Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw unwrapped raw material which allows fresh eggs to be circulated for a long period of time in a state where they are put out from a shell and sealed in a container that can be observed from the outside. The present invention relates to an egg and a sterilized packaging method thereof.

[0002]

2. Description of the Related Art Conventionally, raw eggs are packed in plastic packs or pulp slurry molding packs with shells, and are distributed while protecting the shells from cracking. However, since these containers do not have rigidity, there is a problem in that they must be handled with care during transportation. Also, since it is not possible to observe the contents from the outside with the shell,
There are problems that consumers cannot find a bad egg until they break the egg, or that the raw egg is stored for a few days and the storage period is short. In order to solve these problems, there has been proposed an egg in a packaging container in which the shell is removed from the egg and only the contents are contained in a plastic container and hermetically sealed (for example, JP 2001-301860 A, JP 1 A). -199809, JP-A-63-185353.
Issue).

[0003] The above-mentioned proposed raw eggs without shells are hermetically sealed without providing a head space, air in the head space is replaced with an inert gas and hermetically sealed, or a container is evacuated or a container is doubled. By vacuuming and sealing the outer space, oxygen in the container is removed and the shelf life of the egg is increased.

[0004]

By the way, in the case of raw eggs with shells, the carbon dioxide gas contained in the eggs at the time of spawning is released from the stomata of the eggshell with the passage of time, and the pH value of the egg white rises. As a result, it is known that the concentrated albumen decreases, the watery egg white increases instead, and the antibacterial activity of lysozyme contained in the egg white decreases. Therefore, the freshness of the raw egg can be known by observing the swelling state of the egg white. From that point of view, conventionally, a Hau unit value (hereinafter referred to as HU value) calculated from the weight of an egg and the height of a concentrated egg white is generally known as an index showing the freshness of an egg.

On the contrary, if the HU value can be kept high, the freshness of the egg can be kept.
Therefore, if the raw egg is distributed from the shell in the state of being packaged in a container, the freshness of the raw egg should be maintained as long as it has the effect of suppressing the reduction of the HU value as compared with the case of distributing the raw egg with the shell. It is possible to increase the commercial value of eggs. However, the conventional container-less shell-wrapped eggs described above,
All of them were made from the viewpoint of enabling long-term storage by removing oxygen in the container and ensuring a barrier property against oxygen in the container, and preventing oxidative deterioration of raw eggs. The one based on the technical idea of the effect of suppressing the decrease in the HU value of raw eggs has not yet been proposed. Therefore, the conventional container-less shell-wrapped eggs have not been able to satisfactorily exert the effects of maintaining the raised state of raw egg white in a fresh state and suppressing the decrease in antibacterial activity of lysozyme.

[0006] Therefore, the present invention is intended to solve the above-mentioned problems in the conventional shell-free packed eggs in a container, and maintains a high HU value by maintaining a fresh swelling state of raw egg white. An object of the present invention is to provide a container-free packaged egg and a method for aseptic packaging the same, which is capable of maintaining the effect of suppressing the decrease in antibacterial activity of lysozyme for a long time.

[0007]

Means for Solving the Problems In the study for obtaining a container-less shell-packaged egg having an effect of suppressing the decrease of the HU value for solving the above-mentioned problems, the present inventors have found that the HU value of a raw egg with a shell is decreased. Focusing on the relationship with the amount of carbon dioxide released, the following methods were used to determine the change in the number of days and the HU value of raw eggs with shells, and in that case the change in the number of days and the amount of residual carbon dioxide of raw eggs with shells. I investigated the relationship. At that time, carbon dioxide gas is substituted in the bag formed of the aluminum foil laminated film so that all raw eggs with shells can be started under the same conditions, and the eggs with shell are sealed and stored for one week. By doing so, the carbon dioxide substitution rate in all eggs was kept constant. After that, the temperature is 22 ℃ and the humidity is 6
Stored in 0% atmosphere, immediately after storage, 1 day, 3 days, 7
The HU value after 14 days was actually measured. HU value is H
(M) and W (g) were actually measured and determined by the following simple formula. HU value = 100 × log (H-1.7W ^0.37 +7.6) (1) However, H (m): concentrated egg white height W (g) 2 cm away from the yolk in the longitudinal direction: Egg weight The results are shown in diagram a in FIG. As shown in the figure, the HU value was 77.2 at the start of the actual measurement, but it decreased in an inverse function according to the number of days elapsed, and the freshness sharply decreased particularly by the 7th day of elapsed time. I know that

