본 실험은 $\beta$-cyclodextrin을 사용하여 cholesterol을 제거한 균질우유로부터 cholesterol이 제거된 치즈 제조의 조건을 규명하고, 그 조건에 따라 제조된 Cheddar cheese의 특성 및 관능 검사를 함으로써 cholesterol이 제거된 Cheddar cheese의 개발 가능성을 조사하는데 그 목적을 두고 있다. 따라서 균질온도는 $70^{\circ}$로 정하고, 균질압력을 750, 1000, 13009si(52.5, 70, 91kg/$cm^2$)로, $\beta$-cyclodextrin 첨가량을 1과 2%로 처리하여 제조한 6가지의 Cheddar cheese와 균질을 하지 않고 $\beta$-cyclodextrin의 처리를 하지 알은 control 치즈간의 수율, cholesterol 제거율, 용해성, 팽창성, 지방축소, 조직검사, 관능검사 등의 실험을 실시하여 control 치즈와 가장 유사한 cholesterol이 제거된 Cheddar cheese 개발의 가능성을 시도하였고, 그 결과는 다음과 같다. 1. Cholesterol을 제거한 Cheddar cheese의 제조에서 최적조건은 균질압력 1000psi (70kg/$cm^2$), 균질온도 $70^{\circ}$, $\beta$-cyclodextrin 침가량 1.5%였으며, 이때 우유의 cholesterol의 제거율이 86.05%로 가장 높게 나타났다. 2. 유지방 함량 23.80%인 control 치즈의 cholesterol 함량은 81.4 Cheddar cheese에서는 cholesterol 함량이 20.15mg/100g으로 cholesterol 제거율이 75.27%로 가장 높게 나타났다. 3. 용해성은 균질압력 1300psi(91kg/$cm^2$)에 $\beta$-cyclodextrin 1과 2%로 처리한 치즈에서 2.25cm(control 3.34cm)로 가장 낮았으며, 균질압력이 증가할수록 용해성이 감소하여 치즈의 품질을 저하시켰다. 4. Hardness, gumminess, chewiness는 균질압력 1200psi(91kg/$cm^2$)에 $\beta$-cyclodextrin 1%로 처리한 치즈에서 각각 가장 낮은 2.03kg/c$m^2$, 2.18kg, 2.24kg/cm(control 5.46kg/$cm^2$, 5.24kg, 4.87kg/cm)를 나타내었으며, control과 cholesterol을 제거한 치즈들 사이에 유의적(p<0.05) 차이를 보이며 큰 감소를 나타내었다. 5. 이 실험결과, 균질압력 1300psi(91kg/$cm^2$)에 $\beta$-cyclodextrin 1.5% 첨가한 Cheddar cheese에서 cholesterol 축소율이 75.27%로 가장 높았으며, 균질 처리가 Cheddar cheese의 수율, oiling off, appearance score, flavor scope 등을 향상시켰고, 용해성과 팽창성이 hardness, gumminess, chewiness, texture score를 저하시키는 것으로 나타나 cholesterol이 상당부분 축소 제거된Cheddar cheese의 개발 가능성이 관찰되었다.

Controlling food materials, is getting more significant in hotel management nowadays as the selling of food beverage continue to rise. F&B managers have been required to have new management of the food materials by a fierce competition, an increase in cost, the shortened span of product life and customer's demand that is becoming more various and sophisticated since Korea was placed under the influence of IMF. I'm going to analyze the factors that cause waste and loss through a series of the process to purchase inspect, store food materials, make a product with that materials and sell the product in order to make more profits by making the circulation of the food materials easier and more efficiently. I studied how 3 chain hotels of A group purchase, store the food materials and control stock. I made up questionnaires about the circulation and control of food materials to 107 cooks in order to know what the cooks who are working at the hotel regard as a real problem and a practical solution. This research indicates that purchasing, producing and selling departments don't establish the mutual connection, a professional purchasing manager is strongly needed and there is difficulty in predicting the proper timing to supply. Also the research shows that A hotel group controls the food materials by analyzing the amount of consumption, stock, setting up the period of validity and uses slowly moving food materials in stock mainly by introducing the menu that aims at four seasons. As a result, the research suggests that we should introduce the concept of food producing factory, as it were, Central Kitchen that is based on the network among various kitchens to improve the flow of the food materials.

