Makgeolli is a traditional rice wine favored by the general public in Korea. This study investigated the fermentation and sensory characteristics of using wild yeast strains for brewing makgeolli. A non-Saccharomyces cerevisiae strain was isolated from nuruk and termed Y197-13. It showed 98% similarity to Pichia anomala and had an optimal growth temperature of $25^{\circ}C$. Makgeolli was manufactured using koji, jinju nuruk, and improved nuruk as fermentation agents. Y197-13 makgeolli brewed with koji had alcohol and solids contents of 11.1% and 13.9%, respectively. Sweet sensory characteristics were attributed to residual sugars in makgeolli with 6% alcohol. The makgeolli had a fresh sour taste and carbonated taste. Volatile component analysis showed the isoamyl alcohol, phenylethyl alcohol, isoamyl acetate, and fatty acid, including ethyl oleate and ethyl linoleate, relative peak area was higher in Y197-13 makgeolli than in makgeolli with Saccharomyces cerevisiae. These results suggest the wild yeast, Y197-13, as a candidate for brewing makgeolli.

Korean traditional Nuruk has been developed with various materials and shapes according to geographical environments and climates of their origins. Nuruk is also known as kokja in Korea, reflecting the understanding that microorganisms such as wild fungi, yeasts, and lactobacillus bacteria are naturally inoculated and reproduced. The objective of this study is to identify the characteristics of traditional Nuruk through recreating traditional production methods detailed in ancient Korean documents. In the present study, a total of 58 different kinds of Korean traditional Nuruk were prepared, including 46 kinds of recreated products. Each Nuruk sample was evaluated for its enzymatic activities, including glucoamylase, protease, and glucanase. Their suitability for alcoholic beverage production were compared to each other. To isolate valuable microorganisms from Nuruk samples, alcoholic beverages produced using each sample were subjected to sensory evaluation to determine their taste. In addition, metabolite changes in traditional alcoholic beverages fermented with different kinds of Nuruk were analyzed through mass-based metabolomics approach. This study presents, for the first time, the traditional production methods written in ancient Korean documents using workable production methods supported by modern technologies. In addition, this study analyzed the characteristics of reproduced Nuruk. It could be utilized as a basis for studying traditional Korean traditional alcoholic beverages and their valuable microorganisms.

The autoclave method and the traditional cooking method are compared for nutrients, mineral, color difference, viscosity, reducing sugar and amino nitrogen content of brown stock. For protein and amino nitrogen contents, the autoclave cooking method is better than the traditional cooking method. Also, reducing sugar content is increased by the autoclave cooking method. Since the color of brown sauce is related with reducing sugar content, the autoclave cooking method is more effective than the traditional cooking method for the color of brown sauce. Since the autoclave method can reduce the cooking time without the loss of quality in brown stock, the traditional method can be substituted by this new method.

About 760 papers and patents of the traditional fermented food in Korea were collected which were published during 1917-1988, and then the papers were classified, outlined and reviewed. Study of traditional fermented food was about 10% of total study on Korean Foods, and that of alcoholic beverage was 50%, soy sauce and related product was 30% and kimchi was less than 20% of total study of traditional fermented foods. Though considerable amount of studies were accomplished before the World War II, but a few study was accomplished during the Korean war. The research activity is, hitherto, increasing gradually, but the systematic studies were rarely done. The studies to be investigated were processing quality of raw materials, classification, standardization, sensory quality of the product and so on.

With the goal of searching for the ways to help market traditional beverages as take-out products, this study conducted a survey over men and women over 20 years of age in Seoul and Gyeonggi Province. Their perceptions of importance in choosing traditional beverages and conventional drinks were examined for difference. As a result, taste, reliability, health, flavor, and price were important at general beverage, while taste, health, flavor, reliability, price, and color were in choosing traditional beverages. The participants mentioned recovery from fatigue as the most favorable added feature of traditional beverages, which was followed by beneficial for adult diseases and facilitating digestion. Their preferences toward using them to satisfying a sense of hunger was relatively low. The participants preferred price range was $3,000{\sim}3,500$ won, their favorite ingredients were functional ones, and their favorite shop design was a traditional style. It seems that the marketability of traditional beverages as take-out products is high. The promotion and development efforts should involve marketing to women, differentiation strategies from other drinks, a graceful image, reliable drinks, and additional functions such as recovery from fatigue and can benefit adult diseases.

