Description

  The present invention relates to a bactericidal agent and a bactericidal method, and more particularly to a bactericidal agent and a bactericidal method having excellent permeability.

  Neutral electrolyzed water, slightly acidic electrolyzed water, and weakly acidic electrolyzed water are types of hypochlorite water together with strong acid electrolyzed water, all of which are types of disinfectants approved for use as food additives. is there. Among these, in particular, slightly acidic electrolyzed water has a long shelf life of more than half a year, and since it is slightly acidic, almost all of the bactericidal components exist as molecular hypochlorous acid. Regardless of its strong bactericidal power, it produces almost no trihalomethane even when it encounters organic substances, and is a very safe bactericidal agent. Now, it is widely used in fields such as food manufacturing industry, industry, medical care, nursing care, agriculture and the like.

  Strongly acidic electrolyzed water (strongly acidic hypochlorous acid water) is strong in sterilizing power but is hardly stored, and it is easy to generate chlorine gas and is likely to corrode metals. . Also, the pH is very low at 2.7 or less, and there is a risk of alteration depending on the food. This strongly acidic electrolyzed water is an aqueous solution obtained from the anode side by electrolyzing a sodium chloride aqueous solution in a diaphragm membrane electrolytic cell.

  In addition, weakly acidic electrolyzed water (weakly acidic hypochlorous acid water) was not initially recognized as a food additive, but is now under deliberation, and a 0.2% or less sodium chloride aqueous solution is used as a diaphragm. An aqueous solution obtained from the anode side by electrolysis in an electrolytic cell. Alternatively, an aqueous solution obtained from the cathode is added to an aqueous solution obtained from the anode to adjust the pH to 2.7 to 5.0. Although bactericidal power and preservability are intermediate between strongly acidic electrolyzed water and slightly acidic electrolyzed water, the history as a food additive is short and there is little information.

  On the other hand, slightly acidic electrolyzed water (slightly acidic hypochlorous water) is an aqueous solution in which 2 to 6% hydrochloric acid is obtained in a non-diaphragm electrolyzer according to the previous standard, pH 5.0 to 6.5, effective chlorine content 10 Although it was supposed to be ˜30 mg / kg, it now refers to an aqueous solution in which an aqueous solution containing this standard and 3% or less of hydrochloric acid and 5% or less of sodium chloride is obtained in a non-diaphragm electrolyzer, pH 5. There appear to be two specifications of 0 to 6.5 and an effective chlorine content of 50 to 80 mg / kg. In the former standard, the effective chlorine content of 10 mg / kg (ppm) can be sterilized without impairing the taste and aroma of the food. Minimize this, and even if the concentration is increased, the sterilizing power will not improve. Is defined as the upper limit. Currently, it seems that both standards coexist, but in any case, the pH is 5.0 to 6.5, which is slightly acidic, and the storage stability is almost the same.

  This slightly acidic electrolyzed water does not cause the problem of chlorine odor remaining in the food, and it does not require rinsing, so it can save water and save labor, and it is safe to use without worrying about rough hands. There are many advantages such as no need to take care not to get into the eyes or eyes.

  And at present, there is almost no information about the reformation of whether there is a big problem in slightly acidic electrolyzed water. However, as shown in Patent Document 1, there is one which has an improved bactericidal effect by reducing the surface tension by adding 0.001 to 1.0% of polyether-modified silicone to slightly acidic electrolyzed water. . In addition, as shown in Patent Document 2, even when sodium bicarbonate is dissolved in water for diluting hydrochloric acid and low hardness water is used, it is not necessary to adjust the electrolysis conditions. A description of adding an alkali metal salt or an alkaline earth metal salt so as to maintain a proper pH is disclosed.

  Recently, neutral electrolyzed water has been attracting attention. This neutral electrolyzed water is electrolyzed by utilizing the chlorine ions contained in tap water, so there is no need for any additives such as salt and hydrochloric acid, and there is a simple one that does not require ventilation. Moreover, it can drain as it is during drainage. Moreover, it is effective against many bacteria and viruses such as Norovirus and avian influenza. There is a sufficient effect for about 20 days without the effect being reduced in a short time after generation. And it has an overwhelmingly high residual chlorine compared to general tap water, and the concentration is declining or gradual. In addition, running costs are basically economical with only water bills and electricity bills.

