  • Various merchandises have appeared in recent markets of mineral water, beverage, food and cosmetics etc. These are almost manufactured by adding raw seawater, desalinated water, brine or salt from Deep Ocean Water(DOW), and it intimated desalination and mineral extraction are key techniques for DOW business. This study aims to verify the functional performance of mineral-controlled water produced by the basic methods which were proposed by authors for industrial purposes. This water revealed the possibility of the radical scavenging effects and moisturizing capability.

  • The purposes of this study were to find out the heavy metal and antibiotic resistant coliform bacteria from mineral water and the resistant factors. For the experiment, mineral water samples were taken from A area and B area during the period from march to July, 1988. The results of the experiment were as follows 1. From mineral water, eleven resistant coliforms and one susceptible coliform were isolated. 2. All resistant isolates harbored diverse plasmids of ranged ca. 14-54kb. 3. Susceptible coliform harbored a only plasmid of ca. 2.8 kb. 4. All resistant isolates harbored common size of plasmid of ca. 14kb. 5. As a result of the transformation and agarose gel electrophoresis experiments, resistant factor was R-plasmid. In conclusion, It is suggested that heavy metal contamination of mineral water is the selective pressure for the plasmid encoding the tolerance. Heavy metal resistance, in some case, is present with antibiotic resistance. Therefore, heavy metal contamination of mineral water induces antibiotic resistant bacteria.

  • The influence of refeeding with either vitamin, mineral, fibre of water on protein synthesis and mRNA content in the liver and breast muscle of fasted chicks was investigated. At 15 d of age, chicks were fasted for 2 d and then refed either vitamin, mineral, fibre or water. The fractional synthesis rate (FSR) of protein was measured after 30 min of refeeding by using a large dose injection of L - 2, $6[^3H]$ phenylalanine. In the liver, FSR was reduced by fasting and tended to increase but not significantly by refeeding with vitamin or mineral. FSR was not affected by refeeding with fibre or water. There was no influence of fasting and refeeding on ribosomal capacity (the RNA : protein ratio) and ribosomal efficiency (total protein synthesised per total RNA). The absolute synthesis rate (ASR) of liver protein and hepatic mRNA content were reduced by fasting and unchanged by refeeding. In the muscle, FSR, ASR and mRNA content were significantly decreased by fasting and not recovered by refeeding with either vitamin, mineral, fibre or water. It concluded that vitamin, mineral, fibre and water have little capacity to stimulate liver and muscle protein synthesis reduced by fasting.

  • 56 samples were analyzed to understand water quality of the natural mineral water of Korea. The geology according to each sample location is grouped into Precambrian metamorphic rocks, Okcheon metamorphic rocks, Jurassic granite, Cretaceous granite, and Jeju volcanic rocks. Average EC and pH values of the water is 150 μS/cm and 7.3, respectively and water type of the water is mainly Ca-Na-HCO3. Fundamentally, there still is no problem for the water quality of the natural mineral water. Nevertheless, nitrate was detected and arsenic and fluoride contents are near the drinking water standards, it is highly necessary to manage the water quality by installment of casing and grouting or by development of another production well.

  • Electrolyzed reduced water was known as an alkaline solvent than piped water, natural water and mineral water etc. By means of reduction property, electrolyzed reduced water could dissolve a solute than other kinds of water without chemicals. In this study, serpentine dissolution in electrolyzed reduced water was investigated as a novel pre-treatment of serpentine which was a minerals for carbon dioxide sequestration. The elements (Ca, Si, Mg etc.) of serpentine were dissolved rapidly at early in the dissolvation then after some minutes the solubilities of serpentine elements showed stable state without abrupt changes. In spite of serpentine elements dissolution, chemical bondings and crystallographic structure of serpentine were not changed. It was explained that the dissolution mechanism of serpentine occurred from surface in electrolyzed reduced water and bulk structure sustained without collapse.

