Description

  The present invention relates to ozone ice in which ozone is confined in ice and an ozone ice package that contains the ozone ice.

  When transporting fresh food, etc., it is necessary to maintain the freshness of fresh food, etc. while transporting, so that it does not corrode fresh food, etc. There is a risk that the freshness will drop or the fresh food will be corroded. Therefore, conventionally, in the transportation of fresh foods and the like, ozone that has excellent sterilizing power and deodorizing power and is non-polluting has been actively used.

  Conventionally, ozone is generated by a discharge method, electrolysis, an ultraviolet lamp method, etc., but all the generation methods are complicated, requiring large-scale equipment or accompanied by significant power consumption. It was. Moreover, since the produced | generated ozone is an unstable compound, it was reduce | restored to oxygen immediately and it was difficult to store ozone.

  In order to solve such a problem, ozone ice generated by freezing high-concentration ozone water has been proposed, and such ozone ice easily releases ozone by melting the ozone ice. Therefore, it is used for the purpose of ozone sterilization and ozone deodorization.

  However, conventional ozone ice can be sterilized, deodorized, etc. by the release of ozone as the ozone ice melts, but is generated by the dissolution of ozone ice. There is a problem that ozone released from ozone ice is dissolved again in dissolved water.

  In addition, conventional ozone ice is used by storing ozone ice obtained by freezing ozone water in a water-impermeable bag, but even in such a bag, water can permeate. For example, when ozone ice is used in the transportation of fresh food, etc., the dissolved water produced by the dissolution of ozone ice adheres to the fresh food, etc. There is a problem that will be damaged.

  In view of such a problem, the present invention is capable of preventing ozone released from ozone ice from being dissolved again in ozone ice dissolved water, and the ozone ice dissolved water leaking out. An object of the present invention is to provide an ozone ice package capable of preventing the above.

The gelling agent can be brought into contact with the dissolved water of ozone ice, and the dissolved water of ozone ice can be gelled.

  In the said invention (invention 1-4), it is preferable that the film thickness of the said capsule is 80-100 micrometers (invention 5). If it takes a long time for the capsule to come into contact with the dissolved ozone ice water (for example, more than 10 minutes), the ozone released from the ozone ice may be dissolved again in the dissolved ozone ice water. However, according to this invention (invention 5), the time required for the capsule to dissolve after contacting with the dissolved water of ozone ice can be shortened because the film thickness of the capsule is within the above range. (For example, within 10 minutes) Ozone released from ozone ice can be prevented from redissolving in the dissolved water of ozone ice.

  In the said invention (invention 1-4), it is preferable that the said ozone ice encloses the capsule with which 0.006-0.02g of said gelatinizer was enclosed with respect to 1g of said ozone ice ( Claim 6).

  According to the above invention (invention 6), since the amount of the gelling agent enclosed in the capsule is within the above range, all the dissolved water of the ozone ice can be gelled and released from the ozone ice. It is possible to effectively prevent the generated ozone from redissolving in the dissolved water of ozone ice.

  Moreover, this invention provides the ozone ice packaging body characterized by including the ozone ice which concerns on the said invention (Invention 1-6), and the bag body which accommodates the said ozone ice (Invention 7).

  According to the above invention (invention 7), the ozone ice stored in the bag body is dissolved, so that ozone can be released to the outside of the bag body, and the dissolved water of the ozone ice is put inside the bag body. Therefore, it is possible to prevent the dissolved water of ozone ice from leaking out of the bag body.

Hereinafter, an ozone ice package according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic perspective view showing an ozone ice package according to this embodiment, and FIG. 2 is a schematic perspective view showing ozone ice in this embodiment.

  As shown in FIGS. 1 and 2, the ozone ice package 1 includes a substantially cylindrical ozone ice 2, a capsule 3 enclosed in the ozone ice 2, and a bag 4 containing the ozone ice 2. Have.

  The ozone ice 2 is obtained by freezing water containing ozone (ozone water). In the present embodiment, the shape of the ozone ice 2 is a substantially cylindrical shape, but is not limited to this, for example, any shape such as a polyhedral shape including a cubic shape, a rectangular parallelepiped shape, and a spherical shape. Also good.

  The amount of ozone released from ozone ice 2 is relative to the amount of ozone required for sterilization, corrosion prevention and discoloration prevention of fresh foods, etc., so that the required amount of ozone is released by calculation in advance. It is necessary to contain ozone in the ozone ice 2. The amount of ozone contained in the ozone ice 2 is determined by the ozone concentration of the raw material ozone water.

