This study was conducted to investigate physico-chemical changes of pork prepared by Korean traditional 3 types seasoning such as soybean sauce(Tl); garlic sauce(T2); red pepper sauce(T3). The seasoned samples were aged at 0 ${\pm}$ $1^{\circ}C$ for 30 days. The results obtained were as follows; Salinity(%) and saccharinity(%) of sauce were significantly decreased(P<0.05) among the all treatments during aging periods, whereas fermented meats were significantly increased(P<0.05). pH of sauce and fermented meat were tended to increased as aging period. Water-Holding Capacity(WHC) and shear force of fermented meat increased(P<0.05) among the all treatments at 20 days of storage, and decreased after that period. In color, $L^* and b^* value of T3 were lower, while a^*$ value was higher than other treatments during aging period. Volatile Basic Nitrogen(YBN) value of all treatments were increased(P<0.05) after 20 days of storage. YBN value of T3 was significantly higher(P<0.05) compared with other treatments. Thiobarbituric Acid Reactive Substances(TBARS) was rapidly increased until 10 days of storage and somewhat decreased up to 20 days after 10 days in all treatments, it was re-increased after 20th days. T3 showed the highest TBARS among the all treatment groups. Total bacterial and Lactobacilli spp. were significantly increased(P<0.05) in all treatments at 10 days of storage and decreased after that period, however it tended to increased at 30 days of storage. In sensory evaluation, overall acceptability in all treatments were increased after 20 days of storage compared to initial storage and it score was similar thereafter.

This study was conducted to assess the microbiological quality of raw and cooked foods served in the elementary school food service. Raw and cooked food samples were collected from 11 selected elementary schools in both June to July and September to October of 2005. Petrifilm plates were used to determine (in duplicate) total aerobic colony counts (PAC), Enterobacteriaceae (PE), coliform counts (PCC), and E. coli counts (PEC). Heavy contamination of Enterobacteriaceae (from 0.08 to 7.40 log CFU/g) and total coliform (0.50 to 6.52 log CFU/g) were observed in raw materials and cooked foods. Escherichia coli (E. coli) were detected in the sample of currant tomato (3.70 log CFU/g), sesame leaf (3.59 log CFU/g), dropwort (0.20 log CFU/g), crown daisy (3.15 log CFU/g), parsley (3.00 log CFU/g), peeled green onion (1.74 log CFU/g), frozen pork (0.65 log CFU/g), frozen beef (0.20 or 1.50 log CFU/g), chicken (1.78 log CFU/g), and young radish leaf seasoned with soybean paste (1.24 log CFU/g). Multiplex PCR system was used to determine the food-borne pathogens: Salmonella spp., Bacillus cereus (B. cereus), E. coli O157:H7, Staphylococcus aureus, Listeria monocytogenes (L. monocytogenes), Vibrio parahaemolyticus, Campylobacter jejuni (C. jejuni), Shigella spp., B. cereus was detected in 19 samples of raw materials and 8 samples of cooked foods. With regard to quantitative analysis, B. cereus counts exceeded 5.46, 3.48 and 1.79 log CFU/g in sesame leaf, peeled green onion and seasoned mungbean jelly, respectively. E. coli O157:H7 was detected on 2 samples of frozen beefs, and its biochemical characteristics of one beef sample was confirmed with API 20E kit (93.7%). L. monocytogenes was detected in fried rice paper dumpling, but the presumptive colonies were not detected onto the conventional plate. C. jejuni was detected in peeled & washed onion.

As the school lunch program is expanding to middle and high schools in Korea, a survey has been conducted to provide informations of the types and menus which are most favored on 190 middle and high school students in Metropolitan area. The sources/menus of foods relating to their lunches were proportionally ranked as: school food services (54.2%): individual lunch-box from home(37.4%); take-out lunch box(3.7%): school cafeterias(1.6%): and commercial restaurant, undefined, and skip a meal(1.1%). For the present practices for lunch, 52.1 and 47.9% of the students responded satisfaction on its sources and menus, respectively. A meal valued less than 2,000 won was paid by 54.9% of the respondents. In the meantime, 33.7 and 55.4% of the students were unsatisfied with lunch box from home and school cafeteria of the present lunch practices, respectively. The reasons against their satisfactions were enumerated as their preferences for take-out lunch box(22.2%), school cafeteria(21.0%), outside restaurant(17.3%), individual lunch-box from home(16.1%), school cafeterias(8.6%), and undefined (14.8%). For the individual lunch-box from home, two major obstacles, i.e., it is neither warm to eat, nor diverse/properly-sized in side dishes, were reasons for dissatisfaction of the students. The school lunch programs were blamed for its poor taste and lacks of variety and volume of the side dish which is mostly composed of kimchi, seasoned vegetables, and bulgogi. The most popular side dishes were pork- or fish cutlets, hams, and sausages while food with carrots, garlics or red peppers, vegetables like pumpkins, lotus roots, and seasoned vegetables were mostly disliked. It was concluded that the school lunch programs for middle- and high school students could be settled down by preparing with well-nourished food items that suits students' taste best and be served at right temperature.

The characteristics and quality changes of sauces containing different concentrations (5, 10, and 15%) of fermented Oenothra biennis juice (FOBJ) were studied for its potential as a new meat seasoning suace. pH of the seasoning sauce was ranged from 5.23 to 5.37. Sugar content of seasoning sauces increased decreasing on increase of FOBJ concentration while the color (L, a, b) decreased. DPPH radical scavenging ability and TBARS values of the seasoning sauce was increased significantly by the addition of FOBJ (p<0.05). The total bacteria number of the seasoning sauces was approximately 3 log CFU/g while coliform bacteria were not detected in all tested sauces. The sauce containing 5% FOBJ showed the highest value in taste, color, overall acceptability among all tested sauces. The pH and titratable acidity of the meat seasoning sauces was not changed significantly during 25 days at $10^{\circ}C$. The total bacteria number of the seasoning sauces was steadly 3.62~3.83 log CFU/g for 25 days at $10^{\circ}C$. The number of coliform was not detected during storage periods. These results suggested the possibility of development of new meat seasoning sauce containing FOBI.

The purpose of this study was to investigate the adaptation and preference for South Korean food among North Korean refugees. A survey was conducted on 220 North Korean refugees regarding general questions, adaptations, and preference on consuming dishes in South Korea. The results of the survey showed that the average difficulty degree scored with the adaptation to South Korean food was 3.06 points out of 5.00 points. The adaptation to Korean food was investigated as 'average' and some North Korean refugees had some difficulties in South Korean food. Some respondents described South Korean food as having very strong flavor that tastes more sweetened, seasoned, and spicy than North Korean food. The extended residency in South Korea allowed North Korean refugees to become more familiar with sweetened flavors. Most of them enjoy an oily and spicy taste more than South Koreans. North Korean refugees like Ssal bap, Naengmyeon, Doenjang-guk, Galbi-jjim, Bulgogi(beef, pork), Chaesobokkeum, Oi-saengchae, Chaeso-jeon, Baechu-kimchi, Saengsun-twigim, Soondae, pears, fruit juice, and spring water. North Korean refugees over the age of 30 years enjoy classic foods such as Japgokbap, Gimbap, Jumeokbap, Hwedeopbap, and Chobap. On the other hand, North Korean refugees less than 30 years old enjoy new foods like ramen and spaghetti.
