Description

Description: TECHNICAL FIELD The present invention relates to a packaged food, and more specifically, to a solid food material and a semi-liquid food material that are heat-treated in a container with a partition layer made of an edible film. The present invention relates to a packaged food that is heated by a microwave oven or the like that is filled with vial and then used for eating.

Conventional Technology For example, cooked rice with curry roux such as curry rice is preferred because it is easy and delicious. For this reason, when curry rice is used as a packaged food, it is packaged with a curry roux aluminum foil or the like, and cooked rice is packaged with an olefinic synthetic resin or the like as a packaged food, which are sold separately or in combination. ing. However, with such a method, curry roux and cooked rice must be separately packaged in terms of production, and the work is complicated. In addition, those who purchase these packaged foods have to heat both curry roux and cooked rice, and it is not possible to heat them in a microwave oven at one time and to use them for edible foods, which means that cooking is time-consuming. There was a problem.

Also, if curry roux is directly put on the cooked rice in the packaging container, and this is subjected to an appropriate treatment such as sterilization to make a packaged food, it can be used just by heating it in a microwave oven or an oven. However, if it is stored for a long period of time, curry roux will seep into the cooked rice and the appearance will be poor, and the taste will also deteriorate, which is not practical.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention aims to solve the above problems, specifically, a packaged food by directly applying a semi-liquid food material for seasoning to a heat-treated solid food material, When this is stored for a long time, the semi-fluid food material for seasoning permeates into the solid food material, the taste deteriorates and the appearance deteriorates, and it is difficult to prevent this, and such problems The aim is to solve problems such as insufficient research to be done.

Means for solving the problem and the action thereof, that is, the present invention, from a solid food material heat-treated in the lower layer in the container, and a semi-liquid food material to season the food material in the upper layer In addition, a partition layer made of an edible film is provided between the lower solid food material and the upper semi-fluid food material.

Further, the means constituting the present invention and the operation thereof will be described below with reference to the drawings.

FIG. 1 is a sectional view of one embodiment of the packaged food according to the present invention.

Reference numeral 1 is a packaging container, 2 is a container body, 3 is a lid, 4 is a solid food material, 5 is a partition layer, and 6 is a semi-fluid food material.

First, the packaging container 1 of FIG. 1 is composed of a container body 2 and a lid 3. The lower layer of the container body 2 is filled with a solid food material 3 and the upper layer of the material is a fluid food material. A partition layer 5 made of an edible film is provided between these respective material layers.

Since the packaged food is heat-treated in a microwave oven or an oven and provided for edible use, a heat-resistant synthetic resin such as PET resin or vinylidene chloride resin is used as the material for the packaging container 1 of the packaged food. Is processed and molded into a container. The solid food material 4 is a solid food material that has been processed by heating or the like and can be immediately used for cooking if heated in a microwave oven or an oven.

Specific examples thereof include cooked rice, cooked rice such as stir-fried rice, boiled spaghetti, udon, ramen, and noodles such as oil-treated ones thereof. Further, these may be added with vegetables, meat and the like.

The semi-fluid food material 6 is preferably a semi-fluid food material such as a sauce, which has a certain high viscosity and does not pass through the partition layer 5. The reason for this is that a substance having a low viscosity easily permeates the partition layer. Further, the taste or the like needs to be able to be appropriately seasoned according to the type of the solid food material 4. The partition layer 5 is composed of an edible film and is provided so as to partition the solid food material 4 and the semi-fluid food material 6.

It is important that the partition layer 5 is such that the semi-fluid food material 6 does not soak into the solid food material 4 during long-term storage, and its thickness depends on the type of edible film, but is 30 to 5
It is sufficient that the thickness is about μm, and if it is less than 30 μm, the permeation preventing effect is small, and if it exceeds 50 μm, the effect does not change. It is preferable that the partition layer 5 has an edible film uniformly arranged on the entire upper surface of the solid food material 4, but if necessary, one of the solid or semi-fluid food materials is wound to form the partition layer 5. Does not matter.

Specific examples of the edible film used as the partition layer include wafer, amylose film, alginic acid film, bullan film, collagen film, gelatin film and the like. Among these, wafer and bullan film are particularly preferable.

The use of such an edible film as a partition layer is (1) that does not adversely affect the human body, (2) that the semi-liquid food material does not soak into the solid food material, (3) This is because the packaged food does not change the taste and does not form foreign substances.

The configuration and the action of the present invention have been described above. Next, an example of the method for producing the packaged food of the present invention will be described.

First, a container having a predetermined shape and size is prepared, for example, as shown in FIG. After filling the processed solid food material such as heating in this container,
A edible film having a predetermined thickness for forming a partition layer is laid on the entire surface of this material, and a semi-fluid food material is filled and sealed on the edible film. Then, about 60 ~ 80 ℃ in warm water
After heating for 30 minutes, the intended packaged food is obtained.

The thus-prepared packaged food has a real feeling, and when heated after being heated in a microwave oven or the like, a warm appetizing food is obtained, and the same taste as when cooked can be enjoyed.

In addition, it is an excellent packaged food that can be retained without being impregnated with the semi-liquid food material in the solid food material layer even after long-term storage.

Example Cooked rice cooked in oil was used as a solid food material 4 in a PET resin packaging container 1 having the structure shown in FIG. 1, and a 50 μm-thick wafer film was placed as a partition layer 5 on top of this. As a semi-liquid food material 6, white sauce containing shrimp was put therein, sealed with a lid 3 and kept in warm water at 80 ° C. for 0.5 hour to sterilize to obtain a packaged food.

When this packaged food was placed in a microwave oven and heat-treated, the sauce did not seep into the cooked rice and the sauce was put on the cooked rice, which was a good feeling.

Further, when this packaged food was stored for 6 months, no abnormality was observed and it was revealed that the effect of the partition layer was great.

<Effects of the Invention> As described above, the present invention comprises a heat-treated solid food material in the lower layer of a container and a semi-liquid food material for seasoning the food material in the upper layer. Moreover, a partition layer made of an edible film is provided between the lower solid food material and the upper semi-fluid food material.

Since the packaged food of the present invention is provided with a partition layer made of an edible film in a container so as to partition a solid food material and a semi-liquid food material, a semi-liquid food material in a solid food even after long-term storage It is retained without seeping. Further, for example, when heated in a microwave oven or the like, the sauce is put on warm cooked rice, which is suitable as a packaged food having a good appearance.
