A croquette added with heat-treated kimchi at 20% showing higher sensory preferences was analyzed for its physicochemical properties and antioxidant activity using a croquette without kimchi as a control. Compared with the control, kimchi-added croquette had 3.3-fold higher organic acids content (p<0.001), resulting in a significant reduction of pH (p<0.001) and higher metal chelating activity (p<0.001). Upon addition of kimchi, total reducing capacity increased from 109.4 to $139.4{\mu}g/g$ gallic acid equivalents (p<0.01), and DPPH radical scavenging activity also increased 2-fold, which corresponded to 54% of the electron-donating ability of 0.35 mM gallic acid. In addition, contents of free amino acids and ${\gamma}-aminobutyric$ acid (GABA) appreciably increased by 1.6-fold (p<0.01) and 10-fold (p<0.001), respectively. This could be attributed to the ingredients of kimchi and/or enzymatic transformation of precursors by microorganisms during kimchi fermentation. Kimchi-added croquette was determined to be a good source of dietary fiber relative to its calorie content. Texture profile analysis showed no significant differences in hardness, springiness, cohesiveness, gumminess, and chewiness between the two croquettes with or without kimchi. Taken together, this study shows that utilization of heat-treated kimchi as a filling for croquette could be a good strategy to improve both the nutritional quality and antioxidant activity of croquette.

We attempted to develop a seafood menu by applying the most preferred recipes to the most disliked seafood menus in order to improve elementary schoolers' seafood menu preferences and consumption levels. A survey was conducted on the attitudes of 106 fifth graders about nine cooking methods and 37 school seafood menus served in the past 2 years. The deep-frying method was the most preferred by both boys and girls. The next preferred methods by boys were grilling and batter-frying while those by girls were stir-frying and batter-frying. The most disliked menus were cold jellyfish salad, mussel soup, dried-pollack soup, and sea-snail salad in that order. Mussel soup, dried-pollack soup, and seasnails salad ranked as the least preferred menu as well. Finally, standardized recipes for mussel croquette, dried-pollack Gangjeong, and batter-fried seasnails were developed. Consumption ratios of mussel croquette (85.94%), dried-pollack Gangjeong (79.55%), and batter-fried seasnails (75.5%) were significantly improved compared to the original menu (p<0.001). For mussel croquette, satisfaction scores for serving size, appearance, flavor, texture, and taste were significantly higher, and intakes of protein, phosphorus, iron, potassium, vitamin A, vitamin B1, vitamin B2, niacin, and vitamin C were significantly improved, as compared with mussel soup (p<0.001). Dried-pollack Gangjeong, texture and taste scores were significantly improved compared to dried-pollack soup. For batter-fried seasnails, protein, phosphorus, and iron intake levels and taste score were significantly improved compared to seasnail salad. Findings of the study suggest that a combination of disliked seafood ingredients and preferred recipes may be helpful in improving elementary school foodservice by increasing menu preference and consumption ratio.

The purpose of this study was to investigate the perception and preference for Korean Kimchi in Singapore. A questionnaire was answered by both male 236(43.0%) and female 313(57.0%) college students residing in Singapore. The results were as follows : the nationality of Kimchi as Korean was given by 86.9% of the participants, and 48.7% had eaten Kimchi. For their perceptions on Kimchi, the highest answer at a mean of 3.95 was 'Kimchi is a good side dish with cooked rice'. It was significantly different than 'Kimchi is delicious'(M=3.14, p<.05). In the evaluation of different kinds of Kimchi, taste was highest for anchovy dachi Kimchi(M=5.50) on the fourth day of fermentations, and overall acceptability was also highest for the anchovy dachi Kimchi(M=6.18) on the fourth day(p<.001). In the sensory evaluation by Kimchi use, the best taste was in the order of Kimchi Salad(M=6.10), Kimchi Bacon Roll(M=6.00) and Kimchi Croquette(M=5.67), and the order for overall acceptability was Kimchi Salad(M=6.10), Kimchi Bacon Roll(M=6.00) and Kimchi Croquette(M=5.92).

Studies have shown that the preference and average consumption of kimchi among youths have been decreasing partly due to the westernization of the diet. In this study, we examined kimchi consumption status and the annual utilization of 29 kimchi menus registered in the National Education Information System (NEIS) among the students, and then developed seven kimchi menus based on the preference tests and plate waste analysis. Our findings showed that average kimchi consumption by second and fifth graders during lunch time was 19.3% and 17.3%, respectively, of the recommendation (40 g per meal) in the 2010 KDRI. Incidentally, more than 75% of elementary school dieticians answered that ten kimchi menus (31%) registered in the NEIS were never chosen by them in the previous year. The least adopted types of kimchi menu included cooked rice, porridge, stew, pancake, deep-fry and grill. The newly developed kimchi menus included kimchi sauce tofu deopbap, kimchi bacon rice ball, kimchi chicken potato stew, kimchi vegetable fried noodles, kimchi meatballs, kimchi cheese croquette and kimchi potato salad. All these kimchi food items contained 10~20 g of kimchi per serving, and the standardized recipes and nutrient analysis were provided. Kimchi cheese croquette was most liked by fourth graders followed by kimchi sauce tofu deopbap, kimchi meatball and kimchi chicken potato stew in that order. These four menus were again evaluated among second and fifth graders. The kimchi meatballs were most preferred among these groups of students with no leftover but kimchi sauce tofu deopbap was least favorable, producing 17.1% of plate waste. Finally, kimchi cheese croquette and kimchi potato salad were given the highest and lowest scores, respectively, by 87 school dieticians. The findings of this study suggest that efforts on the development of kimchi menu for school food services may help to promote a preference and consumption of kimchi among elementary school students.

