Abstract

PURPOSE:To obtain a separately packaged food which can be used as it is without opening the bag or in a state charged into other food, by sealing a part or total of a food in a bag made of an edible film. CONSTITUTION:A food such as seasonings for instant noodles or carry roux is charged into a bag made of an edible film (e.g. chitin film or soya protein film) produced from a composition composed of a polyhydric alcohol and a natural polysaccharide. The sealing part of the bag is applied with water and sealed with heat under pressure in the presence of water to obtain the objective food sealed in a bag of an edible film. The sealed food is further sealed in the same plastic bag, etc., singly or in combination with other foods.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a separately packaged food product in which different or similar food materials are separated from each other and sealed in the same bag until just before cooking or eating. .

The present invention can be used for various easily prepared foods that retain flavor by separately packaging and preserving foods that are added after dashi or condiments.

[Conventional technology]

Traditionally, for many ramen, miso soup, and other easily prepared foods, it is better to package them separately before pouring boiling water or simmering them, in order to preserve their flavor, even if they are ultimately eaten together. do. For example, when it comes to ramen noodles, there is a method that allows the seasoning ingredients to be absorbed into the noodle itself and then pours boiling water over it, but if you are looking for a more pleasant taste,
A preferred method is to store the seasoning ingredients in a small separate bag and add the seasoning ingredients from the separate bag after the noodles are swollen with boiling water.

For these reasons, there are various types of easily prepared foods on the market in which a part of the food is stored in a separate bag and the separate bag is opened before use.

[Problem to be solved by the invention]

However, in recent years, cooking, especially cooking at home, has become polarized between requests that require extreme effort and requests that require extremely less effort, and there is a tendency for people to be reluctant to even go through the trouble of tearing open a small separate bag in order to save time. There is.

Therefore, even if different types of foods are separated and packaged, they can be cooked as they are without having to open the separate bags before use.
There has been a need for a method of sealing food with an edible film that can be dissolved into a separate bag as a tasteless and odorless food material and can be eaten together with other foods without discomfort.

[Means of problem solving]

The present invention solves the above-mentioned problems, and its structure is to seal the food in a bag by heating and pressurizing an edible food film in the presence of moisture to produce an edible film-sealed food. On the other hand, it is characterized in that the edible film-sealed food is sealed alone or together with other foods in the same bag.

The edible film used in the present invention is a food product that is water resistant at room temperature, tasteless and odorless, and has sealability. As such a film-form food, Japanese Patent Application Laid-Open No. 62-1
Examples include a film manufactured from a composition of a polyhydric alcohol and a natural polysaccharide as disclosed in Japanese Patent No. 26940, a chitin film, a pullulan film, a soybean protein film, a surimi protein film, and the like. The edible film used as a packaging material is preferably tasteless and odorless, but in some cases, the edible film may be seasoned with a flavor that blends well with the overall food that will ultimately be eaten at the same time.

Polyhydric alcohols in a broad sense in the film produced from a composition of polyhydric alcohol and natural polyhydric alcohol include polyhydric alcohols in a narrow sense such as glycerin, and sugar alcohols, and in the case of liquids, they can be used as they are or in concentrated solutions. In the case of a solid, it is used as a concentrated solution, and a somewhat moist composition is obtained by kneading the polysaccharide and, if necessary, protein, its decomposition product, or amino acid. When this composition is dissolved in water to form a film, a film can be obtained which is insoluble in water at room temperature and dissolves in water when heated, depending on the conditions. Furthermore, depending on the conditions, an edible film that does not dissolve even in hot water can be obtained.

Natural data I! Examples include alginic acid, alginate sodium salt, alginate propylene glycol ester, agar, carrageenan, locust bean gum, guar gum,
Examples include tamarind seed polysaccharide, pectin, glucomannan, xanthan gum, pullulan, cyclodextrin, and chitin.

Proteins to be added as needed include soybean protein, egg white,
Examples include collagen, and polypeptides and amino acids that are the degradation products of these proteins are also used.

The characteristics of being water resistant at room temperature and soluble in hot water can be obtained by selecting the type of polysaccharide or the combination of polysaccharides, but in general, it is easier to obtain a water resistant film when protein is added. In the present invention, a water-resistant edible film is used.

The thickness of the edible film is not particularly limited, but is between 20 and 40 mm.
0μ, preferably 30-80μ.

The presence of moisture is important in sealing edible films. In the heat-sealing of ordinary plastic films, they are simply heated to melt them and then press-bonded to seal them, but with the edible film of the present invention, simply heating is not enough to cause the material to deteriorate. Since it is not sufficiently melted, it causes deterioration of the edible film and incomplete sealing, and also increases equipment costs. When heating and pressurizing is performed in the presence of moisture as in the present invention, complete sealing can be achieved at low temperatures without deteriorating the edible film.

In order to make moisture exist, it is possible to use a drying method as long as the moisture is supplied only to the area of the edible film that is to be sealed. For example, a sponge-like material may be soaked with moisture and then supplied to the sealing area, or a brush may be applied. There are methods such as applying it or spraying it.

