【発明の詳細な説明】
〔産業上の利用分野〕
本発明は殺菌方法に関し、特に食品や包装材料に付着し
ている微生物の殺菌、医薬品、食品及びパイオニ場など
の空中浮遊菌の殺菌並びに水の殺菌に有利に適用するこ
とができる殺菌方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a sterilization method, and in particular to sterilization of microorganisms attached to foods and packaging materials, sterilization of airborne bacteria in pharmaceuticals, foods, pioneering places, etc. The present invention relates to a sterilization method that can be advantageously applied to sterilization.
従来、上述した対象物の殺菌には紫外線を照射すること
Kよって行うのが一般的であった。Conventionally, the above-mentioned objects have generally been sterilized by irradiating them with ultraviolet light.
従来の紫外線照射による殺菌では、酵母類は紫外線に対
して抵抗性をもっているので強力な紫外線か紫外線照射
時間を長く採る必要があシ、エネルギーの損失や作業環
境の悪化をもたらすという問題点があった。また、紫外
線のとどかない凹凸の多−物体では完全殺菌ができない
という不具合もあった。In conventional sterilization using ultraviolet irradiation, since yeast are resistant to ultraviolet rays, it is necessary to use strong ultraviolet rays or to use ultraviolet rays for a long time, which causes problems such as energy loss and deterioration of the working environment. Ta. Another problem was that it was impossible to completely sterilize objects with many uneven surfaces that the ultraviolet rays could not reach.
上記技術水準I/c鑑み、本発明は従来技術におけるよ
うな不具合のない殺菌方法を提供しようとするものであ
る。In view of the above state of the art I/c, the present invention seeks to provide a sterilization method that is free from the problems encountered in the prior art.
本発明者らは紫外線を照射するとオゾンが発生すること
にヒントを得、そのヒンNC基づいて本発明を完成する
に至った。すなわち、本発明は被殺菌体に対し、紫外線
を照射しながらエチレンを供給することを特徴とする殺
菌方法である。The present inventors got a hint from the fact that ozone is generated when irradiated with ultraviolet rays, and completed the present invention based on the HinNC. That is, the present invention is a sterilization method characterized by supplying ethylene while irradiating the object with ultraviolet rays.
本発明において供給するエチレンは紫外線照射によって
生成したオゾンと等量のエチレン量にするのがよい。In the present invention, the amount of ethylene to be supplied is preferably equal to that of ozone produced by ultraviolet irradiation.
紫外線の照射によって発生するオゾンとエチレンが下記
のように反応して
サイドを生成する。このエチレンオキサイドは殺菌剤と
して知られているものであるが、本発明はエチレンオキ
サイドを供給するのでなく、殺菌を必要としている部所
でエチレンオキサイドを生成させるのである。この生成
した(発生基と云われる)エチレンオキサイドは殺菌力
が強力である。また紫外線によシ副生じたオゾンは人体
に有害であるが、エチレンの添加はこのオゾンを完全に
分解除去することKもなる。Ozone and ethylene generated by ultraviolet irradiation react as shown below to generate side. This ethylene oxide is known as a disinfectant, but the present invention does not supply ethylene oxide, but rather generates ethylene oxide at the location where disinfection is required. This generated ethylene oxide (referred to as a generating group) has strong bactericidal activity. Furthermore, ozone produced by ultraviolet rays is harmful to the human body, but the addition of ethylene also completely decomposes and removes this ozone.

10'/2 spores were attached to the surface of a usSpore) and dried. High performance UV germicidal lamp (output IK
A curve (a) as shown in FIG. 1 was obtained by irradiating with W, intensity 200 mW/i). That is, the number of bodies on the image side is 101 even after 3 seconds of irradiation, which is effective but not perfect. Also,
After 5 seconds of irradiation, complete sterilization was not achieved.
〔実施例〕

なオゾンも検出されなかった。[Example] Under the same conditions as Comparative Example 1, 10 p of ozone was applied 5 seconds after irradiation.
Since pm was present, 10 ppm of H,0=OH was supplied and ultraviolet rays were irradiated. As shown in the (b1 curve) in Figure 1, the results were as follows: k, 1 second of irradiation was insufficient, but 1 second after 3 seconds.
It turned out that it was 0°. No ozone, which is harmful to the human body, was detected 5 seconds after irradiation.
さらに高性能紫外線殺菌ランプの出力を半減(100m
W/3”)としてもエチレンを共存させると3秒照射後
には全く同様な効果が認められた。当然、人体に有害な
オゾンも完全に分解されていた。Furthermore, the output of high-performance ultraviolet germicidal lamps was halved (100 m
When ethylene was coexisted with W/3'', exactly the same effect was observed after 3 seconds of irradiation. Naturally, ozone, which is harmful to the human body, was also completely decomposed.
