Recently, the concern about safety and functional substances of foods are increased therefore antioxidant substances and plants which had pharmacological effect have been studied actively. It has been known that the mulberry leaf is effective in curing many diseases. Nowaday, the pharmachological effects of mulberry leaves on diabetes mellitus and their usage for many aspects were confirmed. Mulberry leaves are known for effective in prevention of diabetes mellitus, because of specific amino acids and fibers. In this study, methanol, hexane, chlorform, ethyl acetate, and butanol extracts obtained from mulberry leaves were added to soybean oil and they were stored for 30 days at 60±2℃ and peroxide value(POV) and conjugated diene value(CDV) were measured periodically. Results of this study were obtained as follows; 1. The POV of soybean oil after the addition of each mulberry leaves powder(MLP) extracts generally enhanced as the storage time was prolonged, so the POV of all samples was reached higher than 100meq./kg.oil after 10 days storage without the addition of butanol, methanol, ethylacetate, hexane extracts at 0.1% level. Especially, the POV of soybean oils including butanol extract was 87.35meq/kg.oil after 10 days storage and antioxidant activity of butanol extract was shown to be superior to that of BHT. The pattern of the changes of the CDV of soybean oil after the addition of MLP extracts at 0.02%, 0.05% and 0.1%, respectively, were almost constant during 10 days of storage and then rapidly increased during the rest of experimental periods. During 10 days of storage in case of 0.1% adding level, the antioxidant activities of the butanol extract was superior to that of the each MLP extracts.
The purpose of this study was to develop the standardized recipe and to analyze the nutrients of stir-fried whip-arm octopus as one of the kind of traditional local foods in Busan. The standardized recipe was developed by using cookbooks, home recipes, and the recipes by commercial food restaurants. The nutrient was analyzed by using an AOAC method. Sensory evaluations were made on nine sensory attributes by a 12-member panel. As the results, the whip-arm octopus was recorded as a food source for health, rejuvenation in Jasanobo. Since early 1900, the stir-fried method has been used for cooking with the ship-arm octopus. The main ingredients were whip-arm octopus, onion, large green onion as the local stir-fried whip-arm octopus in Busan. The ingredients of soup were shrimp, little neck clam, and water. Seasoning sauce was mixed with red pepper powder, soy sauce, sesame oil, chopped garlic, chopped onion, and sugar. The seasoning sauce was fermented for three days. The results of sensory scores were salty seasoning 3.66/5.00, taste 3.75/5.00, thickness 3.84/5.00, and smell 4.09. Nutrient retention per 100g of the stir-fried whip-arm octopus was 67.54kcal, protein 6.43g, fat 1.66g, Ca 28.06mg, Fe 2.56mg, cholesterol 68mg, and taurin 51mg. Fatty acid consists of various unsaturated fatty acids such as linoleic acid(46.24%) and oleic acid(33.67%).
This study was intended to collect the baseline information on dietary behavior of adults to develop nutrition education program in the context of health promotion at community level. Nutrients intake of 135 housewives were assessed by 24 hour recall methods. Also food habits, nutrition knowledge and attitude were investigated by self-administered questionnaires. Our results indicated dietary intake of calcium and vitamin B2 were insufficient when they were compared to Korean recommended dietary allowances(RDA). Among five food groups, intakes of milk and dairy product was inadequate as compared to the recommended amount. When we compared the fatness indices to self-evaluated meal problems, overeating and speedy eating were significantly related to fatness indices. Fatness indices such as relative body weight(RBW) and body mass index(BMI) were significantly higher in the subjects who self-evaluated their unsound food behavior as overeating. However, there were no significant differences of food habit score and nutrition knowledge among groups classified by fatness or meal problem. Body fat ratio, frequencies of night snack and skipping meal significantly increased with age. Food habit score was positively related to health-concerned attitude and active attitude toward change. We concluded that nutrition education program for housewives should include detailed strategies to modify unsound food behaviors for healthy weight.
The purpose of this study was to investigate the effects of different moisture addition and sugar on the quality of Nokcha-julpyun, during 24hrs. As the result of the Hunter's color values, lightness, redness and yellowness were increased slightly or not after 24hrs and showed middle levels in 30%~40% moisture addition groups. It seemed that the addition of sugar to Nokcha-julpyun affected the redness and yellowness of 40% and 45% moisture addition groups more than the other groups. In texture profile, springiness of Nokcha-julpyun was not different significantly among all the groups during storage. Cohesiveness was getting higher by increase of moisture level and getting lower by storage. Sugar addition seemed to lower the rate of decrease of cohesiveness. Chewiness and hardness were getting lower by increase of moisture level and getting higher during storage. In this case sugar addition seemed to interfere the Nokcha-julpyun to be hard. Adhesiveness showed to be decreased during storage, but didn't show any correlations with water level. Sugar addition to Nokcha-julpyun seemed to increase springiness and adhesiveness slightly. 35% moisture and sugar addition group had the lowest values in springiness, hardness and cohesiveness. Both 40% groups and 45% moisture and sugar addition group had high values in springiness, cohesiveness and adhesiveness but had the lowest values in hardness and chewiness. In sensory evaluation, 30%~40% moisture addition groups showed good preferences in color, flavor, taste, tenderness and chewiness, and the 35% moisture and no sugar addition group showed the best overall acceptance among the groups. Above results indicated that moisture addition level with 30%~35% seems to give the best quality to Nokcha-julpyun added green tea powder with 6% level, and for the purpose to reduce the changes of texture profiles during storage, it is benefit to add sugar a little to Nokcha-julpyun.
