  • Sesame(Sesamum indicum L.) is probably the most ancient oilseed crop known in the world. The seed of sesame is used in a variety of ways as food. The whole seed may be eaten raw, either roasted or parched, or fed to birds and stock. Sesame oil is used as a salad or cooking oil, in shortening, margarine and in the manufacture of soap. Minor uses are as a fixative in the perfume industry and formerly as a carrier for fatsoluble substances in pharmaceuticals such as penicillin. One of the minor constituents of sesame oil, sesamin, is used for its synergistic effect in pyrethrin insecticides, in addition of a small quantity of this substance markedly increases the effectiveness of fly sprays. The meal remaining after oil extraction can be used as and animal feed-stuff or as manure. In general sesame meal is considered to be equal to cottonseed or soybean meal as a protein supplement for livestock and poultry. It is especially high in certain amino-acids such as methionine, which is low in soybean meal, and thus can be combined with it or similar meal to form a more balanced ration. An attempt to summarize the literature review on quality improvement of sesame was made to discuss the accomplishments of the past and perspectives in the future. The reviews on quality improvement of sesame were mainly discussed in connection with the cultural practices and genetic informations in current status. The emphasis focussed on environmental variation of quality in cultural practices, such as harvest time, variety by location, climatic condition, fertilizer application, and growth regulator treatment. On the genetic variation of quality, it was discussed on variety background, mutation breeding, correlations, and inheritance of quality related characteristics. It also was discussed on relationship between quality and plant traits, storage condition or period, and seed coat color. Moreover, current research status were reviewed on some minor elements such as sesamin, oxalic acid, and trypsin inhibitor. As a results of the review, the lack of an effort to quality improvement in each utilization area was indicated as a problem area. More active efforts for the improvement of quality were also insufficient to incorporate the available genes for quality in breeding method or collection and analysis of breeding materials. Therefore, researches in the future would be recommended to emphasize on these problem areas.

  • The purpose of this paper on Hoe (raw beef) is to investigate various kinds of its recipes, with equal focus on seasonings and sauces as well as its main and sub ingredients. The recipes of Hoe can be broadly classified into four large groups such as Salkogi Hoe(Red meat Hoe), Hankazi Naechang-yook Hoe(made from internal organs), Jap Hoe(1)(miscellaneous Meat Hoe) and Jap Hoe(II)(rolled with a whole pinenut) while the cook books written before 1945 indicate that the number of recipes reaches up to 21. The recipe of Salkogi Hoe comprises following three steps. Cut raw beef into thin strips and season them if necessary, then sprinkling sufficient pinenut powder on the strips. Its main sauce is hot pepper paste with vinegar. The recipe of Hankazi Naechang-yook Hoe uses kidney, manyplies, liver and tripes as main ingredients. Kidney should be thinly sliced with mixture of salt, seasame salt, seasame oil, and pepper as its seasonings. Regarding Manyplies, liver and tripes, there exists two possible ways to season them after cutting into strips. You can season with sesame oil and pepper or only with salt. Main ingredients of Jap Hoe(I) consist of beef, pork, kidney, manyplies, liver and tripes, among which minimum two ingredients are selected. Ingredients selected are sprinkled with pinenut powder after cutting into thin strips. And Hot pepper paste with vinegar is used as main sauce. The recipe of Jap Hoe(II) is to cut manyplies into pieces of 2Cm by 5 Cm without removing their black part and roll each piece with a whole peanut in such a manner that the peanut sticks from rolled piece.

  • The effects of various NaCl levels (0, 0.3, and 0.6 M) and pH values (pH 5.0, 5.5, 6.0, and 6.5) on the emulsifying and gelling properties of pork myofibrillar protein (MP) were assessed. The emulsion stability index (ESI), emulsifying activity index (EAI), and creaming index were measured at a 1:20 ratio of MP to corn oil. The EAI and ESI of pork MP showed maximum values at pHs 6.0 and 6.5 and at 0.3 M NaCl, resulting in better emulsion properties. Additionally, the cooking yield (CY) and gel strength (GS) of emulsified MP gel were measured at an MP: corn oil ratio of 1: 2; GS increased with increasing levels of salt. At 0.6 M NaCl, GS decreased with decreasing pH from 5.5 to 6.5. GS and gelling properties were optimal at pH 5.5 in 0.6 M salt. The highest CY was observed at 0.6 M NaCl, regardless of the pH value. However, increasing pH increased CY at salt levels of 0 and 0.3 M. These results indicate that NaCl and pH profoundly affected the emulsified MP system. Future work will be conducted on the rheological properties of the pork emulsified system as affected by adding non-meat protein.

  • When oil is used for cooking in detached or apartment houses, large amounts of oil-mist, smoke, and particulate substances are generated and dispersed into the indoor-air environment. These pollutants diffuse into the surroundings and spread their odor while rising fast at a high temperature due to the heat energy from the gas range. Although the exhaust gas is discharged from the exhaust hood, which is installed on the top of a gas range to remove the diffuse pollutants, the exhaust conditions can vary greatly because they depend on the shape of the exhaust hood and the discharge rate. In this paper, the air that is required for the gas-exhaustion process is supplied by an air curtain that surrounds the kitchen hood, and the pollutant-capturing efficiency varies depending on the angle of the discharge grills; the pollutant-capturing efficiency was studied using a numerical-analysis method. The results indicate that the pollutant-capturing efficiency is not significantly changed by a change of the discharge-grill angle at a low air-discharge rate; however, at a high air-discharge rate, the efficiency value increases with an increase of the discharge-grill angle, whereby the best value occurs at 30 degrees and the efficiency decreases above this angle. Below 30 degrees, the effect of the discharge rate on the capturing efficiency is more than that of the discharge-grill angle.