단백질 분해효소활성을 가진 능이버섯 키위 배를 첨가하여 각 처리군의 수분함량을 비교한 결과 대조군에 비하여 능이버섯, 키위, 배를 첨가군 모두 첨가량이 증가할수록 유의적으로 수분함량이 증가하였다. 연육 효과가 있는 소재들을 첨가한 닭고기의 shear force를 비교해 보면 대조군에 비하여 능이버섯, 키위는 감소의 폭이 크게 나타났지만 배를 첨가한 것은 감소의 폭이 낮게 나타내었다. 닭고기의 색은 밝기를 나타내는 L값은 능이버섯, 키위, 배 모두 첨가량이 증가할수록 감소하였으며, 적색도인 a값은 첨가량이 증가할수록 증가하였고 황색도를 나타내는 b값은 능이버섯과 배는 첨가량이 증가할수록 증가하였지만 키위 첨가군은 첨가량이 증가할수록 감소하였다. 닭고기의 맛은 능이버섯 0.10% 가장 높았으며 능이버섯, 키위, 배 첨가 군 모두에서 첨가량이 증가할수록 닭고기의 점수가 낮아짐을 알 수 있었다. 닭고기는 능이버섯 1.5%와 배 10%첨가가 같은 점수 대를 나타내었다. 키위의 첨가는 능이버섯과 배에 배하여 맛이 떨어지는 것으로 나타났다. 가열한 닭고기의 색은 대조군이 가장 선호되었는데 이는 닭고기가 흰살이기 때문인 것으로 사료되어 진다. 닭고기의 향은 대조군과 배 10%첨가가 같은 점수로 높게 나타내었으며, 다즙성은 능이버섯 1.5%가 가장 높은 값이 였고 대조군 군이 낮게 나타내었다. 이것은 이들 소재의 첨가량이 증가할수록 수분함량이 증가한 결과와도 일치하였는데, 닭고기의 연화도는 이들 소재의 첨가량이 증가할수록 부드러운 조직감을 나타내었다. 배를 첨가한 군은 대조군과 비슷한 연화도를 나타내었고, 키위와 능이버섯 첨가군은 첨가량이 증가할수록 연화도가 증가하여 기계적인 조직감이 결과와도 일치하였다. 기호도는 배 10%군이 가장 선호되었고 그 다음이 대조군이며 키위 첨가가 가장 낮게 나타났다.

Flow properties of doenjang samples at various total solid contents (30, 32, 34, 36, 38, 40%) were evaluated in this study. Flow properties of doenjang samples was determined by using Haake concentric cylinderical viscometer and Instron testing machine with capillary extrusion viscometer, and consistency index(K), and flow behavior index(n) was also determined from power models, and yield stress was derived form Casson models and vanes methods. Doenjang samples showed shear-thinning (pseudoplastic) fluid with small magnitude of flow behavior index(n) (n=0.30-0.55). Casson yield stress was from 2.11 to 64.02(Pa). Vane yield stress was more effective than casson yield stress in property of reactivation. Apparent viscosity was decreased with the increase in temperature and activation energy was in the range of 6.58 to 10.70 kJ/mole. From the capillary extrusion method, K and n was increased with the increase in solid content with good correlation with. The result revealed that capillary extrusion method is useful for measuring the flow properties of doenjang.

약용버섯의 균사체(Ganoderma lucidum 7094, Fomitella fraxinea 81003, Phellinus igniarius 26005)를 곡류와 같은 고체재료에 배양하고 발효된 곡류의 유리당 조성 변화를 관찰함으로써 기능성식품 개발의 가능성을 검토하였다. 담자균사체의 대량배양 조건 실험을 실시한 결과, 냉침에 의해 최대수화에 도달한 곡물을 배양용기에 담고, 액체배양 후 균질화한 담자균사체를 곡물에 접종함으로써 접종초기 짧은 시간에 균사가 완전히 활착되도록 할 수 있었다. 또한 균사 배양중기에 멸균 증류수를 첨가함으로써 균사의 활력을 유지시킬수 있었다. 담자균사체는 종류에 따라 유리당 총량 및 구성비에 있어서 큰 차이를 나타내었다. 또한 담자균사체가 배양된 곡물의 유리당 함량을 측정한 결과, 유리당 총량 및 대부분의 유리당 함량이 곡물 자체에서 보다 증가하였으며, 담자균과 곡물배지의 종류에 따라 당의 이용성에 큰 차이를 나타내었다.

The temporary tax deduction on investment cutting the corporate income tax within 10% of the amount of investment is aimed at stimulating the investment for economic activity. 25 business sectors are applied to this tax law and in tourism, the accommodation registered by tour promotion law and international convention plan business belong to it. I'd like to mention the problem of the temporary tax deduction on investment amount for hotels and suggest better solutions. This tax law is so temporary applied that we shouldn't get tax deduction after June 30, 2002. So, we can't get income tax deduction on the investment out of the available period. And further more this tax law has a rule not real investment but solely new project investment for hotels. There are numbers of difference between real investment and new project investment. The amount of investment is based on an object of acquisition taxation. And also there are numbers of difference between real investment and an object of acquisition taxation. For example, landscape construction is a great part of hotel construction but it's not an object of acquisition taxation. For running hotel business, we also need lots of equipments such as linens utensils for restaurant and decorations for hotel interior. But these are also excluded from this tax law. As you know, these equipments can be regarded as product equipments in manufacture industry. Therefore we should take the specificity of hotel investment into consideration and expand the role of the temporary income tax deduction on investment amount for hotels.

The purpose of this study was to investigate the stress levels and the dietary patterns of 390 male and female University students in Seoul and to analyze the correlation between the two. Informations of the subjects were obtained by questionnaire. As a result of this research study, male students had such bad dietary patterns as their stress increased(P<.05). Female students were more affected in dietary patterns by stress level and both male and female students exhibited a tendency to be in a higher state of intake as their stress level increased.
