Cold Chain and Ozone Application in Food Safety

The food supply chain is of great importance in ensuring the freshness and safety of products on their journey from farm to table. The recent increase in food poisoning complaints has once again shown that disruptions in any link of this chain can lead to serious health problems. You can access the related news from Hürriyet here. We unfortunately anticipated that this problem could arise with the summer heat, and in our blog post titled "Food Safety and Ozone", which we published earlier in the summer, we discussed ozone's applications and advantages in this field in detail. In this week's blog post, we wanted to emphasize the critical importance of improving cold chain practices and disinfection methods in order to minimize these risks. At OCS OZON, with our expertise in this field, we develop projects tailored to the needs of your business and offer next-generation solutions for consumer health and food safety.

The Role of the Cold Chain and Ozone Applications

The cold chain is a process that ensures food is stored and transported at a specific temperature from the moment of harvest until it reaches the consumer. This process is vital, especially for perishable foods, in order to slow microbial growth and preserve product quality. However, low temperature alone does not ensure the complete elimination of microorganisms. This is where ozone applications come into play.

Ozone gas, thanks to its powerful oxidative properties, effectively destroys pathogens present on food surfaces and in the air. Ozone kills microorganisms by oxidizing their cell walls, thereby reducing the microbial load of food. In addition, ozone's property of leaving no chemical residue makes it an ideal disinfectant in the food sector.

Ozone Applications in Cold Chain Processes

  1. Production and Harvest Stage: After food products are harvested, they can be washed with ozonated water in order to remove the microorganisms on their surfaces. This process preserves the freshness of the products while also reducing the microbial load.

  2. Storage and Transportation: The use of ozone gas in cold storage and during transportation destroys the microorganisms present in the air and on surfaces. Ozone can be applied across a wide range of different food groups, such as meat, fish, dairy products and vegetables. The use of low doses of ozone in storage areas extends the shelf life of products and prevents quality loss.

  3. Packaging: Ozone can also be used during packaging. By using ozone gas on the packaging line, contamination of the packaged products with microorganisms is minimized. This is even more effective, especially in techniques such as vacuum packaging and MAP (Modified Atmosphere Packaging).

  4. Retail and End User: In retail stores and supermarkets, ozonated air circulation extends the shelf life of products while also preventing the formation of bad odors. This provides a great advantage, especially for products such as meat and seafood that need to be kept odor-free.