Next, assuming that the cause of the decrease in HU value, that is, the decrease in freshness, is correlated with the amount of carbon dioxide gas released from raw eggs,
The relationship between the number of days elapsed and the amount of carbon dioxide gas released in the egg was examined. Carbon dioxide emission of raw eggs with shells can be determined by measuring the residual carbon dioxide amount of raw eggs with shells, but it is difficult to directly measure the residual carbon dioxide amount of raw eggs with shells. Therefore, the initial pH value at the start of measurement was measured by the following method, and the initial carbon dioxide gas amount was estimated from the measured value of pH 7.00.

The relationship between the pH in the egg and the concentration of bicarbonate ion and carbonate ion when the carbon dioxide environmental concentration is changed is Brooks and
Pace et al. (Reference: Proc. Royal. Soc. London, Ser. B126
196-210, 1938), but from this relationship, the amount of ionized carbon dioxide gas in the egg and its hydrogen ion counter were calculated based on the test egg data shown in Table 1. As shown in FIG. 5, a graph was drawn, and the initial carbon dioxide gas amount of the test egg of 1.17 cc / piece was obtained from the results.

[0010]

[Table 1]

Next, Nakagawa et al.'S data on changes in pH of eggs with shells of raw eggs with shells (Reference: Poultry Friend No.332, P36-40, 1989, Egg Science and Technolog)
y, WJ Stadelman, 1955), and the amount of residual carbon dioxide gas at each time point was calculated from the pH values after 1 day, 3 days, 7 days, and 14 days by the same method as above. The result is shown in the diagram a in FIG.

As shown in the diagram a of FIG. 4, it was confirmed that the change curve of the amount of residual carbon dioxide gas with respect to the number of days elapsed has a tendency similar to that of the How unit with respect to the number of days elapsed. From this fact, there is a close relationship between the freshness of raw eggs and the amount of carbon dioxide released, and even if raw eggs are taken out of the shell, the release of carbon dioxide from the egg white is released at least as eggs with shells. Less than the amount (ie, Figure 4
In the graph shown in (1), if the control can be performed so that the change curve of the number of days elapsed-residual carbon dioxide amount is above the line a in the case of raw eggs with shells), the eggs are stored fresher than those with shell eggs. It turns out that it is possible.

By the way, the shell of raw eggs is 9 to 29 μ
m pores are present, and pores 0.5 to 1 μm inside the pores.
It has a structure in which there are two layers of eggshell membranes having m,
Carbon dioxide gas and moisture are released through these pores and pores according to the concentration of carbon dioxide gas outside. Therefore, unlike the case of the plastic container, the carbon dioxide gas permeation mechanism cannot be directly calculated, and therefore the condition of the plastic container satisfying the requirement corresponding to the raw egg shell cannot be directly obtained from the above result. Therefore, the inventors of the present invention prototyped raw egg filling containers using various materials, and experimentally determined a raw egg filling container having the same relationship as the relationship between the elapsed days of the raw eggs and the amount of residual carbon dioxide gas. As a result, it was discovered that, under the conditions described below, the case of a container made of polypropylene having a thickness of 150 μm has almost the same relationship as that of a raw egg, as shown in the diagram b in FIG. . The carbon dioxide permeability of polypropylene is 8 with a partial pressure difference of 1 atm.
Since it is 500 ml / 25 μm · m ² · 24 hr, the unit carbon dioxide permeation amount of this container is 1417 ml / m ² · 24 hr.
(Partial pressure difference was 1 atm). Therefore, if the unit carbon dioxide gas permeation amount is less than the unit carbon dioxide gas permeation amount, a container satisfying the above problems can be obtained.

The present invention has been made based on the above findings, and the unshelled raw egg of the present invention comprises a container body composed of a housing portion for housing raw eggs in a shellless state, and an opening portion of the container body. A shellless raw egg that is hermetically packaged in a raw egg shellless packaging container that includes a lid material that covers the container body and / or the lid material that is formed of a transparent synthetic resin material. The amount is 1 in terms of the gas partial pressure difference between the high pressure side and the low pressure side of 1 atm.
It is characterized in that it is formed so as to have a flow rate of 417 ml / m ² · 24 hr or less.