  However, when the present inventors put in a plastic bag together with slightly acidic electrolyzed water an unsterilized fine shelled shelled egg and kept it in an unheated state at a temperature of 10 ° C. or less for 14 days, Although no thickening was observed in the liquid part, some cloudiness was observed. When the number of viable bacteria and coliform bacteria were examined by the standard medium method / decoxycholate agar medium method, a large number of colonies were observed in the liquid part (not countable). The egg part was the same. It was speculated that this phenomenon occurred due to the presence of bacteria in the fine cocoons of the peeled eggs, and the slightly acidic electrolyzed water could not sterilize the bacteria in the cocoons.

An object of the present invention is to provide neutral electrolyzed water, slightly acidic electrolyzed water, and weakly acidic electrolyzed water excellent in permeability that can sterilize bacteria in such a fine and deep place.

  As the means, in the present invention, (1) generating fine micro to nano-grade air, nitrogen gas or ozone gas bubbles in neutral electrolyzed water, slightly acidic electrolyzed water or weakly acidic electrolyzed water, Or, (2) Bubbles such as fine micro to nano-grade air were generated in normal tap water (including a small amount of chlorine) or water containing diluted hydrochloric acid, hydrochloric acid / sodium chloride, or sodium chloride. (3) or after processing micro and nano bubbles in water, add a small amount of chlorine gas to this water, or add dilute hydrochloric acid, hydrochloric acid / sodium chloride, or sodium chloride to this water, Decompose. By this operation, the clusters and molecules of the neutral electrolyzed water, slightly acidic electrolyzed water, and weakly acidic electrolyzed water are made small so that the bacteria in the deep and deep cocoon can be sterilized.

  A micro / nano bubble is a fine bubble. In particular, depending on the size of the bubble diameter, those having a size up to several hundreds of nanometers are divided into nanobubbles, those having several hundreds of nanometers to several tens of μm are divided into micro-nano bubbles, and those having several tens of μm to several hundreds of μm are divided into microbubbles. In the present invention, the term “micro / nanobubble” includes all of nanobubbles, micronanobubbles, and microbubbles, and unless otherwise defined, includes not only a single state of nanobubbles, micronanobubbles, and microbubbles, but also a mixture of them. Including the state of

  Two types of devices for generating micro / nano bubbles are currently known. One is an ultra-high-speed turning system developed by Hirofumi Taisei, a professor at Tokuyama National College of Technology, who has clarified the micro / nano bubble phenomenon (M2-LM / SUS, etc. from Nano Planet Research Laboratories). This is a pressure reduction method (Asp SMX115, AS-K3, etc., Daiichi D-1, D-2, D-3, etc.).

  In the former, when a liquid pressurized by a pump is fed, a swivel motion is performed in the apparatus. Centrifugal force causes the liquid to move outward, reducing the pressure in the center and sucking in gas from the inlet. The liquid swirls around the periphery of the device, and the gas swivels around the center (400 to 600 revolutions per second). As a result of the difference in speed between the high-speed swirling gas cavity before and after the jet outlet, the air is rotationally cut. The air becomes a flat belt like round noodles, twisted, torn off, and ejected as microbubbles (fine bubbles with a diameter of 10 μm to several hundred μm or less) (see Japanese Patent No. 3397154).

  These microbubbles are thought to gradually shrink to micro-nano bubbles (several hundred to 10 μm or less) and further to nano-bubbles (several hundred nm or less) because the surrounding pressure is higher than the internal pressure. However, nanobubbles are not clearly observed at present.

  The other method is to pressurize the liquid with a pump, etc., put air into it, and forcibly dissolve the air under pressure. This liquid is transferred to a pressure relief device to generate bubbles. Small bubble nuclei grow into bubbles that look white. The size of the bubbles is larger than the former. As long as micro / nano bubbles can be generated by other methods, any method may be used. Note that the bubbles generated in each of these methods do not gather together and become large because the periphery is negatively charged.

