Antimicrobial Effects of Ozonated Water Against Generic E.coli on Swine Intestines Varying Ozone Concentrations and Exposure Times
Abstract:
Swine intestines harvested then turned inside-out and washed with cold water to remove all visible contaminants were tested to have a generic E.coli load of 6 to 7.5 logs per gram of tissue. Samples of these tissues were treated with ozonated water at various concentrations for various lengths of time up to a total of 30 seconds. It was determined that concentrations below 1 ppm had no significant anti-E.coli effects at any of the exposure times tested. At 1 ppm and above significant kills were achieved with a 1 second exposure time. At 1 ppm and up to 2.5 ppm a 15 second exposure time was needed to achieve the greatest E.coli kill, and at 3 ppm and above a 1 second exposure time was all that was needed to achieve the greatest E-coli kill.

This paper is very exciting as it shows the concentration of ozone in water and the contact time necessary to achieve E.coli reduction. This papers shows that 2.0 ppm of dissolved ozone for only 1 second of contact time achieves a 3 log reduction of E.coli bacteria. This new data is extremely useful in understanding the effectiveness of ozone use in spray applications where contact time is very short.

Ozone has been used in the flour milling industry for various uses for many years now. Dissolved Ozone has been used in the wheat tempering process, and gaseous ozone has been used in the flour for microbe control. Recently Ozone Solutions was involved in using ozone for shelf life extension of the Bran product.
For this application ozone gas was introduced into bran agitators to lower bacteria, yeast, and mold counts. Ozone Solutions provided an Ozone Generator within a NEMA 4 enclosure to be used for this process. Two sealed bran agitators were used to mix the ozone with the bran product.
Bran Agitators used to mix bran and inject ozone into bran
This pictures shows the bran agitators that were used. The ozone was injected into two ports on top of the mixer on the far end of the picture. The wall mount ozone generator that was producing the ozone necessary for this process is seen in the background.

This system has recently become operational. Testing and lab data will be obtained over the next few months.

Did you know that the fruits and vegetables in your refrigerator have likely been treated with ozone? Ozone kills bacteria which makes your food last at least twice as long and up to four times longer than the normal shelf life. With the Fridgezone GH-2138 you can do what the Food Industry has been doing for years… in your very own fridge!
Put the Fridgezone in your fridge and let run and see the results in a few days!