For sealing, it is possible to easily form and fill edible film-sealed foods by using a regular automatic bag-forming and filling machine that has been modified to supply moisture to the area to be sealed. It will be done. This edible film-sealed food is hermetically packaged together with other foods, and when inserted into a heated aqueous solution or broth at a specified time without the need to open the bag, the bag will dissolve and will not separate and lose its flavor until this time. The retained internal seasonings are eluted and a deliciously seasoned food is obtained. Furthermore, if the contents are semi-fluid, they may be heated as they are.

The contents of edible film-sealed foods are often powdered seasonings, and can also be applied to various foods such as semi-liquid miso, powdered raw milk, and chocolate. In addition, the finished curry roux, hayashi roux, stew, etc. can be filled and sealed and stored frozen, and when used, the packaged bag can be heated to dissolve the bag and allow you to eat warm curry, etc. In this case, the flavor is also good because it is not a retort food unlike conventional foods.

In the case of edible films that do not dissolve even when heated,
If you seal cod roe and other fish roe, small fish, shaved cutlets, etc. and boil them as is, the stock will dissolve and the small foods will not disperse. Depending on the type of food packaged, the whole edible film bag can be eaten.

Since the packaging film itself is edible, it is necessary to further package it for distribution and preservation, and edible film-sealed foods with similar contents may be packaged together.
It is also used to separate and package different food materials so that the flavor does not deteriorate due to mutual mixing. Freezing is also possible for preservation.

[Effect]

The present invention involves selecting edible polysaccharide derivatives, polysaccharides, proteins, etc. that provide a flexible, heat-resistant film, and sealing the film by heating and pressurizing it in the presence of moisture to package food. It is something. Although it is not impossible to seal such an edible film by applying a high temperature of around 200° C., deterioration of the material and incomplete sealing tend to occur.

The inventors of the present invention have discovered that these edible films have the property of being easier to seal in the presence of moisture. By sealing some foods in this way and making them edible film-sealed foods, even if they are sealed at the same time as other foods, they will not be affected by other foods in the same way as if they were sealed in regular plastic film bags. It can be stored for long periods of time without being exposed to heat, and there is no need to open the bag before use; simply heat it or insert it into hot water, and the bag material will dissolve, allowing the contents to dissolve and create a unique flavor. It can be added. Alternatively, even if the bag material does not dissolve, it can be eaten as is.

[Example 1] 35 parts by weight of carrageenan, 25 parts by weight of glucomannan, 10 parts by weight of xanthan gum, and 5 parts by weight of collagen were kneaded, and 25 parts by weight of a 70% aqueous solution of sorbitol was added thereto and mixed well to form a slightly moist composition. I got something. 30 g of this composition was dissolved in 1β water and heated to 80° C. to form a film. The film was formed using a coater on an endless polyester belt moving at 0.5 m/min to a width of 60 mm and a thickness of 1 m.
Continuously coated to a thickness of 40 μm, then dried to a thickness of approximately 40 μm.
An edible film was obtained. When drying, the final moisture content is 12-15.
% to obtain an edible film. The average drying temperature was 85°C.

A water-containing sponge roller is provided to supply moisture to the vertical sealing part (3 mm from the sealing end) where the edible film thus obtained is sealed into a cylindrical shape.
After charging the contents into the resulting cylindrical body, a pillow-type automatic bag making and filling machine was used to simultaneously seal the seal at 3 cm intervals and cut the center of the sealed part using a pillow-type automatic bag making and filling machine equipped with a water-containing sponge for water supply to the horizontal sealer. Each bag was filled with 5 g of powdered soup stock and sealed to obtain a completely sealed 3 cm square edible film-sealed food product. The sealing temperature was 160°C.

This edible film-sealed food was sealed together with half-baked ramen noodles in an ordinary plastic bag to produce a product.

This product was stored completely separated from the half-baked ramen noodles even after one year without any leaching of the dried stock. In use,
Half-baked ramen noodles were boiled in boiling water, and when the edible film-sealed food was placed in a dish and boiling water was poured over the food, the edible film dissolved and the seasoning liquid inside leached out. By adding the boiled ramen noodles to the mixture and stirring, it was possible to cook delicious ramen noodles very easily.

[Example 2] The edible film used in Example 1 was applied to the same automatic bag-filling machine as in Example 1, and 2 g/bag of powdered milk with 10% or more milk fat was filled to produce an edible film-sealed food. Manufactured. The 10 bags of the edible film-sealed food were collectively filled into a plastic film bag. In use, when the edible film-sealed food containing milk was placed directly into a cup of coffee, the taste of the coffee was similar to that of using regular powdered milk. In addition, edible films may come into close contact with each other during storage and distribution, or milk may leak.
There was no decline in quality.

〔Effect of the invention〕

According to the present invention, it has become possible to separate food into one sealed bag and store it for a long period of time, and to use it without opening the bag (it can be used as it is in the food.Furthermore, the edible film-sealed food of the present invention It can also be stored frozen, and can safely withstand long-term storage even if the contents are somewhat perishable.
