The quality characteristics and antioxidative activity of garlic pickles prepared with persimmon vinegar with or without Maesil (Japanese apricot) juice were investigated. Heat treated garlic cloves ($110^{\circ}C$, 5 min and then rapidly cooling) were salted with NaCl and $CaCl_2$, and then soaked in pickling solution, and stored at $20^{\circ}C$. The pH of the garlic pickles initially ranged from 2.36~3.24, after which the pH slightly increased to 3.22~4.13 during storage, while the acidity was decreased to 1~1.97. Throughout the entire storage periods, the acidity of the garlic pickle containing persimmon vinegar and Maesil was the highest (1.97%). The hardness of the control sample (non heated garlic) decreased during storage, whereas the hardness of all the heat treated groups did not change after 21 days of storage. Moreover, the chewiness of the persimmon vinegar+Maesil group was the highest among the groups. The Hunter color L value of garlic pickles decreased during storage, while the b value (yellowness) increased for all groups except the two persimmon groups. The $IC_{50}$ of the DPPH radical scavanging activity of garlic pickles at 5 day of storage was 85.98~97.81 mg/mL. However, the antioxidative activity of garlic pickles gradually increased with longer storage times. The persimmon vinegar+Maesil group showed the highest antioxidative activity. Results from the sensory evaluation showed that scores of flavor, taste and over-all preference were higher for the persimmon vinegar+Maesil group than the other groups (p<0.05).

In the meat industry, correct breed information in food labeling is required to assure meat quality. Genetic markers provide corroborating evidence to identify breed. This paper describes the development of DNA markers to discriminate between Japanese Black and F1 (Japanese Black${\times}$Holstein) breeds. The amplified fragment length polymorphism method was employed to detect candidate markers absent in Japanese Black but present in Holstein. The 1,754 primer combinations yielded eleven markers that were converted into single nucleotide polymorphism markers for high-throughput genotyping. The allele frequencies in both breeds were investigated for discrimination ability using PCR-RFLP. The probability of identifying F1 was 0.9168 and probability of misjudgment was 0.0066 using four selected markers. The markers could be useful for discriminating between Japanese Black and F1 and would contribute to the prevention of falsified breed labeling of meat.

본 연구는 국내 시장에서 어획된 생 원료 장어(붕장어와 뱀장어)를 찜, 숯불구이, 가스구이로 조리 및 진공포장하여 냉동 후 재가열하여 바로 먹을 수 있는 Cook/Freeze system을 단체급식 및 외식산업에 적용하고자 사업체 급식소의 한국인 피급식자(100명 )와 한국의 S업 체를 방문한 일본인 소비자(105명)를 대상으로 다음과 같이 소비자 기호도 검사를 실시하였다. 이상의 연구결과로부터 한국인과 일본인 소비자는 모두 붕장어의 경우 가스구이를 가장 선호하였으며, 뱀장어의 경우 한국인은 붕장어와 마찬가지로 가스구이를 가장 좋아하였으나 일본인은 숯불구이를 가장 좋아하는 것으로 나타났다. 장어종류에 따라 한국인과 일본인이 좋아하는 조리방법이 약간 다른 경향을 보였으나 일본인은 한국인과 비교해 볼 때 찜도 다소 좋아하는 것으로 보였다. 그러나 국내에서 장어를 가공할 때는 찜의 조리법은 별로 선호하지 않는 경향을 보여 가스구이나 숯불구이로 가공하는 것이 바람직하다고 사료된다. 소스에 인삼향과 송이향을 첨가하여 조리된 장어음식의 기호도를 조사한 결과, 국내 소비자는 일본인 소비자보다 모든 기호도 항목에서 유의적으로 높게 나타났다. 특히 인삼 첨가군의 기호도는 일본인 소비자가 한국인 소비자에 비하여 상대적으로 낮게 평가되었음을 알 수 있었다. 이는 자극적이지 않고 담백한 일본의 음식에 대한 기호성과 관계가 있는 것으로 판단되며, 한국인과 일본인 소비자의 기호성에 적합한 장어음식의 소스개발이 필요하다고 사료된다.

While ruling Chosun, with a view to making Chosun the primary supplier of food, Japan made the peasantry of Chosun go to ruin by leaving land from them through land enterprises, and the projects of increasing rice production. At the same time, Japan formed the higher classes comprising pro-Japanese capitalists, landlords and intellectuals, and protected them in order to carry out her colonial policies. Naturally there came into being a great gulf between the minority of high society and the majority of the poor in Chosun. As there was a great difference in food life between the two, I'm going to examine the literature of those days to grasp exactly the condition of their food intake. As for the staple food, out of thirteen provinces in Chosun, 13% lived on only rice and 27% on other minor cereals with no rice. As for the subsidiary food, about thirty percents did not take any animal protein. The examination of intake of nutrition by classes shows that the higher and middle classes took the necessary amount of calorie and protein and that the component ratio of calorie was comparatively properly distributed. The lower classes are defined as those whose monthly income was less than 100 won and the peasantry in general. And again the peasantry are classified into three-high, middle and low-according to their farming conditions. The tenant farmers in Kyeongguido and the peasants of Darli community took enough amount of calorie and protein, but much smaller amount of animal protein. Fire-field farmers led not less miserable food intake than the extremely poor peasants. They seldom lived on rice. Potatoes, oats and millets were their staple food. Lastly, Engel's coefficient for the Tomack-min (the residents in mud huts) who were among the three extremely poor classes, was 73.3%, which was much higher than that of the lower classes in then Japan. Rationed rice and barley were their staple food but the rationed amount was not sufficient to satisfy needs of physical labor. In conclusion, during the period of Japanese ruling of Chosun, the minority of higher and middle classes in Chosun generally took sufficient amount of nutrient, while the status of food intake with poor peasants, fire-field farmers and Tomack-min was extremely miserable.

