〔産業上の利用分野〕
本発明は、氷と同じ各種の用途に供することが
でき、しかも、氷に比べて保冷効果に優れ、繰り
返し使用ができ、かつ取り扱いに至便な保冷材に
関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention can be used for the same various purposes as ice, has a better cooling effect than ice, can be used repeatedly, and is easy to handle. Regarding cold insulation materials.
氷は、解凍水によつてその周辺や被保冷物を濡
らし、また、その解凍水が被保冷物特に食品の品
質を損なうことさえある。
The thawing water of ice wets the surrounding area and the objects to be kept cold, and the thawing water may even impair the quality of the objects to be kept cool, especially food.
本発明の目的は、このような欠点を解消すると
ともに、凍結と解凍を繰り返させ何回でも使用で
きる保冷材を提供することにある。 An object of the present invention is to eliminate such drawbacks and to provide a cold insulating material that can be repeatedly frozen and thawed and used any number of times.
上記目的を達成するために、本発明保冷材は、
水に寒天とポリアクリル系合成ポリマーを混合し
てなるものである。
In order to achieve the above object, the cold insulating material of the present invention:
It is made by mixing agar and polyacrylic synthetic polymer with water.
水に寒天を単独使用した場合、この寒天には保
水力がないため、その混合割合がどの様なときで
も解凍時には水分離を起こし、かつ、それが2.5
％を超えると製品の透明度が失われる（カラギー
ナンの種類によつては１％でも透明度を失うもの
がある）が、その点、ポリアクリル系合成ポリマ
ーは、単独使用しても製品の透明度を損なうこと
なく、保水力が十分で水分離を起こさない。 If agar is used alone in water, this agar has no water retention capacity, so no matter what the mixing ratio, water separation will occur during thawing, and it will be 2.5
%, the product loses its transparency (some types of carrageenan lose transparency even by 1%), but polyacrylic synthetic polymers, on the other hand, do not impair the transparency of the product even when used alone. It has sufficient water retention capacity and does not cause water separation.
しかし、例えばポリアクリル酸ソーダの食品へ
の使用は、食品衛生法使用基準によつて食品中含
有量を0.2％以下と定められている。 However, for example, the use of sodium polyacrylate in foods is stipulated by the Food Sanitation Law Usage Standards to limit its content in foods to 0.2% or less.
実験によれば、水に寒天を1.5〜1.8％、ポリア
クリル酸ソーダを0.3〜0.5％の範囲で混合した場
合、製品は凍結時に半透明になるが、解凍時間は
氷の1.5倍以上になる。 Experiments have shown that when water is mixed with agar in the range of 1.5-1.8% and sodium polyacrylate in the range of 0.3-0.5%, the product becomes translucent when frozen, but the thawing time is more than 1.5 times that of ice. .
この場合において、寒天の混合割合を1.5％以
下にするとゲル強度が弱くなり、必然的に解凍時
間が短くなる。また、ポリアクリル酸ソーダの混
合割合を0.3％以下とすると保水力が弱まり水分
離現象を起こす。 In this case, if the mixing ratio of agar is 1.5% or less, the gel strength will be weakened and the thawing time will inevitably be shortened. Furthermore, if the mixing ratio of sodium polyacrylate is 0.3% or less, the water retention capacity will be weakened and a water separation phenomenon will occur.
寒天の混合割合が1.8％以上になると、製品は
凍結時はもちろん解凍後にも不透明となる。ま
た、ポリアクリル酸ソーダの混合割合が0.5％以
上になると、ゲル中に大きな気泡が発生し、製品
凍結時に細かい結晶となる。 When the agar mixture ratio exceeds 1.8%, the product becomes opaque not only when frozen but also after thawing. Furthermore, if the mixing ratio of sodium polyacrylate exceeds 0.5%, large air bubbles will occur in the gel, which will turn into fine crystals when the product is frozen.
したがつて、寒天及びポリアクリル酸ソーダの
水に対する混合割合は、使用目的に応じて適宜変
更するのがよいと認められるが、好ましくはそれ
ぞれ0.1〜２％の範囲内である。 Therefore, it is recognized that the mixing ratio of agar and sodium polyacrylate to water should be changed as appropriate depending on the purpose of use, but each is preferably within the range of 0.1 to 2%.
本発明保冷材を単体で繰り返し使用する場合、
外気や食品に触れるため、防腐剤または殺菌剤を
添加しておくとよい。 When using the cold insulating material of the present invention alone,
Since it comes into contact with outside air and food, it is a good idea to add a preservative or disinfectant.
また、本発明保冷材を合成樹脂フイルム製袋等
の包装体に封入しておくと、取り扱いに便利であ
る。 Furthermore, it is convenient to handle the cold insulating material of the present invention if it is enclosed in a package such as a synthetic resin film bag.
本発明保冷材は、寒天を混合しているので、氷
点降下性が付与され氷よりも低温になり、また熱
伝導性を抑制し保冷効果が改善される。
Since the cold insulating material of the present invention contains agar, it is given freezing point lowering properties and becomes lower temperature than ice, and also suppresses thermal conductivity and improves the cold insulation effect.

吸収ができる。 By mixing polyacrylic synthetic polymer,
It has a water-retaining ability and will not spit out the water it has absorbed even if pressure is applied. Therefore, water separation does not occur even after thawing, and on the contrary, it can absorb drips and condensation from objects to be refrigerated, such as food.

たところ図面に示すとおりであつた。
While stirring water, agar and sodium polyacrylate powder are mixed into it at a ratio of 99.0%, 0.8%, and 0.2%, and stirred well to completely dissolve and sol.
After that, it is heated to 80℃ or higher, then cooled and turned into jelly. The characteristics were as shown in the drawings when compared with the following comparative example.

Cool for about 5 hours, take out after freezing, and No. 1~
We put No. 3 in containers with water temperature of 16℃ and 100 c.c., and examined the change in water temperature and thawing situation. We found that, especially in No. 2, which only had agar, the water separated as soon as it thawed, and the whole At the time of thawing, about 10% syneresis occurred, but no syneresis was observed in the jelly containing No. 1 sodium polyacrylate even after thawing.

食品の品質を損なうこともない。 As in No. 1, if the sodium polyacrylate meets the standards for use under the Food Sanitation Law, it can be used in direct contact with food, just like ice. In this case, since there is no separation of water as described above, the quality of the food is not impaired.

Therefore, it is advantageous for use, for example, in refrigerated objects to be transported over long distances.

As is clear from the above, since the cold insulation material of the present invention is mixed with agar, it is given a freezing point depressing property and becomes lower than ice, and also suppresses thermal conductivity and improves the cold insulation effect. At the same time, the mixture of polyacrylic synthetic polymers provides water-retaining power, and even if pressure is applied, the water that has been absorbed will not be expelled. Therefore, there is no water separation even after thawing, and on the contrary, it can absorb drips and condensation from objects to be refrigerated, such as food, and it has the great advantage of being able to be used over and over again. .
