Ozone for cold storage
In cold rooms, ozone disinfects the air and surfaces, holds back bacteria, mould and yeast, and neutralises odours, so stored food keeps its quality for longer.
The problem
Microbes, mould and odours build up in cold rooms over time, on walls, ceilings and equipment, and on the food itself.
That shortens shelf life and raises the risk of contamination in the food supply chain.
How ozone helps
Ozone lowers the microbial load in cold-storage air and on food surfaces, stopping bacteria, mould and yeast from growing. It also disinfects packaging materials, so contaminants do not reach the stored goods.
Ozone breaks down naturally into oxygen after use and leaves no hazardous chemical residue, which suits sustainable food-storage practice.

Questions
Cold storage: common questions
What kinds of food does ozone help preserve?
Perishables such as fruit, vegetables and meat, by holding back the bacteria, mould and yeast that cause spoilage.
Can ozone treat packaging too?
Yes. Packaging materials can be disinfected with ozone to stop contaminants reaching the stored contents.
Does it leave a residue on food?
No. Ozone breaks down into oxygen after use and does not leave hazardous chemical residues.
