This study was conducted to investigate the physicochemical characteristics of Eungi, which is used as a breakfast or health food. We manufactured lotus root starch and Eungi by a traditional method and discovered that the viscosity of Eungi with 4-5% starch content was similar to fermented milk. When the physicochemical properties and sensory acceptability of a Eungi beverage combined with different amounts (0.5, 1.0, 1.5, and 2.0%) of lotus root starch were investigated, consumer acceptability was highest with Eungi combined with 0.5% starch and 6% sugar. When the physicochemical properties and sensory acceptability of Eungi beverage combined with different extract bases were investigated, the acceptability of taste and texture was highest with purple sweet potato extract and the acceptability of color was highest with omija extracts.

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.

Recently, much attention has been paid to developing various kinds of fermented herbal extracts, a new type of traditional herbal medicine, in the field of Korean traditional medicine. The fermentation of medicinal herbs is intended to exert a favorable influence on digestability, bioavailavility and pharmacological activity of herbal extract in the gastrointestinal tract. It also produces a number of fermentation products that intensify the nutritional and pharmacological aspects of the medicinal herbs. In order to develop a functional beverage of alleviating the aftereffects of the previous drinks, the extracts (HP-1) of fermented herbal mixture, including Artemisia capillaris Thunb., Lonicera japonica Thunberg, and Hovenia dulcis Thunb., were prepared and the medicinal effect as a hangover cure was evaluated in ethanol-loaded rats. The enzyme activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase-2 (ALDH2) were analyzed by measuring the concentration of blood ethanol and acetaldehyde. The mRNA expression of ADH and ALDH2 was also investigated through RT-PCR analysis. In the HP-1-treated group, the concentration of blood ethanol was significantly reduced at one hour after loading of ethanol, as compared to that in the saline-treated group. The reduced ethanol was converted to acetaldehyde, which resulted in rapid increase in acetaldehyde concentration in an hour. Acetaldehyde was started to decrease at 5 hours after ethanol loading. It implies that HP-1 is highly effective to stimulate the activities of ADH and ALDH2. The HP-1 treatment also activated the mRNA expression of ADH and ALDH. This study suggests that fermented herbal extract, HP-1 can be used as a functional beverage of alleviating the alcohol-induced hangover symptoms by stimulating the activities and gene expression of hepatic alcohol metabolizing enzymes.

Northern Kyungbuk around Andong is a mountainous and more or less dry region geomorphogically. Since this area located in the valley was less invaded by foreign countries, the folk traditions have been maintained for a long time. Also as the center of Confucian culture, this region respects ceremonies and so, the simple and noble ceremonial-foods such as Ddok, Hankwas, and Buchiki have been firmly preserved in many distinguished families. And besides Andong-Soju, many traditional liquors produced in different methods can be found in this region. As Gogi-Sikhae(a fermented beverage utilizing rice and fish) is still preserved in eastern coastal area, Sosikhae(Sikhae without fish) is maintained in this region and furthermore the unique Andong Sikhae developed by modifying Sosikhae is being consumed currently. Since it is difficult to get fish here geographically, the soybean foods were developed for protein intake, for example, various fermented soybean pastes, Andong-Songuksu(a hand-made noodle using raw soybean flour), and Siragiguk(a vegetable soup).

동치미를 이용한 알카리성 이온음료 제조의 타당성 및 개선방안을 고찰하고자 염도 2.0%, 2.4%, 무와 소금물의 비율 1 : 1.5로 담구어 $0^{\circ}C,\;5^{\circ}C,\;10^{\circ}C$에서 각각 숙성시킨 동치미의 성분을 분석하여 최적으로 숙성된 동치미액을 취해 이를 역삼투공정에 의해 농축하여 성분을 비교 분석하였다. 당함량은 숙성이 진행되면서 증가하였다가 숙성적기 이후에는 감소하는데 이는 숙성이 진행되면서 동치미내의 미생물작용으로 당의 전환이 이루어지기 때문으로 사료되어진다. 무기물 함량변화는 소금성분이 무 조직내로 침투하여 조직내의 $K^{+},\;Mg^{2+},\;Ca^{2+}$와 치환되어 동치미액 중의 $Na^{+}$농도는 감소하고 $K^{+},\;Mg^{2+},\;Ca^{2+}$농도는 증가하는 경향이었으며 숙성온도가 높고 염도가 높은 동치미에서 보다 많이 검출되었다. 이들 동치미액 중 각 실험조건에서 최적의 품질을 나타내는 동치미를 5l 취해 역삼투시스템을 이용하여 농축한 결과 압력이 높을수록 고농도의 동치미액을 얻을 수 있었다. 한편 기존의 이온음료와 성분분석 비교 결과 당함량을 제외한 전해질 성분은 동치미 및 동치미 농축액이 기존의 이온음료보다 훨씬 많은 함량을 띠고 있어 향후 이온 음료로서의 개발 타당성이 매우 높은 것으로 사료되었다.

Ethyl carbamate (EC) classified as a probable human carcinogen (Group 2A) is naturally formed in alcoholic beverages and fermented foods during fermentation process and/or during storage. The objective of this study was to analyze EC in 34 food items including 14 alcoholic beverages and 20 fermented foods sold in Korea. Each food was collected from 18 supermarkets in 9 metropolitan cities in Korea, and then made into composite. According to food composition and alcohol content, samples were divided into four matrices such as apple juice, milk, Soju (liquor containing about 20% alcohol), and rice porridge. The maximum EC value of $151.06{\mu}g/kg$ was found in Maesilju (liquor made from Maesil and Soju). Whisky and Bokbunjaju (Korean black raspberry wine) contained $9.90{\mu}g/kg$ and $6.30{\mu}g/kg$, respectively. EC was not detected in other alcoholic beverages. Of 20 fermented foods, Japanese-style soy sauce had highest level of $15.59{\mu}g/kg$ and traditional one contained $4.18{\mu}g/kg$. Soybean paste had $1.18{\mu}g/kg$, however, EC was not found in other fermented foods.