  In the present invention, any of the above methods can be used. However, most of the following examples used the former apparatus. This is because the apparatus and operation are simple and the effect is great. In particular, the water treated in the former is said to be excellent in physiological activity, and raises the pH somewhat. Further, in the former case, the micro / nano bubble treatment is repeated to improve the permeability each time, but in the latter case, if the treatment is performed once, the effect does not seem to be changed no matter how many times the treatment is performed thereafter. It is preferable that the pH of the treatment liquid rises somewhat to lower the original pH in the case of slightly acidic electrolyzed water, and in the case of weakly acidic electrolyzed water, it can be considered that the pH is changed to slightly acidic electrolyzed water.

Conventionally, as far as the present inventors know, a technique for improving the permeability by treating slightly acidic electrolyzed water or the like with micro / nano bubbles is not known.

  Micro / nanobubbles are generated when liquid is taken into the device that generates this, and air (or nitrogen gas or ozone gas) sucked from outside the device is mixed with the liquid to form fine bubbles that are ejected from the device. To do. Therefore, micro-nano bubble generator is taken in micro acid / nano bubble generator and mixed with air to produce fine bubbles and ejected from the device (ultra-high speed swirling method, Taisei method), or micro / nano bubble generator Is mixed with air to generate fine bubbles and ejected from the apparatus (pressurization, decompression method).

In general there is a possibility that airborne bacteria and thereby generating fine air bubbles in a liquid to grow, the problem does not occur because the slightly acidic electrolyzed water or the like itself is bactericidal in the present invention.

Fibers slightly acidic electrolyzed water or the like micro-nano bubble treatment of the present invention, it is possible to use it as a normal slightly acidic electrolyzed water, there especially for permeability is excellent, food and there are fine scratches, uneven It can be sprayed or dipped in a wrinkled part such as a product or fingers to bring about a sufficient sterilizing effect. In addition, there is also an effect that the athlete's foot reaches the place where the athlete's foot is lurking under the limbs of the limbs, and the athlete's foot is almost completely cured in about 2 to 3 weeks to 1 to 3 months.

  Weakly acidic electrolyzed water is also slightly lower in pH than slightly acidic electrolyzed water and has some storage stability, and can be treated with micro / nano bubbles in the same manner as slightly acidic electrolyzed water. The same applies to neutral electric field water.

As described above, the present invention includes (1) a bactericide obtained by micro / nano bubble treatment of neutral electrolyzed water, slightly acidic electrolyzed water or weakly acidic electrolyzed water, (2) normal tap water (including a small amount of chlorine), Disinfectant obtained by electrolyzing bubbles containing water such as dilute hydrochloric acid, hydrochloric acid / sodium chloride, and sodium chloride, which generates fine micro- or nano-class air bubbles, (3) or micro After the nanobubble treatment, a small amount of chlorine gas is added to this water, or dilute hydrochloric acid, hydrochloric acid / sodium chloride or sodium chloride is added to this water, and these are electrolyzed, and all have excellent permeability.
Therefore,
(1) A bactericidal agent having excellent permeability to foods and the like can be produced by a simple operation. The effect lasts about half a month to one month.
(2) Even if the food has wrinkles, irregularities, and fine scratches, the bactericidal agent penetrates into the wrinkles and scratches even if it is not heated, so that sterilization is sufficiently performed and energy is saved.
(3) It penetrates well into uneven fabrics and keratinous parts of the skin to bring about a bactericidal effect.
(4) Even if the treated neutral electrolyzed water, slightly acidic electrolyzed water, or slightly acidic electrolyzed water is heated, the permeability effect thereof does not change. The effect of the micro / nano bubble treatment lasts about half a month to one month or more.
There are effects such as.

Example 1 It is explanatory drawing of a pressurization pressure reduction system. Example 1 A shelled cocoon with fine cocoons is used to put the liquid into a plastic bag together with eggs (10 pieces) and stored for 14 days at a temperature of 10 ° C. or less in an unheated state.

