Description

용암해수 고농도 미네랄 농축수{HIGH CONCENTRATION OF MAGMA SEAWATER MINERAL CONCENTRATED WATER}Lava seawater, high-concentration mineral condensed water {HIGH CONCENTRATION OF MAGMA SEAWATER MINERAL CONCENTRATED WATER}

본 발명은 30000uS/cm 이상의 전기전도도에서도 미네랄이 석출되지 않는 용암해수 고농도 미네랄 농축수에 관한 것이다. The present invention relates to a high concentration mineral enriched lava seawater in which minerals are not precipitated even with an electrical conductivity of 30000uS/cm or more.

용암해수는 바닷물이 화산 암반층에 의해 자연 여과되어 육지의 지하로 스며든 물로서 오염물질 및 유해세균을 함유하지 않으면서 칼슘(Ca), 아연(Zn) 등 다양한 미네랄성분을 포함하고 있으며, 담수화 과정을 통한 천연 미네랄 원료원으로 유용하게 사용되고 있다. Lava seawater is water naturally filtered by the volcanic bedrock and soaked into the basement of the land. It does not contain pollutants and harmful bacteria, and contains various minerals such as calcium (Ca) and zinc (Zn). It is usefully used as a raw material source of natural minerals.

다만, 사람이 용암해수의 미네랄을 충분히 섭취하기 위해서는 상기 용암해수를 농축시킬 필요가 있다. 그러나, 상기 용암해수를 농축시키는 과정에서 상기 미네랄이 용해 상태로 존재하지 않고 석출되는 현상이 발생한다. 따라서, 일정 농도 이상의 미네랄 농축수를 만들기 어려웠다. 결과적으로, 많은 양의 용암해수를 마시지 않는 한 사람이 충분한 미네랄을 섭취하기 어려웠다. However, in order for a person to sufficiently consume the minerals of lava seawater, it is necessary to concentrate the lava seawater. However, in the process of concentrating the lava seawater, the mineral does not exist in a dissolved state and is precipitated. Therefore, it was difficult to make concentrated mineral water above a certain concentration. As a result, it was difficult for a person to consume enough minerals unless they drink a large amount of lava seawater.

본 발명은 30000uS/cm 이상의 전기전도도에서도 미네랄이 석출되지 않고 용해 상태를 유지하는 용암해수 고농도 미네랄 농축수를 제공하는 것이다.The present invention is to provide a high-concentration mineral concentrated water of lava seawater that maintains a dissolved state without depositing minerals even with an electrical conductivity of 30000uS/cm or more.

상기한 바와 같은 목적을 달성하기 위하여, 본 발명의 일 실시예에 따른 용암해수 미네랄 농축수는 용암해수 탈염수에 구연산 무수물을 첨가함에 의해 제조되되, 상기 구연산 무수물은 상기 용암해수 탈염수 1톤 기준으로 0.13㎏ 내지 0.65㎏의 범위 내에서 첨가된다. In order to achieve the above object, the lava seawater mineral enriched water according to an embodiment of the present invention is prepared by adding citric acid anhydride to the lava seawater demineralized water, and the citric acid anhydride is 0.13 based on 1 ton of the lava seawater demineralized water. It is added within the range of kg to 0.65 kg.

본 발명에 따른 용암해수 고농도 미네랄 농축수는 용암해수 탈염수에 구연산 무수물을 첨가한 후 농축시키므로, 30000uS/cm 이상의 전기전도도에서도 미네랄이 석출되지 않고 용해 상태를 유지할 수 있다. 결과적으로, 더 높은 농도의 용암해수 미네랄 농축수의 제조가 가능하다. Since the lava seawater high-concentration mineral enriched water according to the present invention is concentrated after adding citric anhydride to the lava seawater demineralized water, minerals are not precipitated and the dissolved state can be maintained even at an electrical conductivity of 30000 uS/cm or more. As a result, it is possible to prepare a higher concentration of lava seawater mineral concentrated water.

본 명세서에서 사용되는 단수의 표현은 문맥상 명백하게 다르게 뜻하지 않는 한, 복수의 표현을 포함한다. 본 명세서에서, "구성된다" 또는 "포함한다" 등의 용어는 명세서상에 기재된 여러 구성 요소들, 또는 여러 단계들을 반드시 모두 포함하는 것으로 해석되지 않아야 하며, 그 중 일부 구성 요소들 또는 일부 단계들은 포함되지 않을 수도 있고, 또는 추가적인 구성 요소 또는 단계들을 더 포함할 수 있는 것으로 해석되어야 한다. Singular expressions used in the present specification include plural expressions unless the context clearly indicates otherwise. In the present specification, terms such as “consisting of” or “comprising” should not be construed as necessarily including all of the various elements or various steps described in the specification, and some of the elements or some steps It may not be included, or it should be interpreted that it may further include additional components or steps.

