本発明は、酸化還元電位が−４００ｍＶ以下の水を、酸化還元電位を維持して殺菌する方法に関する。 The present invention relates to a method for sterilizing water having a redox potential of −400 mV or less while maintaining the redox potential.
本発明者は、原料水の酸化還元電位を−４００ｍＶ〜−６００ｍＶに低下し、その電位を維持する方法を開発し、特許願２００３−１９８７４７として特許出願した。 The inventor has developed a method for reducing the oxidation-reduction potential of raw material water to -400 mV to -600 mV and maintaining the potential, and filed a patent application as Patent Application 2003-198747.
本発明者がすでに出願した特許願２００３−１９８７４７に関わる発明は、酸化体と還元体の混合状態にある水の酸化還元電位を−４００ｍＶ〜−６００ｍＶに低下させ、その値を長期間維持することを発明が解決しようとする課題とし、その課題を解決する手段として、酸化還元電位が−４００ｍＶ〜−６００ｍＶ以下の水を、光、酸素、水素、水蒸気等に対し完全バリヤー機能がある容器に充填することから成るものであった。 The invention relating to the patent application 2003-198747 already filed by the present inventor reduces the redox potential of water in a mixed state of an oxidant and a reductant to -400 mV to -600 mV, and maintains the value for a long time. As a means to solve the problem, water having an oxidation-reduction potential of −400 mV to −600 mV or less is filled in a container having a complete barrier function against light, oxygen, hydrogen, water vapor, etc. It consisted of doing.
そして、特許願２００３−１９８７４７に関わる発明では、前記完全バリヤー機能がある容器として、アルミ箔を含むラミネートで製造された容積可変型容器とし、最外層の２軸延伸ポリエチレンテレフタレートフィルム、中間層のアルミ箔、最内層の特殊ポリエチレン、特殊ポリプロプレン、ナイロン−１２，ナイロン−１１，或いは特殊ポリエステルフィルムの３層構造の容器、いわゆるアルミパウチを例示した。 In the invention related to the patent application 2003-198747, the container having the complete barrier function is a variable volume type container manufactured by a laminate including aluminum foil, the outermost biaxially stretched polyethylene terephthalate film, and the intermediate layer aluminum. A container having a three-layer structure of foil, special polyethylene of the innermost layer, special polypropylene, nylon-12, nylon-11, or special polyester film, so-called aluminum pouch was exemplified.
ところで、特許願２００３−１９８７４７に関わる発明において、酸化還元電位が−４００ｍＶ〜−６００ｍＶ低下の水は、酸化体と還元体の混合状態にある原料水を、シリカ系石英斑岩に金属を担持させた還元触媒と接触させながら、水素をガス圧０．１〜０．９５ＭＰａで、１０秒〜１０分間吹き込んで原料水の酸化還元電位を−４００ｍＶ〜−６００ｍＶに低下させて製造される。 By the way, in the invention related to the patent application 2003-198747, the water having a reduction in oxidation-reduction potential of −400 mV to −600 mV is obtained by supporting the raw material water in a mixed state of the oxidant and the reductant with the silica-based quartz porphyry. While being brought into contact with the reduction catalyst, hydrogen is blown at a gas pressure of 0.1 to 0.95 MPa for 10 seconds to 10 minutes to reduce the oxidation-reduction potential of the raw material water to -400 mV to -600 mV.
当然、原料水は、製造プラントに供給する前に、予め、たとえば、ＵＦフィルター、或いはシャンベランフィルター（Ｃｈａｍｂｅｒｌａｎｄ ｆｉｌｔｅｒ）、ベルケフェルトフィルター（Ｂｅｒｋｅｆｅｌｄ ｆｉｌｔｅｒ）等で例示される細菌濾過器で殺菌するが、触媒から、或いは工程程管理の不完全さ等が原因で、細菌が混入する場合がある。従って、製造された酸化還元電位が−４００ｍＶ〜−６００ｍＶ低下の水を、そのまま飲用に供することができない場合がる。 Naturally, the raw material water is sterilized in advance with a bacterial filter exemplified by a UF filter, a Chamberland filter, a Berkefeld filter, or the like before being supplied to the production plant. Bacteria may be mixed from the catalyst or due to incomplete process control. Therefore, the produced redox potential of -400 mV to -600 mV may not be used for drinking as it is.
従って、発明が解決しようとする課題は、酸化還元電位が−４００ｍＶ〜−６００ｍＶ低下の水を、その酸化還元電位を維持して、そのまま飲用に供することができるように殺菌することである。 Therefore, the problem to be solved by the invention is to sterilize water whose oxidation-reduction potential is reduced by -400 mV to -600 mV so that the redox potential can be maintained and used as it is.