  • In this paper, the differences between Korean and Japanese ways of seasonings are studied. The main results are summarized as follows: (1) Shouyu and Miso which are Japanese equivalents of soy sauce and bean paste of Korean foods are used in variety of different seasonings with some other ingredients while Korean counter parts are used only to add salty tastes. (2) Shouyu and Miso lose their flavors after considerable time of heating, while Korean soy sauce and bean pastes increase their tastes after heating. (3) Mirin adds sweety taste and glaze and Sake makes food soft or hard according to the moment of being added during cooking. (4) In Korean foods soy sauce, bean paste and red pepper paste are on the basis of tastes, Dashi is used in almost every Japanese food. (5) Seasoned vegetables of Korean food are prepared only with spices of green onion, garlic and sesame oil while seasoned fishes or vegetables are mixed with Shoyu or salt and vinegar in Japanese food. (6) In making Zorim, Korean traditional sauces are added from the beginning of heating. But in making Nimono, sugar, salt, vinegar, Shoyu and artificial taste are added in order during heating. (7) In grilling, main food for grilling in Korea is meat, which is prepared with a variety of spices such as soy sauce or/and red pepper pastes, garlic, green onion, sesame oil, sesame powder, pepper and sugar while mainly fishes are grilled with salt, occasionally with Shoyu or Miso in Japanese food. (8) Pan frying fishes are taken with soy sauce with vinegar in Korea but Tepura are eaten with Tentsuyu in Japan.

  • To promote health status, strategies and interventions to improve nutrition should be based on the proper diagnosis of the subject's eating patterns. The elderly usually have traditional food habits and preferences, and it is very difficult to change them. This study was designed to identify dietary behavior and food preference of the elderly, in order to provide baseline data for the Elderly Nutrition Intervention Program for the Public Health Center. A survey questionnaire was made for use by trained interviewers to query 151elderly people from 5 community elderly centers located in Suwon, Korea. The majority of them ate regularly and partook of all available side dishes. Their major dietary problems were frequent consumptions of salty foods, and eating too quickly. They consumed grains and vegetables regularly, but seldomly ate dairy products, fruits, meat and food prepared with oil. They also tended to eschew ready made processed food, high cholesterol food, and fast food. Also they did not dine out as much as younger people. Desirable eating habit score were not significantly influenced by socioeconomic variables and nutrition-related characteristics. These included nutrition knowledge, Nutritional Risk Index(NRI) and a score of health concerns. However, meal balance scores were significantly higher in the younger group(p<.05), the higher household income group(p<.05). According to stepwise multiple regression analysis, NRI was the most important determinant of a desirable eating habit score for the male elderly, whereas the score of health concerns was mo9st important for female elderly subjects. The greatest predictor of the meal f balance score was nutrition knowledge. The elderly liked sweet tasting food, grains, rice, stews and Korean style soups. They disliked sour food, dairy products, processed food, and bread. The results indicate that the Elderly Nutrition Education Program should focus on increasing consumption of dairy products, fruits and food with oil, prepared by traditional Korean cooking methods. It also suggests that the program planning should consider the socioeconomic status of the elderly, such as income and education level, as well as concern for health.

  • This study was carried out to investigate the effects of addition of pork fat, olive oil and soybean oil on the quality and sensory of ground pork meat. The samples consisted of the ground pork meat containing 20% pork fat (GP-P), 20% olive oil (GP-O), and 20% soybean oil (GP-S). The chemical composition, surface color, fatty acid composition, water hold-ing capacity, pH, VBN content and TBARS value were determined for the ground pork meat as the quality characteristics, and the sensory score were also evaluated. The moisture, crude protein, crude fat and crude ash content were not different among the GP-P, GP-O and GP-S. The $L^{*}$(lighaess), $a^{*}$(redness) and $b^{*}$(yellowness) of /GP-P were higher than those of the GP-O and GP-S (p<0.05). Palmitic acid was the most abundant among saturated fatty acids, and palmitic acid content of GP-P (24.384%)was higher than that of the GP-O (15.611%) and GP-5 (14.423%). In case of unsaturated fatty acids, oleic acid of GP-P (43.773%) and GP-O (65.040%) were the highest, linoleic. acid for GP-5 (40.762) was the highest. The water holding capacity of GP-P was higher than that of the GP-0 and GP-5, the pH of GP-S was higher than that of the GP-P and GP-O, and the VBN content and TBARS value of GP-P was higher than that of the GP-O and GP-5 (p<0.05). The raw color of GP-0 and GP-S were higher than that of the GP-P (p<0.05), however the raw aroma was not different among the samples. In case of roasted ground pork meat, the aroma was not different among the samples, the taste, texture and palatability or GP-S were the highest among the samples, and the juiciness of GP-O and GP-S were higher than that of the GP-P(p<0.05).
