[0011]

EXAMPLES The present invention will be described in more detail below by showing examples of the present invention. FIG. 1 is a cross-sectional view showing an example of this edible cold storage agent.

As shown in FIG. 1, this edible cold storage agent 1
Is configured such that the sealed container 2 is filled with the contents. The form of the sealed container 1 may be appropriately determined according to need, and examples thereof include a bag, a molded container, and a can.
More specifically, examples thereof include a plastic bag, a resin molded product, a metal can, and a composite bag made of a composite material such as resin and non-woven fabric. Among these, the plastic bag and the composite bag are preferable, and as the forming material thereof, various kinds of materials usually used for packaging materials can be used. Specifically, polyethylene film, polyolefin film such as polypropylene film, polyester film, polyvinyl acetate film, acid-modified polyethylene film such as ethylene-acrylic acid copolymer film, nylon film, polyvinyl chloride film, Chlorine-containing films such as vinylidene chloride film,
Polystyrene film, polycarbonate film, metal aluminum (Al) foil, metal vapor deposition film,
Examples include film laminated paper. These may be used alone or in combination of two or more.

For example, the shape of the bag made of these forming materials may be a pillow shape, an envelope shape, a pleated shape, a stick shape, a sheet shape, or any other suitable shape according to the application and purpose.

The molding container may be, for example, a blow container, an injection container, a vacuum molding container, or the like, and its forming material may be, for example, an olefin resin, a polyester resin, or a nylon resin.

For example, these containers are filled with the edible contents 3 which will be described in detail below, and then sealed, whereby the edible cold storage agent 1 is formed. The content 3 contains glucomannan and water as main components, and may further contain various food additives, gelling agents, thickeners, etc., if necessary.

Glucomannan is composed of D-glucose and D-
Mannose is a general term for polysaccharides containing mannose as a main constituent and is present in the stems of plants of the genus Konjac. So-called konjak mannan collected from the root of konjak is one example, and it is also separated from the hemicellulose fraction of some other softwood.

The edible cold storage agent 1 contains water as a main component together with such glucomannan. The mixing ratio of glucomannan and water is usually 0.5 to 15 parts by weight of glucomannan, 99.5 to 85 parts by weight of water, preferably 1 to 5 parts by weight of glucomannan and 99 to 95 parts by weight of water. If the blending ratio of glucomannan is less than 0.5 part by weight, the performance as a cold storage agent may not be sufficient. On the other hand, when the blending ratio of glucomannan exceeds 15 parts by weight, the texture of food may not be preferable.

Examples of food additives that may be contained in the contents 2 include salt, sand, pigments, fruit juices, and flavors. These various food additives may be used alone or in combination of two or more. When such a food additive is used, the mixing ratio of the food additive is a mixture of glucomannan and water 10
It is usually about 0.1 to 10 parts by weight with respect to 0 parts by weight. If this ratio is less than 0.1 part by weight, the effect of adding the food additive may not be sufficiently exhibited. On the other hand, if the amount is more than 10 parts by weight, the effect equivalent to that is not exhibited, and the flavor of the food may be deteriorated.

As the above gelling agent, for example, calcium hydroxide can be preferably used. Further, examples of the above-mentioned thickener include proteins and polysaccharides. More specifically, examples of the protein include gelatin, and examples of the polysaccharide include mannans such as galactomannan, elephant palm mannan and seaweed mannan, and glucans such as starch and cellulose. These various thickeners and proteins may be used alone or in combination of two or more.

When such a gelling agent or thickening agent is used, the proportion of the gelling agent added is about 0.02 to 2 parts by weight per 100 parts by weight of the mixture of glucomannan and water. The amount of the sticky agent is about 0.1 to 50 parts by weight. When the blending ratio of the gelling agent is less than 0.02 part by weight, the gelation of the content 3 may not proceed sufficiently. On the other hand, even if the amount is more than 2 parts by weight, the effect corresponding to that is not obtained, which is rather disadvantageous in terms of manufacturing cost. Further, if the mixing ratio of the thickener is less than 0.1 part by weight, the thickening effect may not be sufficiently exhibited. On the other hand, if it is more than 50 parts by weight, the texture may be rather deteriorated.

The edible cold storage agent 1 having such a constitution is
For example, after being cooled to a desired temperature in a freezer, it is stored in an adiabatic container together with an object to be cooled, such as fresh food, and used as a cold storage agent. After being used as a regenerator, as it is or after cooling again,
The content 3 may be taken out from the sealed container 2 and the content 3 may be eaten.

Next, an experimental example of the present invention will be shown. Experimental Example 1 3 parts by weight of glucomannan and 97 parts by weight of water were filled in a pouch made of a laminated film of a stretched nylon film (thickness 15 μm) and a vinyl acetate film (thickness 60 μm), and this was filled. An edible cold storage agent was prepared by sealing.

Next, the temperature of the edible regenerator is set to -2 by placing the edible regenerator in a freezer and cooling it for 5 hours.
After the temperature was set to 0 ° C., the edible cold storage agent was taken out from the freezer. Next, this edible cold storage agent was stored in a styrofoam heat insulation container together with raw ham, which is a cold storage object, and a cold storage test was conducted under the following conditions.

Container: Styrofoam (wall thickness 20 mm),
Inner volume: 2 liters Cooled object: prosciutto (500 g x 2) Outside air temperature: 26 ° C In this cooling test, the time until the temperature of the cooled object reached 10 ° C was measured, and it was 20 hours. From this, it was confirmed that this edible cold storage agent had a good cold insulation performance. Experimental Example 2 Glucomannan (2 parts by weight), fruit juice (0.5 parts by weight), glucose-fructose syrup solution (0.5 parts by weight), gelling agent (thickening polysaccharide) (1 part by weight), water (96 parts by weight) and a small amount of fragrance were added. A jelly-like edible cold storage agent was prepared.

Next, this edible cold storage agent was subjected to a cold insulation test under the same conditions as in Example 1 above to evaluate the cold insulation performance. As a result, it took 22 hours for the temperature of the object to be cooled to reach 10 ° C., and it was confirmed that the material to be cooled has a good cold insulating property.

Then, when the edible cold storage agent was taken out from the pouch and ate, it was confirmed that the edible cold storage agent had a jelly flavor and had good edibility.

[0027]

As is apparent from the above detailed description, according to the present invention, glucomannan and water are used as the main components of the contents to be filled in the sealed container. In addition to having the function of being edible, there is no risk of accidental ingestion, and because it has edible nature, it has excellent disposal characteristics, and is advantageous in terms of effective use of resources and environmental friendliness. An edible cold storage agent is provided that has advantages.
