This study was conducted to evaluate the chemical hazards of 74 kinds of commercial anchovy fish sauce in Korea by measuring their biogenic amine content. The biogenic amines detected in commercial anchovy fish sauce were tryptamine, putrescine, cadaverine, tyramine, spermidine, spermine, and histamine. Among them, histamine content was the highest with an average of 1,439.62±812.62 mg/kg. Excessive intake of histamine could result in chemical food poisoning characterized by high blood pressure, headache, and diarrhea. Accordingly, by simulating histamine exposure (repetition=10,000 times) based on the daily intake of 0.969 g of domestic anchovy fish sauce, we found that the estimated average histamine exposure was 24.49±55.48 ㎍/kg bw/day and that the margins of exposure (MOE) value were 139.18 at 1% and 66,141.07 at 95% of 10,000 simulations (9,500 times). As such, it was confirmed that 9,500 out of 10,000 simulations of MOE analysis significantly exceeded MOE 10. Therefore, the risk of exposure to histamine from ingestion of commercial anchovy fish sauce is approximately very low.

The loquat (Eriobotrya japonica) is a plant belonging to the Rosaceae family, native to south-central China. It is cultivated in relatively warm areas such as Spain, Japan and South Korea. It is used commercially as an ornamental plant and for its yellow fruit, which contains much carotenoid, sugar and a little organic acid. In this study, chiffon cakes were prepared with the addition of 3%, 6%, 9% and 12% loquat fruit powder (LFP) in order to invest the mixing conditions. When more LFP was added to the dough, the pH level of the dough became lower. Specific gravity and viscosity of the dough significantly increased as higher amounts of LFP were added. In baked cakes, the weight and baking loss rate of LFP were not significantly different between samples, and the height of the risen test samples were lower than that of the controls. Moisture content was 33.58% in the 12% LFP sample (12% LFPS), which was the highest of all the samples. With respect to crust color, lightness, redness and, yellowness, these significantly decreased as the amount of LFP was increased, the 12% LFP being the lowest of all the samples. Lightness and yellowness of crumbs significantly decreased as the amount of LFP was increased, whereas redness showed the reverse effect. When looking at hardness and adhesiveness, the 12% LFPS was the highest of all the samples, nevertheless a difference in resilience was not significant among the samples. According to consumer perception, bitterness was significantly increased as amounts of LFP increased, however a difference in salty, astringency and oily tastes were not significant among the samples. The 12% LFPS showed the lowest score with respect to softness and overall acceptability. In conclusion, LFP could be considered a functional material, with the optimum amount of LFP for a chiffon cake of 3~9%.

BACKGROUND/OBJECTIVES: The concept of "food deserts" has been widely used in Western countries as a framework to identify areas with constrained access to fresh and nutritious foods, providing guidelines for targeted nutrition and public health programs. Unlike the vast amount of literature on food deserts in a Western context, only a few studies have addressed the concept in an East Asian context, and none of them have investigated spatial patterns of unhealthy food consumption from a South Korean perspective. SUBJECTS/METHODS: We first evaluated the applicability of food deserts in a Korean setting and identified four Korean-specific unhealthy food consumption indicators, including insufficient food consumption due to financial difficulty, limited consumption of fruits and vegetables, excessive consumption of junk food, and excessive consumption of instant noodles. The KNHANES 2008-2012 data in Seoul were analyzed with stratified sampling weights to understand the trends and basic characteristics of these eating patterns in each category. GIS analyses were then conducted for the data spatially aggregated at the sub-district level in order to create maps identifying areas of concern regarding each of these indicators and their combinations. RESULTS: Despite significant reduction in the rate of food insufficiency due to financial difficulty, the rates of excessive consumption of unhealthy foods (junk food and instant noodles) as well as limited consumption of fruits and vegetables have increased or remained high. These patterns tend to be found among relatively younger and more educated groups, regardless of income status. CONCLUSIONS: A GIS-based analysis demonstrated several hotspots as potential "food deserts" tailored to the Korean context based on the observed spatial patterns of undesirable food consumption. These findings could be used as a guide to prioritize areas for targeted intervention programs to facilitate healthy food consumption behaviors and thus improve nutrition and food-related health outcomes.

