【発明の詳細な説明】 ［産業上の利用分野］ 本発明は低濃度の過酸化水素による殺菌に適した材
料、容器並びに前記材料、容器の殺菌方法に関するもの
である。Description: TECHNICAL FIELD The present invention relates to a material and a container suitable for sterilization with low-concentration hydrogen peroxide, and a method for sterilizing the material and the container.
［従来の技術］ 食品無菌充填包装は、種々実用化されており、まず、
食品を充填する容器、または容器を形成する材料を殺菌
して、これを用いて無菌状態の食品を充填して、これを
無菌状態の雰囲気で密封する方式の無菌充填包装が一般
的に行われている。[Prior art] Food aseptic filling and packaging have been put to practical use.
Aseptic filling and packaging of a type in which a container for filling food or a material forming the container is sterilized, filled with aseptic food using this, and sealed in a sterile atmosphere is generally performed. ing.
この方式において、容器または材料を過酸化水素（以
下H2O2と称す）を用い、さらに加熱することにより殺菌
するのが大事であった。In this method, it was important to sterilize the container or material by using hydrogen peroxide (hereinafter, referred to as H 2 O 2 ) and further heating.
食品を充填する前に、容器または材料をH2O2を用いて
殺菌するには約35％の濃度のH2O2をスプレー等で吹き付
け、さらに、ホットエアにより殺菌を行うと共に、H2O2
を分解除去していた。Before filling the food, container or material to be sterilized with H 2 O 2 is blown H 2 O 2 at a concentration of about 35% in the spray or the like, further, performs sterilized by hot air, H 2 O Two
Was decomposed and removed.
また、35％の濃度H2O2を80℃の高温状態とし、H2O2を
スプレー等で行い同様の処理を行っていた。一方、食品
衛生面から、前記H2O2は、殺菌処理後残留がないように
容器、または材料から除去しなければならない。Further, the same treatment was performed by setting the concentration of H 2 O 2 at 35% to a high temperature of 80 ° C. and spraying H 2 O 2 by spraying or the like. On the other hand, from the viewpoint of food hygiene, the H 2 O 2 must be removed from the container or the material so that there is no residue after the sterilization treatment.
ところが、H2O2を吹き付けた後、エアホットで処理す
ると水分が蒸発し、H2O2の残留してしまう危険があっ
た。However, when H 2 O 2 was sprayed and then treated with air hot, there was a danger that water would evaporate and H 2 O 2 would remain.
そこで、H2O2の残留を少なくするために、低濃度のH2
O2（１％）とホットエリアを併用することも提案されて
いるが、殺菌効果が低い、また、さらに殺菌効果を高め
るため、前記処理のほかに、紫外線を照射することも行
われているが、十分な殺菌効果が得られないのが現状で
あった。Therefore, in order to reduce the residual H 2 O 2, the low concentration of H 2
It has also been proposed to use O 2 (1%) in combination with a hot area, but in order to reduce the sterilizing effect and further enhance the sterilizing effect, irradiation with ultraviolet rays has also been performed in addition to the above treatment. However, at present, a sufficient bactericidal effect cannot be obtained.
［発明が解決しようとしている問題点］ 上記殺菌方法において、十分な殺菌効果を得ようとす
れば、35％の比較的高濃度のH2O2溶液を塗布しなければ
ならず、このH2O2を除去する為には多量のホットエアー
噴射や水シャワーを行わなければならず不経済であるば
かりでなく、容器の劣化やH2O2の残留の恐れが生じてい
た。In [INVENTION you are trying to problems solved] above sterilization method, in order to obtain a sufficient sterilization effect, it is necessary to apply the 35% relatively high H 2 O 2 concentrations solution, the H 2 In order to remove O 2 , a large amount of hot air injection or water shower had to be performed, which was not only uneconomical, but also caused deterioration of the container and the possibility of H 2 O 2 remaining.
そこで本発明の目的は、低濃度のH2O2を用いても十分
な殺菌効果を発揮し、しかも残留の問題を解消した殺菌
方法を提供するものである。Accordingly, an object of the present invention is to provide a sterilization method which exhibits a sufficient sterilizing effect even when a low concentration of H 2 O 2 is used, and which eliminates the problem of residual.

ン結合させた合成ゼオライトを表面に固定した材料また
は容器に過酸化水素を塗布する殺菌方法であって、前記
過酸化水素が10％以下の濃度であることを特徴とする材
料、容器の殺菌方法である。[Means for Solving the Problems] The present invention is a sterilization method of applying hydrogen peroxide to a material or a container having a surface immobilized with a synthetic zeolite in which an ionized transition metal is ionically bonded in a skeletal structure, A method for sterilizing a material or a container, wherein the concentration of hydrogen peroxide is 10% or less.
［作用］ H2O2は、遷移金属イオンによりヒドロキシラジカルを
生成することが知られている。このヒドロキシラジカル
は高い反応性を持つとが知られており、菌体のアミノ酸
残基及び脂肪酸を攻撃することにより殺菌効果を発揮す
る。[Action] H 2 O 2 is known to generate a hydroxy radical by a transition metal ion. This hydroxyl radical is known to have high reactivity, and exerts a bactericidal effect by attacking amino acid residues and fatty acids of bacterial cells.
また、合成ゼオライト骨格構造内にイオン結合された
遷移金属イオンは、ほとんど溶出が認められない。Also, almost no elution of transition metal ions ionically bonded in the synthetic zeolite framework structure is observed.
すなわち、イオン化した遷移金属を骨格構造内にイオ
ン結合させた合成ゼオライトを表面に固定した容器に、
10％以下のH2O2を少量塗布することにより、ヒドロキシ
ラジカルを発生させ、このヒドロキシラジカルを発生さ

とにより高い殺菌効果が得られる。In other words, a container in which a synthetic zeolite in which ionized transition metals are ion-bonded in a skeleton structure is fixed on the surface,
By applying a small amount of 10% or less of H 2 O 2 , a hydroxyl radical is generated, and the hydroxyl radical is generated, and the hydroxy radical is allowed to act directly on the cells to obtain a high bactericidal effect.
この際、H2O2溶液に容器を浸漬して、H2O2を塗布する
方法によって殺菌した場合においても、合成ゼオライト
より溶出される遷移金属は、ほとんど無い為、H2O2溶液
には影響を与えず、容器表面のH2O2のみが、ヒドロキシ
ラジカルとなり、大なる殺菌効果を発揮する。At this time, even if the container is immersed in the H 2 O 2 solution and sterilized by the method of applying H 2 O 2 , there is almost no transition metal eluted from the synthetic zeolite, so the H 2 O 2 solution Has no effect, and only H 2 O 2 on the surface of the container turns into a hydroxyl radical and exerts a great bactericidal effect.
また残留の問題は、このヒドロキシラジカルは反応性
が大きく短命であり、10％H2O2溶液を用いる事により、
ホットエアーにより容易に分解除去できる。Also, the problem of residual is that this hydroxyl radical is highly reactive and short-lived, and by using a 10% H 2 O 2 solution,
It can be easily decomposed and removed by hot air.
