Description

  The present invention relates to a raw chicken egg packaging method and packaging container, and more particularly, to a packaging method for flavoring a raw chicken egg with a fruit scent while maintaining the freshness of the raw chicken egg, and the packaging container.

In the conventional technology, techniques for suppressing the decline in freshness of raw chicken eggs include carbon dioxide treatment of eggs wrapped in a vinyl chloride egg pack, covering eggs with a storage cover, injecting carbon dioxide, and placing eggs in a container. There are a method of filling and covering with a polyester-based synthetic fiber sheet, and a method of packing chicken eggs in a container, covering with a polyester-based synthetic fiber sheet, and sealing (for example, see Non-Patent Document 1). In addition, after storing raw chicken eggs in an egg packaging container that includes an egg storage unit that stores eggs and a quality maintenance agent storage unit that stores a quality maintenance agent that generates a gas that maintains the quality of the eggs, this chicken egg There is a method of sealing the peripheral surface of the packaging container with a heat seal (for example, see Patent Document 1). All of these are techniques for suppressing the decrease in the how-unit value and maintaining the freshness of the raw chicken eggs by suppressing the carbon dioxide gas inside the raw chicken eggs from leaking outside the chicken eggs.
Tadao Nakagawa, 3 others, “Suppression of freshness reduction of eggs using carbon dioxide”, [online], March 1989, Journal of public testing research institute, Niigata Agricultural Research Institute Livestock Research Center, Niigata Livestock Test Site Research Report No. 8, p19-24, [Search May 6, 2003], Internet <http://rms2.agsearch.agropedia.affrc.go.jp/contents/JASI/pdf/PREF/43-0965 .pdf> Japanese Utility Model Publication No. 2-15410

  In the technique of Non-Patent Document 1, a large amount of raw chicken eggs collected on the farm are treated with carbon dioxide gas at a time, and there is a problem that the equipment becomes large and the construction cost and maintenance cost of the equipment increase. In addition, when displaying eggs at stores, such as storefronts, chicken eggs are stored in packaging containers packed with commercially available vinyl chloride egg packs that have air permeability. There is a problem that the holding effect is lowered. On the other hand, in order to solve these problems, in the technique of Patent Document 1 described above, after the quality maintenance agent and raw chicken eggs are stored in the egg packaging container, the peripheral surface of the egg packaging container is sealed with a heat seal. This peripheral surface needs to be completely sealed, and it is also necessary for the consumer to be able to open the egg easily with a finger or the like, but the strength of sealing and the ease of opening are contradictory. Therefore, high-level technology is required for sealing by this heat seal. In addition, if there is no room between the stored raw chicken egg and the peripheral surface of the packaging container (the part to be heat sealed), the heat sealing device will contact the egg through the packaging container in the process of heat sealing, There is a risk that the container and eggs will break. For this reason, the heat sealing operation | work of a packaging container requires the very high technique of processing only to the peripheral surface of a packaging container. Therefore, there are problems such as an increase in equipment costs associated with higher performance of the heat seal device and an increase in expenses for training skilled workers. In any of the above-mentioned documents, since the raw chicken egg is not flavored such as a fruit scent, the smell unique to the raw chicken egg may suppress the appetite of consumers.

  The present invention has been made in view of the above-mentioned problems of the prior art, and contains raw chicken eggs in a commercially available egg-containing container having air permeability, along with fruit flavors for food and carbon dioxide. By using a bag making device and hermetically wrapping with a packaging material made of an airtight material, the scent of fruit is added to the raw chicken egg to increase appetite and maintain the freshness of the raw chicken egg. A simple packaging method and a packaging container for the same are provided.

  For this reason, the present invention accommodates raw chicken eggs in a breathable chicken egg storage container, and the egg storage container in which the raw chicken eggs are stored is formed of an airtight material together with a fruit flavor and carbon dioxide. The first feature is that the packaging material is hermetically packaged.

  Moreover, the packaging method of the raw chicken egg of Claim 1 WHEREIN: It is the 2nd characteristic that a packaging material is a three-sided seal bag.

  A third feature is that the air-permeable egg storage container containing the raw chicken eggs is hermetically packaged with a packaging material formed of an airtight material together with a fruit flavor and carbon dioxide.

  Furthermore, the packaging container for raw chicken eggs according to claim 3, wherein the packaging material is a three-sided seal bag.

