        Although probiotics have been shown to improve health when consumed, recent studies have reported that they can cause unwanted side effects due to bacterial-human interactions. Therefore, the importance of prebiotics that can form beneficial microbiome in the gut has been emphasized. This study isolated and identified bacteria capable of producing biopoymer as a candidate prebiotic from traditional fermented foods. The isolated and identified strain was named WCYSK01 (Wissella sp. strain YSK01). The composition of the medium for culturing this strain was prepared by dissolving 3 g K2HPO4, 0.2 g MgSO4, 0.05 g CaCl2, 0.1 g NaCl in 1 L of distilled water. The LMBP(low molecular weight biopoymers) produced when fermentation was performed with sucrose and maltose as substrates were mainly consisted of DP3 (degree of polymer; isomaltotriose), DP4 (isomaltotetraose), DP5 (isomaltopentaose), and DP6 (isomaltoheptaose). The optimization of LMBP (low molecular weight of biopolymer) production was performed using the response surface methodology. The fermentation process temperature range of 18 to 32oC, the fermentation medium pH in the range of 5.1 to 7.9. The yield of LMBP production by the strain was found to be significantly affected by q fermentation temperature and pH. The optimal fermentation conditions were found at the normal point, and the production yield was more than 75% at pH 7.5 and temperature of 23oC.

        To enumerate Staphylococcus aureus in food, Baird-Parker Agar (BPA) is usually used in the conventional method, However it requires time and space for the preparation and plating, and incubation. Thus, use of the 3MTM PetrifilmTM Staph Express Count Plate (STX Petrifilm) might be appropriate to solve these challenging problems. The purpose of this study was to compare the efficiency of STX Petrifilm with BPA for enumeration of S. aureus in various foods. A mixture of S. aureus strains ATCC29213, ATCC25923, and ATCC13565 was inoculated on marinated pork chop, beef (chuck tender), dried filefish, semi-dried squid, rice cake, and Japchae (stir-fried glass noodles) at 2, 3, 5, and 7 Log CFU/g. S. aureus cell counts were enumerated by spread-plating on STX Petrifilm and BPA after 0 and 24 hours at 4oC (marinated pork chop, beef, semi-dried squid, and stir-fried glass noodles) and 25oC (dried filefish and rice cake). Recovery of STX Petrifilm for S. aureus from various food samples was compared with BPA, and the results showed that there were no significant differences between two selective media in all cases. The results indicated that STX Petrifilm had enough efficiency to recover S. aureus from various foods as well as saving time and space.

        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.

        This study attempted to understand the perception and the degree of trust that consumers had in the national agricultural food accreditation system, to inquire into and examine the consumers' perception of traditional food quality certification performed for the protection of excellent traditional food, and to propose the right direction for the policies on the traditional food quality certification system and the plans to improve consumers' perception of the system. According to the results of this survey performed in married women, based on the 'the recognition of accreditation system' and 'the recognition of certification marks' of 'the seventh national agricultural food accreditation system' presently being used by the Ministry for Food, Agriculture, Forestry and Fisheries, the household food purchasers showed high recognition for eco-friendly agricultural product accreditation, processed food KS certification, and organically processed food certification in that order. Meanwhile, it was shown that they indicated low recognition for the traditional food-related accreditation systems such as 'traditional food quality certification' and 'food grand master'. It was found that reliability of the certification mark provided by the agricultural food accreditation system gained 3.54 points (on a 5-point scale), and 68.1% of the study subjects referred to the certification marks while purchasing agricultural foods. And most of them answered to the question of 'why they referred to the certification marks' saying that it was done 'to choose safe food'. The most frequent answer to question of 'the means to recognize the traditional food quality certification system' was 'broadcasting, advertising'. 57.3% of the subjects had a previous experience of buying a product certified by the traditional food quality certification system, and 93.2% of all the subjects had the intention to buy a product certified by the traditional food quality certification system later. And most of them answered that 'strengthening government policies' would be the most ideal way to inform the public of the traditional food quality certification system. According to the results of this study, while 'relying on the traditional food quality certification system in general' was relatively high among the consumers, 'intention to buy quality certified products by visiting a distantly located store' was low; thus, from this analysis, it can be seen that there is a need for diversification of places selling these quality certified products and to establish a distribution network for these products.