  • In recent years, the sales of bottled spring water (BSW) have been drastically increasing in Korea and other countries, which accompanied great interests in conservation and reclamation of natural mineral water (NMW). In this study, management and research activities on NMW in Europe, USA, and Codex Alimentarius were reviewed. In each region, NMW is regulated with its own quality standards that differ from ordinary drinking water, and management actions are strictly implemented to protect water resources and to secure quality of NMW. Many studies on NMW were carried out for monitoring inorganic constituents including major and trace elements in national levels for bottled NMW, groundwater, and tap water in other countries. In Korea, NMW became commercialized in 1995 when BSW was legally approved as a drinking water. To further promote utilization of various types of NMW in Korea, regulations and policies for NMW need to be revised in accordance with international NMW management trends. Further, studies of NMW that compile a comprehensive set of physical and chemical parameters of NMW are also needed to properly understand occurrences, hydrogeological and geochemical processes of NMW, as well as to evaluate its potential use as a natural resource.

  • 청송 달기약수(상탕,중탕,하탕)의 수질특성을 파악하기 위해 1999년 5월부터 2000년 2월까지 약 1년 동안 계절별로 총 28개 항목의 함유성분을 분석하여 다음과 같은 결론을 얻었다. 각 탕별 약수의 수질에 큰 차이가 있었다. 하탕약수는 Mg과 Na이 상대적으로 높았?만? 중탕약수는 Ca, K, Si, Fe, Mn, 전기전도도, 총염기도, DO, $Cl^-$, $SO_4^{2-}$등에서 상대적으로 높은 값을 보였다. 건강상 유해성분인 As, Cd, $Cr^{6+}$, Hg는 검출되지 않았으며, Pb는 기준이하로 나타났다. 먹는물 수질기준을 초과한 항목으로는 경도, Fe와 Mn이었다. 그러나 샘물의 경우에는 이 기준을 적용하지 아니한다고 규정하였다. 약수의 계절별 특징으로는 온도를 제외한 기타 항목에서는 뚜렷한 차이가 없었다. 음용수에서 섭취할 수 있는 미네랄 양을 알아보고자 미국 국립과학아카데미의 하루 요구허용량과 섭취 음용수의 양을 1.O L로 하고 購종善嗤?기준으로 계산한 결과, Ca 35.05%, Mg 36.43%, Na 5.88∼10.63%, K 0.19∼0.57%, Mn 21.86∼43.72%, Zn 0.65%, Cr,Cu, P 등은 0.01% 이하이고, Fe는 95.1%이었다. 따라서 달기약수는 철분이 풍부한 약수임을 알 수 있었다.달기약수는 K index가 111.7∼254.6,O index가 2.3∼4.5로서 Hashimoto가 주장한 K index 5.2,O index 2.O을 상회하므로 건강에 좋고 맛있는 물의 조건을 만족하고 있다.

  • 칼슘, 마그네슘과 같은 양이온은 피부 장벽을 보호하는 기능이 있다고 알려져 있다. 본 연구의 목적은 칼슘, 마그네슘, 망간, 불소로 이루어진 미네랄워터의 피부 장벽 보호 기능을 확인하기 위한 것이다. 피부가 자외선에 노출되게 되면 밀착연접(tight junction, TJ)이 파괴되며, 밀착연접으로 이루어진 피부 장벽도 손상 받게된다. 미네랄워터가 자외선에 의해 손상된 피부의 장벽기능을 보호할 수 있는지 평가하기 위해 인공피부 모델을 이용한 실험을 진행하였다. 인공피부에 자외선을 조사하고 미네랄워터를 처리하면 피부 장벽 손상을 막아준다. TJ permeability assay를 통하여 자외선 처리 시 손상된 밀착연접 장벽이 미네랄워터 처리에 의해 유지되는 것을 확인하였다. 각질형성세포를 이용한 실험에서 미네랄워터가 밀착연접 구조를 유지시켜 주고, 자외선에 의해 감소된 occludin 단백질의 생성량이 회복되는 것을 확인하였다. 따라서 본 연구를 통해 미네랄워터는 자외선에 의한 피부 장벽 파괴를 막아주는 효과가 있음을 확인할 수 있었다.
