This study was designed to elucidate the effect of fermented blackberry drinks (BD) on alcohol metabolism and hangover in alcohol-treated rats. We showed that the administration of BD increased the activity of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) in alcohol-treated rats. Moreover, the administration of BD reduced the serum alcohol and acetaldehyde concentrations in alcohol-treated rats. Furthermore, the administration of BD attenuated the levels of serum aspartate aminotransferase and alanine aminotransferase in alcohol-treated rats. Taken together, these results suggest that BD plays an important role in alcohol metabolism and liver function by reducing blood alcohol and acetaldehyde through the activation of ADH and ALDH in alcohol-treated rats and could be used as a functional anti-hangover drinks.

The purpose of this research was to examine the preferences of five traditional Korean drinks and analyze the factors affecting the preferences of children aged 7-12 in Korea, Vietnam, and China. The samples used in a sensory test were omija-cha, yuza-cha, sujeonggwa, sikhye and misutgaru. The test was performed to examine the overall, appearance (color), odor, taste and mouth-feeling and a sweetness intensity using 5 point hedonic scale (1=dislike extremely, 5=like extremely) and, check-all-that-apply (CATA) method was performed to determine preference and non-preferences factors. The preference of all samples except sujeonggwa showed significant differences in all items of the preferences (p<0.001). Almost items of the preference was rated more than 4 points in Chinese and Korea children. The sweetness intensity showed also significant differences in all items of the preferences except sujeonggwa (p<0.001), and evaluated as not sweet-appropriate with the score between 2 and 3 points. Sweetness, color, mouth-feeling, familiar flavor and healthy feeling was selected for the factors affecting the preferences. In conclusion, the result of this study determine the preferences and the affecting factors for the traditional Korean drinks in children of Korea, Vietnam, and China.

The environment of the health food in the world has been changed very rapidly. The world market volume of functional drinks in 2012 will be estimated at $ 26.9 billion, and Asia-Pacific market is expected to be $ 13.6 billion. The domestic market volume of bottled water in 2008 was 440 billion won, and "Jeju Samdasu" sales was 89.1 billion won. But the brand of "Jeju Samdasu" has the limits. As a solution, the comprehensive advertising of the excellence quality of Jeju water is required. To increase the likelihood of success in development of functional and mixed drinks by the water is necessary to develop a global integrated brand. In developing the functional and mixed drinks by the water, we apply the functionality of the Jeju agricultural products actively, and connect Jeju Water industry with Jeju agricultural industry, which promote the overproduction control and the high value- added agricultural products.

The discovery of bioactive compounds in foods has changed the dietary lifestyle of many people. Cyperus esculentus (tigernut) is highly underutilized in Africa, yet tigernut extract is highly profitable in Europe. This study aims to add value to tigernut extract by revealing its health benefits and food value. In this study, tigernut tubers were germinated or roasted and the extracts were combined with Moringa oleifera extract (MOE) or Hibiscus sabdariffa extract (HSE) and spiced with ginger to produce functional drinks. The drinks were evaluated for physicochemical characteristics, sensory parameters, and antioxidant potentials. The total phenolic content of each beverage was measured by the Folin-Ciocalteu method, and the antioxidant activity of each beverage was determined by the 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid assays. The beverages from the germinated tigernut extracts had the highest titratable acidity and the lowest pH, while beverages containing the roasted tigernut extract had the highest $^{\circ}Brix$. Germination and roasting significantly enhanced the total phenolic content of the drinks. The beverage containing HSE and germinated tigernut extract had a total phenolic content of 45.67 mg/100 mL gallic acid equivalents, which was significantly higher than the total phenolic content of all other samples. The DPPH inhibition activity of the beverages prepared with germinated tigernut extracts was significantly higher than the DPPH inhibition activity of the beverages prepared with fresh tigernut extract. The taste and overall acceptability of drinks containing the roasted tigernut extract were preferred, while the color and appearance of drinks with the germinated samples were preferred. Roasting or germinating tigernuts before extraction and addition of MOE or HSE extracts is another way to add value and enhance the utilization of tigernuts.

