容物が酸素に触れることのない、より保存性の高いレト
ルト殺菌方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a retort sterilization method, and more particularly to a retort sterilization method that does not allow the contents to come into contact with oxygen and has a higher preservability.
（従来の技術とその問題点）
内容物を収納密封した包装体を高温高圧の蒸気雰囲気下
で殺菌するレトルト殺菌処理方法は周知であり、食品や
医薬品、医療機器等に広く用いられている。(Prior Art and its Problems) A retort sterilization method in which a sealed package containing contents is sterilized in a high-temperature, high-pressure steam atmosphere is well known and is widely used for foods, pharmaceuticals, medical devices, and the like.
この方法に供される包装材料は一般にアルミラム箔を含
む積層材料であり、もし仮にこれを含まず、プラスチッ
クのみから成る包装材料を用いると、殺菌の高温高圧に
より酸素の分子運動が活発な上、包装材料の結晶構造も
くずれて酸素が透過し易くなるため、包装体内部に酸素
が侵入することが知られている。The packaging material used in this method is generally a laminated material containing aluminum foil. If a packaging material made only of plastic without aluminum foil is used, the high temperature and high pressure of sterilization will cause active oxygen molecular movement. It is known that the crystal structure of the packaging material also collapses, making it easier for oxygen to permeate, resulting in oxygen penetrating into the interior of the packaging.
しかるに、内容物によっては、アルミニウム箔を用いる
ための包装材料のコストアップを嫌ったり、内容物の透
視を可能とすることを望むものが数多くある。しかし、
これらは内容物によっては、酸化による油脂劣化、味覚
劣化等の品質の低下が生じる為、レトルト殺菌処理を施
し難いのが実情である。However, depending on the contents, there are many cases where the use of aluminum foil does not increase the cost of packaging materials, or where it is desirable to be able to see through the contents. but,
The reality is that it is difficult to retort sterilize these products because, depending on the contents, quality deterioration may occur, such as deterioration of fats and oils due to oxidation and deterioration of taste.
（問題点を解決するための手段）
この問題点を解決するため、本発明は、内容物を収納密

高圧下で殺菌することを特徴とするレトルト殺菌処理方
法を提供する。(Means for Solving the Problem) In order to solve this problem, the present invention provides that after storing the sealed package containing the contents in a closed system, the air in this system is replaced with an inert gas. The present invention provides a retort sterilization method characterized in that high temperature steam is then introduced and sterilization is carried out under high temperature and high pressure.
（作 用）
上述のように殺菌時には酸素が包装体内に侵入し易くな
るが、本発明によれば、包装体周囲に酸素がほとんど存
在していないので、酸素が侵入することが非常に少ない
。(Function) As mentioned above, during sterilization, oxygen tends to enter the package, but according to the present invention, since almost no oxygen exists around the package, oxygen intrusion is extremely rare.
（実施例の説明）
本発明に係る内容物は、殺菌時の熱に耐えるのであれば
任意のもので良いが、例えば食品、医薬品、等が好適で
ある。(Description of Examples) The contents according to the present invention may be of any type as long as they can withstand the heat during sterilization, but for example, foods, medicines, etc. are suitable.
また、本発明に係る包装材料は酸素バリヤー性の高いも

ク（ポリエチレンやポリプロピレン等）を積層したもの
が好適である。In addition, the packaging material according to the present invention is preferably one with high oxygen barrier properties, such as plastics with high oxygen barrier properties such as polyvinylidene chloride polyester, aluminum, ethylene-vinyl alcohol, and nylon, and other plastics (such as polyethylene and A laminated layer of polypropylene (polypropylene, etc.) is suitable.
包装材は袋の外、真空成型容器、射出成型容器等の形状
で用いることができる。内容物を収納密封する際には、
内部に酸素が残存することがないよう、真空包装するか
、窒素等の不活性ガスで空気を置換して包装することが
望ましい。The packaging material can be used in the form of outside bags, vacuum-formed containers, injection-molded containers, and the like. When storing and sealing the contents,
To prevent oxygen from remaining inside, it is preferable to package the package under vacuum or replace the air with an inert gas such as nitrogen.

内に収容され、この後、系内の空気を不活性ガスで置換
する。本発明における不活性ガスとは、内容物に接触し
てもとれに悪影響を与えることのないガスであり、卜述
した内容物に対しては窒素ガスが一般に不活性である。The sealed package containing the contents is placed in a sealed system such as a retort pot, and then the air in the system is replaced with an inert gas. The inert gas in the present invention is a gas that does not adversely affect the removal when it comes into contact with the contents, and nitrogen gas is generally inert to the above-mentioned contents.
内容物によっては、他の不活性ガスを用いることもでき
る。Other inert gases can also be used depending on the contents.
空気を不活性ガスで置換するには、系内を脱気し、不活
性ガスを導入して置換する方法の外、系内には水を満た
した後、不活性ガスを導入しながら排水することによっ
ても可能である。To replace air with inert gas, you can either evacuate the system and replace it by introducing inert gas, or fill the system with water and then drain it while introducing inert gas. It is also possible by
この後、高温高圧の水蒸気を導入する。水蒸気は１００
℃以上、１気圧以上のものが望ましく、例えば１２０〜
１４０°Ｃの飽和水蒸気である。After this, high temperature and high pressure steam is introduced. water vapor is 100
℃ or higher and 1 atm or higher is desirable, for example 120~
It is saturated steam at 140°C.
水蒸気の導入と同時に、系内の不活性ガスを排気又は導
入することにより、系内の圧力を調整する。Simultaneously with the introduction of water vapor, the pressure within the system is adjusted by exhausting or introducing an inert gas within the system.
圧力は１気圧以上である。The pressure is 1 atmosphere or more.
系内に水蒸気を満たした後、不活性ガスと水蒸気の導入
排出により系内の温度と圧力を予定された高温高圧状態
に一定時間保ち、加熱殺醒する。After filling the system with steam, the temperature and pressure in the system are maintained at a predetermined high temperature and high pressure state for a certain period of time by introducing and discharging inert gas and steam, and the system is killed by heating.
この後、不活性ガスの導入排出により圧力調整−ろ −
しながら、冷却水を導入して系内を冷却し、十分冷却し
てから、系を開放排水して系内を大気圧に戻す。Thereafter, while adjusting the pressure by introducing and discharging inert gas, cooling water is introduced to cool the inside of the system, and after sufficiently cooling, the system is opened and drained to return the inside of the system to atmospheric pressure.

Even a package using a packaging material consisting of only sterilization can be effectively sterilized without the influence of oxygen on the contents. For this reason, the present invention is suitable for cases where it is desired to see through the contents,
It is suitable for contents that are easily oxidized and for which it is desired to reduce the cost of packaging materials.
