본 연구는 조리기구와 친환경 식문화콘텐츠의 접목형 융합상품으로 최근 소비자의 니즈를 반영한 단순한 전시용도가 아닌 새로운 상품으로서의 가능성을 제시하였다. 또한, 상품화를 위하여 본 과제에서 제작할 디자인이 반영되도록 3D Rendering, 3D Mock-up 등을 활용해 별도의 제작공정을 들여 프로토타입 형태로 제작하고, 이후 생산자와 협의 등을 통해 다양한 상품으로 확장 고려 될 수 있을 것으로 판단된다. 국내는 물론 국외에도 적용할 수 있는 조리 기구를 개발, 디자인함으로써 각자가 자신의 취향에 맞게 식재료를 가열하거나 고기 등을 구워 먹을 수 있도록 한 제품으로 기존에 출시된 그릴 팬에서는 찾을 수 없는 보다 앞서가는 기능과 현대의 변화된 식문화에 잘 부합하며, 감성적이며 형태적으로 교류할 수 있는 디자인을 더하여 참신하고 혁신적인 주방제품 트렌드를 리드할 수 있도록 하였다.

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.

Objective: This study aimed to elucidate the effects of cooking conditions on the physicochemical and sensory characteristics of dry- and wet-aged beef strip loins. Methods: Dry- and wet-aged beef aged for 28 days were cooked using different cooking methods (grilling or oven roasting)×cooking temperatures (150℃ or 230℃), and their pH, 2-thiobarbituric acid reactive substances (TBARS), volatile compounds, and color were measured. Results: Cooking conditions did not affect pH; however, grilling resulted in lower TBARS but higher cooking doneness at the dry-aged beef surface compared to oven roasting (p<0.05). In descriptive sensory analysis, the roasted flavor of dry-aged beef was significantly stronger when grill-cooked compared to oven roasting. Dry-aged beef grill-cooked at 150℃ presented a higher intensity of cheesy flavor, and that grilled at 230℃ showed a greater intensity of roasted flavor compared to wet-aged beef at the same condition, respectively. Conclusion: Grilling may be effective for enhancing the unique flavor in dry-aged beef.

조리조건을 달리하여 가열조리된 육류에서 형성된 단백질의 열분해 산물의 발암성을 검색하고 이의 제어방법을 검토하여 보다 안전한 조리법을 확립하고자 육류 중 돼지고기를 가스그릴(GG)과 전기그릴(EG) 및 전자렌지(MW)를 이용하여 온도별로 조리 한 후 이의 80% 메탄올 추출물에 대해 변이원성을 Salmonella typhimurium reversion assay(in vitro), micronucleus test(in vivo)를 실행하여 검색하였다. 또한 가열조리 중 생성되는 변이원성을 제어하고자 항암 성분을 함유하고 있다고 알려진 채소즙과 녹차 추출물을 시료로 침지후 조리하여 이의 변이원성을 검토하였다. 가열 조리한 시료의 농도별(0.5, 2.5, 5.0, 10.0 mg/plate) 변이원성은 농도의존성을 나타내었고, 시료농도 5 mg/$m\ell$/plate에서 유의적으로 높은 변이원성을 나타냈다(p＜0.05). 또한 시료의 조리온도가 상승할수록 변이원성이 증가하여 조리온도 의존성을 알 수 있었고 S-9 mixture 첨가시 변이원성이 2-4배 정도 증가하여 간접 돌연변이원이 더 많이 포함되어 있음을 확인하였다. 육류의 종류별 변이원성은 돼지고기가 유의적으로 가장 높은 변이원성을 보였고 닭고기가 가장 낮은 변이원성을 나타냈다(p＜0.05). 돼지고기를 채소즙 및 녹차즙에 침지후 GG, EG로 조리하였을 때 생강＞양배추＞무즙의 순으로 생강즙에 침지한 시료에서 변이원성이 유의성 있게 낮게 나타났다(P＜0.05). 돌연변이원 생성 억제 효과가 높았던 시료를 이용하여 Micronucleus test를 한 결과 생강즙 처리군이 유의적으로 낮은 소핵 형성률을 나타내어 생강이 소핵 형성 억제 효과가 가장 큰 것을 알 수 있었다(p＜0.05). 실용적인 면에서는 생강즙은 물과 동량인 경우 냄새가 너무 강하여 맛에 영향을 줄 수 있으므로 양배추나 무즙을 이용한다면 고온 가열 조리시보다 안전성을 확보할 수 있을 것으로 사료된다.

The purpose of this study was to evaluate the preference trend of frequently served meals in the elementary school lunch program. Therefore, this evaluation was surveyed on frequently served meals in the elementary school lunch program in Inchon. Also, this study was surveyed on food preference using questionnaire including frequently served food items. Statistical analysis of data was completed using SAS program. The results of this survey was as follows: 1. Freqrenctly served foods were 56 food items including 5 boiled rice, 3 one course dishes, 10 soup & pot stewes, 10 fresh & boiled salads, 8 stirred fries, 7 stewes, 6 grill & fries, 3 kimchies and 4 desserts. 2. Students liked barley bab more than the other kinds of cooked rice. One course dishes were preferred most by the subjects. Among soup & pot stewes, fermented soybean paste stew showed lower preference than the other kind of stewes. Among fresh & boiled salads, fruits salad was the most favore, whereas, root of bellflower salad was the most hated. Among side-dishes by different preparation method, stir fries, stewes, grill & fries, kimchies, dessert were prefered most by the subjects. There were significant difference between male and female students for most given foods except soup & pot stewes. Female students showed higher preference for most given foods except fresh & boiled salads, kimchies, dessert than male students.

The objective of this study was to determine the effect of reheating methods on the color characteristics of precooked pork patties with various NaCl and phosphate levels. NaCl/phosphate levels for each formulation were as follows; N1 (1% NaCl), N1+P (1% NaCl+0.3% phosphate), N2 (2% NaCl), and N2+P (2% NaCl+0.3% phosphate). The reheating methods used were by electric grill and microwave oven. The surface color of the patties reheated by microwave showed more brown and less-intense red, and the phosphate-treated patties reheated by microwave were more reddish and less brownish. With increased amounts of added NaCl and phosphate, the internal color of patties was more reddish, and the phosphate-treated patties reheated by microwave had more brown than those reheated by electric grill. Among all of the treatments, there were no significant differences in surface color, internal color, and overall appearance. Thus, the color changes in reheated patties were influenced by reheating methods and phosphate.

The waste bunker usually consists of waste entrance zone and waste pit. In this paper, the distributions of air flow, $NH_3$ concentration and $H_2S$ concentration in a waste bunker were investigated to prevent an odor generated in a waste pit from dispersing to the waste entrance zone by numerical method. Four cases were considered such that 1) the waste incinerators is operated, 2) the waste incinerators is stopped, 3) the waste incinerator is operated and the direction of a supply diffuser is $45^{\circ}$ upward, 4) the waste incinerator is stopped and the direction of a supply diffuser is $45^{\circ}$ upward. In case of 1), the fresh air from the waste entrance zone is exhausted smoothly to the main exhaust grill of the waste pit. It means that an odor dispersion to the waste entrance zone will not occur. However in case of 2), the induction of fresh air is so small and the supply air with an odor in waste pit can flow to the waste entrance zone. Therefore, an odor will be dispersed to the waste entrance zone. This paper shows the solution that the supply diffuser with the direction of $45^{\circ}$ upward is chosen. As a result in case of 3) and 4), an odor dispersion to the waste entrance zone does not occurred and on odor is exhausted smoothly to the auxiliary exhaust grill.

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 ${\mu}m$.