In order to satisfy the condition of the carbon dioxide permeation amount,
Carbon dioxide permeability of the container body and / or the lid material is 8500
It is desirable to be composed of a synthetic resin material smaller than ml / m ² · 24 hr · atm / 25 μm. The material of the container main body and / or the lid member is not particularly limited as long as it satisfies such conditions, but for example, polyester resin such as PET, polyamide resin such as nylon, ethylene vinyl alcohol copolymer, etc. The polyvinyl alcohol-based resin, vinyl chloride-based resin, vinylidene chloride-based resin, fluorine-based resin or the like may be used as a single layer or a composite material composed of a plurality of combinations. The packaging form is also not particularly limited, but it is desirable that the container main body is filled with raw eggs taken out of the shell one by one and the state thereof can be individually observed from the outside. A transparent or translucent material The plurality of housing portions are integrally formed by being connected to the housing portions that are adjacent to each other at a part of the lid material sealing portion, and can be separated into individual sealed housing portions by cutting at the connecting portion. Is desirable. Then, the packaging is a sterilized filled unshelled raw egg in which the unshelled raw eggs are filled and sealed in a sterile atmosphere, and / or carbon dioxide gas is supplied to the accommodating portion of the container body when filling the unshelled raw eggs. By substituting carbon dioxide gas for the headspace gas and packaging, a higher-quality raw shellless raw egg can be obtained.

The sterilized packaging method for unwrapped raw eggs according to the present invention for obtaining unwrapped raw eggs comprises a shell egg washing and sterilizing step for washing and sterilizing the outer peripheral surface of the raw eggs in a shell state. Container body washing and sterilization process to wash and sterilize the inner and outer peripheral surfaces of the container body, which consists of a storage unit that stores eggs in a shell-free state and a lid material sealing unit, and the washed and sterilized raw eggs are divided and washed in a sterile atmosphere Characterized in that it comprises a raw egg shell-free sterilization filling step of filling the container portion of the sterilized container body, and a sealing step of sealing the container portion of the container body filled with the shellless raw egg with a lid material. Is. The raw egg sterilization filling step is performed in a carbon dioxide gas aseptic atmosphere of a predetermined concentration as necessary, and the air in the container body is replaced with carbon dioxide gas at a predetermined replacement rate and then packed. The carbon dioxide gas substitution rate is preferably in the range of 10 to 88%.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a raw unwrapped raw egg according to an embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2 show a shellless raw egg pack according to an embodiment of the present invention, FIG. 1 is a perspective view thereof, and FIG. 2 is a sectional view taken along line AA of FIG. In the shellless raw egg pack 1, a unit pack 5 is composed of a container body 2 and a lid member 3. In the illustrated embodiment, the container body 2 is formed by connecting 6 unit packs 5 each capable of accommodating one egg. Has been done. Each of the unit packs 5 has a storage portion 6 formed of a cylindrical portion having a hemispherical lower portion and an open upper portion so that it can be stored as it is in an egg container of a household refrigerator.
It is composed of a lid seal flange 7 formed on the outer peripheral surface of the opening, and adjacent unit packs 5 are connected to each other in the vicinity of the tangent of the flange to form a communication part 8, which is integrally molded through the connection part. Has been done. On the other hand, in the lid material 3, the lid material film is heat-sealed to the lid material sealing flange 7 and the communication portion 8 in a sealing step described later,
The portion protruding from the outside is cut and removed at the same time as the heat-sealing step or in the post-step, and as shown in the figure, the opening is opened to cover the unit pack and communicate with each other via the communication section 8. In addition,
In the figure, 9 represents the egg yolk and 10 represents the egg white. Further, the lid material may be a molded lid.

The material of the container body 2 and the lid member 3 can hold the unshelled raw eggs hermetically sealed in the container so that the carbon dioxide gas retention is less decreased than that of the raw eggs with shells. It must satisfy the conditions and be transparent so that the state of the raw egg stored inside can be observed from the outside. In the present invention, the unit carbon dioxide gas permeation amount of the container in which the raw egg is filled and sealed is such that the partial pressure difference between the high pressure side and the low pressure side is 1a.
The container was constructed so that it was 1417 ml / m ² · 24 hr or less in terms of tm. Unit carbon dioxide permeation amount is 141
When it is 7 ml / m ² · 24 hr or more, the carbon dioxide barrier property is inferior to that of the raw egg shell and the HU value suppressing effect cannot be obtained more than that of the raw egg with shell, so less than that, preferably 140 ml
/ M ² · 24hr or less. And as a material that satisfies the condition, carbon dioxide permeability is 8500 ml / m ² · 24 hr
Below, a transparent or semi-transparent material whose inside can be seen through was selected.

