Furthermore, the element of the scrambled egg can ensure the safety against heat during cooking in the microwave oven by devising the position of the weak seal part that can become the steam hole of the packaging container and the cutting line for forming the discharge port. it can.

<Processed liquid egg>
The processed liquid egg of the present invention refers to a liquid egg mixed with a material that has a desired taste and flavor.
The liquid egg used in the present invention is not particularly limited. For example, liquid whole egg, liquid egg yolk and liquid egg white, and filtration, sterilization, freezing, drying, concentration, dilution, desugaring, desalting, enzyme treatment, etc. And those obtained by removing the specific components (cholesterol, lysozyme, avidin, etc.), and the like. The liquid egg may be thawed after freezing.
The liquid whole egg may be a raw whole egg obtained by splitting a chicken egg, or a chicken egg that has been split and liquid egg yolk and liquid egg white are separated and mixed in predetermined proportions.
For example, as long as the said processed liquid egg is normally edible besides liquid egg, as long as the effect of this invention is not prevented, any may be mix | blended. For example, meat, vegetables, dairy products, saccharides, edible fats and oils, starch, heterogeneous proteins, thickeners, pH adjusters, spices, seasonings, pigments and the like can be mentioned. The processed liquid egg in which these are blended may have a Western or Japanese flavor. For example, in the case of Japanese style, so-called fried egg-style scrambled eggs can be produced.

<Processed liquid egg: Ratio of liquid whole egg>
In the present invention, the ratio of the whole liquid egg when the processed whole egg is contained in the processed liquid egg is not particularly limited, and may be, for example, 50% or more and 90% or less, and more preferably 60% or more and 85% or less. .

<Hot-coagulated eggs>
The heat-coagulated egg of the present invention refers to one obtained by coagulating all or part of the processed liquid egg. The heat-coagulated egg of the present invention may be produced by boiling the processed liquid egg into an overheated state. Thereby, as will be described later, a heat-coagulated egg in which “su” is formed can be produced. Moreover, the heating nonuniformity may be formed in the heat-coagulated egg.

<Packing container>
The packaging container of the present invention refers to a packaging container for microwave cooking in which the processed liquid egg is enclosed.
The packaging container of the present invention is, for example, a soft plastic bag, which can squeeze a heat-coagulated egg in which a processed liquid egg is cooked by heating, heat resistance of 100 ° C. or higher, strength to withstand a predetermined pressure caused by internal steam. What is necessary is just to have a certain degree of flexibility. As a material for such a packaging container, for example, one or more plastic materials such as polyethylene, polypropylene, nylon, polyethylene terephthalate, ethylene-vinyl alcohol copolymer resin, and polyvinylidene chloride can be used.
The packaging container may have a configuration in which a plurality of soft plastic films are overlapped and the periphery is sealed, or a configuration in which one or a plurality of soft plastic films are bent in a palm shape and a joint portion is sealed.
The shape of the packaging container is not particularly limited, and may be, for example, a flat bag or a standing pouch type. Further, the packaging container may have a schematic shape such as a trapezoidal shape, a rectangular shape, a pencil shape having a combination of a trapezoidal shape and a rectangular shape, and an elliptical shape in plan view, and has other shapes. Also good.
In addition, planar view shall mean seeing from the direction perpendicular | vertical to the main surface of a packaging container in the state which has not enclosed the contents (processed liquid egg).
The packaging container has a storage portion, a weak seal portion, and a cutting line. Furthermore, the packaging container has a plurality of ends constituting the periphery. Hereinafter, each of these elements will be described.

<Packing container: end>
The edge part of a packaging container means the area | region which comprises the periphery of a packaging container which does not accommodate a processed liquid egg.
Of the end portions of the packaging container, the end portion on the side where the later-described weak seal portion is formed is defined as one end portion (also referred to as a first end portion), and the end portion paired with the one end portion is the other end portion (the first end portion). Also referred to as two ends). The other end portion (second end portion) is an end portion facing the first end portion with an accommodating portion described later interposed therebetween.
Moreover, the packaging container may have a pair of edge part which connects these 1st edge parts and 2nd edge parts, and these are made into a side edge part.
Each said edge part is comprised by the heat seal, the fold of a plastic film, etc., and the whole is sealed in the state before a heating.

