Peracetic Acid Disinfectant-Sanitizer Test Strips

Peracetic acid (PAA) is a powerful oxidizing agent widely used as a disinfectant and sanitizer. It offers broad-spectrum antimicrobial activity while breaking down into harmless byproducts—acetic acid, oxygen, and water—making it suitable for food processing, healthcare, and water treatment.

These test strips provide a quick and reliable way to measure PAA concentrations directly at the point of use. They eliminate the need for meters or reagents and give accurate results within seconds, ensuring compliance with sanitation protocols.

Indigo® PAA test strips are available in multiple concentration ranges to fit specific applications, from routine surface sanitation to higher-strength solutions used in wastewater treatment.

Choose the Right Indigo® PAA Test Strip

Different applications require different PAA concentrations. Use this guide to select the most suitable strip for your industry or process.

Range Best Use Cases Notes
0–50 ppm (residual) Produce wash water, beverage rinse lines, food-contact surface residual checks Designed to ensure low residual levels and compliance on finished surfaces.
0–160 ppm Beverage tanks, bottling lines, general sanitation in food & beverage plants Good balance between sensitivity and range for routine plant sanitizing.
0–1000 ppm Heavy-duty sanitizing, produce/processing equipment, CIP systems with organic load For situations where peracetic acid is used in higher working concentrations.
0–3000 ppm High-level sterilization, medical device reprocessing, industrial/wastewater disinfection Intended for very high concentration checks; ensure proper PPE and dilution procedures.

Advantages & Disadvantages

Like any disinfectant, peracetic acid has strengths and trade-offs. Knowing these helps you choose the right test strip and application:

  • Advantages: Rapid antimicrobial action; effective against bacteria, fungi, and spores; environmentally friendly breakdown products (vinegar, water, oxygen); leaves no harmful residue.
  • Disadvantages: Unstable in storage and solution; corrosive at high concentrations; pungent odor; performance depends on pH and temperature.

PAA Test Strip Common Features

All Indigo® peracetic acid test strips share the following features to ensure reliable results across industries:

  • Fast color development with clear, stable endpoints
  • Accurate within the stated ppm ranges
  • Long shelf life under recommended storage conditions
  • Economical for routine monitoring
  • Relevant to EPA, FDA, and USDA/FSIS regulatory compliance
  • Indigo® PAA test strips are Made in the USA & Q/A'd against NIST standards.

Chemical Properties of Peracetic Acid

Peracetic acid compound disinfectant chemical structure

Peracetic acid (C2H3O3) is a powerful oxidizing agent approved by the US EPA for use in food processing, healthcare sanitation, and wastewater treatment.

 

Peracetic acid is a simple but highly reactive organic peroxide with the following key properties:

  • Formula: C2H4O3
  • IUPAC Name: Ethaneperoxoic acid
  • CAS Number: 79-21-0
  • Synonyms: Peroxyacetic acid, acetic peroxide, acetyl hydroperoxide
  • Equilibrium: Exists in balance with hydrogen peroxide (H2O2) and acetic acid (CH3COOH)
  • Melting Point: ~0 °C
  • Boiling Point: ~105 °C
  • Applications: EPA-approved for food processing, healthcare sanitation, and wastewater treatment

 

Practical Notes

  • Expiration Dating: All Indigo test strips are printed with a guaranteed 3 year expiration from date of manufacture, providing a clear shelf-life reference and ensuring reliable performance.
  • Storage: Store strips in a cool, dry place away from direct sunlight and volatile chemicals to maintain accuracy.

Instructions/Safety

How to Use:

  • Dip the test strip into the sample solution.
  • Remove after the specified time (typically a few seconds).
  • Compare the color pad to the provided chart.
  • Record and act on results according to your operating procedures.

Safety Considerations:

  • PAA is corrosive; wear gloves and eye protection when handling concentrated solutions.
  • Avoid inhaling vapors; use in a well-ventilated area.
  • Store strips away from direct sunlight, heat, and moisture.

Regulatory Notes:

  • PAA is recognized by the EPA as a sanitizer and disinfectant.
  • FSIS permits its use in poultry and meat processing.
  • FDA allows its use in food contact surface sanitation under specified conditions.
