Description

【０００１】
【産業上の利用分野】
本発明は、食塩水を電解して、弱酸性または略中性の殺菌用処理液を製造する殺菌用処理液の製造方法に関する。
【０００２】
【従来の技術】
隔膜にて区画したアノード室およびカソード室を有する電解槽にて食塩水を電解すると、アノード室側からは酸性の生成水（アノード室側生成水）が得られるとともに、カソード室側からはアルカリ性の生成水（カソード室側生成水）が得られることは、特公平４−４２０７７号公報に例示されているようによく知られている技術である。酸性のアノード室側生成水は殺菌作用を有し、またアルカリ性のカソード室側生成水は魚介類に対する色合いの悪変防止作用、ドリツプの発生防止作用、野菜類の色合いの悪変防止作用を有することから、これらの各生成水は生鮮魚介類、生鮮野菜等の食物用処理液としてそれぞれ単独で使用されている。
【０００３】
【発明が解決しようとする課題】
ところで、これら各生成水のうちアノード室側生成水は殺菌作用が高い反面酸化作用が強く、処理すべき食物によっては色素が酸化されて、表面が褐色を呈する等の変色を生じるおそれがある。また、カソード室側生成水は殺菌作用がほとんどなく、殺菌効果を期待することはできない。従って、本発明の目的は、食塩水を電解することにより、次亜塩素酸または次亜塩素酸のナトリウム塩を含む弱酸性または略中性の殺菌用処理液を製造し、被処理物を同殺菌用処理液にて処理することにより、被処理物を変色させることなく殺菌処理することにある。
【０００４】
【課題を解決するための手段】
本発明は、食塩水を電解して弱酸性または略中性の殺菌用処理液を製造する殺菌用処理液の製造方法であり、その第１の製造方法は、先づ、食塩水を隔膜にて区画されたアノード室およびカソード室を有する第１の電解槽にて電解し、次いで、第１の電解槽のアノード室にて生成された強酸性のアノード室側生成水を、アノード室およびカソード室が区画されていない第２の電解槽にて電解して弱酸性または略中性の電解生成水に生成することを特徴とするものであり、その第２の製造方法は、先づ、水を隔膜にて区画されたアノード室およびカソード室を有する第１の電解槽にて電解し、次いで、第１の電解槽のアノード室にて生成された強酸性のアノード室側生成水に食塩または食塩水を添加して、その後、食塩含有の前記アノード室側生成水を、アノード室およびカソード室が区画されていない第２の電解槽にて電解して弱酸性または略中性の電解生成水に生成することを特徴とするものである。
【０００６】
【発明の作用・効果】
本発明の製造方法において上記した第１の製造方法によれば、第１の電解槽での電解によりアノード室に次亜塩素酸または次亜塩素酸ナトリウムを含む強酸性の生成水が得られる。このアノード室側生成水は相当の殺菌作用を備えている。また、これに引続きなされる第２の電解槽での電解により上記したアノード室側生成水が弱酸性化または中性化され、同第２の電解槽では次亜塩素酸または次亜塩素酸ナトリウムを含む弱酸性または中性の電解生成水が得られる。
【０００７】
また、本発明の第２の製造方法によれば、第２の電解槽では第１の電解槽での電解にて生成されたアノード室側生成水に食塩を含有させた食塩含有の酸性水を電解するものであることから、同第２の電解槽での電解でも次亜塩素酸または次亜塩素酸ナトリウムを含む弱酸性または中性の電解生成水が得られる。従って、これらの製造方法で得られた電解生成水は殺菌作用を有するとともに、被処理物の殺菌処理において同被処理物の色素を酸化させてその表面を変色させるようなことはない。これらの電解生成水において、食塩がわずかに残存している場合には、食塩も酸化による色素の変色を阻害すべく機能を有する。
【０００９】
【実施例】
以下本発明の実施例を図面に基づいて説明するに、図１には本発明の第１実施例に係る殺菌用処理液の製造装置（第１製造装置）が示されている。第１製造装置１０は食塩水の貯溜槽１１、第１電解槽１２、第２電解槽１３、および貯溜タンク１４を備えている。貯溜槽１１は０．０５〜０．１５重量％という希薄な食塩水が貯溜される。第１電解槽１２は隔膜１２ａと一対の電極１２ｂ，１２ｃとを備え、隔膜１２ａにて区画された各室に各電極１２ｂ，１２ｃが配設されており、各室をアノード室Ｒａとカソード室Ｒｃとに区画している。これら各室Ｒａ，Ｒｃには貯溜槽１１から希薄食塩水が供給される。第２電解槽１３は一対の電極１３ａ，１３ｂを備えている。この第２電解槽１３においては、第１電解槽１２が有する隔膜１２ａに相当する隔膜を備えておらず、アノード室Ｒａとカソード室Ｒｃとは形成されていない。貯溜タンク１４には第１電解槽１２のアノード室側生成水が供給され、アノード室側生成水は貯溜タンク１４で一旦貯溜された後に同タンク１４から第２電解槽１３に供給され、また各電極１３ａ，１３ｂには直流電圧または交流電圧のいずれかが印加される。
【００１０】
第１製造装置１０を使用して殺菌用処理液を製造するには、第１電解槽１２での食塩水の電解を完了させて、アノード室側生成水を第２電解槽１３にて再度電解するか、または、必要により、第１電解槽１２での電解を完了させることなく、アノード室側生成水にわずかに食塩水を残存させた状態で第２電解槽１３で電解する。かかる条件を得るには、比較的高い濃度の希薄食塩水を採用する手段、第１電解槽１２での食塩水の流速を早くする手段、またはこれら両手段を併用する手段等による。なお、アノード室側生成水には、第１電解槽１２と第２電解槽１３間の貯溜タンク１４内で食塩または食塩水を添加する手段を採用することができ、このような手段を採用する場合には、アノード室側生成水に食塩水を残存させる必要はない。
【００１１】