  According to the packaging method and packaging container for raw chicken eggs according to the present invention, the raw chicken eggs are stored in a commercially available egg storage container having air permeability, and a commercially available bag making apparatus is used together with a fruit flavor for food and carbon dioxide gas. A simple packaging method for maintaining the freshness of raw chicken eggs while improving the appetite by flavoring the raw chicken eggs with the scent of fruit by sealing and wrapping with a packaging material formed of an airtight material. And the packaging container can be provided.

  Hereinafter, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings. The raw egg packaging method of the present invention is a method in which a raw egg is contained in a breathable egg-containing container molded from a commercially available substantially transparent material, and the egg-containing container is marketed together with a fruit flavor for food and carbon dioxide. This is a method of hermetically packaging with a bag making apparatus. Further, in this embodiment, as described later, the raw chicken eggs are contained as silica gel, which is known as a desiccant for maintaining the quality of food, as a mold prevention means that is one means of maintaining quality. Sealed and packaged with the egg storage container, fruit flavor and carbon dioxide.

  FIG. 1 is a perspective view of a raw chicken egg packaging container according to the present invention. As shown in FIG. 1, the raw egg packaging container 1 has a fruit flavor 3 and an antifungal agent 4 placed on an egg containing container 2 containing chicken eggs 7, and carbon dioxide gas 5 is enclosed. The packaging material is hermetically wrapped in a three-side seal bag 6.

  FIG. 2 is an explanatory diagram of the egg container 2, the fruit flavor 3, and the antifungal agent 4. As shown in FIG. 2, the egg storage container 2 is a commercially available egg storage container formed of polyethylene terephthalate (PET). In this embodiment, six eggs in three lines in the longitudinal direction and two lines in the short direction. It is composed of an array. The egg storage container 2 is composed of an upper lid portion 2a and a lower housing main body portion 2b formed in substantially the same shape as the lid portion 2a. Six recesses 2d are formed. The lid portion 2a having a substantially rectangular plane is formed with a lid recess 2c formed following the outer shape of the egg 7, and a separating portion 2e is provided in the adjacent lid recess 2c. One edge portion in the longitudinal direction of the lid portion 2a is crimped to the edge portion of the lower accommodating main body portion 2b to form a hinge portion 2f. The housing main body 2b is formed with a housing recess 2d formed following the outer shape of the chicken egg 7 in the same manner as the lid 2a, and the adjacent housing recess 2d is provided with a separating portion 2e. A vent hole 2g is perforated in the upper part of the lid recess 2c, so that the egg storage container 2 is air permeable. In the present embodiment, the raw chicken egg container 2 containing 6 pieces is described as the best embodiment, but is not limited to the container containing 6 pieces, for example, containing 8 pieces or 10 pieces. The effects of the present invention are the same even in the egg storage container.

  The eggs 7 are housed one by one in the housing recess 2d of the housing body 2b with the lid 2a opened, and then the lid 2a is rotated around the hinge 2f as a support shaft to thereby move the housing 2b. All the accommodated eggs 7 are covered with the lid recess 2a. At this time, the adjacent chicken eggs 7 are prevented from coming into contact with each other and breaking by the separating portions 2e provided on the housing main body 2b and the lid 2a. The peripheral portions other than the hinge portion 2f of the housing main body 2b and the lid portion 2a are crimped to such an extent that they can be easily opened with a finger or the like. This crimping method can be replaced by fastening with a stapler or sticking with an adhesive tape. Examples of the material for the egg container 2 include substantially transparent materials such as polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC) in addition to polyethylene terephthalate (PET). It is not limited to.

  The fruit fragrance 3 is obtained by impregnating a commercially available flavor 3a having a scent of citrus fruit with a paper 3b harmless to food. The flavor 3a is sealed in a three-sided seal bag 6 as shown in FIG. After packaging, it volatilizes gradually, and after a certain period of time, it is flavored by the eggs 7 accommodated in the egg-containing container 2 having air permeability. This flavor 3a is a commercially available food fragrance, and various fragrances are generally prepared by blending a natural fragrance or a synthetic fragrance. In this embodiment, a citrus fruit fragrance was used, but the fragrance may be other than citrus fruit. The flavor 3a uses a liquid fragrance having volatility, but may be a solid fragrance having sublimation.

  Moreover, the fungicide 4 is a commercially available desiccant, and the silica gel 4a on the grain is packaged with a material having air permeability. Indispensable factors for mold growth are mold fungus, temperature, humidity and oxygen. If at least one of these factors can be removed or controlled under certain conditions, mold growth Is suppressed. Therefore, the removal or control of these four factors will be examined.

