Perasan A
Perasan A is a high-potency, EPA-registered antimicrobial peracetic acid (PAA) sanitizer manufactured by Enviro Tech Chemical Services, an Arboris company. Formulated from an equilibrium mixture of peracetic acid, hydrogen peroxide, acetic acid, and proprietary stabilizers, Perasan A serves as an essential, no-rinse sanitizer across the commercial brewing, beverage bottling, meat processing, dairy production, and agricultural packaging industries. Delivering broad-spectrum biocidal efficacy against bacteria, yeasts, molds, and bacterial endospores without leaving toxic chemical residues, it is the benchmark for industrial food safety.
Chemical Composition, Equilibrium Chemistry, and Mode of Action
The chemical architecture of Perasan A is based on an equilibrium reaction between acetic acid (vinegar) and hydrogen peroxide, yielding an active peracetic acid (CH3COOOH) concentration of 5.6% to 6.0%, paired with 26.5% to 27.5% hydrogen peroxide. Peracetic acid is an exceptionally potent oxidizing agent with an oxidation-reduction potential (ORP) far superior to standard sodium hypochlorite (chlorine bleach) or chlorine dioxide.
The antimicrobial mode of action operates through the rapid oxidation and disruption of microbial cellular membranes. Peracetic acid penetrates microbial cell walls, denaturing protein sulfhydryl (-SH) and sulfur (S-S) bonds, halting enzymatic respiration, disrupting membrane transport proteins, and destroying intracellular RNA and DNA. Because this biochemical attack is purely physical oxidation rather than a single enzymatic pathway, microorganisms cannot develop genetic resistance to Perasan A.

| Environmental Decomposition | Breaks down to Acetic Acid, H2O, O2 | Zero toxic halogenated byproducts | Eco-friendly, drain-safe, non-polluting effluent |
The reaction rapidly eradicates pathogens in under sixty seconds.
Industrial Applications: Breweries, CIP Systems, and Food Contact
In the craft brewing, winemaking, and dairy processing sectors, Perasan A is the definitive chemical sanitizer for Clean-In-Place (CIP) closed-loop pipeline systems. After vessels are cleaned with alkaline caustic detergents (like sodium hydroxide), Perasan A is circulated as the terminal cold-water sanitizer across stainless steel fermentation tanks, bright beer tanks, plate heat exchangers, canning lines, and keg washing machines.
Under FDA 21 CFR 178.1010 regulations, Perasan A is approved as a no-rinse food contact surface sanitizer when diluted to concentrations between 1.0 and 2.4 fluid ounces per 6 gallons of water (yielding an active peracetic acid concentration of 82 to 197 ppm). Within this approved concentration window, surfaces do not require a subsequent sterile water rinse, eliminating the dangerous risk of re-contaminating sanitized stainless steel with municipal tap water bacteria.
Review dilution ratios, active PAA concentrations (ppm), and industrial sanitizing protocols for Perasan A:
| Sanitization Application | Dilution Ratio (Perasan A : Water) | Active PAA Concentration (ppm) | Required Contact Dwell Time |
|---|---|---|---|
| No-Rinse Food Contact Surface (CIP) | 1.0 to 2.4 fl oz per 6 Gallons Water | 82 to 197 ppm PAA | Minimum 60 Seconds wet contact |
| Non-Food Contact Surface Sanitizing | 1.0 to 3.0 fl oz per 5 Gallons Water | 115 to 345 ppm PAA | Minimum 5 Minutes wet contact |
| Fruit and Vegetable Wash Water | 0.5 to 1.5 fl oz per 10 Gallons Water | 25 to 75 ppm PAA | Continuous immersion / spray flume |
| Fogging in Food Processing Rooms | 2.0 fl oz per 10 Gallons Water | 100 ppm PAA | Evacuate room; fog until surfaces wet |
| Post-Harvest Water Disinfection | Dosed via proportional metering pump | 10 to 50 ppm PAA | Monitored with continuous PAA test strips |
Cold-water efficacy saves industrial plants massive thermal boiler heating costs.
Handling Safety, PPE, Test Strips, and Environmental Profile
In its concentrated stock drum form, Perasan A is a powerful, hazardous oxidizing chemical requiring strict Personal Protective Equipment (PPE) compliance. Concentrate splashes can cause irreversible eye damage, severe chemical skin burns, and respiratory irritation from pungent vinegar fumes. Plant operators must wear chemical-splash goggles, full face shields, neoprene chemical gloves, rubber aprons, and rubber boots when diluting concentrate.
To verify sanitizing strength on processing lines, sanitation managers utilize PAA chemical test strips or automated drop-count titration test kits. Verification ensures the solution meets the required 100 to 200 ppm PAA threshold. Environmentally, Perasan A is celebrated as one of the greenest sanitizers on earth: unlike chlorine which produces carcinogenic trihalomethanes (THMs), Perasan A rapidly biodegrades into harmless acetic acid (dilute vinegar), water, and oxygen, releasing clean effluent into municipal wastewater systems.
OMRI organic certification confirms its environmental safety profile.
How to Prepare and Apply a No-Rinse Perasan A Solution in 5 Steps
Follow these five certified food safety steps to dilute, test, and circulate Perasan A sanitizer.
Don Appropriate Protective Gear (PPE)
Put on chemical-splash goggles, neoprene gloves, and a rubber apron before handling the chemical drum.
Measure Clean Potable Cold Water
Fill the dedicated stainless steel CIP reservoir with 30 gallons of cool, clean water (ambient temperature below 85°F).
Add Perasan A Concentrate Accurately
Carefully pour 5 to 10 fluid ounces of Perasan A concentrate into the water, mixing gently to disperse.
Verify Active PAA with Test Strips
Dip a calibrated peracetic acid test strip into the solution, verifying color match between 100 and 200 ppm.
Circulate for 60 Seconds and Drain
Circulate through the pipeline or spray across tanks for a full 60 seconds; drain completely without rinsing.
