Scientists have found a method to clean packaged meat from dangerous bacteria using radiation UrFU has developed a method to clean already packaged meat from pathogens with radiation 12:30

Experts from the Ural Federal University (UrFU) have created a method to disinfect chicken meat from dangerous bacteria. The method is a irradiated surface treatment that is an effective way to kill Pseudomonas aeruginosa, salmonella, and other pathogens that may be present in chicken meat. The Ministry of Education and Science of the Russian Federation told socialbites.ca about this.

“Treatment of chicken meat with ionizing radiation is effective because contamination (infection) is reduced by more than half. At the same time, the shelf life of the product increases – for example, chilled meat is stored for about seven days, but after processing, the shelf life increases to a month. This is a big plus not only for consumers, but also for companies that produce chicken meat; because extending shelf life makes it possible to increase logistics leverage and transport products to remote and hard-to-reach markets such as China.” A senior researcher at the department told socialbites.ca about the experimental physics of UrFU Ruslan Vazirov.

Traditional methods of processing chicken meat in meat processing plants usually involve chemical, heat or thermal treatments. These methods, unlike ionizing radiation, can reduce the nutritional value of the product or change its physicochemical composition. It is also possible to process already packaged products using ionizing radiation, which cannot be done by conventional methods.

The radiation process occurs under the influence of electron beams – a flow of electrons moving in one direction. Electron beams are generated using a special installation – nanosecond accelerators URT-1 and URT-0.5, developed at the Institute of Electrophysics of the Ural Branch of the Russian Academy of Sciences. URT-1 can perform treatment with different doses of radiation depending on the settings.

“When most consumers hear the word “radiation,” they think of Chernobyl and think it’s necessarily a bad thing. However, radiation therapy is an effective method to protect food from pathogenic microorganisms, especially since approximately 30% of all food produced in the world is lost due to spoilage, including microorganisms,” Vazirov concluded.