본 발명은 30000uS/cm 이상의 전기전도도에도 미네랄이 석출되지 않고 용해된 상태를 유지하는 고농도 미네랄 농축수 및 이를 제조하는 방법에 관한 것이다. The present invention relates to a high-concentration mineral concentrated water that maintains a dissolved state without precipitation of minerals even with an electrical conductivity of 30000 uS/cm or more, and a method of manufacturing the same.

용암해수 탈염수를 가열하여 농축수를 생성하면 농축수의 전기전도도가 높아지게 되며, 전기전도도가 30000uS/cm 이상 높아지면 미네랄이 용해된 상태로 존재하지 않고 석출되는 현상이 발생한다. When the concentrated water is generated by heating the demineralized lava water, the electrical conductivity of the concentrated water increases, and when the electrical conductivity is higher than 30000 uS/cm, the mineral does not exist in a dissolved state and precipitates.

따라서, 본 발명은 미네랄 농축수를 만들때 전기전도도가 30000uS/cm 이상 높아지더라도 미네랄을 용해된 상태로 유지할 수 있도록 용암해수 탈염수에 구연산(citric acid) 무수물을 첨가한다. 이 경우, 농축수를 만드는 과정에서 전기전도도가 30000uS/cm 이상 높아지더라도 상기 농축수가 미네랄을 계속적으로 포함하고 있게 된다. 결과적으로, 본 발명은 더 높은 농도의 미네랄 농축수를 만들 수 있다. Accordingly, in the present invention, citric acid anhydride is added to the demineralized water of lava seawater so that the mineral can be maintained in a dissolved state even if the electrical conductivity is increased by 30000 uS/cm or more when making mineral concentrated water. In this case, the concentrated water continues to contain minerals even if the electrical conductivity increases by 30000 uS/cm or more in the process of making the concentrated water. As a result, the present invention can make a higher concentration of mineral concentrated water.

전기전도도가 30000uS/cm 이상 높아지더라도 미네랄이 석출되지 않는 이유는 구연산과 미네랄이 매우 용해도가 높은 킬레이드 구조를 형성함으로써 용액 속 미네랄 이온의 정전기적 힘이 안정화되면서 미네랄 농도가 높아져도 서로 응집하지 않기 때문이다. The reason that minerals do not precipitate even if the electrical conductivity is higher than 30000uS/cm is that citric acid and minerals form a highly soluble chelaid structure, thereby stabilizing the electrostatic force of mineral ions in the solution and not coagulating with each other even when the mineral concentration increases. Because.

일 실시예에 따르면, 용암해수 탈염수 1톤 기준으로 상기 구연산 무수물은 0.13㎏ 내지 0.65㎏의 범위 내에서 첨가될 수 있다. According to an embodiment, the citric acid anhydride may be added within the range of 0.13 kg to 0.65 kg based on 1 ton of lava seawater demineralized water.

상기 구연산 무수물이 0.65㎏를 초과하면, 구연산과 미네랄이 구연산-미네랄 킬레이드를 형성하는게 아니라 점점 용해도가 낮은 구연산염을 형성하기 때문에 미네랄이 석출되는 현상이 발생한다. When the citric acid anhydride exceeds 0.65 kg, citric acid and minerals do not form citric acid-mineral chelates, but gradually form citrates with low solubility, so that minerals are precipitated.

이하, 본 발명의 고농도 미네랄 농축수의 실험예 및 제조 과정을 살펴보겠다. Hereinafter, an experimental example and a manufacturing process of the high-concentration mineral concentrated water of the present invention will be described.

구연산 무수물을 첨가하지 않고 용암해수 탈염수를 농축시킬 경우에는, 비교예1에서 보여지는 바와 같이 약 30000uS/cm의 전기전도도에서부터 탈염수에 용해되어 있던 미네랄이 석출되는 현상이 발생한다. In the case of concentrating lava seawater demineralized water without adding citric acid anhydride, a phenomenon in which minerals dissolved in demineralized water are precipitated occurs from an electrical conductivity of about 30000 uS/cm as shown in Comparative Example 1.

반면에, 구연산 무수물을 첨가한 실시예들에서는 30000uS/cm 이상의 전기전도도에서도 미네랄이 석출되지 않음을 확인할 수 있다. 이것은 구연산과 미네랄이 킬레이드 구조를 형성하였기 때문이다. On the other hand, in the examples to which citric acid anhydride was added, it can be seen that minerals were not precipitated even at an electrical conductivity of 30000 uS/cm or more. This is because citric acid and minerals formed a chelated structure.

다만, 구연산 무수물이 0.65㎏를 초과하면, 비교예2에서 보여지는 바와 같이 소정 전기전도도 이상(예를 들어 약 63000uS/cm의 전기전도도 이상)에서는 미네랄이 다시 석출된다. 이는 미네랄과 구연산이 용해도가 낮은 구연산염을 형성하기 때문이다. However, when citric acid anhydride exceeds 0.65 kg, minerals are precipitated again at a predetermined electrical conductivity or higher (for example, an electrical conductivity of about 63000 uS/cm or higher) as shown in Comparative Example 2. This is because minerals and citric acid form citrates with low solubility.