The school food service system has been an important national policy in Korea. To find out the reference data of the school food service system, we surveyed four primary schools, one middle school, and one food service center in Nara, Japan. The results are as follows; 1. The school food service was carried out in 99.4% of primary school children and in 82.5% of middle school students. 2. The central commissary school food service system was utilized at 49.0% of primary schools and 68.5% of middle schools. 3. The expense of the system is supported partially by the student's parents and partially by the government, of which the support rate was noticed by the law of school food service. 4. The dietary content of school food service was laid down by 'The rule of the operation basis of school food service'. The menu was chosen by the 7 kinds of stepwise meetings. 5. The teachers emphasized on the food etiquette, the appreciation to the food and the personal relationship during meal, as well as on the nutritional balance. 6. We found other problems in Japanese food service system, such as the sanitary problems, the problems of the new tableware, and whether the central kitchen had less advantage than the individual school kitchen. We can conclude that the school food service system is becoming the essential part in school education, and hope to design not only economical but also educational system in Korea, with the consideration of Japanese system.

In Japan, Wagyu cattle include four Japanese breeds; Black, Brown, Shorthorn, and Polled. Today, the renowned brand name Wagyu includes not only cattle produced in Japan, but also cattle produced in countries such as Australia and the United States. In recent years, the intramuscular fat percentage in beef (longissimus muscle) from Japanese Black cattle has increased to be greater than 30%. The Japanese Black breed is genetically predisposed to producing carcass lipids containing higher concentrations of monounsaturated fatty acids than other breeds. However, there are numerous problems with the management of this breed including high production costs, disposal of untreated excrement, the requirement for imported feed, and food security risks resulting from various viral diseases introduced by imported feed. The feeding system needs to shift to one that is more efficient, and improves management for farmers, food security for consumers, and the health environment for residents of Japan. Currently, we are developing a metabolic programming and an information and communications technology (ICT, or Interne of Things) management system for Wagyu beef production as future systems. If successful, we will produce safe, high-quality Wagyu beef using domestic pasture resources while solving the problems of how to utilize increasing areas of abandoned agricultural land and to make use of the plant-based feed resources in Japan's mountainous areas.

Changes in lipid content, lipid class and fatty acid compositions of the cultured oysters in shallow-water, Bukman bay (Tongyeong, Korea), using both Korean and Japanese spats were investigated. The content of non-polar lipid (NL) comprised approximately $60- 80\%$ of total lipid (TL) in the cultured oysters. There was a positive correlation between NL content and meat weight, y=0.287lx-15.309 (r=0.834l, p<0.001). The prominent fatty acids of the oysters were 16:0, 20:5n-3 (eicosapentaenoic acid, EPA), 22:6n-3 (docosahexaenoic acid, DHA), 18:0, l8:1n-7, l8:1n-9, l6:1n-7, 14:0 and l6:4n-3. During the growth of the oysters, l6:4n-3 showed the highest coefficient of variation, accounting for $41.8\%$ for the Korean oyster and $32.3\%$ for the Japanese one, respectively. Both oysters showed low level of n-3 fatty acids such as DHA and EPA and high level of n-6 fatty acid, 20:4n-6, in the spawning period (August). During growth of the oysters, both EPA and DHA were the richest fatty acids in the harvest period (December, 314 mg/100g sample) and in the pre-spawning period (July, 237-247 mg/100g sample), respectively. Consequently, the cultured oyster with Japanese spat contained approximately two times more n-3 fatty acids per oyster individual than those with Korean one in the harvest season.

As for the Japanese dietary style and dietary equipments, many are regarded, with the rice plant imported, as the influence of China and Korea, while traditional culture has recently changed in Japanese and Korean urban lives because of the increase of nuclear families and modernization of lives. Of 1,244 junior high school students of boys and girls in Tokyo and Seoul, we investigated the present situations of the employment of dining equipments October to November, 1987. The results obtained are as follows. More cases that each member of a family had his or her own dining equipment were found in Japan. The frequency of using chopsticks was high in both countries. Korean children, having no struggles, handled chopsticks better than Japanese children. As for the dishing-up of sidedishes, more than half of Japanese used their individual plates, while in Korean families they used whole dishes. As for the employment of dining equipments, Japanese people have established their own style because of the national character of delicacy and finicality. This kind of traditional habits were found much more in extended families than in nuclear families. In Korea, the traditional spirit and the broad-minded characteristics cherished in the continental circumstances were manifested in the employment of dining equipments and their strong national character will not easily accept the wave of modernization.

This study was conducted to track the appearance of Aguijjim and its popularity on the national level. Furthermore, changes in the monkfish recipe and how they impacted the consumption of monkfish were investigated. It is assumed that monkfish was consumed by Japanese in Korea during the Japanese colonial era. After liberation, people cooked the fish as soup. In the 1960s, Aguijjim was invented in Masan. There is great controversy regarding how the dish was born. It has been asserted that it was created by one specific person, that refugees with insufficient food developed, and that it is just an advancement of Bugeojjim. Aguijjim restaurants began to appear in Seoul in the 1970s, and in the 1990s streets full of Aguijjim restaurants formed. Moreover, popular music and literature referenced Aguijjim in the late 1990s. As Aguijjim has developed and the formation of Aguijjim street have combined, the consumption of monkfish has increased drastically, leading to its import. As cooking methods have transformed, the fish with the unpleasant look which was thrown out in the past, have dramatically gained public interest. 'Masan Aguijjim' became an independent brand that represents a local food that has also been nationalized in a short amount of time.
