Ozone Washing Science
Ozone (O₃) is one of the most powerful oxidants available for food disinfection – 30–50 times more effective than chlorine and 3,000 times faster at killing pathogens.
Here’s exactly how ozone washing makes your vegetables truly clean & safe:
Here’s exactly how ozone washing makes your vegetables truly clean & safe:
- How Ozone Kills Pathogens (The Science)
- Ozone is highly unstable and instantly breaks down into O₂ + a single oxygen atom [O]
- This free oxygen atom is extremely reactive and destroys bacteria, viruses, fungi, and pesticides by:
- Rupturing cell walls of bacteria (E. coli, Salmonella, Listeria etc.)
- Damaging viral capsids
- Breaking down fungal spores
- Kills 99.99% of common pathogens in 10–30 seconds (proven against E. coli, Salmonella, Listeria, Norovirus, Hepatitis A)
- Pesticide & Chemical Residue Removal (The Real Magic)
- Regular water washing removes only 10–20% of pesticide residues. Ozone washing removes 75–99% of common pesticides including:
- Chlorpyrifos → 98% removed
- Captan → 97% removed
- Carbendazim → 91% removed
- Malathion, DDT, Endosulfan → 80–95% removed

- Regular water washing removes only 10–20% of pesticide residues. Ozone washing removes 75–99% of common pesticides including:
- Why Ozone is Superior to Chlorine/Vinegar/Other Washes
| Parameter | Chlorine Wash | Vinegar/Baking Soda | Ozone Wash (Krishipure) |
|---|---|---|---|
| Pathogen kill rate | High | Very low | Extremely high (99.99%) |
| Pesticide removal | 20–40% | 10–30% | 75–99% |
| Leaves chemical residue | Yes (chlorine) | No | Zero residue |
| Affects taste/smell | Yes (bleachlike) | Yes (vinegar smell) | None |
| Approved by | FSSAI | FDA | FSSAI, FDA, USDA, EU Organic |
- 100% Safe – Zero Residue
- Ozone naturally decomposes into pure oxygen in 10–20 minutes
- No harmful byproducts
- Approved by FDA, USDA, FSSAI, and European Union as GRAS (Generally Recognized As Safe)
- Used in municipal drinking water treatment worldwide.
- Proven Results from Real Studies (India & Global)
- CFTRI Mysore (2022): Ozone washing reduced pesticide residue by 92–97% in spinach & tomatoes.
- IARI Delhi (2023): 99.7% reduction in microbial load on leafy greens
- Journal of Food Science (2021): Ozone extended shelf life of vegetables by 40–60%
