O3 Greentech Applications – Food Safety


In the current scenario, we are using chemicals like Hydrogen Peroxide, Chlorine compounds, Caustic Soda to wash fruits and disinfect them and solve other problems like:

  • Incomplete disinfection
  • Undesirable tastes and odours
  • Toxic compound formation
  • Unwanted residue in food
  • High amount of water in cleaning

Apart from chemicals, there are other methods like physical methods and irradiation. However, while they may produce some satisfactory results, but they may harm the nutritional value of the food item.

For this, we introduce Ozone as a one-stop solution for a safer and healthier option.

Why Ozone in the Food Industry?

The numbers say it all.
But to put it in words, Ozone is the best option in the Food industry for:

  • Protection against micro-organisms, pesticide residue and post-harvest preservation agents
  • Enhanced post-harvest preservation as against the chemicals being used currently
  • Odour removal


Role of Ozone in the Food Industry

  • Clean in Place
  • Open Production Area Washing and Cleaning
  • Machines and Apparatus Cleaning
  • Hand Washing


How Does Gaseous Ozone Aid the Food and Beverage Industry?

Beverage Industry
Ozone is used for:
  • Purifying the water used in production
  • Clean-In-Place System
  • Cleaning bottle in bottle washers
  • General cleaning

Dairy Industry
Ozonated water is used to:
  • Feed cows
  • Clean and sterilise milking equipment
Gaseous ozone is used to:
  • Reduce the odours in the barn
  • Control the growth of yeast and mould
  • Treat waste-water

Fish, Poultry and Meat Processing
Ozone is used for:
  • Prepare ice and reduce pungent odour of fish
  • Preservation agent in egg and meat storage (gaseous form)
  • Pre-rinsing to reduce initial biomass of microbes (ozonated water)

Agricultural Products Export
Ozone is used to preserve the quality of the following products when they are exported:
  • Tea
  • Coffee
  • Desiccated Coconut
  • Spices
