Description

Multiphase ice using electrolyzed water

Embodiments of the present invention relate to ice having a multiphase structure using electrolyzed water.

Ice is generally used to store fresh products.

In addition to this low temperature freshness preservation with ice, there is a technology that uses electrolyzed water having bactericidal properties as the water used for ice.

This is because water containing hypochlorous acid and sodium hypochlorite obtained by decomposing salt water into the water that forms ice itself is used for bactericidal effects or deodorization with hypochlorous acid and sodium hypochlorite. It has an effect.

Also, as a method for preserving other fresh products, a technique is generally used in which fresh products are sprayed with water to freeze only the surface layer.

Here again, there is a technique using electrolyzed water having bactericidal properties as the water used.

However, conventional ice can give a sterilizing function and a deodorizing function with hypochlorous acid and the like, but hypochlorous acid and sodium hypochlorite have a problem with a chlorine odor.

Also, there was a problem that the quality of fresh products and containers changed due to the pH of the dissolved water.

Hereinafter, embodiments will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a cross-sectional view illustrating an example of ice having a multiphase structure according to the first embodiment.

The ice 10 has a weight of 100 g and has a two-phase configuration of the second phase 2 in the center and the first phase 1 in the surface layer. The second phase 2 is formed with 50 g of an ascorbic acid aqueous solution containing 0.5 g of ascorbic acid per liter, and the first phase 1 is formed with 50 g of hypochlorous acid water having an effective chlorine concentration of 50 ppm. .

FIG. 2A and FIG. 2B are schematic diagrams for explaining an example of the ice manufacturing method used in the first embodiment.

First, as shown in FIG. 2A, the ascorbic acid aqueous solution 2 'is poured into an ice tray 11 having a length of 16 mm, a width of 16 mm, and a height of 20 mm to make ice.

Next, the ice 2 in the ice tray 11 is transferred to an ice tray 12 having a length 20 mm, width 20 mm, and height 25 mm larger than the ice tray 11, and the periphery of the ice 2 is supported by the support member 3, and hypochlorous acid. The ice is made by pouring water and fixing the position in the depth direction by covering the ice tray 12 with the lid 4 provided with the support member 3, and a second portion formed using an ascorbic acid aqueous solution at the center. It is possible to form an ice 10 having a laminated structure including the phase 2 and the first phase 1 formed using electrolyzed water as a surface layer. In the first phase 1 of the obtained ice 10, a groove 6 is formed at a location fixed using the support member 3.

FIG. 3 shows changes in the effective chlorine concentration of the dissolved water when the ice 10 is naturally melted.

FIG. 4 is a graph showing the relationship between the amount of ascorbic acid dissolved in 1 liter of water containing 50 ppm of hypochlorous acid and the effective chlorine concentration.

Hypochlorous acid water is generated as acidic electrolyzed water by electrolysis of salt water or the like. Hypochlorous acid has a strong sterilizing function and deodorizing function, but a unique chlorine odor is generated. Ice with hypochlorous acid water can be sterilized and deodorized with hypochlorous acid, but hypochlorous acid is stable and not decomposed even when neutralized, so the dissolved water will have a chlorine odor over a long period of time. Will occur.

On the other hand, for example, when storing fresh products, the sterilizing and deodorizing function with hypochlorous acid often has no problem even if it is lowered after acting for a desired period of time, but rather the chlorine odor should disappear.

Ascorbic acid is a substance that effectively decomposes hypochlorous acid other than bacteria.

The graph 102 in FIG. 4 shows the change in effective chlorine concentration after ascorbic acid is added to hypochlorous acid water having a concentration of 50 ppm and stirred for 1 minute. As shown in the figure, the ascorbic acid required for hypochlorous acid decomposition is not equivalent in terms of the number of molecules, but it seems that one ascorbic acid can basically decompose one hypochlorous acid over time. It is. This is thought to be because hypochlorous acid is decomposed by ascorbic acid being oxidized to hypochlorous acid.

In addition, ascorbic acid is safe for the human body and does not give off an unpleasant odor, in the embodiment, 0.5 g in 1 liter is added more than the number of hypochlorous acid molecules to form the center of ice. .

