The use of radiaƟon technologies in agriculture and the food industry is a common worldwide trend. Global reducƟon of food products at all stages of producƟon
has reached 30%. Especially significant reducƟon is in fruits and vegetables producƟon. RadiaƟon treatment of food products helps to suppress the development
of pathogenic microorganisms as a result it extends the storage periods. Despite numerous studies in this field, exisƟng methods of irradiaƟon require opƟmizaƟon
in order to ensure the possibility of using irradiaƟon for all types of fruit and vegetable products. This research work is focused on the study of the effecƟveness
of irradiaƟon of model systems containing condiƟonally pathogenic microflora by electron beams with an energy of 6.5 and 10 MeV. Studies were conducted on
the effecƟveness of inhibiƟng the iniƟal degree of inoculaƟon of the microorganism E. coli. Solid and liquid nutrient media were used as the culture carrier in the
model systems. In this research work, a comparaƟve analysis of the effecƟveness of irradiaƟon of the same object at two radiaƟon installaƟons with different
power was performed. IrradiaƟon with doses up to 10 кGy was carried out at the FMI Center of the InsƟtute of Electrophysical Research of the Russian Academy
of Sciences and at the radiaƟon-technological facility at the A.I. Burnazyan Federal Medical Biophysical Centre of Federal Medical Biological Agency. The depen-
dences of inhibiƟon of pathogenic microflora, irradiaƟon with different intensity, on the structure (density) of the samples studied are revealed. The results of
effecƟve inhibiƟon of the iniƟal degree of seeding for two plants are obtained. It was detected that the effecƟveness of inhibiƟon of E. coli can vary depending on
the installaƟon. It is important to take into account not only the effecƟveness of the oppression of microflora on specific products, but also the efficiency of the
installaƟon for a specific sample.
Keywords: radiaƟon treatment, model systems, inhibiƟon of microorganisms, residual microflora, E. coli, raƟonal processing of raw materials.
