Ozone washing for fruit and vegetables
Washing produce in ozonated water disinfects it without chemical residues, helps break down some pesticide residues, and extends shelf life by reducing spoilage microbes.
The problem
Fresh produce arrives carrying bacteria, viruses, spoilage microbes and pesticide residues.
Conventional chemical sanitisers can leave residues of their own behind.
How ozone helps
An ozone generator makes ozone on site, using an electrical discharge to turn oxygen (O₂) into ozone (O₃). Dissolved in the wash water, ozone oxidises microbes on the produce and in the water.
It also breaks down some pesticides and chemical residues on the surface of vegetables into simpler, less harmful molecules, and then reverts to harmless oxygen.
Benefits06
What changes with ozone
- 01
Fresher produce
Disinfection without chemical residue, for fresher, safer vegetables.
- 02
No chemical residues
Ozone breaks down into oxygen without producing hazardous by-products.
- 03
Better food hygiene
Effective disinfection of fruit and vegetables at the washing stage.
- 04
Longer shelf life
Lowering the microbial load on surfaces can extend shelf life.
- 05
Pesticide reduction
Helps break down and remove some pesticide and chemical residues.
- 06
Cleaning and disinfection
Eliminates bacteria, viruses and other pathogens on the surface.

Questions
Vegetable washing: common questions
Does ozone remove pesticides?
Ozone can break down and help remove some pesticide and chemical residues on the surface of produce, by oxidising them into simpler, less harmful molecules.
Does it leave anything on the vegetables?
No. Ozone breaks down into oxygen, leaving no chemical residue.
Will produce last longer?
Reducing the number of spoilage microbes on the surface and in the wash water can extend shelf life.
