This study investigated the intake of alcoholic and non-alcoholic beverages in college students. Five hundred and eighty seven students age 19-30 (432 male and 155 female) responded to the beverage consumption survey. Of the students 19.9% were freshman, 42.2% sophomore, 23% junior, and 15% seniors. Results are summarized as follows : 1) Beer and soju were the most commonly consumed alcoholic beverages by the college students. The amount of beverage normally consumed was 3 cans of beer or 1 bottle of soju. 2) There was no age related change in amount of alcoholic beverage consumed, but preference for liquor rather than beer increased with age. 3) Foods most commonly consumed prior to drinking were cooked rice and milk. 4) Following the drinking of alcoholic beverages the most commonly consumed food or beverage was cold water for both males and females. The next most commonly foods were cooked rice, instant noodles, and cola for males ; and cooked rice, milk, and fruit for females. 5) Cola and pear juice were the preferred non-alcoholic beverages for college students. Also popular among students were date juice for males and orange juice for females. Milk and non-cola carbonated beverages were not commonly consumed. This study provides information for the identification of possible alcoholic beverage related public health risks among college students.

Despite the abundance of research on alcoholic-beverage consumption in the food and beverage marketing literature, research directly assessing and comparing consumers' psychological motives for drinking different types of alcoholic beverages is relatively limited. There is also a paucity of research comparing drink-type specific consumption motivations in an Asian market. Paying attention to some recent new changes in the alcoholic-beverages market of South Korea, this study investigated South Korean young adult female consumers' alcoholic-beverage type-specific drinking motives. A self-administered online survey of 340 young adult female drinkers about their alcohol-consumption patterns, alcoholic-drink preferences, involvement with alcohol, and four types of drinking motives (coping, social, conformity, and enhancement motives) revealed differences in: (1) the association between the consumer's alcohol involvement level, alcohol consumption frequency/amount, and preferences for alcoholic beverages across different types of alcoholic drinks; (2) the underlying psychological motives for drinking different types of alcoholic beverages; (3) the association between consumption contexts and alcoholic drink types; and (4) the consumption patterns and drinking motives across different consumer groups that are segmented in terms of their most preferred type of alcoholic beverages. These findings point to the importance of investigating drink-type-specific consumption motivations in alcoholic-beverage consumption research. Limitations and implications for future research are also discussed.

In this study, a total of 58 different kinds of nuruk (a traditional Korean fermentation starter) were prepared, including 46 kinds of restored nuruk from ancient documents. Each nuruk was evaluated by analysis of its saccharification power, and the enzyme activities of glucoamylase, ${\alpha}$-amylase, ${\beta}$-amylase, protease, and ${\beta}$-glucanase. The range of saccharification power (sp) of the restored nuruk ranged between 85 and 565 sp. The diastatic enzymes, ${\alpha}$-amylase, ${\beta}$-amylase, and glucoamylase, were significantly correlated to the saccharification power value; conversely, ${\beta}$-glucanase and protease did not have a correlative relationship with saccarification power. In addition, their brewing properties on chemical and organoleptic aspects of traditional alcoholic beverage production were compared. Each raw and supplementary material contained in nuruk showed its own unique characteristics on Korean alcoholic beverage brewing. For the first time, in this study, the traditional Korean nuruk types mentioned in ancient documents were restored using modernized production methods, and also characterized based on their brewing properties. Our results could be utilized as a basis for further study of traditional alcoholic beverages and their valuable microorganisms.

There are many yeast strains have been discovered for industrial usage in global scale. In the point of view for the alcoholic fermentation performance and producing alcoholic beverage products, recently many countries have known about the importance of microorganisms as a valuable resource. Discovered with well performed yeasts have potential industrial application in diverse ways such as foods, beverages, cosmetics, pharmaceutical functions, and so on. In Korea, the yeast research has not been sufficiently performed especially for distilled spirits industry. As a result, not so little manufacturers use exotic yeasts from overseas even included the expensive royalties. Besides of those, to produce distilled spirits, many manufacturers do not use specialized yeast for distilled spirits. Distiller's characterized yeasts such as whisky, brandy, vodka, Japanese shochu and awamori, are all well-known industrialized. For decades, the distillers, except us, have selected, developed, and practised yeasts in accordance with distilled spirits characters. This study is about selection and industrial application of yeasts for the Korean pot distilled spirits. Finally 7 yeast strains were selected among over 1,000 yeasts from the traditional Nuruks, through the essential related tests based on brewing and distilling science. The selected yeasts show the appropriate characteristics of distilled spirits. The result of this study could help our distilled spirits industry be activated and stand independent from the exotic microbes.

Herein, nuruks derived from non-glutinous and glutinous rice inoculated with Aspergillus oryzae N159-1 (having high alpha-amylase and beta-glucosidase activities) were used to produce Korean alcoholic beverages. The resultant beverages had enhanced fruity (ethyl caproate and isoamyl alcohol) and rose (2-phenethyl acetate and phenethyl alcohol) flavors and high taste scores.

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.

Alcoholic beverages can be viewed as repositories of historical information reflecting agricultural environment, economic and scientific level, religion, literature and art of their country. Korean Alcoholic beverages are based largely on rice, which have been developed in the following order: Takju, Cheongju and distilled spirits, Soju. They are closely related with the development of agriculture and historical levels of science and technology, and thus can be seen as symbolizing economic and political changes as well as rises and declines throughout the culture's history. The present review assessed the past and present flows of Korean alcoholic beverage culture, which has had a significant influence on the mental world of Korean people, based on literature concerning the history of food in Korea. Another focus of the study was a discussion on the future transmission and refining of Korean alcoholic beverage culture, which is undeniably informed by the Korean people's unique imagination and cultural sense.
