鋁箔袋包裝如何做好無(wú)菌處理?

來(lái)源:http://58gaofang.com/ 日期:2023-09-18

鋁箔袋是造成后產(chǎn)品二次污染的一個(gè)主要原因,常規(guī)的化學(xué)或物理方法損害包裝物的品質(zhì),微波比常規(guī)加熱所需溫度低、對(duì)產(chǎn)品質(zhì)員不會(huì)造成很大影響。就塑料包裝袋殺技術(shù)而言,主要是針對(duì)密封的鋁箔袋。因?yàn)檫@種殺是在物品包裝好后的殺,一般不采用化學(xué)方法。這些殺技術(shù)主要有下列幾種:

Aluminum foil bags are a major cause of secondary contamination of products after sterilization. Conventional chemical or physical disinfection methods damage the quality of packaging materials. Microwave disinfection requires lower temperatures than conventional heating disinfection and does not have a significant impact on product quality. In terms of plastic packaging bag sterilization technology, it mainly targets sealed aluminum foil bags. Because this type of sterilization is carried out after the item is packaged, and chemical methods are generally not used. These sterilization technologies mainly include the following:
1、熱裝法
1. Hot pack sterilization method
這是一種將加熱80~90℃的食品或飲料,趁熱裝入熱的鋁箔袋中,進(jìn)行密封后,在高溫或一定溫度下貯存的方法。這種處理方法主要用于酸性大的液態(tài)食品。
This is a sterilization method of heating food or beverages to 80-90 ° C, placing them in hot aluminum foil bags while they are hot, sealing them, and storing them at high or certain temperatures. This treatment method is mainly used for liquid foods with high acidity.

2、蒸煮法
2. Steaming sterilization method
這種方法主要用于一些酸性較小的食品,如肉、魚、家禽、牛奶、雞蛋等。溫度一般為121℃或134℃。采用的方法是將鋁箔袋(蒸煮袋)放人高壓密閉容器內(nèi)用蒸汽或加壓水加熱。根據(jù)蒸煮袋在時(shí)的不同情況可分靜置加熱與回轉(zhuǎn)加熱等。 加壓高溫根據(jù)采用的加熱介質(zhì)不同,又可分飽和蒸汽、空氣加壓蒸汽以及加壓水等。目前用的較廣的為飽和蒸汽,因?yàn)樵摲绞劫M(fèi)用經(jīng)濟(jì)合理,濕度控制方便。
This method is mainly used for some less acidic foods, such as meat, fish, poultry, milk, eggs, etc. The sterilization temperature is generally 121 ℃ or 134 ℃. The method used is to place the aluminum foil bag (steaming bag) into a high-pressure sealed container and heat it with steam or pressurized water. According to the different sterilization conditions of steaming bags, they can be divided into static heating sterilization and rotary heating sterilization. Pressurized high-temperature sterilization can be divided into saturated steam sterilization, air pressurized steam sterilization, and pressurized water sterilization according to the different heating media used. The currently widely used method is saturated steam sterilization, as it is cost-effective and convenient for humidity control.
3、紫外線
3. UV sterilization
鋁箔袋包裝食品或飲料后也可以通過紫外光線的照射達(dá)到的目的。在采用該法時(shí),要視包裝袋大小、內(nèi)容物的多少,而確定紫外線的照射強(qiáng)度和時(shí)間。
After packaging food or beverages in aluminum foil bags, sterilization can also be achieved through efficient ultraviolet light irradiation. When using this method, the intensity and duration of ultraviolet radiation should be determined based on the size of the packaging bag and the amount of content.
