growth stage and recognition of taste. This study was carried out to investigate this abalone's algal preferences and the presence of feeding stimulants. In single-choice experiments the small (S) group generally preferred Ulva pertusa (Chlorophyta), whereas the medium (M) and large (L) group preferred both Laminaria japonica (Phaeophyta) and Undaria pinnatifida (Phaeophyta). In multi-choice experiments using 4 algal species of L. japonica, U. pertusa, U. pinnatifida and Ecklonia cava (Phaeophyta), the results were same as in the single-choice experiments; the S group preferred U. pertusa the most, while the M and L group preferred both U. pinnatifida and L. japonica. However E. cava was not preferred by any groups. In order to examine the presence of feeding stimulant, chemical compounds from algae used as feed were isolated and identified. The abalone responded to water soluble matters of L. japonica, U. pinnatifida and U. pertusa, but those of E. cava and Sargassum sagamianum (Phaeophyta) were not attractive to them. In feeding stimulant experiments using fat soluble matters, the S group preferred the fat soluble matter of U. pertusa the most, while the M group and the L group preferred those of U. pertusa and U. pinnatifida, and those of L. japonica, respectively. However the fat soluble matter of S. sagamianum was not attractive to the abalone. The results of feeding stimulant experiments were same as those of single-choice or multi-choice experiments, which showed that compound lipids in fat soluble matter might act as feeding-stimulant.