  Generally, in order to maintain freshness of fresh food and the like and prevent corrosion, the ozone concentration of ozone water that is a raw material of ozone ice 2 is preferably 25 to 40 mg / L, particularly 30 to 40 mg / L. Preferably there is. If the ozone concentration of the ozone water is less than 25 mg / L, the amount of ozone contained in the ozone ice 2 decreases, and in order to maintain the freshness of fresh food, etc., a plurality of ozone ice packages 1 must be used. In addition, there is a risk that it may be costly to store fresh food and the like. In addition, when the ozone concentration of ozone water exceeds 40 mg / L, it is possible to maintain the freshness of fresh foods and prevent corrosion, but the amount of ozone released from the ozone ice 2 increases so that fresh foods. Etc. are not preferred because they may be discolored or bleached.

  The ozone ice 2 in this embodiment includes a plurality of capsules 3 enclosing a gelling agent. In the present embodiment, one ozone ice 2 contains capsules 3 in which eight gelling agents are enclosed. However, the number of capsules 3 in ozone ice 2 is limited to this. It is not a thing.

  The capsule 3 is made of a water-soluble material, and is preferably one that dissolves in water within 10 minutes after contact with water, and further dissolves in water within 6 minutes. It is preferable that it dissolves in water in about 2 to 3 minutes. If it dissolves for more than 10 minutes after coming into contact with water, the ozone released from the ozone ice 2 may be redissolved in the dissolved water of the ozone ice 2, and the ozone ice 2 There is also a risk that the dissolved water of the ozone leaks from the ozone ice package 1.

  Examples of the water-soluble material constituting the capsule 3 include cellulose resins such as hydroxypropylcellulose, hydroxypropylmethylcellulose, and hydroxypropylethylcellulose; gelatin resins; starch resins and the like.

  These water-soluble materials constituting the capsule 3 are preferable because they dissolve in the dissolved water within 10 minutes after coming into contact with the dissolved water of the ozone ice 2. Thus, when the dissolved water of the ozone ice 2 and the capsule 3 come into contact, the capsule 3 is dissolved, and the gelling agent enclosed in the capsule 3 and the dissolved water of the ozone ice 2 come into contact with each other. The dissolved water is gelled.

  Of these, hydroxypropylethylcellulose is preferred as the water-soluble material constituting the capsule 3. Hydroxypropyl cellulose is particularly preferable because of its good solubility in water.

  The film thickness of the capsule 3 is preferably 0.006 to 0.02 μm, particularly preferably 0.009 to 0.01 μm. When the film thickness of the capsule 3 is within the above range, the capsule 3 dissolves in the dissolved water within 10 minutes after the dissolved water of the ozone ice 2 comes into contact with the capsule 3, and the gelling agent and the dissolved water are separated. Since the dissolved water can be gelled by contact, the ozone released from the ozone ice 2 can be prevented from redissolving in the dissolved water, and the dissolved water of the ozone ice 2 can be removed from the bag body 4 (ozone. It is possible to prevent leakage to the outside of the ice package 1).

  Examples of the gelling agent encapsulated in the capsule 3 include a crosslinked sodium salt of an acrylic acid polymer, a cationic polymer flocculant, a urethane resin water-absorbing polymer, etc., but the ozone ice dissolves. There is no particular limitation as long as it can gel the dissolved water produced. Among these gelling agents, an acrylic acid polymer partially sodium cross-linked product is preferable because it is particularly excellent in the gelation ability of water.

  The amount of the gelling agent enclosed in the capsule 3 contained in the ozone ice 2 can be appropriately changed according to the type of the gelling agent. It is preferable that 006 to 0.02 g of the gelling agent is enclosed in the capsule 3, and in particular, 0.009 to 0.01 g of the gelling agent is preferably enclosed in the capsule 3. If the amount of the gelling agent is less than 0.006 g with respect to 1 g of ozone ice 2, the dissolved water of ozone ice 2 cannot be sufficiently gelled, and the dissolved water may leak out. When the amount of the gelling agent exceeds 0.02 g with respect to the ozone ice 2, the dissolved water of the ozone ice 2 becomes a granular solid substance, and the bag body 4 may be broken by the solid substance. Solid material may leak from the site.

  The bag body 4 is formed from a woven fabric or a non-woven fabric, and is capable of transmitting ozone gas released from the ozone ice 2 and does not transmit water. Examples of fibers constituting such a woven fabric or non-woven fabric include polyester fibers, acrylic fibers, polyethylene fibers, nylon fibers, rayon fibers, polypropylene fibers, polyvinyl chloride fibers, and the like. It may be used in a mixture of two or more.

  The bag body 4 is formed by folding a substantially rectangular or substantially square woven or non-woven fabric so that a pair of opposite sides overlap each other and opening three end edges (first sealing portion 4A and second sealing portion 4B). And the opening 4C). As a result, the ozone ice 2 is held in the bag 4.

  Examples of the sealing means for sealing the three end edges (the first sealing portion 4A, the second sealing portion 4B, and the opening portion 4C) of the bag body 4 include ultrasonic welding. According to the ultrasonic welding, it is possible to reliably seal the three end edges of the bag body 4 without causing cracks.