  Sterilize by using slightly acidic electrolyzed water that has been treated with a micro / nano bubble generator in shelled eggs with fine shells. EXAMPLES Hereinafter, although this invention is demonstrated concretely based on an Example and a comparative example, this invention is not limited to these Examples.

(Micro / nano bubble treatment of slightly acidic electrolyzed water)
FIG. 1 is an explanatory diagram of an ultra-high speed swirling method (Daisei) device, FIG. 2 is an example of a micro / nano bubble processing device (test machine) using the micro bubble generating device of FIG. 1, and FIG. It is explanatory drawing (Corporation | KK Dainichi Kogyo) of an apparatus. The case where micro / nano bubble treatment is performed on slightly acidic electrolyzed water using these apparatuses will be described. In the present invention, the experiment was mainly performed using the apparatus shown in FIG.

  FIG. 1 is a principle diagram for generating microbubbles. First, when a liquid (slightly acidic electrolyzed water) 2 applied with pressure by a pump 1 is fed into a microbubble generator 3, the liquid 2 performs a swiveling motion in the apparatus 3. To do. Inside the device 3, the liquid 2 is moved outward by centrifugal force, so that the pressure in the central portion is reduced and the gas 5 is sucked from the air inlet 4 (self-priming). The liquid and the gas swirl within the device 3. The number of revolutions is 400 to 600 revolutions per second. The liquid 2 swirls around the outer periphery of the apparatus, and the gas 5 swirls at the center at an ultra high speed. As a result of the difference in speed between before and after the jetting of the gas cavity that turns at a high speed, the gas is rotationally cut and becomes microbubbles that are jetted from the outlet 6 of the apparatus 3. Microbubbles are thought to shrink to nanobubbles when pressed by ambient pressure.

  FIG. 2 shows a small micro / nano bubble processing apparatus (hereinafter referred to as a nano processing apparatus or test machine) 10 that can process about 5 L of slightly acidic electrolyzed water using the micro bubble generating apparatus 3 of FIG. This processing apparatus 10 connects a tank 2A and a pump 1 with a water absorption pipe 1A and a water supply pipe 1B, the tip of the water supply pipe 1B is connected near the tip of the microbubble generator 3, and the base of the microbubble generator 3 is connected to the base of the microbubble generator 3. The air supply pipe 4A is connected. When liquid (slightly acidic electrolyzed water) is sent to the microbubble generator 3 by the pump 1, the air 5 is sucked from the intake port 4, stirred with the slightly acidic electrolyzed water 2, and microbubbles MB are ejected from the outlet 6. In the figure, 2B is a liquid level. In the following example (swivel method), the slightly acidic electrolyzed water was nano-treated using the apparatus 10 shown in FIG.

  The microbubble generator 3 used for the experiment has a diameter of 50 mm and a length of about 100 mm, and can process a liquid of about 1 to 10 L. When the amount of the processing liquid is as large as 100 to 500 L, a plurality of apparatuses (about 4 to 6) are required. Nitrogen gas or ozone gas may be used instead of air.

  FIG. 3 shows an example of a pressurizing / depressurizing apparatus. This is shown in FIG. 1 of Japanese Patent Application Laid-Open No. 2010-22955 by Dainichi Industry Co., Ltd. This device 7 is a device that pressurizes in a first pressurizing tank 8A and a second pressurizing tank 8B to dissolve gas (air) in a liquid and then returns to normal pressure in a decompression unit 9 to generate microbubbles. It is. Various types of apparatuses of this type have been proposed, and the apparatus shown in FIG. 3 is an example.

  Nano-treatment of slightly acidic electrolyzed water is performed using the apparatus of FIG. This apparatus is a test machine capable of treating slightly acidic electrolyzed water of about 5 L at a tank capacity of about 8 L at a time. In the case of the microbubble generator 3, about 5 L of slightly acidic electrolyzed water can be treated per minute (if 5 L of slightly acidic electrolyzed water can be processed once per minute). Then, when 5 L of slightly acidic electrolyzed water is treated for 20 to 30 minutes, it is treated for about 20 to 30 revolutions. Thus, microbubbles and nanobubbles are sufficiently generated in the slightly acidic electrolyzed water. Even if it is processed for 2 hours under the same conditions, the effect does not change much.

