Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaged potato that can be made edible in a short period of time by heating it in a microwave oven while packaging the raw potato.

[0002]

2. Description of the Related Art Sweet potatoes are washed with water, wrapped in plastic wrap, heated in a microwave oven and edible into steamed potatoes, and then eaten as steamed potatoes, or removed and wrapped in an oven to remove the surface. Baking and eating is a common practice.

[0003]

If this sweet potato is left as it is, it may be gradually deteriorated and lose its taste, and buds may emerge and become unedible. In addition, when heating this sweet potato in a microwave oven, it is troublesome to wrap it in a wrap, and the wrap often traps steam in the wrap, making it watery, and often causes the wrap to swell and burst due to heating. I do. An object of the present invention is to solve the above problem and preserve the quality without deteriorating as much as possible, and when edible by a microwave oven, it is possible to safely heat it in a microwave oven just before packaging. It is intended to provide a packaged potato that can be eaten without being watery.

[0004]

In order to achieve this object, a first object of the present invention is to provide a backing made of a hygroscopic material in a wrapping material having air permeability and microwave permeability. A packaged potato characterized by containing a potato.

[0005] A second aspect of the present invention is the packaging potato according to the first aspect, wherein the packaging material is a non-breathable plastic bag having small holes formed in required portions.

A third aspect of the present invention is the packaging potato according to the first aspect, wherein the mount made of the hygroscopic material is cardboard.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, potatoes to be stored in a packaging material are mainly sweet potatoes, but potatoes can also be applied. As a packaging material used for packaging this potato, if it is a material that has air permeability and is permeable to microwaves when placed in a microwave oven,
There is no special limitation on the material, and various forms such as bags and boxes can be used.Especially, a non-breathable bag made of a plastic film with multiple holes formed to maintain breathability However, they are preferable in terms of low cost and mass productivity.

[0008] As the mount made of a hygroscopic material coexisting with the potato in the packaging material, any one that can appropriately absorb the moisture generated from the potato during storage and heating of the potato at room temperature is used. For example, there is no particular limitation on the material, and it is desirable to use cardboard or the like because it has an appropriate hygroscopic property and can be used at low cost.

[0009]

The packaged potato of the present invention is packaged in a packaging material having air permeability and microwave permeability together with a mount made of a hygroscopic material. Can be diffused to the outside due to the air permeability of the packaging material, and can be appropriately absorbed by the moisture absorption of the coexisting backing paper and stored as a potato having appropriate moisture.

However, in order to make this potato edible,
What is necessary is just to heat the packaged one in a microwave oven, and only the inner potatoes are quickly heated,
Excess water generated during the heating process is radiated to the outside from the air-permeable packaging material as water vapor, and at the same time, the backing made of a hygroscopic material coexisting inside absorbs the water to create a delicious potato that is full of water. it can.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below more specifically with reference to the accompanying drawings. FIG. 1 is a perspective view showing the packaged potato of the present invention with a part thereof cut away. The packaged potato 1 is made of a single sweet potato 2 washed with water to make the surface clean and free of water. Are housed in a square plastic bag 4 of a predetermined size made of a polyethylene film together with a mount 3 made of a hygroscopic material.

The plastic bag 4 is originally air-impermeable, but has air-permeability by forming a plurality of small holes 5, 5... The mount 3 to be stored together with the potato 2 in the plastic bag 4 has a rectangular shape on which the potato 2 can be placed, and both sides are bent to one side so that the movement of the potato inside is suppressed as much as possible. This holds the shape of a square bag.

[0013] Even if the packaged potato 1 is stored at room temperature as it is, the water coming out of the internal potato 2 is radiated to the outside through the small holes 5 formed in the plastic bag 4. At the same time, the moisture absorption of the backing sheet 3 allows it to be appropriately absorbed to prevent deterioration of the potato 2 and to store the bag 4 without swelling.

When eating the potato 2 in the packaged potato 1, the packaged potato 1 is heated in a microwave oven for a predetermined time without being opened, so that microwaves from the microwave oven are directly applied to the potato 2 The temperature can easily spread from the inside and spread within a short period of time to edible.

At this time, since the plastic bag 4 and the inner mount 3 do not absorb the microwave, there is no temperature rise due to the microwave, and substantially only the potato 2 is heated. By this heating, water vapor comes out of the potato 2 and fills the bag to inflate the bag 4, but the water vapor escapes from the small holes 5, 5,... Since the water vapor is appropriately absorbed, the bag 4 is not ruptured, so that the potato 2 can be edible by being heated plumply without being watery.

[0016]

According to the present invention, the packaged potato of the present invention can be wrapped in a microwave oven in comparison with a conventional method of heating a potato in a microwave oven, or by wrapping the potatoes tightly in a wrap. In addition to the convenience of being able to heat, only the inner potato can be quickly heated,
Excess moisture generated during the heating process is radiated to the outside from the gas permeable packaging material as water vapor, and at the same time, the backing made of the hygroscopic material coexisted inside absorbs the moisture and cannot be compared with the conventional heating. It can be a delicious and sweet potato.

Further, by wrapping the potatoes in the above-mentioned packaging material, the moisture of the potatoes can be appropriately blown off by the base material made of the air-permeable and hygroscopic material of the packaging material to extend the storage period. It has the advantage that it can be done.
Since the packaged potato of the present invention has a very simple packaging form using the above-described breathable packaging material and a mount made of a hygroscopic material, it can be manufactured inexpensively and mass-produced. It is excellent.
