Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は無菌充填機に適用する食品容器の殺菌方法に
関する。Description: TECHNICAL FIELD The present invention relates to a method for sterilizing food containers applied to an aseptic filling machine.

〔従来の技術〕[Conventional technology]

無菌充填における容器の殺菌は大変重要であり、容器
の殺菌方法として、過酢酸による長時間浸漬殺菌法ある
いは過酸化水素の噴霧による殺菌法などが使用されてい
る。Sterilization of a container in aseptic filling is very important, and as a sterilization method of the container, a long-time immersion sterilization method using peracetic acid or a sterilization method by spraying hydrogen peroxide is used.

従来の過酢酸による容器の殺菌法は、100〜600ppmと
低濃度の過酢酸を容器中に充填し、０〜40℃の温度で長
時間保持した後滅菌水により洗浄するなどの方法がとら
れている。しかし、この方法は殺菌完了までに長時間を
要する等の問題がある。Conventional methods of disinfecting containers with peracetic acid include filling the containers with peracetic acid at a low concentration of 100 to 600 ppm, keeping them at a temperature of 0 to 40 ° C. for a long time, and then washing them with sterilized water. ing. However, this method has a problem that it takes a long time to complete sterilization.

又、従来の過酸化水素の噴霧殺菌方法は短時間省スペ
ースであるが容器の過酸化水素残留が問題となる。この
ため、この不具合に対し高濃度の過酸化水素水を噴霧後
乾燥またはリンスして処理するが、プラスチック容器の
表層中に浸透し、乾燥またはリンスのみでは完全な除去
が困難であった。Further, the conventional hydrogen peroxide spray sterilization method saves space for a short time, but has a problem of residual hydrogen peroxide in a container. For this reason, a high-concentration hydrogen peroxide solution is sprayed and dried or rinsed to treat this problem, but it penetrates into the surface layer of the plastic container, and it is difficult to completely remove it only by drying or rinsing.

〔発明が解決しようとする課題〕[Problems to be solved by the invention]

上述したように、従来の過酢酸による殺菌は多量の薬
液を使用することと殺菌に長時間を要するためインライ
ンで食品を高速充填する場合、装置が大きくなるなどの
不具合があり、又、過酸化水素噴霧殺菌は高濃度（35wt
％）過酸化水素が容器（樹脂）内部に浸透し徐々に析出
した飲料を汚染するという不具合があった。As described above, conventional sterilization with peracetic acid requires a large amount of chemical solution and requires a long time for sterilization.Therefore, when filling foods at high speed in-line, there are problems such as an increase in size of the apparatus, and peroxidation. Hydrogen spray sterilization has high concentration (35wt
%) There was a problem that hydrogen peroxide permeated into the inside of the container (resin) and gradually contaminated the precipitated beverage.

本発明は上記技術水準に鑑み、短時間で効果的な殺菌
が行え、かつ殺菌剤の残留もない食品容器類の殺菌方法
を提供しようとするものである。The present invention has been made in view of the above technical level, and aims to provide a method for sterilizing food containers that can perform effective sterilization in a short time and has no residual sterilizing agent.

〔課題を解決するための手段〕[Means for solving the problem]

本発明は過酢酸濃度1,000〜10,000ppm、液温100℃以
上の過酢酸水溶液を食品容器類に噴霧することを特徴と
する食品容器類の殺菌方法である。The present invention is a method for sterilizing food containers, which comprises spraying an aqueous solution of peracetic acid having a peracetic acid concentration of 1,000 to 10,000 ppm and a liquid temperature of 100 ° C. or higher onto the food containers.

すなわち、本発明は噴霧殺菌を行なうための殺菌剤と
して過酸化水素のように残留しない過酢酸溶液を用い、
かつ、液量を少なくし短時間殺菌ができるように濃度を
高くして、加熱噴霧して殺菌するようにしたものであ
る。That is, the present invention uses a peracetic acid solution that does not remain like hydrogen peroxide as a disinfectant for performing spray disinfection,
In addition, the concentration is increased so that the amount of liquid is reduced and sterilization can be performed in a short time, and sterilization is performed by heating and spraying.

〔作用〕[Action]

1.過酢酸の濃度、温度を高くすることにより殺菌時間が
大幅に短縮される。1. The sterilization time is greatly reduced by increasing the concentration and temperature of peracetic acid.

2.過酢酸のミストを容器表面に均一に薄膜状に付着させ
ることにより従来の浸漬法と同等の殺菌効果が十分あ
る。2. By applying the peracetic acid mist uniformly on the surface of the container in the form of a thin film, the sterilization effect equivalent to the conventional immersion method is sufficient.

〔実施例〕〔Example〕

過酢酸による噴霧殺菌テストを1.5lPETボトルを用い
てつぎのような条件で実施した。The spray sterilization test with peracetic acid was carried out using a 1.5 l PET bottle under the following conditions.

１）供試ボトル:PETボトルに106個／cm2付着 ２）指標菌：バチルス サブティリス｛Bacillus Subti
lis（ATCC6633）｝芽胞 ３）過酢酸噴霧：噴霧量0.16g/s、噴霧温度100℃ ４）乾燥：温度80℃、風速100m/s ５）リンス：無菌水 以上のような条件で殺菌テストを実施した結果を表
１、表２に示す。1) test bottle: 10 6 to PET bottles / cm 2 attached 2) indicator bacteria: Bacillus subtilis {Bacillus Subti
lis (ATCC6633)｝ Spores 3) Peracetic acid spray: spray amount 0.16g / s, spray temperature 100 ° C 4) Drying: temperature 80 ° C, wind speed 100m / s 5) Rinse: sterile water Perform sterilization test under the above conditions The results obtained are shown in Tables 1 and 2.

過酢酸殺菌と過酸化水素殺菌との残留量の比較を表
３、表４に示す。 Tables 3 and 4 show a comparison of the residual amounts between peracetic acid sterilization and hydrogen peroxide sterilization.

過酢酸殺菌では噴霧濃度が低いため残留は認められな
いが、過酸化水素殺菌ではPETボトル（1.5l）内に２〜3
ppmの過酸化水素が残留することとなる。 In the case of peracetic acid sterilization, no residue is observed due to the low spray concentration, but in the case of hydrogen peroxide sterilization, 2-3
ppm of hydrogen peroxide will remain.

〔比較例〕(Comparative example)

従来法の、液温20℃で所定濃度の過酢酸水溶液を充填
したときの殺菌効果の結果を表５に示す。表５にみられ
るように、従来法では殺菌に長時間を必要とする。Table 5 shows the results of the bactericidal effect of the conventional method when a predetermined concentration of peracetic acid aqueous solution was filled at a liquid temperature of 20 ° C. As seen in Table 5, the conventional method requires a long time for sterilization.

〔発明の効果〕 本発明方法により、短時間で効果的な殺菌が可能とな
り、しかも殺菌剤の残留がなくなった。 [Effects of the Invention] According to the method of the present invention, effective sterilization can be performed in a short time, and further, there is no residual fungicide.