(Disinfection of fungicides into cocooned shelled eggs)
FIG. 4 shows that 10 pieces (5 pieces in the figure) of 12 shelled eggs (seven cocoons 12a) in 7 parts are placed in 1 L of liquid in a bag 11 and heated at 10 ° C. The state stored at the following temperature is shown. And (a) used the well water 13 as a liquid, (b) used the slightly acidic electrolyzed water 14 as a liquid, (c) used what carried out the micro-nano bubble process of the slightly acidic electrolyzed water. The number of bacteria was examined for the number of viable bacteria and coliform bacteria by the standard medium method and the denticolate agar medium method.

  Both (a), (b) and (c) in the figure show the state after 14 days from storage. First, in (a), the well water 13 had a cloudy portion 13a in the sensory test, and thickened. In the bacterial count results, a large amount of colony formation was observed in both the liquid part and the egg part (uncountable). (B) In the slightly acidic electrolyzed water 14, the liquid part was slightly cloudy 14a in the sensory test, but it was not as well as the well water. There was no thickening of the liquid part. In the bacterial count results, a large amount of colony formation was observed in the liquid part and the egg part (not countable), although not as well as in the well water. It was speculated that this phenomenon occurred due to the presence of bacteria in the fine cocoons of the peeled eggs, and the slightly acidic electrolyzed water could not sterilize the bacteria in the cocoons.

On the other hand, the slightly acidic electrolyzed water 15 treated with micro / nano bubbles in (c) was colorless and transparent without turbidity of the liquid part in the sensory test. In the bacterial count results, no colony formation was observed in either the liquid part or the egg part. In addition, the bacterial count result of the egg part was obtained by crushing the egg. (Table 1)

  Normally, the shelled eggs are shipped and stored in a bag-free product, and the bags are sterilized by heating and refrigerated. Therefore, the liquid does not change much for about 10 days, but it becomes cloudy after that. And, slightly acidic electrolyzed water is rarely used due to cost.

  On the other hand, in the present invention, a peeled egg with a wrinkle was selected, and the liquid and egg were packed in a bag without heating and stored at 10 ° C. or less, but the liquid was colorless and transparent even after 10 days. No colonies were observed. In contrast, conventional slightly acidic electrolyzed water and well water showed cloudiness and thickness in the liquid, and the bacterial count results were infinite (Table 1).

  This was presumed to be the result of sterilization by penetrating into the deep and deep eggs of the eggs because of the excellent permeability of the bactericide of the present invention (slightly acidic electrolyzed water treated with micro / nano bubbles). . In the case of the present invention, energy and labor can be saved because heat sterilization is not required.

(Treatment of athlete's foot)
Athlete's foot disease is a disease caused by ringworm fungus that settles in the stratum corneum and epidermis of the limbs, and the fungus itself is weak but has a difficulty that cannot be completely cured. However, the slightly acidic electrolyzed water treated with micro / nano bubbles of the present invention has good permeability, and can be completely cured in 1 to 2 weeks to 1 to 3 months by spraying, applying, or immersing the affected area. End up. It's okay if you forget the procedure from time to time.

(Deodorizing work clothes sweatiness)
The work clothes worn for a while give rise to a so-called sweaty smell that germs settle and grow in sweat and dirt. When slightly acidic electrolyzed water was sprayed on the work clothes, it smelled somewhat, but it still remained. Therefore, when this micro-acid electrolyzed water subjected to micro / nano bubble treatment was sprayed, sweatiness was deodorized cleanly.