As materials satisfying the above conditions, PET,
A single-layer or multi-layer material containing polyvinyl chloride, ethylene vinyl alcohol copolymer, etc. can be adopted. The container body is injection molded from these materials, and the lid material is made of a film made of these materials.However, the container body and the lid material are not necessarily the same material, and a combination of different materials may be used. It is desirable that the sealing surface between the material and the container body is made of a material that easily heat-seals.

The above-mentioned unshelled packaging pack is more microbially safe as compared with raw eggs with shells, because it is sterilized when it is sterilized during filling and packaging, and the subsequent invasion of bacteria is prevented. Low temperature distribution enables long-term distribution of fresh eggs. In the production of the sterilized packaging pack, first, the outer surface of the shell is washed and the shell is sterilized while the raw egg is in the shell state. On the other hand, the inner peripheral surface and the outer peripheral surface of the container body are sterilized in the container body cleaning and sterilizing step, and the lid material is sterilized in the lid material sterilizing step. Then, by splitting the washed and sterilized raw eggs in a sterile atmosphere, filling the accommodation portion of the washed and sterilized container body, and then replacing the air in the headspace with sterilized carbon dioxide gas and heat-sealing the lid material. The container of the container body filled with the shellless raw eggs is sealed to obtain the shellless aseptized packed raw eggs. Each of those steps is performed in a sterilization booth in which atmospheric air is cleaned, but by devising so as to prevent the flow of air between the booths in each step, for example, a shelled egg washing and sterilization step, By preventing the air in the booth where the container body washing and sterilization process and the lid material sterilization process are performed from flowing into the booth where the filling process and the sealing process are performed, the shellless aseptized packaged raw eggs with higher sterilization Can be obtained.

EXAMPLE In order to confirm the operation and effect of the present invention, a container main body composed of only a unit container for filling one egg whose bottom part is a dome-shaped container main body is made of PET, and an aluminum foil laminate is used as a lid material. I made several. The dimensions of the container body and the lid material are as follows. Container: Opening mouth diameter 4.33 cm Bottom dome radius 2.0 cm Height 5.5 cm Container volume 70.3 cm ³ Surface area (whole) 87.4 cm ² Surface area (lid) 14.7 cm ² Surface area (Body) 72.7 cm ² Body thickness 0.15 mm Eggs having an egg weight of 60 g and a volume of 52.2 cm ³ were filled and sealed in the above-mentioned container in a shellless state. The raw eggs to be filled in each container should be sealed in a bag made of aluminum foil laminated film substituted with carbon dioxide gas as described above so that the initial amount of carbon dioxide gas contained in each container is the same for each egg. Then 1
The one stored for a week was used. An aluminum foil laminated film was used as the lid material. Therefore, in this case, it is considered that there is no permeation of carbon dioxide gas from the lid member, and that carbon dioxide gas is exclusively permeated from the container body.

The unshelled raw eggs obtained as described above are stored indoors at a storage temperature of 25 ° C., and immediately after packaging, after 1 day, 3
After the lapse of days, after 7 days and after 14 days, the HU value was measured by taking out from the container. Further, as a comparative example, except that the container main body is made of PP, a container manufactured so that each of the above dimensions is exactly the same as the above example is filled with the same raw shellless eggs as the above conditions and sealed to form a raw shellless package. Eggs were produced, HU values were measured in the same manner every predetermined number of days, and changes in the how units were examined over time. The results are shown in FIG. 3 together with the above-mentioned eggs with shells. In FIG. 3, diagram c is PE
As shown in the figure, there is almost no change with time in the Hau unit, and a slight decrease is observed even after 14 days, which is clear from the case of raw eggs with shells. It can be seen that the freshness is excellent.
On the other hand, in the case of the container formed of PP of Comparative Example
(Line b) shows less change over time than eggs with shells,
The U value reduction suppression effect was small.