  First, it is difficult to reliably remove or sterilize bacteria such as mold fungi even after washing the eggs. In this embodiment, it is assumed that mold bacteria adhere to the raw chicken eggs, Consider mold means. Next, in order to control the temperature, a large-scale temperature control facility is required, which is expensive and cannot be easily realized. As for the humidity management, controlling and adjusting the humidity to a constant humidity requires a large humidity control facility similar to the temperature control, which is expensive, and cannot be easily realized. However, it is known that silica gel is used as a desiccant for food, and its drying effect is also known. By using such a desiccant, mold growth can be suppressed. In this example, silica gel was used as a fungicide as a commercially available desiccant, but quicklime or activated carbon can be substituted. Furthermore, as will be described later, by sealing the carbon dioxide gas 5 in the three-sided seal bag 6, the oxygen concentration in the three-sided seal bag 6 is reduced, and the antifungal effect is enhanced.

  FIG. 3 is an explanatory view of a method for packaging raw chicken eggs according to the present invention. As shown in FIG. 3, the egg storage container 2 storing the raw chicken egg 7 is hermetically packaged together with the fruit flavor 3 and the fungicide 4 by a commercially available three-side seal bag making apparatus 8. In this three-side seal bag making apparatus 8, a product to be packaged (in this embodiment, a chicken egg storage container 2 in which a raw chicken egg 7 is stored, a fruit fragrance 3, a fungicide 4) is K-coated OPP and PE laminated. Carbon dioxide gas 5 is sealed while being sealed and packaged with a three-side seal bag 6 formed of a film. Therefore, the oxygen concentration in the sealed three-sided seal bag 6 is greatly reduced compared to the concentration in the atmosphere, and mold growth can be prevented. K coat is an abbreviation for polyvinylidene chloride coating, OPP is an abbreviation for stretched polypropylene, and PE is an abbreviation for polyethylene. The laminated film is also generally called a laminated film.

  This commercially available three-side seal bag making apparatus 8 is an apparatus that can easily seal and package confectionery or the like together with carbon dioxide gas or nitrogen gas in a three-side seal bag. In addition to the K-coated OPP and PE laminated film as described above, the material of the three-side sealed bag 6 of the packaging material is, for example, a K-coated ON (stretched nylon) and PE laminated film or K-coated. Although there is a substantially transparent material having airtightness (gas barrier property) such as a laminated film of PET (polyethylene terephthalate) and PE, it is not particularly limited to this, and a substantially transparent material having airtightness (gas barrier property) suitable for foods. If it is good. By such a method, the raw chicken egg packaging container according to the present invention is formed.

  In this packaging method, the commercially available egg storage container 2 in which the raw egg 7 is accommodated is sealed and packaged by the commercially available three-side seal bag making apparatus 8 without using a special apparatus. The chicken eggs 7 can be easily sealed and packaged without damaging them, and the carbon dioxide gas 5 can be easily enclosed during the sealed packaging. Moreover, since the three-sided seal bag 6 is substantially transparent, the visibility when the consumer looks at the eggs 7 in the packaging container 1 displayed at the egg counter is also good. In addition, as described with reference to FIG. 2, the egg-containing container 2 is made air-permeable by punching a vent hole 2 g in the upper part of the lid 2 a of the egg-containing container 2, so that it is sealed in the three-sided seal bag 6. The oxygen concentration in the egg storage container 2 can be reduced by the carbon dioxide gas 5, the freshness of the raw chicken egg 7 can be maintained, and the effect of preventing mold can be increased as described above.

  Moreover, the fruit flavor 3 hermetically sealed in the three-sided seal bag 6 together with the egg container 2 volatilizes gradually, and the fruit scent permeates the raw egg 7 sufficiently through the vent 2g of the egg container 2. By scented, the effect of promoting the appetite of consumers is enhanced. In this embodiment, the fruit flavor 3 and the antifungal agent 4 are placed on the upper side of the egg storage container 2, but the effect is the same when placed on the lower side of the egg storage container 2. . Moreover, although carbon dioxide gas was used as the best mode for keeping the freshness of mold and raw chicken eggs, nitrogen gas can be substituted.

It is a perspective view of the packaging container of the raw chicken egg which concerns on this invention. It is explanatory drawing of a chicken egg storage container, fruit fragrance | flavor, and a fungicide. It is explanatory drawing of the packaging method of the raw chicken egg which concerns on this invention.
