  • In this experiment, citrus juice was fermented by Gluconacetobacter hansenii TF-2, an isolate from tea fungus to develop a new type of acidic beverage. The juice broth is made by fermenting of $11{\sim}17%$ (v/v) juice and sweetened with sucrose (initial sucrose $10^{\circ}Brix$). The fermentation by G. hansenii TF-2 was initiated by adding 5% (w/v) of seed gel (pellicle, tea fungus) which was previously cultured in the same medium (fresh juice broth) and the fermentation was carried out in a dark incubator at $28{\sim}30^{\circ}C$ for about 15 days. During the fermentation a pellicle grew on the surface of the fermenting fluid and acids were produced. Fermented fluid (beverage) was centrifuged at 7,000 rpm for 15 min for further analyses. The highest amount of the other metabolites including organic acids were observed in 5 to 10 days. Major acids were acetic acid (fermented citrus beverage, CB). After 15 days of fermentation, organic acid content such as acetic acid in fermented beverage was measured to be $183.5{\sim}186.6\;ppm$. Free sugars content in CB were 56.8%, 35.1%, 40.7% and 63.2% of unfermented sucrose, glucose, fructose and sorbitol, respectively. When the growth rate of inhibitory effect of the fermented beverage was measured by using several species of food-related bacteria, the beverage fermented with CB exhibited the strongest inhibition against gram-negative (E. coli and Sal. Typhimurium). Its inhibition rate was between $71.9{\sim}94.0%$ at CB. Fermented beverage has shown effectiveness for antimicrobial activity against some species of food-related bacteria.

  • This study was designed to investigate the amount of free sugar according to each beverage category in coffee and beverage stores. The groups were categorized as 15 groups based on the kind of beverage material. The beverage groups contributing to total sugar per 100 mL were milk + syrup or powder, hot (12.9 g), ade (12.6 g), milk + syrup or powder + crushed ice (11.9 g), and espresso shot + milk + syrup + crushed ice (11.4 g). The beverage groups contributing to free sugar per 100 mL were ade (12.6 g), milk + syrup or powder + crushed ice (10.8 g), espresso shot + milk + syrup + crushed ice (10.3 g), and milk + syrup or powder, hot (9.7 g). The beverage groups contributing to total sugar (energy) per portion size were milk + syrup or powder + crushed ice 56.6 g (332.3 kcal), espresso shot + milk + syrup + crushed ice 49.3 g (333.4 kcal), milk + syrup or powder, hot 46.3 g (372.1 kcal), and milk + syrup or powder, ice 38.1 g (325.9 kcal). The beverage groups contributing to free sugar per portion size were milk + syrup or powder + crushed ice 51.2 g, espresso shot + milk + syrup + crushed ice 44.9 g, ade 37.1 g, milk + syrup or powder, hot 34.6 g, and milk + syrup or powder, ice 30.1 g. The percent of average free sugar per portion size of the WHO recommendation (free sugars <10% of total energy; <50 g/2,000 kcal) was milk + syrup or powder + crushed ice 102.4%, espresso shot + milk + syrup + crushed ice 89.8%, ade 74.1%, and milk + syrup or powder, hot 69.2%. The proportion of beverage in excess of WHO recommendation per portion size was 14.6% in espresso shot + milk + syrup + crushed ice, 22.7% in ade, and 10.9% in milk + syrup or powder, hot. Therefore, in coffee and beverage stores, menu development with reduced sugar content is needed, and nutrition information should be provided through sugar nutrition labeling.

  • 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.

