Peracetic acid is an organic compound used as an eco-friendly sanitizer, disinfectant, or sterilizer in the food industry where food safety can be compromised by microbial contamination. It has a better germicidal response than hypochlorite and can inactivate Gram negative bacteria although is less effective against Gram positive bacteria. Nevertheless, PAA is a colorless liguid that is an effective antimicrobial agent used in processing poultry, meat, seafood, eggs & is certified as an organic produce wash. Food processors find that ~80 ppm of PAA works well when the sanitizer is in direct contact with the food item.
For sanitizing food processing equipment hard surfaces, higher concentrations, up to 500 ppm, may be required in beverage plants, breweries, wineries and restaurants. Medical supplies and equipment such as endoscopes may need even higher concentrations, in the range of 3000ppm.
As a biocidal oxidizer it is largely unaffected by organic matter and generates fewer toxic byproducts (potential mutagens) compared with chlorine disinfectants. This in turn makes it ideal for municipal wastewater treatment and maintaining drinking water needed for human consumption. Its range of application is broad spectrum where it finds use in water tower treatment & the pulp industries as a paper bleaching agent or to prevent biofilm formation. Peracetic acid is relatively unaffected by water hardness and can be diluted with regular tap water.
Testing for PAA can be done with different methods. The most convenient and economical are test strips. Other analytical methods such as spectrophotometry or electrochemical sensors are required for quantitative measurements.
Peracetic acid's versatility is often determined by contact time as well as concentration. Choose the right test strip for the job.
See Safety/Instructions for necessary precautions.
Note: All test strips Made in the USA & are Q/A'd against NIST standards.
Test Strip Expiration Dates; Good Today, Dead Tomorrow? Don't toss good test strips away. Good today doesn't mean bad tomorrow.
Diluting Chlorine, Hydrogen Peroxide, Quats, Peracetic Acid is Easy. Understanding metric makes it very easy to dilute disinfectant to any ppm whether spray bottles or backpack sprayers.
Peracetic acid oxidizes the membranes of microorganisms by electron transfer. The higher the EV potential, the faster this transfer occurs and the faster the microbe is inactivated.
Follow the directions on the label. All Indigo® peracetic test strips are "quick response". Dip the strip & compare to the color chart within 10 seconds. Peracetic acid's effective pH range is reduced as it increases from a neutral 7 to slightly alkaline levels between 8 & 9.
EPA Acute Exposure Guideline Levels indicate peroxyacetic acid can be corrosive/irritating to eyes, mucous membranes and skin after exposure to concentrations as low as 5 ppm for only 3 min. Wearing PPE is recommended especially when handling concentrates or where ventilation is poor.
Peracetic acid is an equilibrium with hydrogen peroxide & acetic acid. It eventually breaks down into water, oxygen and carbon dioxide.