For this reason, as shown in the graph 101 of FIG. 3, the water in which the surface layer is dissolved shows an effective chlorine concentration of 50 ppm as hypochlorous acid water, but when the central portion starts to melt, the effective chlorine concentration decreases. After the time T1, the effective chlorine concentration became zero while leaving the center.

In this experiment, ice 10 was left in a foamed polystyrene box for 24 hours in an environment of 25 ° C. and 50% humidity at atmospheric pressure. Time T1 was 10 to 15 hours.

As a result, ascorbic acid remained in the water in which all the ice was dissolved, but no particular chlorine odor was felt.

The addition amount of the ascorbic acid aqueous solution can be set so that the ratio of the number of hypochlorous acid molecules to the number of molecules of ascorbic acid is 0.01 to 10. If it is less than 0.01, the acidity peculiar to ascorbic acid tends to be felt strongly, and if it exceeds 10, there is a tendency that the chlorine odor cannot be sufficiently suppressed.

Further, it is preferable to select an appropriate amount of the concentration of the ascorbic acid aqueous solution to be used in the range of 10 to 1000 ppm. For example, by changing the concentration and quantity, such as making 100 g of ice with 10 ppm ascorbic acid water and making 10 g of 50 ppm hypochlorous acid water on the outside, the change in composition due to melting shown in FIG. Can be adjusted as appropriate. If it is less than 10 ppm, there is a tendency that the effect is not sufficiently exhibited because it is too thin, and if it exceeds 1000 ppm, adjustment tends to be difficult because it is too thick.

(Second Embodiment)
FIG. 5 is a cross-sectional view illustrating an example of ice having a multiphase structure according to the second embodiment.

The ice 101 includes a first phase 1 made of acidic hypochlorous acid water ice provided on the surface layer and a second phase 5 made of alkaline sodium hydroxide aqueous ice provided in the center. And a laminated structure.

FIG. 6A and FIG. 6B are schematic diagrams for explaining an example of the ice manufacturing method used in the second embodiment.

As shown in the figure, this method is the same as the ice manufacturing method used in the first embodiment, except that the sodium hydroxide aqueous solution 5 ′ is poured into the ice tray 11 instead of the ascorbic acid aqueous solution 2 ′ to make ice. It is.

By this method, a second phase 5 formed using a sodium hydroxide aqueous solution 5 ′ instead of an ascorbic acid aqueous solution 2 ′ at the center, and a first phase 1 formed using electrolytic water as a surface layer. It is possible to form ice 101 having a laminated structure consisting of

FIG. 7 shows the pH change of the molten water when the ice 101 melts.

FIG. 8 shows an apparatus for generating hypochlorous acid water and sodium hydroxide aqueous solution used for the ice 101.

As shown in the figure, an electrolyzed water generating apparatus 50 includes an intermediate chamber 51 in which saturated saline is circulated, and an anode chamber 54 having an anode electrode 56 via ion exchange membranes 52 and 53 on the left and right sides thereof, and It has a three-chamber type electrolytic cell 58 in which a cathode chamber 55 provided with a cathode electrode 57 is arranged.

A voltage is applied to each of the anode electrode 56 and the cathode electrode 57.

The intermediate chamber 51 is connected to a saturated saline circulation system 63 including a saturated saline reservoir 61 and a salt water circulation pump 62, and a saturated saline 65 is always supplied.

The anode chamber 54 and the cathode chamber 55 are connected to a water supply system 64, and new water is always supplied.

In the anode chamber 54, chlorine ions in the intermediate chamber 51 are induced by the anode electrode 56 and chlorine gas is generated to generate hypochlorous acid water. In the cathode chamber 55, sodium ions in the intermediate chamber 51 are induced by the cathode electrode 57. At the same time, hydrogen gas is generated to produce an aqueous sodium hydroxide solution. The former is hypochlorous acid water having an effective chlorine concentration of 20 to 60 ppm and a pH of about 2 to 5, and the latter is an aqueous sodium hydroxide solution having a pH of about 10 to 13. The sodium hydroxide aqueous solution is taken out from the cathode chamber 55 through the discharge line 71 together with the generated hydrogen gas. By providing the gas-liquid separation unit 72 in the discharge line 71, hydrogen gas can be discharged from the discharge line 71 to the outside.

