The advantage of aluminium foil bag packaging is that other traditional packaging materials do not have, as packaging materials, packaging also plays a very important role, its speed is faster than other traditional packaging materials development, use it for many aspects of life, so the use of a wide range of aluminium foil bag packaging aseptic treatment when we how, Jinan plastic bag under the small knitting with you. Share:
Aluminum foil bag is the main cause of secondary contamination of aseptic products. Traditional chemical or physical disinfection methods can damage the quality of packaging materials. The temperature of microwave disinfection is lower than that of conventional heating disinfection, which has little effect on the quality of products. In the sterilization and sterilization technology of plastic packaging bags, mainly for sealed aluminium foil bags. Because this kind of sterilization is carried out after the commodity packaging sterilization, generally do not use chemical methods. These sterilization technologies mainly include:
1. Heat charge sterilization
这是一种将食品或饮料加热至80 ~ 90℃，热成热箔袋，密封，贮存在高温或一定温度下杀菌的方法。该处理方法主要用于酸性液体食品。
This is a method of heating food or beverage to 80 - 90 C, heating foil bags, sealing, storage at high temperature or a certain temperature sterilization. The treatment method is mainly used for acidic liquid food.
2. Sterilized cooking
The method is mainly used in some foods with low acidity, such as meat, fish, poultry, milk, eggs, etc. Sterilization temperature is generally 121 C or 134 C. The method is to put the aluminium foil bag (cooking bag) into a high pressure sealed container and heat it with steam or pressurized water. According to the different conditions of sterilization bag, it can be divided into static heating sterilization and rotary heating sterilization. High pressure sterilization can be divided into saturated steam sterilization, air pressurized steam sterilization and pressurized water sterilization according to different heating media. At present, saturated steam sterilization is widely used because of its reasonable cost and convenient humidity control.
3. Ultraviolet sterilization
After packaging food or beverage, aluminum foil bags can also be disinfected by high-efficiency ultraviolet radiation. When using this method, the intensity and time of ultraviolet radiation are determined according to the size and content of the package.