さらに、発明が解決しようとする課題は、酸化還元電位が−４００ｍＶ〜−６００ｍＶ低下の水を、酸化還元電位を−４００ｍＶ〜−６００ｍＶ低下に維持したまま、そのまま飲用に供することができるように殺菌することである。
発明が解決しようとする別の課題及び利点は以下逐次明らかにされる。Further, the problem to be solved by the present invention is to sterilize water whose oxidation-reduction potential is reduced by -400 mV to -600 mV and can be used for drinking as it is while maintaining the oxidation-reduction potential at -400 mV to -600 mV. It is to be.
Other problems and advantages to be solved by the invention will be clarified sequentially below.
酸化還元電位が−４００ｍＶ〜−６００ｍＶ低下の水は極めて不安定で、通常は、放置しておくと数時間〜１日で原料水の酸化還元電位に戻る。さらに、ポリエチレンテレフタレート（ＰＥＴ）、ポリエチレン、ナイロン、ポリプロピレン、ポリカーボネート等のプラスチック製瓶に充填した場合でも、２４〜４８時間後に電位が原料水の電位に戻るので、本来の商品価値はおろか、長期間の在庫が不可能であった。 Water with a reduction in oxidation-reduction potential of −400 mV to −600 mV is extremely unstable, and usually returns to the oxidation-reduction potential of raw material water within a few hours to a day if left untreated. Furthermore, even when filled in plastic bottles such as polyethylene terephthalate (PET), polyethylene, nylon, polypropylene, polycarbonate, etc., the potential returns to the potential of the raw water after 24 to 48 hours, so that the original commercial value is not only long-term Inventory was impossible.
本発明者は、特許願２００３−１９８７４７に関わる発明で、この酸化還元電位を３ヶ月維持することに成功したものである。 The inventor has succeeded in maintaining this oxidation-reduction potential for 3 months in the invention related to the patent application 2003-198747.
然しながら、酸化還元電位が−４００ｍＶ〜−６００ｍＶ以下の水の殺菌方法として、たとえば、塩化ベンジルセチルジメチルアンモニウム［Ｎ（Ｃ７Ｈ７）（Ｃ１６Ｈ３３）（ＣＨ３）２］Ｃｌ等食品衛生法で認可された殺菌剤を使用すると、水の酸化体、即ち酸素の活量、還元体、即ち水素の活量が変化し、酸化還元電位が変化し、場合によっては、原料水の酸化還元電位に戻るおそれがある。However, as a method for sterilizing water having an oxidation-reduction potential of −400 mV to −600 mV or less, for example, food sanitation such as benzylcetyldimethylammonium chloride [N (C 7 H 7 ) (C 16 H 33 ) (CH 3 ) 2 ] Cl When using a sanitizer approved by law, the oxidant of water, that is, the activity of oxygen, the reductant, that is, the activity of hydrogen, changes the redox potential, and in some cases, the redox of raw water May return to potential.
さらに、一層重要なことは、添加物を一切使用せずに、酸化還元電位が−４００ｍＶ〜−６００ｍＶ以下の水を殺菌することである。そのことにより、純粋に水だけを飲用し、或いはジュース等の分散媒として使用することができ、酸化還元電位が−４００ｍＶ〜−６００ｍＶ以下という超低電位の水を体内に摂取した際の生物電気化学的効果を発揮させることができるのである。 Furthermore, it is more important to sterilize water having an oxidation-reduction potential of −400 mV to −600 mV or less without using any additive. As a result, it is possible to drink pure water only or use it as a dispersion medium for juices, etc., and bioelectricity when ingesting ultra-low potential water with an oxidation-reduction potential of −400 mV to −600 mV or less into the body. The chemical effect can be exerted.
従って、酸化還元電位が−４００ｍＶ〜−６００ｍＶ以下の水を、酸化還元電位を上昇させずに殺菌する方法は、酸化還元電位が−４００ｍＶ〜−６００ｍＶ以下の水をアルミ箔を含むラミネートで製造された容積可変型容器に充填し、加熱殺菌することである。 Therefore, the method of sterilizing water having an oxidation-reduction potential of −400 mV to −600 mV or less without increasing the oxidation-reduction potential is produced by laminating water having an oxidation-reduction potential of −400 mV to −600 mV or less with an aluminum foil. In other words, the container is filled in a variable volume container and sterilized by heating.