  • The purpose of this study was to study the relationship between the prevalence of constipation and beverage intake. Research data were collected from first and second grade female students at Hyehwa High School in Seoul by means of questionnaires. A total of 190 questionnaires were analyzed using the SPSS/WIN program. The results are summarized as follows: The average body mass index (BMI) was 20.7. Of the students, 38.4% had a BMI of less than 20(underweight), and 15.8% had a BMI of over 23 (overweight). However, 84.7% of the students wanted to lose weight. To estimate the prevalence of constipation, five factors were used: frequency and regularity of defecation, time spent defecating, defecation difficulty, and feeling of residue after defecation. The percentage of the students who emptied their bowels every day was 22.1%. About 2/5 of the students (42.1%) had irregular defecation, and 15.2% spent more than 10 minutes in the rest room when defecating. The students who did not have difficulty defecating and those who did not have feelings of residue after defecating were only 24.7% and 28.9%, respectively. The amount of beverage intake per day was 1,062$m\ell$ 674$m\ell$ of water, 128$m\ell$ of milk, 88$m\ell$ of soft drinks, and 53$m\ell$ of fruit juice. The amount of beverage intake before breakfast, during breakfast, before lunch and during lunch was about 100 $m\ell$, each; before dinner, during dinner, and after dinner it was about 200$m\ell$, each. The amount of beverage intake during the weekend was 120$m\ell$ greater than on weekdays. Students who drank more beverages, especially water, before breakfast, showed a higher defecation frequency, more regular defecation, spent less time defecating, had less difficulty defecating, and had less feeling of residue after defecation, so that they have a better defecation pattern. Based on these results, increasing the amount of beverage consumption, especially of water, and drinking greater quantities of beverage before breakfast are ways to reduce constipation.

  • To produce an intestinal immunomodulatory beverage containing Centella asiatica extract (CAE), three types of CAE-added beverage prototypes were prepared, and their immunomodulatory activities and marker compounds were analyzed. As a result of the cytotoxicity assessment, all the beverages did not show significant toxicity compared to the control group. Next, the immunomodulatory activities of the beverage prototype were evaluated using the inflammatory model of IL-1β-induced intestinal epithelial cell line. All the samples significantly reduced the production of IL-6, IL-8, and MCP-1 in a CAE concentration-dependent manner. In addition, CAE-added beverages inhibited NO, IL-6, and IL-12 production in LPS-induced RAW 264.7 cells. When the major triterpenoids, as marker compounds for the production of CAE-added beverages, were analyzed by HPLC-DAD, only asiaticoside was detected beyond the limit of quantification, while madecassoside, madecassic acid, and asiatic acid were not detected. The amounts of asiaticoside in CAE-added beverage prototypes were confirmed in No. 1 (19.39 ㎍/mL), 2 (19.25 ㎍/mL), and 3 (19.98 ㎍/mL). In conclusion, the results of this study suggested that CAE-added beverage prototypes induced immunomodulatory effects in the intestinal inflammatory cell line models and asiaticoside could be used as a marker compound for CAE-added beverage production.

  • This study was conducted to investigate the effect of beverage (beverage HC and beverage PG) using herbs on antimicrobial activity, proliferation of hepatic cancer cell (Hep3B) lines and sarcoma 180 (S-180) and antiallergy, respectively. Beverage PG showed higher antimicrobial activity than beverage HC against Staphylococcus aureus and Pseudomonas aeruginosa. Beverage HC and PG showed the tumor suppressive effect in mice injected with S-180 cells. The growth-inhibitoy ratio against tumor cells were $66\%\;for\;10\%$ beverage HC, $61\%\;for\;10\%$ beverage PG. In an anti-cancer test using Hep3B cells, beverage PG showed higher anti-proliferating effect than beverage HC. Beverage PG showed growth-inhibitory effect of $69.2\%\;at\;100\%$ beverage PG. Beverage PG inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. In conclusion, these results suggest that beverage using herbs have an antimicrobial activity, anti-proliferating effect against Hep3B cell and S-180 tumor and will be beneficial in treatment of allergic reaction.

  • This study is on the alcohol beverage utensils represented on the Chinese tomb mural paintings of Song, Liao, Jin, and Yuan those countries had foreign exchange with Koryo Dynasty. These mural paintings are distributed in the areas such as Hebei, Henan, Inner mongolia, Shanxi, Shaanxi, Peijing. etc. The Alcohol beverage vessels were classified mainly into storage vessel, pouring vessel, drinking vessel and ladles according to the purpose. The storage vessels of Song, Liao and Jin were called Jiuping, Jingping, Jiuzun as well as Meiping. Pouring vessels are basically one set of Zhuzi, Wenwan and Jiuzhu, or Zhuhu and Zhuwan. On the mural paintings of Yuan Dynasty, Meiping as storage vessels disappear, and a variety of shapes of pouring vessels such as Mayu and Yuhuchunping appear. This trend indirectly indicates the new arrival of distilled liquor, which seems to have affected transition of the alcohol beverage utensils.