かかる製造条件を採用した場合には、食塩水は第１電解槽１２では下記のごとく反応して、アノード室Ｒａからは次亜塩素酸（ＨＣｌＯ）を含む酸性の生成水が得られ、またカソード室Ｒｃからは水酸化ナトリウム（ＮａＯＨ）を含むアルカリ性の生成水が得られる。当該製造方法においては、第１電解槽１２のアノード室Ｒａ側の酸性の生成水を第２電解槽１３へ供給して再度電解させるものであり、カソード室Ｒｃの側生成水は別途採取されて従来と同様の処理液として使用される。

第２電解槽１３へ供給されたアノード室側生成水は、わずかに食塩水を残存する場合には同電解槽１３においてはアノード側でさらに次亜塩素酸が生成されるが、同電解槽１３内にて弱酸性または中性化される。従って、当該電解生成水は、次亜塩素酸および／または次亜塩素酸ナトリウムを含む弱酸性または中性の電解生成水となり、弱酸性または中性で相当程度の殺菌力を有するものとなる。
【００１３】
図２には、本発明の第２実施例に係る殺菌用処理液の製造装置（第２製造装置）が示されている。第２製造装置２０は第１製造装置１０における食塩水の貯溜槽１１が省略されているとともに、これに換えて濃食塩水の貯溜タンク２５を備えており、その他の構成は第１製造装置１０と同様である。従って、第２製造装置２０のその他の構成については、第１製造装置１０と同一の構成部材については２０番台の類似の符号を付してその詳細な説明を省略する。しかして、第２製造装置２０においては、第１電解槽２２のアノード室Ｒａおよびカソード室Ｒｃに市水がそれぞれ直接供給されて電解されるもので、アノード室側生成水は貯溜タンク２４に供給されて貯溜され、貯溜する間に貯溜タンク２５から食塩水が添加され、所定濃度の食塩を含有する酸性水に調製される。この食塩含有の酸性水は第２電解槽２３へ供給されて電解される。
【００１４】
食塩含有の酸性水が供給された第２電解槽２３においては、アノード側で次亜塩素酸が生成され、この次亜塩素酸と水酸化ナトリウムとが反応して次亜塩素酸ナトリウムが生成されるとともに酸性が中和される。従って、第２電解槽２３での電解生成水は、次亜塩素酸および／または次亜塩素酸ナトリウムを含む弱酸性または中性の電解生成水となり、弱酸性または中性で相当程度の殺菌力を有するものとなる。
【００１５】
下記の表１には、本発明の第１製造装置１０を使用して電解生成水の生成実験を行った場合の実験結果を示している。また、下記の表２には、表１に示す本発明の第１製造装置１０の第２電解槽１３での電解生成水（本発明の電解生成水）と、従来の製造装置（第１電解槽のみを備えた製造装置）で得たアノード室側生成水（従来のアノード室側生成水）と、市販の次亜塩素酸ナトリウムにて調製した殺菌用処理水水（市販試薬による調製水）の３種類を用いて、野菜である大葉を殺菌処理実験を行った場合の実験結果を示している。
【００１６】
なお、本発明の電解生成水の生成実験では、貯溜タンク１１内の食塩の濃度を０．１０重量％に調製し、第１電解槽１２での電解電流値および電解電圧値を４Ａ、５Ｖとし、第２電解槽１３での電解電流値および電解電圧値を１２Ａ、４Ｖとした。また、従来の製造装置を使用した場合は、第１電解槽へ供給される食塩水の濃度を０．１０重量％に調製するとともに、第１電解槽での電解電流値および電解電圧値を１５Ａ、１０Ｖとしてた。

これらの実験結果を参照すると、殺菌処理では従来のアノード室側生成水が最も効果があり、次いで本発明による電解生成水の順であるが、従来のアノード室側生成水で処理した大葉には局部的に褐色が発生している部分が認められた。しかしながら、本発明による電解生成水ではこのような変色は認められなかった。この結果は、野菜類の緑色はクロロフィル系色素のよるものであるが、この色素がｐＨの影響により不安定になって褐色に変色するものと考えられ、ｐＨ３前後を境としてその作用がかなり弱まるものと推定される。

[Industrial applications]
The present invention is to electrolyze brine, relates to a weakly acidic or production how the sterilizing treatment liquid to produce a sterilizing treatment liquid substantially neutral.
[0002]
[Prior art]
When a saline solution is electrolyzed in an electrolytic cell having an anode compartment and a cathode compartment partitioned by a diaphragm, acidic product water (anode compartment-side product water) is obtained from the anode compartment side, and alkaline produced water is obtained from the cathode compartment side. Producing generated water (cathode chamber side generated water) is a well-known technique as exemplified in Japanese Patent Publication No. 4-42077. Acidic anode-room generated water has a bactericidal effect, and alkaline cathode-room-side generated water has an effect of preventing the color change of fish and shellfish, preventing the occurrence of dripping, and a function of preventing the color change of vegetables. Therefore, each of these generated waters is used alone as a food processing liquid for fresh fish and shellfish, fresh vegetables, and the like.
