Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to microwave foods that can be heated in a microwave oven and served directly on the table.

<Prior Art> Retort food, which can be eaten simply by heating it in boiling water, has been known as an alternative to instant food. Retort food is packed in a retort pouch, and curry, stew, etc. are the mainstream. However, there is a problem with retort food in that it requires time and effort to boil water in a pot.

For this reason, microwave foods, which can be eaten simply by heating them in a microwave oven, are gaining popularity as easier foods. Such microwave foods are mainly
It is packaged in a plastic tray and can be heated in the microwave after opening.

<Problems to be Solved by the Invention> Microwavable foods are more convenient than retort foods because they can be eaten as is by simply heating them in a microwave oven, but they are generally more expensive than retort foods. However, conventional microwave foods are generally foods such as curry rice, spaghetti, and gratin, and are not very different from retort foods, so there is a desire for the emergence of new microwave foods that are not available in retort foods. .

In view of these circumstances, an object of the present invention is to provide a novel food for microwave ovens that has never existed before.

Means for Solving the Problems〉 The microwaveable food according to the present invention that achieves the above object has the following features:
A special feature is a container that can be heated in a microwave oven and has a certain shape, and that contains a whole potato or a block of potatoes of at least 50c+IU and a seasoning.

In the present invention, a container that can be heated in a microwave oven and has a certain shape is one that has heat resistance to heating in a microwave oven, has at least a part of it that is transparent to microwaves, and has a certain shape inside. A container that is strong enough to hold potatoes of a predetermined size and protect them from external forces to some extent.

Examples of containers that satisfy these conditions include C16.
Cans (manufactured by Central Stake Can Co., Ltd. [USA]) can be mentioned.

A C16 can has a main body made of a multilayered sheet of ethylene vinyl alcohol copolymer resin or polypropylene resin, and an aluminum lid wrapped around the opening.

In addition, a whole potato or a block of potatoes with a size of at least 50cI1 refers to a potato as it is, or a potato that has been cut, shaved, or cut off so that it can be placed in a container, and the potato has the skin attached. You can use it raw or with the skin removed, depending on the dish you're cooking. Furthermore, potatoes need to be cooked so that they can be eaten as they are, but they may be filled into a container after being cooked, or they may be filled raw into a container and then cooked. You can.

In the present invention, seasoning refers to something that imparts flavor to potatoes, and may be in liquid, solid, powder, or any combination thereof, and may be used in various types of sauces, sauces, meat, vegetables, etc. Examples include stewed ingredients.

The microwaveable food of the present invention is a whole potato or a block of potatoes having a size of at least 500111' and a seasoning sealed in the above-mentioned container, and is preferably heated and sterilized after being sealed so that it can be stored for a long period of time. It is better to

Effect> Since the microwave food of the present invention uses a container that can be heated in a microwave oven, it can be served as is by heating in a microwave oven, and the container has a certain shape. This allows the whole potato to be protected from external forces and does not need to be transferred to another container (it can be eaten as is.
Since it can be eaten by heating it in the microwave as a whole potato or a block of potatoes that are at least 50e1' in size, it is an unprecedented food that makes the most of the flavor of the potato material. . Furthermore, since a container with a fixed shape is used, filling of whole potatoes can be mechanized during production.

Incidentally, if you try to pack whole potatoes or blocks of potatoes that are at least 50cm in size into pouches, it will be difficult to fill them mechanically, and the whole potatoes will easily fall apart during transportation of the product. The flavor of the ingredients cannot be fully utilized.

Example of implementation Hereinafter, the present invention will be explained based on examples.

FIG. 1 shows a cross section of a microwave food according to one embodiment. As shown in the figure, there are two whole potatoes in container 1.
and 3 seasonings such as patter sauce and minced meat are included.

In this example, Yongil! The above-mentioned C10 can is used as No. 1. The container 1 has a lid IL made of aluminum wrapped around the opening of a resin container body 1a made of a multilayer sheet, and has a tubular shape with a diameter of 89 mm, a height of 63 mm, and a volume of 230 d. On the outer periphery of the container body 1a, there is a shrink film 4 made of a foamed resin having an anti-static function.
Moreover, an outer M5 made of polyethylene is provided on the upper part of the container body 1a so as to cover the lid 1b.

Note that a hole 5a for breathing is formed in the outer M5.

Figure 2: How to eat microwaveable food that burns! As shown in al., first remove the outer cover 5, then remove the aluminum cover 1.
Take b. Next, as shown in FIG. 2 (bl, (C)), cover the outer lid 5 again and heat it for about 90 seconds in a 500 W microwave oven.
You can eat it as is with a spoon or similar. Of course, you may transfer it to another container and eat it.

Next, an example of manufacturing the microwaveable food according to the present example described above will be briefly described.

First, adjust the seasoning 3 and boil the peeled potatoes 2. The size of this potato 3 is preferably 100 to 150 (!Im') in relation to the size of the container 1 described above.Then, the seasoning 3 and the potato 2 are placed in the container body 1a
After filling, the lid 1b is attached and sealed by seaming.

Thereafter, it is sterilized at 120° C. for 30 minutes, and a shrink film 4 and an outer lid 5 are attached to make it a microwaveable food.

Here, the potatoes 2 may be encapsulated in cooked form as described above, or may be encapsulated raw and then cooked during heat sterilization.

This eliminates the need to pre-cook the potatoes, and
It is possible to prevent collapse during filling.

By the way, when other foods are sealed in a C5C can and sterilized, it is generally necessary to heat the can at 120° C. for about 60 minutes.

However, in the microwave food of the present invention, the heat sterilization conditions can be shortened to about 30 minutes at 120° C. as described above. This is because at least highly heat-resistant bacteria do not live in the center of a whole potato.

General heat sterilization conditions are 120% all the way to the center of the container.
℃, but in the microwave food of the present invention, the center of the container is the center of a whole potato, and for the reasons mentioned above, the center of the potato is not necessarily heat sterilized at 120℃. Since it is not necessary and a temperature of about 100° C. is sufficient, the time for heat sterilization can be significantly shortened as described above.

Therefore, there is no loss of flavor due to long-term heat sterilization.
You can fully utilize the flavor of the ingredients.

Furthermore, if a C10 can is used and heat sterilized as in the above-mentioned example, it can be stored for more than one year at room temperature, and has excellent long-term storage stability compared to the six months of retort pouches.

<Effects of the Invention> As explained above, the microwave food according to the present invention can be heated in a microwave oven and is housed in a container having a certain shape, so it can be easily served on the table. You can eat it with a spoon.

In addition, the potatoes are contained whole or in large blocks, and the fixed shape of the container prevents them from collapsing, and the heat sterilization time can be shortened, allowing the umami of the potatoes to be utilized as they are, which increases the product value. It has a high value. In addition, since a container with a fixed shape is used, it is possible to mechanically fill whole potatoes, which reduces manufacturing costs and allows for longer storage compared to pouch packaging.