The purpose of study was to assess the influence of acidic drinks on the erosion of tooth enamel and the effect of fluoridated saliva on the remineralization. Twenty five drinks were sampled. The erosive potential and remineralizing effect were measured by the tooth surface microhardness test. The pH of most drinks were below pH 5.5. Reduction rates of enamel surface hardness by the flavored carbonated drink were 16.90%, 25.11%, 35.10%, and 41.62% after 5, 10, 30, and 60 minutes of demineralization, and recovery rates by remineralizaing solution were 61.52%, 67.96%, 72.13% and 75.93% after 1, 24, 48, and 72 hours of remineralization, respectively. The results suggest that the most drinks in the markets have the potential to erode the teeth and that erosion occurs fast but remineralization proceeds slowly.

Carbonated drinks are a kind of drink that is popular in our daily lives and are sold mainly among young people. There are many brands of carbonated drinks currently on sale, and most of them emphasize the distinction of texture, and brand images and packages have further commercialized package design as a whole. It is necessary to increase the emotional experience of soda package design, which can increase the added value of the brand. Sensibility is the most common psychological experience in humans and is the subjective experience and feeling of things. By combining the emotional experience with the package design of carbonated drinks, it provides more emotional user experience while purchasing carbonated drinks, realizing diversification of product package designs and satisfying consumers' emotional needs. This paper first examines the package design of carbonated drinks, I hope it will be an implication if you increase the emotional experience of soda package design.

Recently, interest in the environment and well-being is increasing due to changes in people's level of consciousness. Accordingly, it is trying to reduce disposable products, and interest in "water diet" is increasing as a way to maintain a healthy body. Many people use portable tumblers to drink water or drinks, and in particular, recently, they have evolved into a smarter form that provides various functions to increase user convenience. Existing studies have limited drinks to "water," so there is a limit to monitoring various drinks. To solve this problem, this paper produced a smart tumbler that can judge drinks using IoT technology and monitor the intake of drinks. In addition, it became possible to measure the intake more accurately by judging the case of throwing away the beverage without drinking it. Based on the data of various IoT-based sensors, the user can identify the intake amount of each drink in a dedicated application and receive various conveniences.

Purpose: The purpose of this study was to provide basic data for the management of atopic dermatitis (AD) in adults by analyzing the relationship between AD and intake of soft drinks in adults. Methods: This study was conducted on 5,931 adults aged 19 to 64 who completed the food frequency questionnaire (FFQ) for participants in the Korea National Health and Nutrition Examination Survey VII-3 and VII-1. Subjects were divided into an AD-diagnosed group and a non-AD group according to the diagnosis of AD. In addition, the group diagnosed with AD was divided into a 'symptom-AD' group and a 'no symptom-AD' group. The amount, frequency of intake, and nutritional status of soft drinks were analyzed using the FFQ. Results: Compared with the nutrient intake per 1,000 kcal of energy consumption, fat intake was higher in the AD-diagnosed group than in the non-AD group, and carbohydrate, dietary fiber, calcium, phosphorus, iron, potassium, vitamin A, thiamin, and vitamin C were lower in AD-diagnosed group. The daily intake of soft drinks and the percentage of 'more than 0.5 servings per day' were also higher in the AD-diagnosed group than in the non-AD group. Also, the frequency of the intake of soft drinks was significantly higher in the AD-diagnosed group than in the non-AD group. The odds ratio of AD symptoms due to the intake of soft drinks increased 2.6 times when the intake was 'less than 0.5 serving per day'. Conclusion: AD in adults appears to be related to malnutrition and excessive consumption of soft drinks, and the current prevalence of AD symptoms may also be related to the intake of soft drinks. Based on these results, we suggest that one of the ways to manage AD in adults would be to limit their intake of soft drinks.