Next, the change with time of the residual carbon dioxide amount of the raw eggs contained in these containers was examined. The amount of residual carbon dioxide gas gradually decreases by permeation of carbon dioxide gas from the inside of the container to the outside until the concentration of carbon dioxide gas in the container is balanced with the concentration of carbon dioxide gas in the atmosphere. Since it is affected by the partial pressure difference of carbon dioxide,
In the experiment, the time-dependent change in the amount of carbon dioxide remaining in the container was examined by computer simulation based on the following calculation formula. In the case of a plastic container, the sequential carbon dioxide gas concentration in the container can be expressed by the following equation. CA (n + 1) = CA (n) + ΔQ / V (n) (2) where CA (n + 1): carbon dioxide concentration after a certain time CA (n): carbon dioxide concentration at a certain time ΔQ: carbon dioxide at a certain time Gas permeation amount V (n): Headspace volume at a certain time Further, the carbon dioxide gas permeation amount of the container can be expressed by the following equation. ΔQ = R × Sq × (Aco ₂ −Pco ₂ ) (3) Here, R: carbon dioxide permeability Sq: container permeation area Aco ₂ : atmospheric carbon dioxide partial pressure Pco ₂ : carbon dioxide content in the container at a certain time Pressure

Therefore, the amount of carbon dioxide gas in the container was calculated by calculating the concentration of carbon dioxide gas in the container every certain fixed time (12 hours in this experiment), and successively adding the amount of carbon dioxide gas permeated within that time. . The result is shown in FIG. As a result, in the case of the comparative example in which the material is PP, the changes in the residual carbon dioxide amount with respect to the number of days elapsed are substantially the same as shown in the figure. In this case, the unit carbon dioxide permeation amount of the comparative example can be calculated by the following formula. Unit carbon dioxide permeation amount = PP permeation × 25 μ / PP thickness of this experiment = 1417 ml / m ² · 24 hr (partial pressure difference 1 atm) Therefore, it is considered that the comparative examples are almost the same as the case of raw eggs with shells. By doing so, it is understood that the unit carbon dioxide permeation amount may be less than that on the basis of the unit carbon dioxide permeation amount. In the case of the comparative example in which the container body is made of PET, the unit carbon dioxide permeation rate is 57 ml / m ² ·
It was 24 hr (partial pressure difference 1 atm). And in this case,
As shown in the figure, the decrease in the amount of residual carbon dioxide with respect to the number of days elapsed was slight. Also, as shown in the diagram (c) of FIG. 3, the temporal change of the Hau unit was almost less than that of the eggs with shells, and it was confirmed that there was a particular effect in maintaining freshness. In addition, in the case of the example and the comparative example, the how unit is increased and a part is observed with the lapse of time, but it is presumed that the reason is as follows. In the case of raw eggs, there is a change in weight due to water permeation from the shell, and the measurement is based on the weight of each case. However, in the case of the example and the comparative example, there is no change in weight due to the absence of water permeation, so it is presumed that this was caused by an error due to calculation with the weight of the raw raw eggs with shells.

Although the embodiments and examples of the present invention have been described above, the present invention is not limited to the above examples, and various design changes can be made within the scope of the technical idea thereof. For example, in the above-described embodiment, only one raw egg is filled in the storage portion of the container main body, but the number of pieces to be filled in each storage portion is arbitrary, and the size of the storage portion can be selected according to it. it can. Further, the material and the wall thickness thereof are not particularly limited as long as the unit carbon dioxide permeation amount satisfies the above conditions.

[0026]

As described above, according to the present invention, a raw egg is filled and sealed in a transparent or translucent container having a unit carbon dioxide gas permeability lower than that of an egg shell in a shellless state. The product's freshness can be maintained over a long period of time to enhance its commercial value, and the white or yellowish state of raw eggs can be directly discriminated from the outside, so consumers should check their freshness and purchase with confidence. You can Further, the above-mentioned packaging makes it possible to maintain the pH value in a neutral region where lysozyme, which is contained in a large amount in the egg white, exhibits the strongest antibacterial activity, and it is possible to suppress a decrease in antibacterial activity of lysozyme. . Furthermore, the sterilized packaging is safer because it is less likely to be contaminated with bacteria than the eggs with shells. further,
Since it is a container and packaging, it is easy to handle at the distribution stage. Further, since there is no shell, there is no need to break the shell during cooking, the contents can be easily taken out, and the waste of the shell is not generated each time, which is a special effect.