This study was conducted to investigate eating-out behavior patterns of youths, especially junior high and senior high school students. 1600 questionnaire surveys were distributed and 1487 were used for analysis. In order to consider regional differences as well as overall characteristics of youths' eating-out behaviors, the subjects were evenly sampled from north Seoul, south Seoul, big cities, middle/small cities and small towns. As for the frequency of eating-out, 62.7% of respondents answered once to twice per week. For the can of more than 5 times of eating-out per week, the respondents from south Seoul showed the highest frequency. For the case of no eating-out, the highest frequency was shown from the small towns. As for the most frequently visited place for eating-out, 33.6% of respondents answered Korean style restaurants, and 17.6% Boon-sik(Sanck-bar). Regarding the preference of Korean style restaurants, the highest rate was shown from the residents of big cities. For the question of when they eat out, 89.6% answered dinner and 6.3% lunch. For the question about reason of choosing particular restaurants, 61.5% of respondents referred to tastes and 16.6% price. For the question of the most important reason of eating out, 52.6% point out 'meal solution' and 25.6% 'for meeting.' As for the people accompanied when eating out, 67.2% of the respondents answered family. For the cost of eating out per person, 45.7% of the respondents spent 2000-4000 won for lunch; 31.1% spent 5000-10,000 won for dinner; 33.7% of the respondents spent more than 20,000 won for the special events. Regarding the regional differences of eating-out cost, respondents from south Seoul tended to spend the biggest amount of money for lunch, dinner and special day.

This study aims to identify the importance and satisfaction levels of home meals of high school students. A developed survey was conducted on July 10 through July 13, 2012. Of 12 high schools located in three different areas in South Korea, three high schools were singled out. For the analyses of the study, the following statistical methods were employed: frequency, cross-tabulation, independent sample t-test, one-way ANOVA, and Duncan as a post-hoc test. As a result, food experiences and education through home meals during childhood promote close ties with other family members and help them develop the food taste and preference that can naturally raise the meal satisfaction level by developing proper eating habit. More implications and discussion are suggested.

Feeding behavior of the Russet Sparrow Passer rutilans was studied in two different types of habitats, shelter belts and isolated forests, in south-eastern Hokkaido, Japan, during the breeding seasons of 1995 and 1996. Predominant foods were determined as Caterpillar, Coleoptera, Diptera, Ephemeropera, Odonate and some other insects. The composition of the nestiling foods were not the same by season, region, and year. Larger foods in size were used by birds in isolated forests more frequently than in shelter belts. Amount of food per feeding was significantly larger in isolated forests than in shelter belts. Although food supply were more abundant in isolated forests than in shelter belts, the feeding frequency did not significantly differ between these two habitats. The nest density was higher in isolated forests than in shelter belts. Results of this study indicate that when the feeding condition is poor, birds tend not show specific food selection behavior, the feeding range is therefore larger, and the feeding interval is longer. Contrarily, the birds show a specific food selection behavior when they are in good feeding condition, the feeding range is therefor smaller and the feeding interval decreases.

Purpose: By foreshadowing the historical background and cultural influence of Korean food and economic development in China, this paper demonstrates Chinese market entry strategies taken by TheBorn with its company history and CEO's background. Research design, data and methodology: The eclectic paradigm was utilized to analyze ownership, localization, and internalization advantages for TheBorn's first entry into the Chinese market. The research answers how TheBorn could expand its business in the early 2000s while most were skeptical about the globalization of Korean food. Results: First, possessing various restaurant franchises, food patents, and developments, and media use enabled to achieve a strong ownership advantage. Second, the Chinese market is conveniently located in South Korea. Thus, TheBorn could exercise direct management to its overseas restaurant to maintain the food quality and service. Lastly, establishing a sauce manufacturing plant and its branch company accelerated further expansions to other Chinese cities. Conclusions: Based on those success factors, TheBorn extended its business into different cities in China and emerged as a franchisor giant in the Korean restaurant franchise industry.