To investigate how the beverage consumption of middle school students are different in some respects; favorite kinds, drinking time and so on. 579 middle school students in Jeonju were participated in this study. This study shows the frequency of drinking beverage and the correlation between the frequency and the various factors to have effects on the frequency. The students usually drink water 8.55 times, milk or yogurt 3.01 times, sport beverage 2.13 times, soft drink 1.93 times, and fruit and vegetable juice 1.85 times for one week. The boy students prefer more soft or sport drink to the girl students. However the drinking of other beverages such as water, milk, juice, traditional ones don't have any meaning-ful differences between the boys and the girls. The students drink water mostly when they have meals. And the second consuming beverage is milk at table. It explains the students who drink more milk than water with bread. There is a big difference according to their excercise frequency. The students who excercise regularly or excercise over 3 hours drink more soft or sport drink and milk or yogurt than the students who exercise less than 1 hour. The beverages are firstly needed during the exercise because they sweat. And the second beverage time is when they have snacks and when they take a break. It should be suggested that nutrition education targeted to middle school students and their parents should encourage limited consumption of soft drinks. Therefore, policies that limit students' access to soft drinks at schools should be promoted.

진피를 시간별로 열수추출한 결과 pH는 가열시간이 증가할수록 감소하는 경향을 나타냈으며 산도는 증가하였으며 점도도 가열시간이 증가함에 따라 증가하였다. 굴절률은 180분간 추출한 것이 가장 높았고 추출시간이 증가할수록 높아졌으며 진피 열수추출물의 고형분 함량도 추출시간이 증가함에 따라 증가하였다. 전자공여능은 80.93∼83.27%로 나타났는데 가열시간 증가에 따라 증가하는 경향을 보였지만 유의적인 차이를 보이지는 않았다. 진피 열수추출물의 혈전용해 활성을 측정한 결과 추출시간 90분에서 감지할 정도의 약한 혈전용해능을 보였으며 추출시간 경과에 따라 혈전용해능은 점차로 증가하고 있음을 알 수 있었다. 진피 추출물을 이용하여 제조한 음료의 pH는 3.2∼3.6의 분포를 보였고, 설탕, 올리고당, 꿀의 세가지 감미료에 대해 큰 차이를 보이지 않았으며, 추출시간 역시 큰 영향을 주지 못하였다. pH와는 달리 음료의 산도는 가열시간이 길어질수록 증가하였으며, 특히 150분 가열시 증가폭이 컸다. 관능검사 결과 올리고당을 첨가한 진피음료의 기호도가 가장 낮은 것으로 나타났다. 전반적으로 볼 때 진피음료의 이화학적 성질은 감미료의 종류보다는 추출시간에 의해 영향을 받았으며, 관능적 품질은 감미료에 따라 차이를 보였다. 이상의 결과로 진피를 180분간 열수추출한 것이 항산화작용과 관계있는 전자공여능과 혈관질환에 관여하는 혈전을 용해시키는 능력 또한 우수한 것으로 나타났으며, 가열처리에 의해 이들 기능성이 제거되지 않은 점은 영양공급과 더불어 노화억제, 혈액순환 촉진 등 건강을 도모할 수 있는 기능성 전통 음료의 개발에 진피의 이용 가능성을 높이는 결과라 할 수 있다. 또한 관능적 품질을 위한 감미료는 설탕이나 꿀이 좋으며, 올리고당의 건강기능성을 이용하기 위해서는 설탕이나 꿀 등과 혼합사용이 필요할 것으로 여겨진다.
