The new disinfection technology destroys bacteria on eggshells, including salmonella.She also
“Decontamination of packaged eggs protects eggs fromsubsequent contamination during storage, - explains Sergey Sokovnin, professor at the Ural Federal University and the Ural Branch of the Russian Academy of Sciences. - We have been able to create a method for disinfecting the container and eggshells that does not affect the physical properties of the protein, yolk and shells or their composition. And the size of the eggs doesn't matter. "
The irradiation experiments were carried out on the URT-0.5 accelerator. Credit: UrFU / Ilya Safarov.
86% of chicks from untreated eggs havesigns of chronic inflammation. In chickens from irradiated eggs, this figure reached only 4%. At the same time, the chickens from the second group had an increased immunity to Newcastle disease. This is a viral disease of birds. This means that chickens from sterilized eggs will be less sick. And it will be possible to significantly reduce the dose of antibiotics during the growth process.
This technology also saves time for industrialmanufacturers. It takes about six hours less to hatch chicks from clean eggs. Instead of the usual 22-24 hours, chicks hatch in 16-18 hours. This reduces manufacturing costs.
The technology allows irradiation of up to 40 eggs per second.The cost of disinfecting a plastic package of 10 eggs was 1.2 euro cents. If one technological line works in a shift of 250 working days a year, then the investment will pay off in five years. At the same time, the main costs are staff salaries, overhead costs and equipment costs.
Serious technical problems with implementationno technology. The small size of the accelerator makes it easy to integrate into existing egg control and packaging lines in poultry farms. The technology, according to scientists, can also be used to disinfect the surface of eggs of other birds and products with peels or other natural packaging (seeds, bananas, oranges).
