More specifically, the present invention uses a production raw material containing nitrogen oxides in producing an ultraviolet-generating substance. Furthermore, the present invention provides an adsorption base material on which air, oxygen, nitrogen dioxide, dinitrogen tetroxide, or a mixture is adsorbed and retained, is irradiated with ultraviolet rays, and the adsorption base material is used as an ultraviolet generating substance to generate the adsorbent group. The material absorbs and holds the
In addition, we also provide an adsorption/retention material that can release ultraviolet rays and a method for producing it, as well as a microorganism suppression method that is useful for sterilizing microorganisms or suppressing their growth, while also maintaining the freshness of food using the adsorption/retention material. It is related to.

を多量に生成することはなかった。When producing UV-generating substances, it has been difficult to find a production method that uses specific production raw materials to obtain a larger amount of a specific product. In particular, regarding the generation of ozone, which is a typical UV-generating substance, low-pressure mercury lamps and high-pressure mercury lamps, which use air as a raw material and use quartz as an arc tube, have traditionally been used. The ultraviolet rays were produced using light with a wavelength of 185.254 nm, but the raw materials for the production were specified and supplied, and the ultraviolet rays were not produced in large quantities.

た。Regarding the use of ozone, there are various ways to use it as a disinfectant, disinfectant, decolorizer, deodorizer, oxidizing agent, etc., but in all of them, ozone is generated with an ozone generator,
It was used by blowing ozone-containing gas or by blowing air through a vent pipe. Ozone has a unique pungent odor, is unstable, and can irritate the mucous membranes of the human body.
It is said that it is not safe to breathe even dilute ozone-containing air for long periods of time, and it is rare for humans to be exposed to ozone contamination if ozone is generated and then transported by blowing or blowing air. Moreover, due to its unstable nature, there is also loss due to movement, which is not desirable.

た。Traditionally, ozone was generated and used after it was generated, but ozone was not generated from the beginning and ozone was used.
An ozone-generating raw material gas such as air, oxygen, nitrogen dioxide, dinitrogen tetroxide, or a mixture is adsorbed and retained on an adsorption base material, and the adsorption base material is moved to any place where ozone is used. At no time has the adsorption substrate been irradiated with ultraviolet rays to generate ozone for use.

その方法は、極めて限られたものとなる。On the other hand, in the food industry, in order to prevent microbial contamination, blocking microorganisms through packaging is commonly used, but the packaging material does not come into direct contact with the packaged material. Microorganisms that are often attached to the inner surface of the packaging material may cause secondary contamination of the packaged material and have an adverse effect on it. In order to prevent these contaminations, it is sufficient to sterilize the packaging material in advance, or sometimes it is preferable to sterilize both the packaging material and the packaged material at the same time after packaging. However, a disinfectant or disinfectant that can sterilize both at the same time,
The method is extremely limited.

However, in the case of vacuum packaging, it is difficult to suppress anaerobic bacteria that proliferate in the absence of oxygen, and in the case of gas-filled packaging, the gas to be filled depends on the type of packaging material and material to be packaged. It is difficult to select an appropriate gas, and there is a problem that these gases have little effect on actively suppressing microorganisms.

微生物抑制方法を提供しようとするものである。The present invention uses a gas containing nitrogen oxides as a raw material,
In addition to the method of producing ultraviolet rays and the use of ozone, which can be harmful, we use an adsorption base material that adsorbs and retains the ozone-generating raw material gas, and package it together with the packaged materials to avoid ozone pollution. In the food field, for example, in the food field, the food itself and its packaging materials can be sterilized at any stage to suppress the growth of microorganisms. It is an object of the present invention to provide a material for adsorbing and retaining ultraviolet rays that can be produced without remaining on foods and packaging materials, and a method for inhibiting microorganisms using the material.
〔課題を解決するための手段・作用〕
本発明の紫外線生成物質生成方法は、窒素酸化物類を含
有した気体を生成原料に用いるものである。窒素酸化物
類のなかでもより好ましくは、二酸化窒素、或いは四酸
化二窒素又は混合物である。[Means and effects for solving the problems] The method for producing an ultraviolet ray generating substance of the present invention uses a gas containing nitrogen oxides as a production raw material. Among nitrogen oxides, nitrogen dioxide, dinitrogen tetroxide, or a mixture is more preferred.
例えば、二酸化窒素を含有した空気に紫外線を照射する

化窒素になり、紫外線の照射を受けることになるので、
−酸化窒素分子としてほとんど残らず、結果的に多量の
オゾンを生成することができる生成方法である。For example, by irradiating air containing nitrogen dioxide with ultraviolet light, the nitrogen dioxide dissociates to produce equivalent amounts of nitrogen monoxide molecules and oxygen atoms. Oxygen atoms quickly become ozone molecules, while -nitrogen oxide molecules are oxidized to nitrogen dioxide again and are exposed to ultraviolet rays.
- This is a production method that leaves almost no nitrogen oxide molecules and can produce a large amount of ozone as a result.

