Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum-packaged food product in which food products are vacuum-packaged in a close contact state.

[0002]

2. Description of the Related Art The vacuum-packaged food has been widely used not only for general households but also for restaurants because it enhances the storability of cooked foods and has the convenience that it can be set immediately by opening it. In the conventional vacuum packaging, cooked foods were packed in a bag while being in close contact with each other, deaerated, and heat-treated.

[0003]

The food items that are vacuum-packaged in close contact with each other are vacuum-packaged, and when they are secondarily heated in a vacuum state for sterilization, they are bonded to each other to form a lump, which can be separated individually when opened. It will be difficult. Especially for thin slices, the effect is strong, and the thin slices that overlap each other stick to each other as shown in FIG. , In the meat-wrapped burdock using the sliced meat, the adhered part of the sliced meat around the burdock peels off and a hole is formed. Therefore, vacuum-packaged foods are unsightly and can be recognized at a glance, which is also a cause of lowering the evaluation.

[0004]

In view of the above-mentioned drawbacks of the prior art, the present invention ensures separability and enables the original shape to be maintained. The fine powder of silicon dioxide is sprinkled on the separating surface of about 0.25% by weight of the food and integrally packaged in vacuum.

[0005]

[Function] Since the fine powder of silicon dioxide is present at the boundary between the foods that are in close contact with each other, the foods can be easily separated even if they are heat-treated.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A vacuum packaged food product according to the present invention will be described with reference to the drawings. No. 1 is a sliced beef topping which is a topping material for beef bowl, and this sliced meat is cooked by a sauce. As shown in FIG. 1a, 0.25% by weight of fine powder of silicon dioxide 2 was sprinkled on the surface of the thin sliced meat, which was packed in a bag 3 and vacuum packed. (B of FIG. 1), secondary heating is performed also for sterilization.

[0007] In this state, not only the storage stability is improved, but also by simply heating and opening the bag when necessary, the same state as the fresh one can be reproduced. Fine powder of silicon dioxide is sprinkled on the adhered surface of the sliced meat, so even if the sliced meat is secondarily heated in a vacuum state, the sliced meat does not bond to each other and has excellent separability. It can be done (Fig. 2). The reason is not clear, but it is presumed that the fine powder of silicon dioxide functions as an insoluble water retention film, and as a result of the test, regarding the separability between before vacuum packaging and after secondary heating after vacuum packaging. Almost no difference was observed. Since the sliced meat can be separated individually even after opening,
When serving in a beef bowl, it can be placed neatly on rice with other toppings, such as onions and shirataki.

Silicon dioxide is tasteless, odorless and nontoxic,
It is also chemically stable and does not deteriorate or decompose in food. Its use as a food additive has also been approved by the Ministry of Health and Welfare, except for breast milk substitutes and weaned foods (Gazette No. 4 / January 17, 1991), and its safety has been established. The fine powder of silicon dioxide used in the examples is
It is porous with a particle size of 2 microns or less, and it does not feel uncomfortable when mixed, and it is possible not only to disperse it on the surface but also to inject it inside to disperse it.

In order to facilitate understanding of the present invention, the above-mentioned embodiments take thin sliced meat as an example, and in particular, in the drawings, a primitive powder is prepared by sprinkling finely divided powder of silicon dioxide in a container held by hand on each sliced meat. However, for foods other than thinly sliced meat, as long as they are vacuum-packaged in close contact with each other, the effect of maintaining separability is demonstrated, and of course, with an automated device in a large factory. It is premised on mass production. In addition, the principle of the present invention is, for example, a hamburger,
If it is applied to foods such as meat dumplings that are kept in a sloppy state and bonded to each other, and also to hams, sauces, breads, confectionery and the like, a new texture can be expected to be created.

The fine particles of silicon dioxide have a particle size of 2 microns or less, and the ideal amount of 0.25% by weight of the food is the average value. For some foods, it is preferable to increase or decrease a little, and the particle size and the amount to be sprayed can be understood as a guide only.

[0011]

EFFECTS OF THE INVENTION According to the present invention, foods vacuum-packed in close contact with each other do not bond to each other even when heated, and the shape before packing is maintained as it is even after opening, effectively reducing quality. It can be prevented.
