Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a regenerator material used for keeping articles cold.

[0002]

2. Description of the Related Art Conventionally, as a cold storage material, a bag in which an aqueous solution of a synthetic paste such as polyvinyl alcohol or polyacrylic acid salt is packed is provided.

[0003]

However, when the above conventional regenerator materials are discarded after use, synthetic pastes such as polyvinyl alcohol and polyacrylate are not decomposed by microorganisms to cause environmental pollution, and a large amount of water is used. It is also difficult to incinerate because it is contained in. It is also possible to use a bag of konjak gelled with a conventional gelling agent such as lye, calcium hydroxide or sodium carbonate, but it can also be used as a cold storage agent, but when it is thawed when frozen In addition, the konjak processed product becomes frozen due to the roughness of the tissue and the change of water separation, and it loses elasticity and is difficult to reuse as the konjak processed product.

[0004]

Means for Solving the Problems The present invention provides a konjak processed product obtained by gelling a konjak refined powder and / or a konjak millet ground product with a stabilizer composed of a polysaccharide as a means for solving the above-mentioned conventional problems. It provides a bag of cold storage material.

Stabilizers used in the cold accumulating agent of the present invention include seaweed extracts such as agar, carrageenan, faserelan, alginates, propylene alginate, glycol esters, plant seed mucilages guar gum, locus bean gum, Tamarind seed polysaccharides, tara gum, plant resin mucilages gum arabic, tragacanth gum, karaya gum, plant fruit mucilage pectin, arabinogalactan, microbial mucilage xanthan gum, sclerogam vullan, dextran, animal protein Gelatin, albumin, casein, vegetable protein soybean protein, wheat protein cellulose and its derivatives carboxymethyl cellulose, methyl cellulose, microcrystalline cellulose and starch and its derivatives starch, starch Phosphoric acid esters, polysaccharides sodium starch glycolate, etc. are used. It is desirable that the polysaccharide has a thickening property. The above stabilizers may be used alone or in combination of two or more. The above-mentioned polysaccharide is usually used in an amount of about 5 to 20% by weight.

The konjak source used in the cold accumulating material of the present invention includes konjak crushed raw or smashed after crushing, or konjac yam cut, dried and ground to obtain coarse powder, It is possible to use a refined powder obtained by further wind-selecting the rough powder and taking out mannan particles, or a mixture thereof.

[0007]

The cold accumulating agent of the present invention is a gel of konjak refined powder or konjak potato milled with a water-soluble polymer, so that it is easy to handle and has an excellent cold accumulating effect. Further, the regenerator material of the present invention is konjac refined flour and /
Alternatively, since it is composed of ground material of konjac potato, water-soluble polymer such as animal and plant polysaccharides and proteins, and water, it can be decomposed by microorganisms when used and discarded without causing environmental pollution. In addition, the above water-soluble polymer imparts protein stability under acidic conditions, increases viscosity and binding property, stabilizes emulsion particle system, and promotes gelation of foods to which the water-soluble polymer is added. You can Further, the affinity of the water-soluble polymer with water reduces the proportion of free water, reduces the size of ice crystals when frozen, and prevents the roughening of tissues and the change in water separation when frozen and thawed. It can be done and maintains the gel state before freezing,
If the above-mentioned cold storage agent becomes unnecessary after freezing and thawing, it can be used as a jelly, a drink, or a konjak processed product for food.

【Example】

[Example 1] 5% by weight of carrageenan was added as a stabilizer to a mixture obtained by kneading a mixture containing 3% by weight of konjak refined powder and 97% by weight of water to swell the konjak refined powder, and using citric acid. The pH was adjusted to 3.5. The mixture is filled in a polyethylene bag and the bag is vacuum packed. Then, the bag is roasted to gel the mixture in the bag.

[Example 2] 1 kg of konjac potato was boiled and then ground, and 60 g of furceleran as a stabilizer was added to the ground konjak ground material and kneaded, and the pH was adjusted to 3.0 using a jump. I adjusted. The kneaded product is filled in a polypropylene bag, and the bag is vacuum-packed. Then, the bag is roasted to gel the mixture in the bag.

[Cool Storage Effect] A thermocouple was attached to the cold storage agents prepared in Examples 1 and 2, placed in a freezer to be frozen, and then allowed to stand at room temperature, and the temperature change of the cold storage agents was measured.
The result is shown in FIG. As is clear from FIG. 1, the cold accumulating agent prepared in Example 1 maintained 0 ° C. for 3 hours from 30 minutes to 3 hours 30 minutes after standing, and showed a high cold accumulating effect. Also, the cold storage agent prepared in Example 2 was maintained at around 0 ° C. for 1 hour from 30 minutes to 1 hour 30 minutes after being left to stand, and then heated. From the above, it became clear that the cold storage effect of the cold storage agent of the present invention is sufficiently satisfactory.

The cold storage agents manufactured in Examples 1 and 2 are cooled in, for example, a household refrigerator or a freezer and used as an ice pillow, or applied to an inflamed affected area, or vegetables in a cooler box. If it is stored together with fish, meat, etc., it can be transported to campgrounds etc. while maintaining the freshness of the vegetables, fish, meat etc. Also, as a storage box for fish caught by storing a cool storage agent in a cooler box. Can also be used. When the regenerator is no longer needed, the regenerator can be used as a jelly, a drink, or a konjak processed product for consumption. In addition to the above, the regenerator can be used for various purposes.

[0012]

Therefore, in the method of the present invention, it can be decomposed by microorganisms even when it is discarded after use and does not pollute the environment, and when it becomes unnecessary after use, it is used as a jelly, drink or konjak processed product. A regenerator that can be used for food can be provided.
