紫外杀菌技术在瓶装水生产中的可行性分析

Feasibility Analysis of UV Sterilization Technology in Bottled Water Production

近年来,紫外杀菌技术被不断深入研究,并在食品物料、加工环境的杀菌中得以广泛应用。紫外杀菌具有操作简单、能耗低、没有消毒副产物、投资及维修费用低等优点,但从生产中的实际使用情况来看,该技术也存在着较大的微生物隐患。从杀菌机理、水源卫生、杀菌设备及参数、灌装环境等方面,对在无菌灌装线上利用此技术生产瓶装水做了相关的微生物风险分析。通过不同灌装条件下成品检测结果的对比,表明生产过程中对风险因素做好有效的管理和防控措施,在成品水中未检测出微生物,产品的质量安全可得到有效保障。

In recent years,UV sterilization technology has been intensively studied and widely used in the sterilization of food materials and processing environment. UV sterilization has the characteristics of simple operation,low energy consumption,no disinfection by-products,low investment and maintenance cost. However,the technology also has a larger microbial risk through the analysis of in-service situation. The risks associated with using this technique for bottled water production in aseptic filling line has been analyzed,including the disinfection principles,water quality,sterilization equipment and parameters,filling environment and other aspects. The detection results of finished product under different filling conditions indicated that the quality and safety of products could be well guaranteed. No living microorganisms would be existence in bottled water by implementing effective supervision and prevention measures in the process of manufacture.
