Field of the Invention The present invention relates to a sterilization method, and more particularly to a sterilization method for a variety of objects to be treated such as food containers, manufacturing machines, environment, etc. by using electrolytic acid water in combination with ultraviolet rays.

必要となる。2. Description of the Related Art It is well known that hydrogen peroxide solution has a sterilizing effect, and hydrogen peroxide solution has been conventionally used for sterilizing food containers. However, hydrogen peroxide solution alone is effective. For sterilization, a high concentration of 35% and a temperature of 80 ° C,
High temperature is required. Therefore, great care must be taken when handling.

て、この問題点は、過酸化水素単用の場合はもとより、
紫外線照射処理との併用の場合にも同様に生じるもので
ある。As described above, hydrogen peroxide is often used as a sterilizing agent for food containers and the like. However, the hydrogen peroxide sterilizing agent is dangerous to handle, and cannot be used in foods. It has a serious problem of hydrogen oxide residue and the risk of contamination. Hydrogen peroxide is not only stable and requires careful handling, but also causes irritation when it comes into contact with the outer skin, especially eyes and mucous membranes, which poses a safety issue for workers. Since a person handles a large amount of hydrogen peroxide, he / she is always in danger, and there has been a demand for the development of a highly safe sterilization system. And this problem is not only in the case of using hydrogen peroxide alone,
The same occurs when used in combination with the ultraviolet irradiation treatment.
【０００６】そこで、このような問題を顕在化させない
ために、従来より、過酸化水素を殺菌剤として用いる場

Hydrogen peroxide sprayer → dryer → sterilized air supply device → exhaust device. However, these facilities are expensive, and moreover, a lot of labor, time, and cost are required for maintaining and maintaining these functions normally, and still not completely satisfactory results are obtained.

It was made for the purpose of newly developing a highly safe industrial sterilization system.

有するものではない。Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors have focused their attention on electrolytic acid water. Although it has been recognized that electrolyzed acidic water has bactericidal properties, it does not have a high bactericidal effect on all microorganisms.

の新知見を得た。However, when electrolyzed acidic water is used in combination with ultraviolet ray treatment, a very high bactericidal effect is unexpectedly obtained, and the effect is the same as when hydrogen peroxide solution is used, and Since it uses electrolytic acid water instead of hydrogen peroxide water, it is highly safe, does not pose a risk to workers, and does not require a ventilator for evaporated bactericide, which reduces equipment costs and maintains it. We obtained new knowledge that it is easy to manage and that it is an extremely industrial sterilization system.

The ubtilis spores were evenly smeared (10 6 cfu / packaging material) and dried in a desiccator to give test pieces. The electrolyzed acidic water is Aquatide NDX-250 manufactured by Omco Co., Ltd.
Prepared using KMW. 0.17 ml of electrolyzed acidic water (pH 5.0 to 6.0, effective chlorine concentration 70 ppm) was sprayed on the test piece, and after holding for a predetermined time, a reaction stopper (Tween 80 added sodium thiosulfate solution) 10 m immediately
It was put in a stomacher bag containing 1 to deactivate it. After deactivation, the number of surviving bacteria in the recovered liquid was measured. Similarly, 0.17 ml of 0.1% hydrogen peroxide solution is sprayed, and after holding for a predetermined time,
It was put in a stomacher bag containing 9 ml of a reaction terminator (catalase solution) to be inactivated. After the inactivation, Tween 80 was added and collected, and the number of surviving bacteria in the collected liquid was measured.

After stopping, the number of surviving bacteria in the recovered liquid was measured. The number of surviving bacteria is
The logarithm of the number of bacteria (cfu / 25 cm 2 ) on the test piece was shown. As a result, electrolytic acid water and 0.1% hydrogen peroxide solution alone did not have a sterilizing effect. The combined use of ultraviolet irradiation increased the sterilizing effect of electrolytic acidic water and 0.1% hydrogen peroxide solution. In addition, the bactericidal effect of the electrolyzed acidic water at that time was equivalent to that of hydrogen peroxide solution (Fig. 1).
