Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging material for microwave cooking that covers at least a portion of food when it is cooked in a microwave oven.

[Prior art]

Microwave ovens have become widely used in ordinary households, and can heat food in a short time, allowing hot dishes to be served on the dining table.

Furthermore, in order to create brown marks even in a microwave oven, this was achieved by providing a heating element having a metal vapor deposited layer on a part of the container, as seen in Japanese Patent Publication No. 15548/1983.

[Problem to be solved]

Even if the heating element shown in the above-mentioned Japanese Patent Publication No. 15548/1988 is used, it is difficult to brown foods with a high moisture content, such as rice cakes, and the rice cakes are soft and eatable before browning occurs. state,
It has become impossible to heat it any further.

An object of the present invention is to provide a packaging material for microwave oven cooking that can be brought into direct contact with food and impart burnt marks and a burnt flavor to the food when the food is cooked.

[Means for solving problems]

The problem is solved by kneading either a burnt coloring or a flavoring into an edible film that can transmit microwaves, and covering at least a portion of the food with a material that forms a cooking layer on the surface of the other material and heating it in a microwave oven. did.

[Effect]

Even if the food contains a lot of water, when the food is heated in a microwave oven and the food is cooked, the coloring agent and flavoring agent provided on the edible film migrate with the edible film, creating a burnt atmosphere.

[Implementation row]

Examples of the present invention will be described below.

FIG. 1 is a cross-sectional view showing one embodiment of the cooking packaging material of the present invention, in which numeral 1 is an edible film such as pullulan, and a burnt flavor is kneaded into the edible film. This is a packaging material for microwave cooking, in which a dark brown coloring layer 2 of a desired shape is provided on the surface of the edible film 1.

Further, as shown in FIG. 2, this is a packaging material for microwave cooking in which a dark flavor layer 3 is provided on the surface of an edible film 1 kneaded with a dark brown colorant.

Here, it goes without saying that the dark coloring layer 2 may not simply be provided on the entire surface, but may be provided partially in a mesh or pattern.

Furthermore, in the above description, the edible film 1 includes:
Although it is a single film, for example, Figures 3 and 4
As shown in the figure, an edible film 1 in which either a dark brown coloring agent or a dark flavoring agent is kneaded is provided on a heat-resistant film 4 such as a polyethylene terephthalate film, and the other coloring layer is placed on the edible film 1. 2 or a laminated structure provided with a fragrance layer 3.

and when or after heating the food in the microwave with at least a portion of the food covered;
The heat-resistant film 4 may be peeled off.

[Effects] Since the present invention has the above-described structure, adhesion to foods with a high moisture content can be achieved by the adhesiveness of the edible film due to moisture, and the edible film can be used as it is to cook foods in a microwave oven. Not only can the food be cooked by heating it for a short amount of time, but it also gives a burnt appearance to foods with a high water content in the microwave, which makes them less appetizing.

In addition, in the case of rice cakes, it is possible to provide a coloring layer that suits the food, such as a mesh-like coloring layer.
It can be a non-conventional product.

Furthermore, if a heat-absorbing film is used as the heat-resistant film 4, it is possible to impart a burnt feel to an irregularly shaped food such as sweet corn on the cob.
