  • Transgenic mouse models have been introduced and accepted by regulatory bodies as an alternative to carcinogenicity assay models to predict and evaluate chemical carcinogens. The recent research outcomes in transgenic mouse models have made progressive advances in the understanding of chemical carcinogenesis and the evaluation of potential human carcinogens. However, these models still remain to be insufficient assay systems although the insufficiencies have been recognised and are being resolved. Based on up to date information from literature, this review article intends to understand currently accepted transgenic mouse models, issues arising from study design, interpretation of the study, results of validation project and their cancer prediction rate, and further perspectives of cancer assay models from the regulatory view point.

  • BACKGROUND/OBJECTIVES: The purpose of this study was to measure consumer acceptance of edible insect foods (EIFs) while applying the extended theory of planned behavior (ETPB). Insects as food have attracted interest as potential possible sources of nutrition for the future. This study investigated consumers' perception toward insect food and future purchase behaviors. SUBJECTS/METHODS: A survey was conducted among citizens of Korea. About two thirds of respondents had tried an EIF previously, and the mean value for food neophobia was 3.1 on a 5-point Likert scale. Respondents were divided into 2 groups of those experienced with EIFs and those not and by level of food neophobia. An independent t-test, multiple regression and descriptive analyses were conducted on the data. RESULTS: The primary reason for not eating EIFs was that their insect form induced disgust. Comparisons of ETPB attributes by experience with EIFs showed significant differences between groups for food neophobia, subjective norm, attitude, and behavioral intention. In addition, significant differences were found for subjective norm, perceived behavioral control, attitude, and behavioral intention between 2 neophobia groups. Finally, the results of measuring the relationships between ETPB attributes and behavioral intention showed only subjective norm and attitude affected behavioral intention. CONCLUSIONS: These results suggest that enhanced subjective norms producing a publicly accepted EIFs environment would help encourage the purchase of EIFs. The results of this study can help the development of EIF products for future food markets.

  • Diet is generally accepted as one of the important factors in human cancer development. Ethyl carbamate has been associated with cancer for several decades and mainly found in the fermented beverages and foodstuff. The relationship between ethyl carbamate and the human health cannot be ignored especially in the areas where fermented foods consists of regular food consumption. To investigate the ethyl carbamate exposure level in Korean population, commercial fermented food samples were collected form local markets I Seoul area and home-made varieties were collected throughout the country. Following partial purification the concentration of ethyl carbamete was determined by GC/ MS. The concentration of ethyl carbamate ranged to 70 ppb in soysauce, to 10 ppb in soybean paste, and to 5 ppb in vinegars. Korean traditional alcoholic beverages showed small amount of ethyl carbamate. The estimated daily exposure of Korean population was 0~1900ng/day. It would be prudent to put efforts to minimize the formation of ethyl carbamate since the risk from the higher range exposure cannot be ignored.

  • This paper attempts to examine the degree of chef's satisfaction on food purchasing in 5-star hotel in Seoul. Nowadays, hotel industry in Korea is becoming more and more competitive and the hotel products higher education. Among a range of divisions in deluxe hotel in Seoul, in particular, a F&B division has been more profitable than the others. It is widely accepted that the proportion of revenue obtained from F&B sales is higher than that of revenue from room sales. However, under the IMF intervention, hotels in Korea trend to depend on room sales rather than F&B sales in terms of profit. In such a environment, it is essential that F&B division should carefully seek for an appropriate purchasing procedure which will affect an organizational structure and allow the company to fulfill its goals. Moreover, it is timely their performance and quality of services through ideal food purchasing procedure. In this paper, the author uses a survey technique distributed to approximately 200 chefs who work at 5-stars hotel in Seoul. The author expects that this paper will contribute to the researchers or practitioners who might need a reference on the food purchasing system.

  • In this study, the food cost for the urban worker's living expenses was estimated for the Korea Labor Union. The urban workers living expenses are minimum of healthy and decency level expenses with allowances for minimum quality of life. Thus, the food cost should be enough for purchasing proper kinds and amount of foods which can supply sufficient nutrient to maintain health and which should reflect current food consumption patterns. To estimate the food cost, the Korean Recommended Dietary Allowances was used to calculate the amount of nutrients which should be supplied. The National nutrition survey and the Food balance sheet, were used to estimate the current consumption patterns for the kind and amount of food. To estimate price for each food item, the market survey was executed in six large cities. Also, to verify the estimated food cost, actual food costs were surveyed. For 5 kinds of model household, dietary allowances were calculated for the each nutrient. Using the Korean food guides, the number of serving for each food group were decided for the model households. In each food group, the amount and kind of foods were decided by the current food consumption pattern. The kind and amount of food were adjusted by the amount of calculated nutrient. When the amount of nutrient was between 90% and 110% of the recommended dietary intake, it was accepted. With these amount and kinds of foods, the food cost were calculated using the market survey. Considering extra expenses for the eating-out and processed foods, extra expenses are added. As a results, for single person family, the estimated food cost was 149,210won per month. For two, three, four and five person family, the estimated food costs were 245,179won, 381,182won, 501,669won and 687,980won per month, respectively. The estimated food cost were lower in the single and two person family than the actual food cost by the survey. The cost for eating-out gave major differences. In the future, to estimate food cost, the food consumption patterns for the different kind of household, sex and age should be studied carefully. Also, the pattern of eating-out should by analyzed.

