  • In this study, PM emission factors for commercial meat cooking were developed by the experiment using the similar restaurant model. The commercial material types of meat cooking were beef, pork and duck. And meat cooking materials were classified with marinated and raw cooking methods. The marinated and raw cooking methods were flat griddle (LPG) and under fired charbroiling grill. As a results, $PM_{10}$ emission factors for underfired pork cooking was estimated as 7.39 g/kg-meat which was the highest value in this study. The emission factors of under fired charbroiling grill method were higher than that of flat griddle method regardless of meat cooking material types and marinated meat. The particle size distribution of meat cooking was 0.23~5 ${\mu}m$ and median diameter was 2~2.5 ${\mu}m$.

  • Purpose: We consider export of Korea for Muslim population of Cairo residents in Egypt. Product instant cup noodle and yuzu tea are mainly focused on Kano model and Timko's customer satisfaction factor (CS - Coefficient) analysis and conjoint analysis. Methods: Based on the evaluation and conjoint analysis, cluster analysis was additionally applied to further exploratory research as to what kind of population the target customer has. A total of 120 people, each 60 people each, were prosecuted for Muslim women, middle middle class who had over 3,000 Korean won annual income for that study, and in Cairo in August 18. Results: The Kano analysis result Instant cup noodles act as attractive elements for packaging state, cooking method, smell and convenience, and Yuzu tea acted as an attractive element of taste, eating method, raw materials, efficacy, packaging form. Customer satisfaction factor, instant cup noodles, capacity and noodle thickness was a factor of indifference in Kano analysis, but acted as an attractive factor, the way to eat citron tea was classified as a factor of indifference. Conclusion: In the case of instant cup noodles, we first set up the taste of chicken-based soup with high appreciation as a whole, a group that likes chicken-based soup taste and oil noodles for each market segment, a taste of beef based soup And popular group that likes raw noodles Appears that diversification is necessary, and it has been found that it is necessary to develop a product type by hierarchy and marketing with different size priority from group packaging container. In the case of Yuzu tea, it is indispensable to emphasize the efficacy, in particular, energy recovery preference appears high, appealing point matching the needs of energy recovery is necessary, release the citrus fruit as a product without buckwheat in Bisson Ho, the packaging container, The group that likes cups and sticks is different and we found that it is necessary to prepare all two types.

  • This study was carried on the preferences for food intake pattern of Korean industrial workers. The survey was conducted from Feb 17, to March 31, 1992 by questionnaires which was composed of 21 items. The subjects of this study were composed of 426 clerical workers, and 439 physical workers. The results were obtained as follows. 1. In the educational background, clerical workers was almost of highschool or collage graduates, and physical workers was almost of highschool graduates. Marginal food cost of per person for lunch a day was from 500 Won to 1,000 Won. They replied that amount of staple food and side dishes were appropriate, and the type of preferable foods was Korean style cooked rice. Also it was known that physical workers thought their nutritive condition more badly than that of clerical workers. So the physical workers considered their health very much when they had meal. It was represented that unbalanced diet, without diet and drinking alcohol effected badly to food intake and taste of food was the most important point in food intake. 2. Preferences for staple foods; Cooked rice was preferred the most by the subjects. Cooked rice with redbean was preferred by clerical workers and cooked rice with soybean was preferred by physical workers and cooked rice with soybean was preferred by physical workers. Also clerical and physical workers liked Kalkooksoo (hot noodle), Nangmyun (cold noodle), bread, vegetable bread and disliked Sphagetti, Ramyun (Instant noodle) in same rate. In the next, cooked rice covered with raw fish pieces (Sushi) was preferred by clerical workers and Mandu-kook was preferred by physical workers. Also they disliked Curriedrice and Hashrice in same pattern. 3. Preference for side-dishes; The Acceptances for side-dishes were high soybean paste soup (clerical workers:43.7%, physical workers:34.4%), Kim chi stew, fried potatoes, crab steaming (37.8%, 36.9%), broiled fish (34.6%, 33.9%), fried green pepper, Ham, Chinese cabbage Kim chi, and pickled garlic by clerical and physical workers all together. But in clerical workers, Wooghugi beef-rib tang, Deodeok muchim, spinach namul, beef jangjeorim, fried shrimp were shown to have high preference in physical workers, beef-rib tang, wild onion and shepherd's purses muchim, soybean sprout, fish jeorim, fried sweet potatoes were high preference. 4. Preference of Snacks; The preferences for snacks were high in strawberry (clerical:36.3%, physical:34.3%), milk (49.9%, 44.4%), waxy rice Doek (30.7%, 30.2%), coffee (40.1%, 38.9%) by two groups in same order.