This study is basic research focused on product development and market activation based on analysis of current usage and demand for development of processed blue crabs. A total of 556 subjects aged 20s to 60s living in the Seoul area were surveyed. According to the survey, 65.1% of subjects consumed blue crabs at home, and 82% of them purchased blue crabs whole and undressed. Respondents gave higher marks to taste, nutrition, and texture compared to ingredient preparation, eating method, and price. Majority of blue crab consumers had no experiences of consuming processed blue crabs. Exactly 57.0% of consumers purchased them at big shopping centers, and the reason for purchasing was their good taste. When female consumers purchased processed blue crabs, they checked every part carefully compared to male consumers. Women gave high scores to blue crab powder, blue crab extract, blue crab croquette, and blue crab cake compared to men, demonstrating the necessity of developing processed blue crabs. Furthermore, the experienced processed blue crab group recognized the necessity of developing processed blue crabs compared to the inexperienced group. People showed significant differences in purchasing processed blue crabs according to gender as well as previous experience of blue crab consumption.

The purpose of this study was to investigate food preferences and dietary habits of university students in Kyungbuk province. We assessed anthropometric measurements, food preferences, and dietary habits of seventy nine male and sixty nine female students at K university. The results of this study were analyzed with $\chi$$^2$, t, and ANOVA test using SPSS package program. The percentages of students who were underweight, normal and overweight by body mass index (BMI) were 18.0, 22.1, and 27.7 for males, and 17.8, 21.7, and 28.7 for females, respectively. Preferences for noodles with bean sauce, bread (castella, red-bean bread), beef, pork, chicken, ham, garlic, milk soy bean milt carbonated drink ionic beverages, bun (fried, steamed), croquette, soju(alcohol) and tobacco were higher in males than females, but preferences for tangle, strawberry and orange were lower in males than females. Males did not skip meals compared to females, and ate more meat fat than females. Males exercised more frequently and longer than females. Eighty six point eight percent of females and 69.7% of males were dissatisfied with their weights, and females attempted the weight control more than males. Preferences for bibimbab(boiled rice with assorted mixtures), ionic beverages, and beer were shown higher in overweight males than in normal ones and preference for red fish, hamburger, and chocolate were higher in underweight females than overweight ones. Overweight females skipped meals more and ate more meat fats than normal weight ones. Normal weight males and underweight females were satisfied with their weight. The results of this study suggest that university students need more nutritional education, and modification of dietary habits based on food preference to prevent and treat obesity and to maintain their health.

Acrolein is a highly toxic, reactive mutagenic aldehyde. Humans are exposed to acrolein vapors from overheated cooking oil, cigarette smoke, and combustion of organic products. In this study, we investigated elementary and middle school students' consumption of foods cooked at high heat, such as fried, direct fire, and indirect fire cooked foods. The subjects of this survey study were 265 fifth grade students and 396 middle school students nationwide. According to the results of the frequency test, broiled fish was the most frequently consumed, followed by fried fish, indirect cooked samgyebsal, and other fried foods, which were eaten more than three times per month. The total intake of foods cooked at high heat per child over 1 year was in the following order: Fried chicken(7.50 kg) > Samgeybsal(6.57 kg) > Broiled pork ribs(4.18 kg) > Broiled fish(4.12 kg) > Bulgogi(3.31 kg) > Fried dish(3.18 kg) > Pork cuttlet(3.17 kg) > Jeyukbockeum(3.13 kg) > Charcoal-broiled beef ribs(2.74 kg) > Roasted whole chicken(2.05 kg) > Dackochi(1.87 kg) > Tangsuyuk(1.87 kg) > Fried fish(1.83 kg) > Hamburger patties(1.21 kg) > Fried potato(1.01 kg) > Barbecue(0.95 kg) > Doughnut(0.80 kg) > Corn dog(0.66 kg) > Croquette(0.51 kg). The favorite cooking method was indirect fire cooking for beef, pork, and fish, whereas frying was preferred for chicken. The results of this study provide important data for assessment of acrolein exposure via foods cooked at high heat temperature. The results also indicate that children might be exposed to acrolein through consumption of foods cooked at high heat temperature, suggesting the need to promote education of proper food consumption behavior.