することができると云われている。The base material used in the ultraviolet ray generating substance adsorption/retention material of the present invention is made of an adsorbent having at least one kind of adsorption ability. There is no particular limitation on the type of adsorbent as long as it is effective for achieving the purpose of the present invention.
The adsorbent preferred according to the invention is glassy, nearly transparent silica gel. Generally, ozone adsorbed on silica gel, activated alumina, or zeolite is somewhat unstable at room temperature, and the adsorption rate and decomposition rate of ozone are approximately the same, but at low temperatures below 0°C. Under these conditions, the decomposition of ozone in silica gel, activated alumina, or zeolite is extremely small and can be almost ignored. , it can be released gradually, and when silica gel is used as an adsorbent, the resulting substrate has a density of 0.09% by weight relative to its weight at 0°C or below.
It is said that it can adsorb and hold % to 6.0% of ozone and gradually release it.

に、当該吸着基材から放出される。In order to make the adsorption base material according to the present invention adsorb and hold air, oxygen, nitrogen dioxide, dinitrogen tetroxide, or a mixture, which are raw material gases for ozone generation, the adsorption base material is placed in a sealed packaging material or container in advance. The base material is brought into contact with the ozone-generating raw material gas, and is caused to adsorb and hold the ozone-generating raw material gas. The temperature and pressure at this time may generally be normal temperature and normal pressure, but in general, the adsorption substrate is first subjected to a reduced pressure treatment to desorb the other adsorbed gases, and then It is preferable to bring this into contact with the ozone-generating raw material gas at a low temperature. At this time, if it is brought into contact with an adsorption substrate under pressure, the amount of adsorption increases. By irradiating this base material with ultraviolet rays,
The ultraviolet rays penetrate all the way to the inside of the transparent adsorption base material, and change the adsorbed and retained substance adsorbed and held in the pores into an ultraviolet ray generating substance, which becomes an ultraviolet ray generating substance and is adsorbed and held. In other words, in the case of air or oxygen, ultraviolet rays, especially light around 185 nm, are absorbed by the oxygen in the air or oxygen itself, and generate ozone, which is an ultraviolet ray generating substance. to make. This ozone absorbs light near 254nO+ well and decomposes into excited oxygen atoms, but both ozone and
Also known as ozone decomposition products. Depending on the air used as the raw material, other substances are known to be generated, such as hydroxyl, hydroperoxy radical, peroxyacetyl nitrate, and hydrogen peroxide. Further, since the ultraviolet generating substance adsorbed and held on the adsorption base material is adsorbed and held, it is released from the adsorption base material gradually or all at once, depending on the adsorption underwear.

て光量の増減を行なってもよい。The method of producing the ultraviolet ray generating substance adsorption/holding material of the present invention is to produce the material by irradiating ultraviolet rays onto the adsorption base material on which the ozone generating raw material gas is adsorbed and held. Irradiation of ultraviolet rays is by direct irradiation,
Indirect irradiation may be used, or in order to avoid heat radiation, light conduction through optical fibers may be used. Furthermore, since the amount of the ultraviolet-generating substance depends on the amount of ultraviolet light, the amount of light may be increased or decreased as necessary.

The adsorption base material, which has been adsorbed and retained at a low temperature in advance, is placed together with the packaged food in a packaging bag made of, for example, an ultraviolet ray-permeable and gas-impermeable plastic abrasive material. Seal with packaging equipment. Thereafter, the adsorption base material is irradiated with ultraviolet rays. Depending on the food, UV irradiation may cause discoloration or deterioration in quality, which may be undesirable. Other uses include UV protection coatings. Inside the package, there is air between the adsorption base material and the space that adsorbs and holds the food and the UV-generating substance, and as the temperature of the adsorption base material rises, the UV-generating substance begins to be released and mixes in the air. Effectively suppresses microorganisms. This release is due to the adsorption properties of the adsorption base material, and the lower the temperature, the larger the adsorbed amount, and as the temperature increases, the adsorbed amount decreases, so that it is gradually released as the temperature rises. Depending on the food, you may want to completely suppress microorganisms by releasing it into the atmosphere. In that case, store the package in a container, etc., and then make the pressure inside the container somewhat negative to remove the air inside the package. What is necessary is to release it all at once from the adsorption base material.

This is done in a vacuum box at position A. During the series of vacuum packaging processes, the inside of the vacuum box is constantly irradiated with ultraviolet rays, and from the moment the package is placed in the box, ultraviolet ray-generating substances are generated, and the microbial suppression effect can be seen. In general, a vacuum packaging bag is one in which a part of the bag is already sealed except for the loading port which is open. In the process, the pressure inside the vacuum box is then reduced to a predetermined pressure, which removes the air inside the package. At the same time, the ultraviolet-generating substance adsorbed and retained on the adsorption base material is released, filling the package. Then, the desired sterilizing and disinfecting effects are applied to this. Furthermore, after performing a depressurization operation and reaching a predetermined degree of vacuum, the f595 of the package is