<Packaging container: storage section>
The storage unit stores the processed liquid egg. The accommodating portion is a region surrounded by the respective end portions.
The accommodating part may be configured in a trapezoidal shape, a pencil shape, an elliptical shape or the like in plan view. Alternatively, the accommodating portion may have a substantially rectangular shape in plan view, for example, a shape in which a heat seal is indented into a part of the rectangle, a shape in which a portion that can be a discharge port described later protrudes from a part of the rectangle, or the like. You may have.
The capacity | capacitance of an accommodating part is not specifically limited, For example, the volume which can provide the scrambled egg for 1 person or more and can be accommodated in the store | warehouse | chamber of a normal microwave oven should just be mentioned, for example, 50-300 mL is mentioned.
Since the above-mentioned each end part is sealed in the state before heating, the container can prevent leakage of the processed liquid egg during distribution, storage, and handling by the cook. On the other hand, at the time of heating, the moisture contained in the processed liquid egg is heated to become steam, so that the pressure in the housing portion rises and swells. Along with this, all or part of the later-described weak seal portion is opened, and the vapor in the housing portion is released. Thereby, the bursting of the accommodating portion can be prevented.

<Packaging container: weak seal part>
A weak seal part is formed in the one end part (1st end part) of an accommodating part, and it is comprised so that it can open | release based on the raise of the pressure in an accommodating part. In other words, the weak seal part is fully or partly opened during heating by the microwave oven, and can function as a steam hole for releasing the steam generated in the storage part by heating to the outside of the storage part.
Specifically, the weak seal portion is one in which the heat fusion strength is adjusted to be weaker than that of the peripheral seal portion (simply referred to as a weak heat fusion region), or the width of the heat fusion region is adjusted to be narrower than that of the peripheral seal portion. (Simply referred to as a narrow heat fusion zone) and tapes having an easily peelable tape (simply referred to as an easily peelable tape). Further, the weak seal portion may have an opening, a small hole, a slit, a notch or the like for releasing steam.
In addition, a container adjusted to a shape in which stress is likely to concentrate on the weak seal part (simply referred to as “easy peeling heat fusion type”)
May be used.

<Packaging container: Pressure at which the weak seal is opened>
The weak seal portion is formed by releasing the heat-sealed area, the narrow heat-bonding area, the easily peelable tape or the like based on the increase in pressure in the housing portion, and opening the sealed area, or the above-described opening, small It is opened by opening holes, slits, notches and the like. The weak seal portion can be opened, for example, when the pressure in the housing portion is 5 kPa or more and 100 kPa or less under the condition of 25 ° C. With the weak seal portion having a certain level of pressure resistance, the processed liquid egg in the housing portion can be boiled to be in an overheated state, and a heated solidified egg in which “su” is formed can be produced.
“Su” is formed by the formation of fine bubbles by boiling the water in the processed liquid egg by overheating in the state where air bubbles enter the surface and inside of the heat-coagulated egg. Such “su” is a problem in smooth egg dishes such as chawanmushi and custard pudding because it impairs the texture and appearance.
On the other hand, scrambled eggs are usually cooked while being stirred, so by forming "su" and heating unevenness due to overheating, the surface becomes three-dimensional and a scrambled egg with a high handmade feeling can be produced. it can.

<Packaging container: cutting line>
A cutting line is formed in the periphery of the accommodating part which faced one end part (1st end part), and is comprised in order to form the discharge port of the heat-coagulated egg by which the processed liquid egg was cooked.
The cutting line is formed by, for example, a printed cut line, a perforated line, a notch for facilitating cutting, an easy cut line in a straight-cut film, or the like. When the cutting line is formed by a notch, the cutting line may be a virtual line formed by connecting a pair of opposed notches, or a virtual line extending in the direction in which the notch is formed. It may be a typical line. Moreover, although the easy cut line in a linear cut film may also be comprised as a virtual line, you may display the position of a line, the extending direction, etc. in the 1 or several location on the said line in a packaging container. Further, the notch may be used to indicate the position and the extending direction of the easy cut line.
The discharge port of the present invention is configured as an opening formed in the housing portion by cutting a part of the packaging container along a cutting line after cooking by a microwave oven.
One cutting line may be provided so as to form one discharge port, or one cutting line may be provided so as to form a plurality of discharge ports. Alternatively, the packaging container may have a plurality of cutting lines, and each cutting line may be provided to form one or a plurality of discharge ports.