Fat and sugar reduced yellow layer cake system was developed with varied replacement level of 30%, 60%, and 90% for AD(amylodextrin) and 10%, 30%, and 50% for PD(polydextrose). Physicochemical and sensory characteristics were investigated and optimum replacement level was also decided using response surface methodology. Sample groups of PD10AD30 had significantly the lowest specific gravity and viscosity, indicating the stable batter system with high air incorporation. Sample groups with PD10AD90 showed the highest volume index and were not significantly different from those of the PD10AD30. Sensory results indicated that PD30AD30 were significantly the most springy and moist, and the least hard of all sample groups. Sample groups with PD10AD90 had the least adhesiveness value. To establish the optimum substitution level using RSM, the restriction level was set up as moistness over five point, hardness under five points, and adhesiveness under four points. The optimum substitution level was 20% for PD and 88% for AD.

The objects of this study are to find out (1) real situation of the food supply in prison under Imperial Government of Japan more cleary (historical meaning) and (2) which might help in understanding wrong present food consumption patterns in Korea which causes environmental as well as health problems. It is generally known that the length of the Japanese occupation for Korea is 36 years. However, it is concluded in this study that it was longer (70 years ; from 1875 to 1945 from when Japanese Army attacked and occupied Yungjongdo and Kanghwado island to e time when they were defeated on World War II.) Korea was annexed by Japan in 1910 then the Imperial Government of Japan dismissed the Korea Army, controlled the Office of Justice and the management of prison by force. Since then about 50% of all land was fell into Japanese Government ownership and 80% of Korean farmers became as tenant. After this change, Korea farmers were forced to pay extremely high rent (up to 80% of its harvest). Forced immigration, low price procurement of grain by Japanese government up to more than 30%of their production, was practiced. Accordingly, the food situation of Korean farmers became miserable, which may caused more violations of Imperial Japanese Law. Malnutrition, epidemic diseases, mortality rate of infants soared and average life expectancy shortened to 20-30 years old. This was the period of World Economic Crises and Food Crises in Japan. It was said then that if one Japanese comes to Korea then 200 Koreans will starved to death. Meanwhile, Proconsul Bureau of Chosun requested to the Department of Medicine, the Imperial University of Kyungsung to survey food supply situation of Koreans in prison throughout Korea. Objectives of the survey then was not only to find out scientifically whether it is agreeable in maintaining prisoner's health and also find out the possibility to save food during food crisis. Survey was started from 1923 and ended in 1945, and it focussed on prisoners in the Seodaemoon Prison. This report is the outcome of the first survey. They concluded that the food supplied was nutritionally (had) no problem, in compare with those of workers in the factory, students in the dormitory in Japan and with those of prisoners in Taiwan, France and Germany. Amount of grain supplied were different according to their work lord and was divided into 9 different levels. Total grain was consisted of 50% millet, 30% soybean and 20% indica rice(variety). However, there were no difference in the amount of supply of side dishes between work groups. For the highest working group, 3280g of boiled grain per day was supplied to make stomach full but as a side dishes, salty fermented bean paste, fermented fish and salty soups, etc. was supplied. Deficiency of animal protein were observed, however, high intake of soybean may possibly caused animal protein deficiency problem. On the contrary, the intake of water soluble vitamins were insufficient but the level of calcium and iron intake seems to be sufficient, however, imbalance of intake of nutrition may caused low absorbtion rate which might caused malnutrition. High intake of dietary fiber and low intake of cholesterol may possibly prohibited them from so called modem disease but may caused the defect in disease resistancy againist epidemics and other traditional disease. Over intake of salt(20-30g per day) was observed. Surveyors who attended in this survey, mentioned that the amount of food intake may nutritionally be sufficient enough but the quality of food(and possibly, the taste of food) were like that of animal feed. For the officials who received this report might consider that considering the war situation and food crisis, the supply situation of food in the prison may considered to be good enough(because they are not starving). But as a Korean who studied this report, one feel extremely pity about those situation because (situation of) those period were very harsh under the Imperi..
우리나라의 고유한 향신료로 활용되고 있는 소엽의 휘발성 향기성분 분석에 적합한 solid phase microextraction(SPME) fiber를 선정하기 위하여 carboxen/polydimethylsiloxane(CAR/PDMS)과 polydimethylsiloxane(PDMS)의 2종류 fiber를 이용하여 향을 추출한 후 GC/MS로 분석하였다. CAR/PDMS fber에 소엽의 향을 흡착시켜 분석한 결과, 39종의 성분이 확인되었으며, PDMS fiber를 이용하였을 때는 20가지의 향기성분이 확인되었다. 특히 PDMS fiber를 사용하였을 때 CAR/PDMS fber를 이용하였을 때 보다 perillaldehyde (40.50%), limonene (27.32%), E,E-,α-famesene (10.22%) 및 β-caryophyllene (8.02%)의 소엽의 주요 향기성분이 선택적으로 많이 확인되었다. 따라서 방향성 식용식물인 소엽의 향기를 SPME법으로 추출할 때는 PDMS fiber가 적합하다고 판단된다.