  FIG. 5 shows a micro / nano bubble processing apparatus (test plant) in which the micro / nano bubble processing apparatus 10 of FIG. 2 is finished to be movable. In this processing apparatus 40, a pump 42 and a tank 43 are installed on a carriage 41, and the pump 42 and the tank 43 are connected by a water absorption pipe 44 and a drain pipe 45. The tip of the drain pipe 45 is connected to the front side of the microbubble generator 3, and an air hose 46 is connected to the base of the microbubble generator 3. The base of the air hose 46 is connected to the air filter 47. Reference numeral 48 is an operation panel, and 49 is a caster. Moreover, the code | symbol 50 is a taking-out port for taking out the processed slightly acidic electrolyzed water. This apparatus 40 can process about 20 L of slightly acidic electrolyzed water. However, it takes one hour and one and a half hours to sufficiently treat 20 L of slightly acidic electrolyzed water. In such a case, the processing time can be shortened to 1/2 to 1/4 by increasing the number of microbubble generators 3 to about 2 to 4 for processing. In that case, it is necessary to increase the number of pumps. A considerable amount of heat is generated during nano-processing. Therefore, it is preferable in terms of quality maintenance to prevent the temperature of the slightly acidic electrolyzed water from rising by making the tank 43 have a double structure or the like and flowing cooling water.

  When a large amount of slightly acidic electrolyzed water is required industrially, a tank having a capacity of several hundred L or more may be used. In that case, the number of microbubble generators 3 and pumps corresponding to the capacity of the slightly acidic electrolyzed water to be treated, such as 10 to 20 or more, are required.

  Using the apparatus of FIG. 2, neutral treatment of neutral electrolyzed water was performed in the same manner as in Example 1. The obtained nano-processed neutral electrolyzed water was put in the bag 11 shown in FIG. 4 of Example 2 and similarly shelled eggs (with fine scratches 12a) were put and tested in the same manner. The neutral electrolyzed water did not melt the liquid part, but by the number of bacteria, a large number of colonies were observed in both the liquid part and the egg part (not countable). In this case, as in the case of the slightly acidic electrolyzed water, the bacteria are present in the fine cocoon of the peeled egg, and it is assumed that the neutral electrolyzed water could not sterilize the bacteria in this cocoon. The The nano-treated neutral electrolyzed water was colorless and transparent and no bacterial colonies were observed even after 10 days, as with the nano-treated slightly acidic electrolyzed water.

  Next, normal tap water (including a small amount of chlorine) or water with dilute hydrochloric acid, hydrochloric acid / sodium chloride, or sodium chloride added to produce bubbles such as fine micro to nano-grade air. By carrying out electrolysis, the bactericidal agent excellent in permeability of the present invention can be obtained. For example, in the case of slightly acidic electrolyzed water, fine micro / nano bubbles are generated in water to which dilute hydrochloric acid or the like is added. The water in which the micro / nano bubbles are generated is obtained by electrolysis according to a conventional method. The obtained neutral electrolyzed water, slightly acidic electrolyzed water and weakly acidic electrolyzed water became a disinfectant excellent in permeability equivalent to the slightly acidic electrolyzed water obtained in Example 2.

  Furthermore, after treating micro water and micro bubbles in water, a small amount of chlorine gas was added to this water, or dilute hydrochloric acid, hydrochloric acid / sodium chloride, and sodium chloride were added to this water, and these were electrolyzed. Similarly, neutral electrolyzed water, slightly acidic electrolyzed water, and weakly acidic electrolyzed water exhibiting excellent permeability were obtained. Of these, the slightly acidic electrolyzed water was subjected to the same test on the shelled eggs in the same manner as in Example 2, but showed an excellent antibacterial effect as well.

  (1) By performing micro / nano bubble treatment (nano treatment) of neutral electrolyzed water, slightly acidic electrolyzed water or weakly acidic electrolyzed water, or (2) normal tap water (including a small amount of chlorine), dilute hydrochloric acid or hydrochloric acid / By further electrolyzing water with added sodium chloride or sodium chloride and generating bubbles such as fine micro to nano-class air, (3) or fine micro / nano bubbles in water After treatment, a small amount of chlorine gas is added to this water, or dilute hydrochloric acid, hydrochloric acid / sodium chloride, and sodium chloride are added to this water, and these are electrolyzed to make these disinfectants permeable to various sterilization objects. A large amount of neutral electrolyzed water, slightly acidic electrolyzed water or weakly acidic electrolyzed water including the food industry, such as sterilization of foods that can be made large and thin and narrow, without sterilization by heating. Impact on the industry to be used are those large made.