[0003]
[Problems to be solved by the invention]
By the way, among the produced waters, the produced water on the anode chamber side has a high bactericidal action, but has a strong oxidizing action, and depending on the food to be treated, the pigment may be oxidized, and discoloration such as a brownish surface may occur. Further, the generated water on the cathode chamber side has almost no bactericidal action, and no bactericidal effect can be expected. Accordingly, an object of the present invention is to produce a slightly acidic or almost neutral sterilizing treatment solution containing hypochlorous acid or sodium salt of hypochlorous acid by electrolyzing a saline solution, and treating the object to be treated. An object of the present invention is to perform a disinfection treatment without discoloring an object to be treated by treating with a treatment liquid for disinfection.
[0004]
[Means for Solving the Problems]
The present invention is a process for the manufacture of sterilizing treatment liquid saline to electrolysis to produce the sterilizing treatment liquid weakly acidic or substantially neutral, first manufacturing method thereof, ahead Dzu, a saline diaphragm anode compartment partitioned Te and electrolyzed at a first electrolytic cell having a cathode compartment, then the anode chamber side generated water generated in the strongly acidic at the anode chamber of the first electrolytic cell, the anode chamber and a cathode chambers are those characterized in that the generating the electrolyzed water of weakly acidic or substantially neutral by electrolysis in a second electrolytic bath that is not partitioned, the second manufacturing method, previously Dzu, water the electrolysis in the first electrolytic cell having an anode compartment and a cathode compartment partitioned by a diaphragm, then brine strongly acidic anode chamber side water produced in the anode chamber of the first electrolytic bath or the brine was added, then the anode chamber side of salt-containing Narusui the one in which the anode chamber and the cathode chamber and generating the electrolyzed water of weakly acidic or substantially neutral by electrolysis in a second electrolytic bath that is not partitioned.