  • 비육후기 돼지 사료에 우지 5%를 첨가하여 급여한 돈육(대조구), 우지 3%와 들깨유 2%를 혼합하여 급여한 돈육(T1), 우지 3%와 오징어유 2%를 급여한 돈육(72), 우지 3%와 CLA 2%를 급여한 돈육(T1)을 1$\pm$1$^{\circ}C$에서 28일간 저장하면서 육짙특성을 조사한 결과는 다음과 같다. pH는 대조구가 나머지 세 급여구보다 유의적으로 높았으며, 저장기간 경과에 따른 차이는 보이지 않았다. 보수력은 처리간에는 일정한 차이를 보이지 않았으며, 저장기간이 경과할수록 대조구와 T3는 계속 증가하였으며, T1과 T2는 14일까지 증가 후 감소하였다. 단백질 용해성은 T3가 나머지 세 급여구보다 높았으며, 저장기간이 경과할수록 모든 급여구가 14일까지 증가 후 감소하였다. 육색 분석결과 a*값은 저장 28일 대조구가 나머지 세 급여구보다 높은 반면 b값은 낮게 나타났다. VBN은 T3가 가장 높고 T1이 가장 낮게 나타났으며, TBARS는 T2와 T3가 대조구와 T1보다 높게 나타났다. 신선육의 관능검사 결과 육색과 기호성은 대조구가 나머지 세 급여구보다 높게 나타났으며, 외관은 T1이 나머지 세급여구보다 높게 나타났다. 식물성유 대체 급여로 돈육의 품질특성에는 큰 차이를 나타내지 않았으나 불포화지방산의 증가로 인해 산화가 촉진되는 경향이 있으므로 항산화제를 함께 급여하는 것이 바람직하리라 사료된다.

  • Food labeling regulations require that the meat species in various meat products are accurately declared to the consumer. Substitution or adulteration of costly meat with a cheaper one is one of the most common problems in the meat industry. In this study, PCR-restriction fragment length polymorphism(RFLP) method of the mitochondrial cytochrome b(mt cyt b) gene has been applied for identification of the origin of six mammalian meat species(beef, port horse, goat, mutton and deer) and three poultry meat species(chicken, turkey and duck) as raw materials for meat products. PCR was used to amplify a variable region of mt cyt b gene. Meat species differentiation was determined by digestion of the amplified products with a 359 bp fragment using HaeIII and HinfI restriction enzymes, which generated species-specific RFLP patterns. This PCR-RFLP DNA marker of mt cyt b gene could be very useful for the accurate and reliable identification and discrimination of animal meat species in routine analysis.

  • An excavation of the Vesakoyakha II-IV and Nyamboyto I burial grounds was conducted during the 2014 field season, and soil samples from intact burials dating from the 19th and 20th centuries, respectively, were analyzed to determine interactions between parasites and host/vectors. Considering the discovery of Diphyllobothrium sp. and Taenia sp. eggs in soil samples from the pelvic region, diphyllobothriasis was the most frequent helminthic infection among the Taz Nenets. The Nyamboyto Nenets mainly consumed uncooked fish, while the Vesakoyakha Nenets had a bigger variety in food choices, including reindeer meat. Nenets children were given raw fish from early childhood. The paleoparasitological results corroborate rare ethnographic records about the consumption of uncooked reindeer cerebrum which led to beef tapeworm helminthiases. This is the first parasitological report of helminthic diseases among the Taz Nenets, and, as such, it provides insight into their subsistence activities and food patterns and broadens our understanding of their health condition.