For their own birthday, 32% said yes to preparing food at home while 45% said no difference and 22.3% said eating out. For children's birthday 65% said preparing at home, 16.3% said no difference and 14.9% said eating out. 3. Comparing the conception on traditional food, Korean women answered 'complicated' (77%) most while 'simple' (5%) least, which indicates their demands for simplified recipes. In case of Japanese women, 'complicated' (44%) was most while 'scientific' (6%) was least which indicates their demands for scientific way of recipes. There were differences shown by age (p〈0.001) and the older the more said 'simple' or 'logical' (p〈0.01). 4. As the reason for the complicity of traditional food recipes, Koreans said 'too many hand skill' (60%) most while 'too many spices' (8%) least. For Japanese, 'various kind of the recipe' (55%) was most while 'too many hand skill' (7%) was least. There were significant differences shown by academic background (p〈0.01) and income(p〈0.01), and the lower the academic background, the more said 'too many spices' as the reason for the complicity in making traditional food. Generally, the lesser the income, the more tendency to say 'various kinds of the recipe'. 5. In case of Koreans, 'the recipe is difficult' (56%) was high while 'uninterested' (9%) was low in answer which showed differences by academic background (p〈0.05), and in case of Japanese, 'no time to cook' (44%) was high while 'uninterested' (7%) was low. 6. The following is the reasons for choosing traditional food as a snack for children. In case of Koreans, they answered as 'traditional food' (34%), 'made from nutrious and quality materials' (27%), 'for education' (22%) and 'suites their taste' (17%) revealing 'traditional food' is highest. In case of Japanese, it was revealed in the order of 'made from nutrious and quality materials' (36.3%), 'traditional food' (25.2%), 'suites their taste' (22.6%), 'for education' (12.8%) and 7. Comparing the most important thing for the popularization of traditional food in the world, Koreans answered 'taste and nutrition' (45%) most while 'shape and color' (6%) least. In case of Japanese, 'taste and nutrition' (75%) was answered most while 'hygienic packaging' (4%) was least. Both considered 'taste and nutrition' as most important thing for the popularization of traditional food in the world. 8. In case of Koreans, they answered they learn how to make traditional food 'from mother' (47%), 'media' (18%), 'school' (15%), 'from mother-in-law' (14%), 'private cooking school' (4%) and 'close acquaintances' (2%). In case of Japanese, they said mostly learn 'from mother', but it was also shown that the lower the academic background the lesser the tendency of learning 'from mother' but 'from school' (p〈0.001). 9.

        The purpose of this study is to establish the one serving size of Korean Indigeneous Food. Serving size is necessary to make Nutrition Labeling which is required to export Korean food product especially to the United States of America. The basic data of 100 food items were collected through searching traditional and recent cookbooks. 4 industrial foodservices as noncommercial foodservice and 30 traditional ethnic restaurants and 12 gourmet restaurants in hotels as commercial foodservlce were explored to collect the data of actual serving size of each items. Moreover, experimental cooking and sensory evaluation by trained panels were conducted to assess quantity preference of selected food items. All data were rearranged through food type, that is, main dish, side dish, dessert and health food. One serving sizes showed wide variety according to the different menus that include selected food items. Therefore, means and ranges of serving size by four research methods were presented item by item. There were wide differences in intakes of main dishes, for example, noodles were around 50~100g, cereals were 20 g, which means the one serving size can be differenciated by the food usage. In intakes of side dishes, average of side dishes were 20~30g, but Kimches, the first traditional Korean food, were 30~50g, and the other condiments, pepper paste and soy paste were 5~10g. About desserts, liquid types were around 200 g, the other sugars were 10~20g, the kind of teas were almost 2~3g. The health foods-many kinds of that were Ginseng-were averaged 20 g; but dried mushrooms were around 2 g.