  When the three edges (the first sealing portion 4A, the second sealing portion 4B, and the opening portion 4C) of the bag body 4 are sealed by ultrasonic welding, the bag body 4 is made of polypropylene fiber. It is preferable that it is comprised with the nonwoven fabric. Since the bag 4 is made of a nonwoven fabric made of polypropylene fibers, it can be easily sealed by ultrasonic welding.

Woven or basis weight of the nonwoven fabric constituting the bag 4 is preferably 35~45g / ^{m 2,} it is preferred that particularly 40~45g / ^{m 2.} If the weight per unit area is less than 35 g / m ² , the water resistance of the bag body 4 may be low, and the dissolved water of the ozone ice 2 may leak out. If it exceeds 45 g / m ² , the air permeability will be low, and the ozone ice There is a possibility that ozone released from 2 cannot sufficiently pass through the bag body 4.

Moreover, it is preferable that the air permeability of the woven fabric or nonwoven fabric which comprises the bag body 4 is 40-50 mL / sec / cm < ² >, and it is especially preferable that it is 43-45 mL / sec / cm < ² >. If the air permeability of the bag body 4 is less than 40 mL / sec / cm ² , a sufficient amount of ozone may not be transmitted, and if it exceeds 50 mL / sec / cm ² , dissolved ozone ice water may leak out. There is.

Furthermore, the water pressure resistance of woven or non-woven fabric constituting the bag 4 is preferably 250MmH ₂ O or more, particularly 300mmH preferably at ₂ O or more, more preferably at 350MmH ₂ O or more. If the water pressure resistance of the bag body 4 is less than 250 mmH ₂ O, the dissolved water of ozone ice may leak out.

  The bag body 4 may have a configuration in which a plurality of woven fabrics or nonwoven fabrics as described above are stacked. By adopting such a configuration, the bag body 4 is formed so as to transmit ozone more and not transmit water more, and is formed with higher strength. Accordingly, the ozone ice package 1 is not preferably brought into contact with water such as fresh food such as sashimi because the dissolved water of the ozone ice 2 does not leak out of the ozone ice package 1. It can be suitably used for storage of things.

  In order to manufacture the ozone ice package 1 according to the present embodiment, first, two of the three open edges of the bag body 4 are sealed to seal the first sealing portion 4A and the second sealing portion 4A. The sealing portion 4B is formed, and the remaining one edge is formed as the opening 4C.

  Next, a predetermined concentration of ozone water is injected into the bag body 4 from the opening 4C of the bag body 4, and the capsule 3 in which a predetermined amount of gelling agent is sealed is introduced, and the opening 4C of the bag body 4 is opened. Seal.

  Subsequently, the ozone water is frozen while the bag body 4 contains the ozone water and the capsule 3. Thereby, the ozone ice packaging body 1 which accommodated the ozone ice 2 in which the capsule 3 was enclosed in the bag body 4 can be obtained. The time from injecting ozone water into the bag 4 to freezing the ozone water is preferably within 90 seconds. If the time until the ozone water is frozen exceeds 90 seconds, the capsule 3 may be dissolved before the ozone water is frozen, and the ozone water is dissolved in the ozone water before it is frozen. Ozone may vaporize.

  As shown in FIG. 3, the ozone ice package 1 according to this embodiment includes a box 10 having a hollow double structure and a lid 11 having a hollow double structure that closes an upper opening of the box 10. And the heat insulation container 13 provided with the hollow part of the box 10 and the heat insulation layer 12 inserted by the hollow part of the cover body 11 can be accommodated and used with the fresh food etc. as the contents 14. Thereby, the freshness of the fresh food etc. which are the contents 14 is maintained by the ozone discharge | released from the ozone ice 2, and corrosion is prevented. In the heat insulating container 13, the ozone ice package storage unit 11 </ b> A is formed on the inner surface of the lid 11, and the ozone ice package 1 can be stored in the ozone ice package storage unit 11 </ b> A. Since ozone has a higher specific gravity than air or the like, ozone released from the ozone ice 2 settles in the lower part of the heat insulating container 13. Since ozone diffuses inside the heat insulating container 13, the freshness of the fresh food as the contents 14 can be maintained.

  At this time, when the ozone ice 2 accommodated in the ozone ice package 1 is dissolved over time, the capsule 3 contained in the ozone ice 2 is dissolved by the dissolved water of the ozone ice 2, and the capsule 3 When the gelling agent and the dissolved water come into contact with each other, the dissolved water is gelled. Thereby, the dissolved water of the ozone ice 2 does not leak out of the ozone ice package 1, and the contents 14 can be prevented from being damaged by water adhering to fresh food or the like as the contents 14. .

  The embodiment described above is described for facilitating understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