<Packing container: width of discharge port>
Further, the cutting line is defined so that the width of the discharge port is 0.5 to 3 cm, and is further defined to be 1 to 2 cm. The width of the discharge port refers to the length of the accommodating portion along the cutting line.
The width of the discharge port can be realized by devising the shape of the accommodating portion and the position of the cutting line. For example, the width of the discharge port in the above range can be realized by forming one end of the accommodating portion narrower than the other end and forming a cutting line near the one end. Or the width | variety of the discharge port of the said range can be implement | achieved by providing 1 or several protrusion part which protrudes toward a 1st end part in an accommodating part, and forming a cutting line on the said protrusion part. In addition, the whole packaging container may be comprised by what is called a bottle shape by this protrusion part.

<Packaging container: Embodiment 1 (trapezoidal type)>
Hereinafter, specific embodiments of the packaging container will be described with reference to the drawings. In addition, the packaging container of this invention is not limited to these aspects.

All of the seal portions 13a, 13b, and 14 other than the weak seal portion 12 have a sufficient sealing property so as not to be peeled even when the pressure in the accommodating portion 11 is increased by heating.
The accommodating portion 11 is configured as a region surrounded by the weak seal portion 12, the side seal portions 13 a and 13 b, and the bottom seal portion 14. The accommodating portion 11 is configured such that the width along the first end portion 10a is narrower than the width along the second end portion 10b, and more specifically, from the second end portion 10b toward the first end portion 10a. The width is gradually reduced.
The cutting line 15 is formed substantially in the vicinity of the weak seal portion 12 of the first end portion 10a. Thereby, the cutting line 15 can be formed in the narrow area | region of the accommodating part 11, and the width | variety D of a discharge outlet can be prescribed | regulated to the said range. Furthermore, since it is comprised so that the width | variety of the accommodating part 11 may become narrow gradually, when squeezing out from a discharge outlet, a heat-coagulated egg can be collapsed also in an accommodating part. In the example shown in FIGS. 1 and 2, the cutting line 15 is configured as a printed cutting line.
In addition, the weak seal portion 12 is a weak heat fusion zone and is formed along the first end portion 10a. For this reason, when the pressure in the accommodating part 11 rises, the center part of the weak seal part 12 with a weak seal | sticker may open, and a steam hole may be formed.
Further, the weak seal portion 12 is formed on the front end side of the packaging container 10 with respect to the cutting line 15. For this reason, when a discharge port is formed by cutting along the cutting line 15 after cooking, the steam hole is also cut off. Therefore, when discharging the heat-coagulated egg from the discharge port, it is possible to suppress the risk that the steam hole itself or hot steam leaking from the steam hole touches the hand of the cook. Furthermore, it is possible to prevent a problem that the heated coagulated egg leaks from other than the discharge port.

The seal portions 23a, 23b, 24 other than the weak seal portion 22 have sufficient sealing properties so that they do not peel even when the pressure in the accommodating portion 21 rises, and the weak seal portion 22 has a narrow heat fusion zone. It is.
As shown in the figure, also in this case, the accommodating portion 21 is configured such that the width along the first end portion 20a is narrower than the width along the second end portion 20b. Moreover, the accommodating part 21 is comprised so that it may be substantially the same width | variety from the 2nd end part 20b to the intermediate part toward the 1st end part 20a, and a width | variety may become narrow gradually after the said intermediate part. Thereby, also in this embodiment, the width D of the discharge port is configured to be narrow by the accommodating portion 21 configured such that the width along the first end portion 20a is narrower than the width along the second end portion 20b. be able to.
About the structure of the cutting line 25 and the weak seal part 22, since it is the same as that of the cutting line 15 and the weak seal part 12 of the above-mentioned packaging container 10, description is abbreviate | omitted.