  • In this study, we compared the differences and similarities between the Korean food culture and the Vietnamese food culture by surveying food resources and researching the process of Korean food being accepted into Vietnam. We suggest countermeasures for advancing Korean food into Vietnam. We conducted in-depth interviews regarding Korean food with Vietnamese food specialists who ate Korean food. As a result, Vietnamese foodies eagerly recognized that the most representative thing about Korean food was the special properties of its various and affluent side dishes. They were also aware of kimchi, made of various vegetables and condiments, as an excellent side dish compared to the Vietnamese who's staple is boiled rice. Furthermore, the flavor of Korean food was preferred by the Vietnamese who were familiar with foods such as Neue-ok-mom or fermented seafood. It was thought that the new food could be eaten with many vegetables. The specialists replied that the most typical functional property of Korean food was health. The acceptance process of Korean food into Vietnam was based on the acculturation theory. That made the Vietnamese easily experienced strange culture in the case of propagation by whom have already experienced, through the selective filter steps by various images of Korea, and made them accept the Korean food through temporary choose and acceptance step such as recommendations by friends. Globalization strategies for Korean food proposed by the Vietnamese foodies were public relations marketing in voluntary contact environments, distinguishing traditional Korean foods through research and development, and globalization by diversifying the Korean restaurant concept.

  • It is widely accepted that free-radical induced oxidative damages are involved in pathogenic processes of major diseases including cancer, atherosclerosis, rheumatoid arthritis and diabetes. A number of epidemiological studies have indicated that frequent consumptions of plant foods rich in antioxidants reduce the risk of developing cancer and cardiovascular diseases, while many intervention trials have failed to prove the protective role of major dietary antioxidants.(omitted)

  • The cooking characteristics of Hicook with lecithin and GMS as emulsifier were examined for effect on the reduction of oil levels in fried foods. Hicook and soybean oil were used in stir-frying and pan-frying, and in case of Hicook the weight of oil absorbed and spattered during cooking were significantly lower than in case of soybean oil. Next this study attempt to standardize the recipe for preparation of selected Korean foods, especially in regards of the amount of oil used during cooking. The foods studied were all used frequently in Korea, they inculded stir-fried vegetables, stir-fried rice, and pan-fried fish and soybean curd. The results showed that Hicook, even in a half amount, made it possible cooking food with good properties, and calorie content of cooked foods could be lowered considerably. The trained panelists evaluated sensory characteristics of foods, flavor, appearance, and overall acceptability. Sensory qualities of food prepared with Hicook were highly acceptable, and rated better than controls in flavor and overall acceptability. But because stir-fried food was accepted greasy and oily in customarily, the appearance was rated lower than comtrol. In summary, application of hicook offers means of lowering fat levels while keeping sensory quality good. The emulsifier in Hicook is responsible for reduction of oil content and improvement of quality of fried foods.

  • Purpose - This research aims to explore factors that could facilitate and/or impede consumers' long-term goal-relevant food consumption, in the pursuit of a long-term goal. Research Design, Data, and Methodology - The main experiment's sample comprised 289 female students at C University. The structural equation model of the Amos 18.0 program was used to verify the hypotheses. Results - Hypotheses concerning positive effects of long-term goal commitment and expectancy of long-term goal attainment, and negative effects of pleasure-seeking needs on long-term goal-relevant food consumption behaviors were accepted. Furthermore, self-efficacy's positive effects on long-term goal commitment and expectancy of long-term goal attainment, and negative effects on the strength of pleasure-seeking were explored. Appearance self-esteem negatively affected long-term goal commitment. Conclusions - Individuals' self-efficacy positively affects long-term goal commitment and expectancy of long-term goal attainment, and significantly weakens the need to seek pleasure in food consumption behaviors. Appearance self-esteem negatively affects long-term goal commitment. Both long-term goal commitment and expectancy of long-term goal attainment significantly positively influence long-term goal-relevant food consumption behaviors. However, those heavily needing pleasure-seeking are less likely to engage in such behaviors.