本発明の特徴は、酸化還元電位が−４００ｍＶ〜−６００ｍＶ以下の水を、酸化還元電位を上昇させずに殺菌処理するに当たって、酸化還元電位が−４００ｍＶ〜−６００ｍＶ以下の水をアルミ箔を含むラミネートで製造された容積可変型容器に充填してから行うことである。実験の結果、アルミ箔を含むラミネートで製造された容積可変型容器以外の容器の場合は、酸化還元電位が上昇して所期の目的を達することができない。 A feature of the present invention is that when water having an oxidation-reduction potential of −400 mV to −600 mV or less is sterilized without increasing the oxidation-reduction potential, water having an oxidation-reduction potential of −400 mV to −600 mV or less includes an aluminum foil. This is performed after filling a variable volume container made of laminate. As a result of experiments, in the case of a container other than a variable volume container manufactured by a laminate containing aluminum foil, the oxidation-reduction potential increases and the intended purpose cannot be achieved.
本明細書で使用する用語「容積可変型容器」は、当業界に認知された用語ではないが、柔軟性材料で製造されていて容積を変更することができる容器と定義する。なお、「容積可変型容器」は、パウチと同義である。 As used herein, the term “variable volume container” is not an art-recognized term, but is defined as a container that is made of a flexible material and can change volume. The “variable volume container” is synonymous with a pouch.
本発明で使用するに適した容積可変型容器は、酸素、光、水素を完全に遮断し、内容品である水の変質を防ぐアルミ箔を含むラミネートである。たとえば、最外層に２軸延伸ポリエチレンテレフタレートフィルム（厚み１２μｍ）中間層にアルミ箔（厚み９μｍ）、最内層に特殊ポリエチレン、特殊ポリプロプレン、ナイロン−１２，ナイロン−１１，特殊ポリエステルフィルム（厚み４０〜７０μｍ）の３層構造のもの、或いは最外層にアルミ箔、最内層の３層のほかに、衝撃吸収層としてもう１層のフィルムをアルミ箔の内側、または外側に設けた４層構造のものがある。 A variable volume container suitable for use in the present invention is a laminate containing an aluminum foil that completely blocks oxygen, light, and hydrogen and prevents alteration of the water content. For example, biaxially stretched polyethylene terephthalate film (thickness 12 μm) as the outermost layer, aluminum foil (thickness 9 μm) as the intermediate layer, special polyethylene, special polyprene, nylon-12, nylon-11, special polyester film (thickness 40- 70μm), or a three-layer structure with an aluminum foil as the outermost layer and a three-layer film as the shock absorbing layer in addition to the outermost layer, the innermost layer or the outermost layer. There is.
最外層のポリエステルフィルムは、アルミ箔の腐食防止、ピンホールの保護、光沢、印刷効果等の目的で使用される。 The outermost polyester film is used for the purpose of preventing corrosion of aluminum foil, protecting pinholes, gloss, printing effect, and the like.
アルミ箔は、光、酸素、水素、水蒸気の完全バリヤー層である。最内層に使用されるプラスチックフィルムは、シール材として容器を形成するとともに、アルミ箔の腐食防止、ピンホールに対する保護皮膜として機能し、また容器の落下衝撃、振動、積圧等の強度に対して寄与する。 Aluminum foil is a complete barrier layer of light, oxygen, hydrogen, and water vapor. The plastic film used for the innermost layer forms a container as a sealing material, functions as an anticorrosion of aluminum foil, a protective film against pinholes, and against the strength of containers such as drop impact, vibration, and accumulated pressure. Contribute.
さらに、本発明は内容物が水という極めて流動性が大きな商品であるので、容器が簡単に倒れないもの、即ち、自立性があるもの、即ち、スタンディングパウチが好ましい。スタンディングパウチとしては、２軸延伸ポリエチレンテレフタレート／低密度ポリエチレン／１軸延伸ポリエチレン／アルミ箔／エチレン−酢酸ビニル共重合体、２軸延伸ナイロン／アルミ箔／ポリエチレン、２軸延伸ポリエチレンテレフタレート／１軸延伸ポリエチレン／アルミ箔／ポリプロピレン等である。これらは自立性をもたせるために、底材をヒートシールしたものである。 Furthermore, since the present invention is a commodity with extremely high fluidity, whose content is water, a container that does not easily fall over, that is, a self-supporting one, that is, a standing pouch is preferable. As a standing pouch, biaxially stretched polyethylene terephthalate / low density polyethylene / uniaxially stretched polyethylene / aluminum foil / ethylene-vinyl acetate copolymer, biaxially stretched nylon / aluminum foil / polyethylene, biaxially stretched polyethylene terephthalate / uniaxial stretch For example, polyethylene / aluminum foil / polypropylene. These are heat-sealed bottom materials in order to have self-supporting properties.