<Packaging container: Embodiment 3 (rectangular shape)>
FIG. 4 is a plan view showing a packaging container 30 according to still another embodiment of the present invention. The packaging container 30 is also configured as a so-called flat bag in which a plurality of soft plastic films are overlapped and the periphery is heat-sealed, and has a rectangular shape in plan view. Such a roughly shaped packaging container is hereinafter referred to as a “rectangular shape”.
The packaging container 30 includes an accommodating portion 31, three weak seal portions 32, and a cutting line 35. The packaging container 30 further includes a top seal portion 36 formed along the first end portion 30a, a pair of side seal portions 33a, 33b formed along the side end portions 30c, 30d, and a first end, respectively.

<Scrambled egg manufacturing method>
The method for producing a scrambled egg of the present invention is a method for producing a scrambled egg using the above-mentioned scrambled egg packed in a packaging container for microwave cooking.
That is, the step of forming a heat-coagulated egg in the housing part by heating the raw scrambled egg packed in the packaging container for microwave oven at least until the weak seal part is opened, and after heating It includes a step of forming the discharge port by cutting the packaging container along the cutting line, and a step of squeezing the heat-coagulated egg from the discharge port. This will be specifically described below.

<Manufacturing method of scrambled eggs: process of forming heat-coagulated eggs>
First, the scrambled egg is heated in a microwave oven. Although the attitude | position of the packaging container in a microwave oven is not specifically limited, It arrange | positions so that the weak seal part in which a steam hole is formed may face upwards or a side. Thereby, after opening a weak seal part, while steam is discharged | emitted smoothly, possibility that the part of the process liquid egg during heating will leak through a steam hole can be reduced. However, since most of the processed liquid eggs are usually solidified when the steam holes are opened, the processed liquid eggs can leak through the steam holes even if the posture of the packaging container is other than the above. The nature is considered low.
Heating is performed until at least the weak seal portion is opened. As a result, the processed liquid egg in the container is overheated and the processed liquid egg boils, so that a heated solidified egg containing “su” can be formed. Further, bumping may occur during heating.
The heating condition of the microwave oven is not particularly limited, and for example, the output may be 100 W to 2000 W, and the heating time may be about 30 seconds to 10 minutes.
Thereby, the solidified or semi-solid heat-coagulated egg can be formed in the accommodating part.

<Scrambled Egg Manufacturing Method: Step of Forming Discharge Port>
Subsequently, the packaging container after heating is cut along the cutting line. Cutting may be performed using scissors, a cutter, or the like, or may be performed manually. Thereby, one or a plurality of discharge ports having a width of 0.5 to 3 cm are formed.

<Method for producing scrambled eggs: step of squeezing heated coagulated eggs>
Finally, the heated coagulated egg is squeezed out from the discharge port. Specifically, for example, the heated coagulated egg can be discharged from a narrow discharge port by directing the discharge port downward and squeezing the entire packaging container.
Thereby, the heat-coagulated egg collapses naturally during the discharging process, and a scrambled egg with a higher handmade feeling can be produced.