[0006]
[Action and Effect of the Invention]
According to the above-described first production method in the production method of the present invention, strongly acidic product water containing hypochlorous acid or sodium hypochlorite is obtained in the anode chamber by electrolysis in the first electrolytic cell. The water generated on the anode chamber side has a considerable bactericidal action. Further, by the subsequent electrolysis in the second electrolytic cell, the water produced on the anode chamber side is weakly acidified or neutralized. In the second electrolytic cell, hypochlorous acid or sodium hypochlorite is added. And a slightly acidic or neutral electrolytically produced water containing
[0007]
Further, according to the second production method of the present invention, in the second electrolytic cell, the anode-room-side generated water generated by the electrolysis in the first electrolytic cell is made of a salt-containing acidic water containing sodium chloride. Since the electrolysis is performed, weakly acidic or neutral electrolyzed water containing hypochlorous acid or sodium hypochlorite is obtained also in electrolysis in the second electrolytic cell. Therefore, the electrolyzed water obtained by these production methods has a bactericidal action, and does not oxidize the pigment of the object during disinfection of the object and discolor the surface thereof. When a small amount of salt remains in these electrolytically produced waters, the salt also has a function of inhibiting discoloration of the dye due to oxidation.
[0009]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an apparatus (first manufacturing apparatus) for producing a sterilizing treatment liquid according to a first embodiment of the present invention. The first manufacturing apparatus 10 includes a storage tank 11 for saline solution, a first electrolytic tank 12, a second electrolytic tank 13, and a storage tank 14. The storage tank 11 stores a dilute salt solution of 0.05 to 0.15% by weight. The first electrolytic cell 12 includes a diaphragm 12a and a pair of electrodes 12b and 12c. Each electrode 12b and 12c is disposed in each of the chambers defined by the diaphragm 12a. Rc. Dilute saline is supplied from the storage tank 11 to these chambers Ra and Rc. The second electrolytic cell 13 has a pair of electrodes 13a and 13b. The second electrolytic cell 13 does not have a diaphragm corresponding to the diaphragm 12a of the first electrolytic cell 12, and the anode chamber Ra and the cathode chamber Rc are not formed. The generated water on the anode chamber side of the first electrolytic cell 12 is supplied to the storage tank 14. The generated water on the anode chamber side is temporarily stored in the storage tank 14 and then supplied from the tank 14 to the second electrolytic cell 13. Either a DC voltage or an AC voltage is applied to the electrodes 13a and 13b.
[0010]
In order to manufacture the sterilizing treatment liquid using the first manufacturing apparatus 10, the electrolysis of the saline solution in the first electrolysis tank 12 is completed, and the generated water in the anode chamber is electrolyzed again in the second electrolysis tank 13. Alternatively, if necessary, electrolysis is performed in the second electrolytic cell 13 with the saline solution remaining slightly in the anode chamber-side generated water without completing the electrolysis in the first electrolytic cell 12. In order to obtain such a condition, a means for employing a relatively high-concentration diluted saline solution, a means for increasing the flow rate of the saline solution in the first electrolytic cell 12, a means for using both of these means and the like are used. It should be noted that a means for adding salt or a saline solution to the anode chamber-side generated water in the storage tank 14 between the first electrolysis tank 12 and the second electrolysis tank 13 can be adopted, and such a means is employed. In this case, it is not necessary to leave the saline solution in the anode chamber side generated water.
[0011]
When such manufacturing conditions are adopted, the saline solution reacts in the first electrolytic cell 12 as described below, so that acidic product water containing hypochlorous acid (HClO) is obtained from the anode chamber Ra, and the cathode water is produced. From the chamber Rc, alkaline generated water containing sodium hydroxide (NaOH) is obtained. In this manufacturing method, the acidic generated water on the anode chamber Ra side of the first electrolytic cell 12 is supplied to the second electrolytic cell 13 for electrolysis again, and the generated water on the cathode chamber Rc side is separately collected. It is used as the same processing solution as before.
