Makgeolli, also known as Takju, is a non-filtered traditional Korean alcoholic beverage that contains various floating matter, including yeast cells, which contributes to its high physiological functionality. In the present study, we assessed the levels of ${\beta}$-glucan and glutathione in various yeast strains isolated from traditional Korean Nuruk and selected a ${\beta}$-glucan- and glutathione-rich yeast strain to add value to Makgeolli by enhancing its physiological functionality through increased levels of these compounds. Yeast ${\beta}$-glucan levels ranged from 6.26% to 32.69% (dry basis) and were strongly species-dependent. Dried Saccharomyces cerevisiae isolated from Nuruk contained $25.53{\mu}g/mg$ glutathione, $0.70{\mu}g/mg$ oxidized glutathione, and $11.69{\mu}g/g$ and $47.85{\mu}g/g$ spermidine and L-ornithine monohydrochloride, respectively. To produce functional Makgeolli, a ${\beta}$-glucan- and glutathione-rich yeast strain was selected in a screening analysis. Makgeolli fermented with the selected yeast strain contained higher ${\beta}$-glucan and glutathione levels than commercial Makgeolli. Using the selected yeast strain to produce Makgeolli with high ${\beta}$-glucan and glutathione content may enable the production of functional Makgeolli.

참외의 부가가치 향상을 위한 일환으로 가공제품인 참외음료를 제조하였으며, 참외음료는 액상과당 $11\%$, 참외식초 $3\%$, 참외농축액 $1\%$ 및 정제수 $84\%$를 첨가하여 제조하였다. 참외 식초/농축액을 함유한 음료에 대한 저장온도 및 저장시간에 따른 관능적 품질 변화 및 이화학적 품질 변화를 모니터링한 결과 관능적인 품질과 이화학적 품질 모두 저장시간보다는 저장온도에 더 많은 영향을 받는 것으로 나타났다. 관능적인 품질은 낮은 온도에서 더 좋은 경향을 나타내었으며, 이화학적 품질에 있어 저장온도가 증가할수록 이화학적 품질의 변화가 크게 나타났다. 참외 음료의 관능적인 특성 및 이화학적 특성을 보존하면서 저장하기 위해서는 저장온도를 $60^{\circ}C$이하로 설정하는 것이 필요함을 알 수 있었다.

This study attempts to identify the most accurate quantitative forecasting technique for measuring the future level of demand for food ＆ beverage in super deluxe hotel in Seoul, which will subsequently lead to determining the optimal level of purchasing food ＆ beverage. This study, in detail, examines the food purchasing system of H hotel, reviews three rigorous univariate time series models and identify the most accurate forecasting technique. The monthly data ranging from January 1990 to December 1997 (96 observations) were used for the empirical analysis and the 1998 data were left for the comparison with the ex post forecast results. In order to measure the accuracy, MAPE, MAD and RMSE were used as criteria. In this study, Box-Jenkins model was turned out to be the most accurate technique for forecasting hotel food ＆ beverage demand among selected models generating 3.8％ forecast error in average.

This study is about choice attribution of customers make in food and beverage events. The researcher provided practical plans to uplift food-related enterprises and activate management through surveys and positive analyses, targeting customers who use food services. First of all, all event plans must include customer demands, social changes, special qualities of the business, and market research. Second, low demand season must be customers will be induced to the events. Third, prediction for market variable and solutions must be thoroughly examined and plans should look into the future to maintain a long period of time. Fourth, sufficient communication between planners and employees should be made before the event starts, so that food and beverage businesses can gain trust and quality of event services.Fifth, immaterial service and visible goods/menus in business of food and beverage events must be closely matched. Sixth, menus introducing a variety of merchandise, quality of nutrition and health of the business should be developed. Also, events from countries(regions) should be hold to create a market of cultural exchange. Seventh, for hereafter event plans, feedbacks are needed concerning customers needs and demands through customer care, after the food and beverage events. Eight, faculty management for convenience, kindness, safety, and life preserver accommodations in parking areas must be made, as automobiles are necessaries for people in Mycar era. The ninth, off-line and on-line care through on-line business construction and production of homepage must be done, due to the fact that even the well-made events are bound to fail if they are not delivered to the customers.

To evaluate customer satisfaction of hotel food and beverage products, developing items for the measurement is necessary through studying the properties of food and beverage products. The properties consist of human service, physical and systematic service. Human service includes appearance and uniforms, courtesy and kindness, quickness and precision of the service, well-educatedness, moral sense and etc. Physical service includes the taste of food and beverage, diversity of food and beverage, outlets' cleanness and atmosphere, refinement of fixture, furnishing and table ware, the admission passage to the hotel and parking lot facilities, and etc. Systematic service includes passages of movement to outlet, arrangement of outlet, reservation management system, operation of events and package goods, temperature and ventilation system and etc. The price is also one of important variables to measure customer satisfaction index, so it is included to the investigating items. As shown some hotels have several satisfactory items but most items are unsatisfactory because expected service is better than perceived service. Therefore, the hotels which lack human service need the reinforcement of service education, the hotels which lack physical and systematic services need the improvement, the development and the renovation according to the unsatisfactory items. And the hotels whose price item is unsatisfactory need to consider the policy.

The development of healthy beverages are increasing by big concerns for well-being. The aim of this study is to develop cultivated wild ginseng-Kyungohkgo (CKOG) beverage using cultivated wild ginseng instead of natural wild ginseng for Kyungohkgo. To examine physiochemical properties of CKOG beverage, pH, degree Brix, acidity, Huntor color, particle size and sedimentation volume were measured. When compared with commercial KOG beverage, CKOG beverage was lower in pH, acidity, particle size and higher in sedimentation volume. In the sensory evaluation of CKOG beverage, the best recipe of healthy CKOG beverage was 20% CKOG, 5.7% honey, 0.2% citric acid and 74.1% of water. In stability testing, pH, degree Brix, acidity, Huntor color of CKOG beverage was not changed, microbes in CKOG beverage was not detected for 60 days. These results suggest that CKOG may have a possibility of development as healthy beverage.
