How does it work?
|Primary objective||Microbial decontamination of surfaces|
|Working principle|| Peroxyacetic acid (brand name Persteril) is suitable for decontamination of a wide range of microorganisms, viruses (HIV, TBC, bird flu), moulds and spores (e.g. TBC, Antrax). Peroxyacetic acid breaks down quickly into oxygen and acetic acid with the latter quickly vaporizing through the packaging. It works by oxidation like chlorine based sanitizer. It is a very suitable disinfection agent usable in agriculture, food industry and medicine. The most suitable forms of application are circulating, spraying, rinsing, immersion, spraying aerosols, evaporation, etc. [1, 2, 3, 4, 5].|
|Additional effects||environment friendly|
|Important process parameters||concentration, contact time, temperature, pH|
|Important product parameters||concentration|
What can it be used for?
|Products||These technologies can be used for decontamination of a wide range of food products (e.g. vegetables).|
|Operations||Sanitizing and decontamination|
|Solutions for short comings||These technologies can replace chlorine based agent.|
What can it NOT be used for?
|Products||Any material where acetic acid and hydrogen dioxide be harmful (e.g. metals including iron, magnesium and zinc, forming hydrogen gas and salts called acetates).|
|Other limitations||A disadvantage is the loss of effectiveness in the presence of some metals and high organic loads. Sanitizer can corrode the surface of some metals. EPA determined that the products containing peroxyacetic acid could be used safely and effectively, and that no unreasonable adverse effects would occur from the requested uses.|
|Risks or hazards||Concentrated peroxyacetic acid has a strong pungent smell. At some concentrations 1,500 to 2,500 ppm it has been shown to be cytotoxic.|
|Maturity||Peroxyacetic acid are generally used for decontamination in food industry|
|Modularity /Implementation||This technology can be easily implemented to existing production line.|
|Consumer aspects||Consumers do not like chemical preservation. This conservative is quickly changed after application into acetic acid or hydrogen dioxide that releases quickly from the target.|
|Environmental aspects||They are very efficient and friendly to environment.|