This hypochlorous acid water is a safe water that has an excellent bactericidal effect and is also approved for food additives. By generating ice with this hypochlorous acid water, ice useful for sterilization and preservation of seafood can be provided.

Moreover, water containing hypochlorous acid can be generated while being neutral by mixing water obtained by diluting this sodium hydroxide aqueous solution about 4 times with the above-mentioned hypochlorous acid water.

This hypochlorous acid water near neutrality has no equilibrium reaction with chlorine gas, and can greatly reduce the chlorine odor.

That is, in the ice of the second embodiment, the function of sterilization and deodorization is demonstrated by acidic hypochlorous acid water at the beginning of contact with seafood, but thereafter, the sodium hydroxide aqueous solution in the central portion is hypochlorous acid. By neutralizing the acid water and maintaining hypochlorous acid itself, the sterilization and deodorizing function can be maintained to some extent, and the generation of chlorine gas can be suppressed by the neutralization to mitigate the chlorine odor.

The amount of sodium hydroxide aqueous solution added can be set so that the ratio of the number of hypochlorous acid molecules to the number of sodium hydroxide molecules is 0.1-10. If it is less than 0.1, the sodium hydroxide component remains harmful, and it tends to be alkaline and change the color of proteins and the like. If it exceeds 10, there is a tendency that it cannot be sufficiently neutralized.

The concentration of the aqueous sodium hydroxide solution used is preferably 1 to 1000 ppm. If it is less than 1 ppm, it tends to be too thin to produce a neutralizing effect, and if it exceeds 1000 ppm, the composition tends to change abruptly, or an adverse effect due to alkalinity tends to occur.

(Third embodiment)
FIG. 9 is a schematic diagram illustrating an example of ice having a multiphase structure according to the third embodiment.

Here, the hypochlorous acid water similar to the first embodiment is sprayed on the fresh product 14 to freeze the first phase 7, and then the aqueous ascorbic acid solution similar to the first embodiment is sprayed. A two-phase frozen structure in which the second phase 8 is frozen is used.

For this reason, it is possible to exert a sterilizing and deodorizing function for fresh products and to greatly reduce the chlorine odor to the outside.

Thus, by using the laminated ice of the present invention, the sterilization function and chlorine odor can be controlled and adjusted well.

Other than that, it has the same configuration as the ice having a multiphase structure according to the first embodiment.

FIGS. 11A to 11E are schematic diagrams for explaining an example of the ice manufacturing method used in the fourth embodiment.

First, as shown in FIG. 11A, hypochlorous acid water 22 'similar to the hypochlorous acid water used in the first embodiment is poured into an ice tray 21 to make ice. At this time, the hypochlorous acid water 22 ′ is cooled from the portion in contact with the ice tray 21 and begins to freeze. Before the central portion of the hypochlorous acid water 22 ′ freezes, as shown in FIG. 11B, 40 g of hypochlorous acid water frozen along the ice tray is left, and the non-frozen hypochlorous acid water 22 is left. Remove all '. As a result, about 40 g of ice 22 having a recess 24 is obtained.

Next, as shown in FIG. 11C, an aqueous solution 23 'similar to the ascorbic acid aqueous solution used in the first embodiment is introduced into the recess 24, and ice making is performed to obtain the ice 23 filling the recess 24. At this time, the concentration of the ascorbic acid aqueous solution is 500 ppm and the amount added is 50 g.

Subsequently, as shown in FIG. 11D, hypochlorous acid water 22′10 g used for forming the ice 22 having the recess 24 is added to the ice tray 21 in which the ice 22 and the ice 23 filling the recess 24 are formed. Furthermore, by introducing and making ice as shown in FIG. 11E, as shown in FIG. 10, the center part composed of the second phase 23 formed with the ascorbic acid aqueous solution and the first formed with hypochlorous acid water are used. The ice 30 having a two-phase structure with the surface layer composed of the phase 22 is obtained.

Also, as another example of ice according to the fourth embodiment, ice produced in the process shown in FIG. 11C can be used.

FIG. 12 shows a cross-sectional view of another example of ice according to the fourth embodiment.