<Operational effect of the present invention>
Since the base of the scrambled egg of the present invention is defined so that the width of the discharge port of the packaging container is 0.5 to 3 cm, the heat-coagulated egg produced in the accommodating portion is squeezed out from the narrow discharge port. Can do. Thereby, when taking out a heat-coagulated egg from the inside of a storage part, a heat-coagulated egg can be collapsed naturally and a scrambled egg with a high handmade feeling can be manufactured. As described above, according to the present invention, it is possible to eliminate the process of squeezing the packaging container, the process of crushing the heated coagulated egg taken out from the packaging container, and the like. A scrambled egg with a high handmade feel can be made easily.
Moreover, the packaging container of this invention has the structure by which a weak seal part is open | released and the steam hole is formed when the pressure in an accommodating part rises rather than the structure by which the steam hole is formed before a heating. Thereby, it is possible to overheat the processed liquid egg in the container to a boiling state, and so-called “su” can be formed. By squeezing the heat-coagulated egg on which “su” is formed from the discharge port, a scrambled egg having a three-dimensional shape can be produced, and the texture of hand cooking can be brought closer.
In addition, by using a microwave oven for heating, heating unevenness can be generated unlike a hot water bath or the like. Therefore, the heat-coagulated egg can be formed so as to have a rough texture, and a scrambled egg close to the texture of home cooking can be produced as compared with a heating method using hot water.
In addition, since the cutting line is formed at the peripheral edge of the housing portion facing the first end, the steam hole can be excised by forming the discharge port, or the discharge port and the steam hole are located close to each other. Can be arranged. Thereby, in the process of squeezing the heat-coagulated egg with the discharge port facing downward, it is possible to suppress the risk of hot steam being released to the hand or the like. Therefore, a scrambled egg can be manufactured safely.

  Hereinafter, the present invention will be further described based on examples and the like.

As shown in Table 2, in the packaging container of Comparative Example 4, the weak seal portion was formed at the center of the packaging container, and the cutting line was formed facing the first end. That is, in this packaging container, the joint portion of the plastic film is formed at the center of the packaging container, and this joint portion is configured as a weak seal portion. About the said packaging container, with reference to Table 2, the other was comprised similarly to the packaging container of Example 1. FIG.

[Examples 5 to 8]
Raw materials were uniformly mixed at the ratio of Formulation Example 1 listed in Table 1 to produce processed liquid eggs.
Subsequently, the produced processed liquid eggs were filled in trapezoidal packaging containers in the same manner as in Example 1. This produced the scrambled eggs of Examples 5-8.
The packaging containers of Examples 5 to 8 each had the same configuration as the packaging container of Example 1 except for the pressure resistance of the weak seal portion. That is, as shown in Table 2, the width of the discharge port was defined as 1.5 cm, and there was one weak seal portion. Moreover, the weak seal part was formed in the 1st edge part, and the cutting line was also formed facing the 1st edge part. Note that the pressure resistance of the weak seal portion can be adjusted by the adhesiveness of the weak seal portion.

[Test Example 1: Measurement of pressure at which a weak seal is opened]
The pressure at which the weakly sealed portions of Examples 1 to 8 and Comparative Examples 1 to 4 were opened was measured by an internal pressure strength test. The internal pressure strength test was performed as follows using a sealing strength / rupture strength tester (RHEO FKT-100-J, manufactured by San Kagaku Co., Ltd.).
First, under a condition of 25 ° C., a needle is inserted into a sealed empty packaging container and fixed so that there is no air leakage, and a pressure gauge and a compressor are connected thereto. Next, the compressor was operated, air was fed at a flow rate of 1 ± 0.2 L / min, and the maximum pressure when the weak seal portion was opened was read. The values are shown in Table 2 as “pressure resistance of the weak seal part (packaging container)” when the weak seal part in Examples 1 to 8 and Comparative Examples 1 to 4 was opened.

