Abstract:
In the article, the possibility of using pulse-periodic electron accelerator SINUS-320 for sterilization of food products is
studied on the example of cocoa powder. The research was carried out by the method of statistical modelling using the
GEANT4 package. The results are presented in the form of dependence of the absorbed irradiation dose on the exposure depth.
The initial data for the study were the accelerating voltage (350 kV, 400 kV, 450 kV and 500 kV), the thickness of aluminium
anode foil (30 $\mu$m, 50 $\mu$m and 70 $\mu$m) and the thickness of the irradiated layer of cocoa powder (3 mm, 4 mm and 5 mm). The
results of the study showed that the use of the SINUS-320 generator allows effective sterilization of cocoa powder with a layer
thickness of 3-5 mm. This can be achieved through a combination of properly selected accelerating voltage and thickness of
the anode foil.