As shown in the figure, the ice 30 ′ produced in the step shown in FIG. 11C is composed of a first phase composed of ice 22 having a recess 24 and a second phase composed of ice 23 filling the recess 24. Since one phase does not cover the second phase, the second phase is partially exposed.

Thus, by exposing a part from the beginning, the composition change when the ice shown in FIGS. 3 and 7 melts can be changed gradually and quickly.

In the ice of the fourth embodiment, as in the ice of the first embodiment, the function of sterilization and deodorization is initially exhibited by the acidic hypochlorous acid water when it comes into contact with the first seafood. Ascorbic acid aqueous solution decomposed the hypochlorous acid water in the central part, and ascorbic acid remained in the water in which all the ice was dissolved, but there was no particular odor of chlorine.

(Fifth embodiment)
In the first to fourth embodiments, a first phase formed by freezing hypochlorous acid water and a second phase formed by freezing ascorbic acid aqueous solution or sodium hydroxide aqueous solution are provided.

This method is a modification of the fourth embodiment.

As shown in the figure, ice is made by flowing hypochlorous acid water 32 ′ similar to the hypochlorous acid water used in the first embodiment to the ice tray 31. At this time, the hypochlorous acid water 32 ′ is cooled from the portion in contact with the ice tray 31 and begins to freeze. When the side and bottom portions of the ice tray 31 are frozen to a certain thickness, for example, 1 mm, as shown in FIG. 14B, the non-frozen hypochlorous acid water 32'80g is removed. Thereby, the ice 32 which has the dent 35 is obtained.

Subsequently, as shown in FIG. 14C, the water 33 ′ is supplied to the ice 32 having the dent 35 to a depth D 2 that is sufficiently smaller than the depth D 1 of the dent 35, for example, 1 mm. When the portion is frozen to a certain thickness, for example, 2 to 3 mm, 33'30 g of water is removed. Thereby, as shown to FIG. 14D, the ice 33 which has the dent 36 is obtained.

After that, as shown in FIG. 14E, an aqueous solution 34 'similar to the ascorbic acid aqueous solution used in the first embodiment is introduced into the recess 36, and ice is made to fill the recess 36 by making ice. At this time, the addition amount of 500 ppm ascorbic acid aqueous solution was 25 g.

Subsequently, as shown in FIG. 14F, water 33′5 g used for forming the ice 33 having the dent 35 is further introduced into the ice tray 31 in which the ice 33 and the ice 34 filling the dent 36 are formed, By making ice, the periphery of the ice 34 can be covered with the ice 33.

Subsequently, as shown in FIG. 14G, by making hypochlorite water 32 ′ similar to the hypochlorous acid water used in the first embodiment into ice tray 31 to make ice, as shown in FIG. 14H. Further, the periphery of the ice 33 can be covered with the ice 32, and ice having a three-phase structure as shown in FIG. 13 is obtained.

It should be noted that the size of the ice is not limited to 100 g, and may be 10 g or 200 g. Of course, the larger the ice size, the longer it takes to melt, and the smaller the ice, the faster it melts. The amount, concentration, and composition of each phase can also be set as appropriate. The longer the amount, the longer the time for melting, and the higher the concentration, the abrupt change to the corresponding phase composition.

Subsequently, as shown in FIG. 16, the periphery of the ice 7 is supported by the support member 9, the hypochlorous acid water 1 ′ is poured, and the ice tray 13 is further moved by the lid body 41 provided with the support member 9. By making ice with the position in the depth direction fixed by covering, a second phase 2 formed using an ascorbic acid aqueous solution at the center as shown in FIG. 15 and a second phase formed from water as an intermediate layer It is possible to form an ice 50 having a three-phase structure including the third layer 7 and the first phase 1 formed using electrolyzed water as a surface layer. In the first phase 1 of the obtained ice 50, a groove 42 is formed at a location fixed using the support member 9, and the third phase 7 is formed at a location fixed using the support member 3. A groove 6 is formed.

When the third phase composed of water is interposed between the first phase and the second phase as in the fifth embodiment and the sixth embodiment, the first phase is slowly added only for the time during which the third phase is dissolved. There is an advantage that the composition can be changed so as to dilute the phase.

As described above, there may be three or more phases having different compositions, and the composition and amount of each phase can be appropriately changed depending on the situation.