[Test Example 2: Evaluation of safety during production of scrambled eggs]
Subsequently, for each of the scrambled eggs of Examples 1 to 8 and Comparative Examples 1 to 4 where heated coagulated eggs were formed in the housing part until the weak seal part was opened, the packaging container was cut along the cutting line. And cut to form a discharge port.
As described above, when a heat-coagulated egg is formed in a microwave oven, it is in an overheated state. For this reason, depending on the position of the steam hole formed by opening the weak seal portion, the steam hole or the high-temperature touches the hand of the cooker and the like, and safety cannot be ensured. Furthermore, even when hot heated coagulated eggs are discharged from the steam holes instead of the discharge ports, there is a possibility that the heated coagulated eggs may touch the cooker's hand and the like, and safety cannot be ensured.
Therefore, the safety when squeezing the heated coagulated egg from the discharge port was evaluated as “safety during squeezing”, and the results are shown in Table 2. In Table 2, ◯ indicates that it is difficult to feel heat and can be squeezed safely, and x indicates heat and it cannot be squeezed safely.
As shown in Table 2, Examples 1 to 8 were all safe and hard to feel heat when squeezing out. Similarly, Comparative Examples 1 and 2 were safe. This is because in Examples 1, 2, 4 to 8 and Comparative Examples 1 and 2, the weak seal portion is arranged on the tip side of the cutting line, and the steam hole is cut out when squeezing out. This is thought to be due to the lack of contact with steam. In addition, there was no problem that the heat-coagulated egg was discharged from a place other than the discharge port. Similarly, in Example 3, the weak seal portion is arranged so that a vapor hole is formed in the vicinity of the discharge port, and it is designed not to touch the vapor or the vapor hole when squeezing out. Conceivable.
On the other hand, as shown in Table 2, Comparative Examples 3 and 4 would touch hot steam holes when squeezed out, and could not be squeezed out safely. This is because when squeezing out, the squeezing is generally performed with a portion far from the discharge port, and in Comparative Examples 3 and 4, steam holes are formed at the second end portion and the central portion that are likely to be touched during squeezing. It is believed that there is.

[Test Example 3: Evaluation of scrambled egg texture]
Finally, the texture of the scrambled eggs produced by squeezing the heat-coagulated eggs from the scrambled egg ingredients of Examples 1 to 8 and Comparative Examples 1 to 4 was evaluated whether it was close to that of home cooking, and the results are shown in Table 2. Described. In Table 2, ◎ indicates that it has almost the same texture as scrambled eggs for home cooking, ○ indicates that it has a slightly inferior texture to scrambled eggs for home cooking, and × indicates that It shows that it has a completely different texture from scrambled eggs.
As shown in Table 2, the scrambled eggs made from the raw scrambled eggs of Examples 1 to 4 had almost the same texture as the scrambled eggs for home cooking. This is because the heat-coagulated egg collapsed appropriately during squeezing, and the inside of the container became overheated, causing “sud” and uneven heating to occur on the surface of the heat-coagulated egg. This is thought to be due to the appearance of a three-dimensional effect.
In addition, when comparing scrambled eggs made from the raw scrambled eggs of Examples 5 to 8, Examples 6 to 8 had almost the same texture as scrambled eggs for home cooking, but about Example 5 was slightly It had an inferior texture. In Examples 6 to 8 in which the pressure resistance of the weak seal portion is 10 kPa or more, the inside of the housing portion was sufficiently overheated. However, in Example 5 in which the pressure resistance of the weak seal portion was 5 kPa, it was weak. This is probably because the seal part was opened quickly and the inside of the accommodating part was not sufficiently overheated.
On the other hand, the scrambled egg made from the raw scrambled egg of Comparative Example 1 had a small crushed body of the heat-coagulated egg and was not close to the texture of home cooking. This is presumably because the width of the discharge port was as narrow as 0.3 cm.
In addition, the scrambled eggs made from the raw scrambled eggs of Comparative Example 2 had large crushed eggs of heat-coagulated eggs, and did not become close to the texture of home cooking. This is thought to be because the width of the discharge port was too large at 3.5 cm.

[Discussion]
From the above results, the scrambled egg of the present invention has a discharge port width of 0.5 to 3 cm, so that the heated coagulated egg heated in the container is discharged while being crushed. Can do. Thereby, the scrambled egg close | similar to the texture of a home-cooked dish can be manufactured simply. In addition, the weak seal part with a certain level of pressure resistance functions as a vapor hole, so that the heat-coagulated eggs are caused to become scrambled and heated unevenly by heating the microwave oven to produce a scrambled egg with a higher handmade feel. be able to.
In addition, since the weak seal portion that can become a steam hole is formed in the vicinity of the cutting line that can form the discharge port, it is difficult to be affected by the heat of the steam hole itself or steam when squeezing, and other than the discharge hole It is possible to prevent a risk that the heat-coagulated egg is discharged from the vapor hole or the like. Therefore, it can cook safely.