本発明に従って、加熱殺菌する条件は、８５〜１００℃で３０〜４５分間、好ましくは、８５〜９５℃で３０分間、最も好ましくは８７℃で３０分である。８０℃以下の場合、容量によって殺菌が十分でなく、１００℃以上の場合、水が変質することがあるので好ましくない。ただし、加熱温度、及び加熱時間は、水の容量等諸変動要素によて決定される。 According to the present invention, the conditions for heat sterilization are 85 to 100 ° C. for 30 to 45 minutes, preferably 85 to 95 ° C. for 30 minutes, and most preferably 87 ° C. for 30 minutes. When the temperature is 80 ° C. or lower, sterilization is not sufficient depending on the volume, and when the temperature is 100 ° C. or higher, water may be deteriorated. However, the heating temperature and the heating time are determined by various factors such as the capacity of water.
本発明の酸化還元電位が−４００ｍＶ〜−６００ｍＶ以下の水を製造するのに必須の条件ではないが、触媒を使用する場合は、シリカ系石英斑岩を担体として、その表面に還元性金属を担持させた還元触媒を使用することができる。 Although it is not an essential condition for producing water having an oxidation-reduction potential of -400 mV to -600 mV or less according to the present invention, when a catalyst is used, a reducing metal is applied to the surface of silica-based quartz porphyry. A supported reduction catalyst can be used.
本発明において、シリカ系石英斑岩を担体としてその表面に還元性金属を担持させた還元触媒を使用する場合、シリカ系石英斑岩に担持させる金属は還元性金属で、たとえば、アルカリ金属、マグネシウム、カルシウム、アルミニウム、亜鉛などの電気的陽性の大きい金属、或いは鉄（ＩＩ）、スズ（ＩＩ）、チタン（ＩＩＩ）、クロム（ＩＩ）などの低原子価状態にある金属の塩類が例示される。 In the present invention, when a reduction catalyst having a silica-based quartz porphyry as a support and a reducing metal supported on the surface thereof is used, the metal supported on the silica-based quartz porphyry is a reducing metal, such as an alkali metal, magnesium, etc. Examples thereof include salts of metals having high electrical positiveity such as calcium, aluminum, and zinc, or metals in a low valence state such as iron (II), tin (II), titanium (III), and chromium (II). .
本発明で使用する原料水は特段に限定されない。還元体、即ち［ＯＨ−］イオン、及び酸化体、即ち［Ｈ＋］イオンを含有する水、たとえば、活性化処理をしていない水道水、飲用することができる天然水等を使用することができる。いずれも、濾過、脱塩素等前処理をする。The raw water used in the present invention is not particularly limited. It is possible to use water containing a reductant, that is, [OH − ] ions and an oxidant, that is, [H + ] ions, for example, tap water that has not been activated, natural water that can be used for drinking, and the like. it can. In any case, pretreatment such as filtration and dechlorination is performed.
本発明で使用する原料水の温度は特段に限定されず、たとえば、１〜３０℃、好ましくは１０〜１５℃である。然しながら、水温は極端な高温、或いは低温でない限り採用できる。 The temperature of the raw material water used by this invention is not specifically limited, For example, 1-30 degreeC, Preferably it is 10-15 degreeC. However, the water temperature can be adopted as long as it is not extremely high or low.
本発明で使用する水素ガスの注入圧は、たとえば、０．１〜０．９５ＭＰａの範囲である。水素ガスの注入圧がこの範囲ならば、酸化還元電位は、−５５０ｍＶが確保できる。 The injection pressure of hydrogen gas used in the present invention is, for example, in the range of 0.1 to 0.95 MPa. If the injection pressure of hydrogen gas is within this range, the oxidation-reduction potential can be ensured to be −550 mV.
本発明で水素ガスの注入時間は、たとえば、１０秒〜１０分、好ましくは２〜５分の範囲である。水素ガスの注入時間がこの範囲ならば、酸化還元電位は、−５５０ｍＶが確保できる。水素ガスの注入時間が短過ぎると、電位が不安定であり、長すぎても、電位低下効果に特段の影響はなく、逆にコストを引き上げる。 In the present invention, the hydrogen gas injection time is, for example, in the range of 10 seconds to 10 minutes, preferably 2 to 5 minutes. If the injection time of hydrogen gas is within this range, the oxidation-reduction potential can be ensured to be −550 mV. If the injection time of hydrogen gas is too short, the potential is unstable. If it is too long, the potential lowering effect is not particularly affected, and the cost is increased.
