OZONE RESEARCH

Produce Research

Ozone may stop bacteria on produce better than food irradiation or washing.

Ozone can replace traditional sanitizing agents such as chlorine and provide other benefits in the washing, sanitizing, and storage of produce.

Basics of Ozone Applications for Postharvest Treatment of Vegetables

Ozone has been evaluated for postharvest disease control and other storage uses for many years. Commercial use includes apples, cherries, carrots, onions, and potatoes.

Seafood Research

The Use of Ozone as a Disinfectant in Fish Hatcheries and Fish Farms

An ideal method of disinfecting water is by ozonation in a contact tank prior to use. Ozone is a very powerful bactericide and viricide and, unlike other agents, it leaves no undesirable residues. The latest available advanced ozone technology, which will enhance efficiency, now lies within the reach of all operators.

Researchers Find New Use for Ozone for Seafood

In a study supported by the North Carolina Fishery Resource Grant Program (FRG), scientists found that ozone reduces the population of common spoilage bacteria in seafood processing facilities.

Ozone Better Than Chlorine In Catfish Processing

Ozone, the unstable form of oxygen created by lightning bolts during a thunderstorm, also has the capacity to be harnessed in making catfish processing plants cleaner and in doubling the shelf life of catfish.

Ozonated Water on Knife Dips, Hard Surface Sanitation and Meat Cuts

The goal of this analysis was to determine the effectiveness of ozonated water as a hard surface sanitizer, knife dip sanitizer, and microbial reducer on meat cuts.

Wastewater Research

Wastewater Reduction and Recycling in Food Processing Operations

The food processing industry seeks cost-effective reduction and recycling technologies for food processing wastewaters. These technologies include both source reduction options and treatment options.

Ozone in BOD Treatment and as Flocculating Agent

This study was conducted at a Fortune 500 poultry processing plant. The results of this study showed a reduction in total phosphates by 14%. Additionally, ozone was able to flocculate the suspended solids allowing them to be removed by a carbon filter.

Ozonation of Swine Manure Wastes

The results of this study demonstrate clearly that at the pH values studied, ozonation is effective for the elimination of the malodors associated with stored swine slurry and for killing potentially pathogenic bacteria, without increasing the concentrations of major pollutants of current concern, and without oxidizing ammonia, which is a major plant nutrient.

Applications of Ozonation and Membrane Treatment in Poultry Processing

Included in this study are techniques to reuse chiller water for poultry processing as well as the benefits of using ozone.