[0012]
Anode chamber Ra side 2Cl − → Cl 2 + 2e −
Cl 2 + H 2 O → H + + Cl - + HClO
Cathode compartment Rc side 2Na + + 2H 2 O + 2e - → 2NaOH + H 2
In the anode chamber-side generated water supplied to the second electrolytic cell 13, if a slight amount of saline solution remains, hypochlorous acid is further generated on the anode side in the electrolytic cell 13. It is weakly acidic or neutralized within. Therefore, the electrolyzed water becomes a weakly acidic or neutral electrolyzed water containing hypochlorous acid and / or sodium hypochlorite, and becomes a weakly acidic or neutral water and has a considerable degree of sterilizing power.
[0013]
FIG. 2 shows an apparatus (a second apparatus) for producing a sterilizing treatment liquid according to a second embodiment of the present invention. The second manufacturing apparatus 20 is different from the first manufacturing apparatus 10 in that the storage tank 11 of the salt solution in the first manufacturing apparatus 10 is omitted, and instead the storage tank 25 of the concentrated salt solution is provided. Is the same as Therefore, for the other components of the second manufacturing apparatus 20, the same components as those of the first manufacturing apparatus 10 are denoted by similar reference numerals in the 20's, and detailed description thereof will be omitted. In the second manufacturing apparatus 20, city water is directly supplied to the anode chamber Ra and the cathode chamber Rc of the first electrolytic cell 22, respectively, to be electrolyzed. The generated water on the anode chamber side is supplied to the storage tank 24. During storage, a saline solution is added from the storage tank 25 to prepare acidic water containing a predetermined concentration of sodium chloride. The acidic water containing salt is supplied to the second electrolytic cell 23 to be electrolyzed.
[0014]
In the second electrolytic cell 23 to which the acidic water containing salt is supplied, hypochlorous acid is generated on the anode side, and the hypochlorous acid reacts with sodium hydroxide to generate sodium hypochlorite. And the acidity is neutralized. Therefore, the electrolyzed water in the second electrolyzer 23 becomes a weakly acidic or neutral electrolyzed water containing hypochlorous acid and / or sodium hypochlorite, and is slightly acidic or neutral and has a considerable sterilizing power. It becomes what has.
[0015]
Table 1 below shows the results of an experiment in which the first production apparatus 10 of the present invention was used to perform an electrolytic water production experiment. Further, in Table 2 below, the electrolytically produced water (the electrolytically produced water of the present invention) in the second electrolytic cell 13 of the first production apparatus 10 of the present invention shown in Table 1 and the conventional production apparatus (the first electrolytically produced water) are shown. Water produced by the anode chamber side (conventional anode chamber-side generated water) obtained by the production apparatus having only a tank, and treated water for sterilization prepared with commercially available sodium hypochlorite (water prepared by a commercially available reagent). 3 shows the results of experiments when a large leaf, which is a vegetable, was subjected to a sterilization treatment experiment using the three types.
[0016]
In the experiment for producing electrolyzed water of the present invention, the concentration of salt in the storage tank 11 was adjusted to 0.10% by weight, and the electrolysis current value and electrolysis voltage value in the first electrolysis tank 12 were set to 4 A and 5 V. The electrolysis current value and electrolysis voltage value in the second electrolysis tank 13 were 12 A and 4 V. When a conventional production apparatus is used, the concentration of the saline solution supplied to the first electrolytic cell is adjusted to 0.10% by weight, and the electrolytic current value and the electrolytic voltage value in the first electrolytic cell are adjusted to 15 A. , And 10V.

With reference to these experimental results, in the sterilization treatment, the conventional anode chamber-side generated water is the most effective, and then in the order of the electrolytically generated water according to the present invention. A part where brown color was locally observed was observed. However, such discoloration was not observed in the electrolytically produced water according to the present invention. The result is that the green color of vegetables is due to the chlorophyll pigment, which is considered to be unstable due to the effect of pH and turn brown, and its effect is considerably weakened around pH 3 It is presumed that.
