A sterilizing method for removing a sterilizing solution by spraying is described.
In the 8931 publication, a bactericide consisting of a heated aqueous hydrogen peroxide solution or an aqueous solution of sodium hypochlorite is sprayed into and out of the container, and then the bactericide is dried by blowing hot air on the inner and outer walls of the container. A method is described in which the attached germicide is washed and removed with washing water composed of sterile water.

という問題があった。However, in any of the above methods, the temperature of the disinfectant or hot water is 60 ° C to 85 ° C.
℃ and high temperature, it can be used only for containers with heat resistance, and the range of choice of containers is narrowed, the process of sterilization becomes complicated, it takes time and effort, so it is completed There is a problem that the product becomes expensive.

きる方法が求められていた。On the other hand, it is conceivable to lower the temperature of the disinfectant by increasing the concentration of the disinfectant or by using a disinfectant having a strong disinfecting ability such as peracetic acid.
Sterilization of PET containers before filling beverages is performed using a germicide composed of a mixed solution of peracetic acid and hydrogen peroxide solution. However, when a beverage is filled in a container sterilized using the above-described sterilization method, molds and the like are generated on the finished product, although only occasionally, the mold spores and the like that cannot be sterilized in the container and multiply remain. As a result, the container may have no value as a product, and there has been a demand for a method that can completely sterilize a container at room temperature.

の重要性がますます高まってきている。Further, in the recent food manufacturing industry, there is a demand for fresher foods such as fresh taste and freshness, so that microbial contamination is likely to occur. As described above, even in a situation where microbial contamination is likely to occur, the importance of a sterilization treatment previously applied to a container to completely suppress microbial contamination is increasing.
【０００８】そこで、本発明は、上記問題点を鑑みて、

ことを目的としてなされたものである。Therefore, the present invention has been made in view of the above problems,
It is an object of the present invention to provide a sterilization method for a container that can completely sterilize microorganisms attached to the container without applying heat.

剤を用いた殺菌工程とを備えている構成とした。In order to achieve the above object, a method for sterilizing a container according to the present invention is characterized in that, in the step of sterilizing the container using a sterilizing agent, a sterilizing step using a peroxide-based sterilizing agent is performed. And a sterilizing step using a sterilizing agent containing decyldimethylammonium chloride (hereinafter referred to as “DDAC”) as a main component.

％の濃度になるまで希釈して使用するのが好ましい。[0010] The peroxide-based disinfectant having the above structure is not particularly limited. For example, a disinfectant containing peroxide as a main raw material such as aqueous hydrogen peroxide, peracetic acid, or a mixture thereof is used. Agents. The peroxide-based disinfectant preferably has a peroxide content of 0.01 W / V% or more, particularly 0.05 W / V% to 0.5 W / V.
It is preferable to use it after diluting it to a concentration of%.

If the concentration is lower than V%, the bactericidal effect may be insufficient. If the concentration is higher than 0.5 W / V%, there is a problem in terms of handling safety or workability. The bactericide containing DDAC as a main component is used after being diluted until the DDAC content becomes 0.01 W / V% or more, preferably from 0.05 W / V% to 0.5 W / V%.

If the concentration is lower than V%, the bactericidal effect may be insufficient. If the concentration is higher than 0.5 W / V%, there is a problem in terms of handling safety or workability. Further, the treatment temperature with the disinfectant is not particularly limited, but is desirably set to 30 ° C. or higher. When disinfecting a container having no heat resistance, it is preferable to set the temperature in the range of 30 ° C. to 65 ° C. desirable. When the temperature when using a disinfectant is lower than 30 ° C,
If the temperature is higher than 65 ° C., depending on the material of the container, the temperature may exceed the range of heat resistance, thereby causing an adverse effect such as deformation of the container.

処理に時間を要してしまう恐れがある。[0013] Further, the time for the action of the bactericide is preferably 5 to 30 seconds for a peroxide-based bactericide, and 5 to 30 seconds for a bactericide containing DDAC as a main component. That is, if the time to act the disinfectant is less than 5 seconds, there is a possibility that the container may not be sufficiently disinfected,
Even if it is longer than 30 seconds, the sterilizing effect of the container does not change and may lead to waste of time and a sterilizing agent, and the sterilizing agent may remain in the container, and the time required for cleaning must be increased. Therefore, there is a possibility that the sterilization treatment may take a long time.
