Morphological capillary-porous structure analysis of the oilseed materials, using x-ray microtomography in the longitudinal and transverse section and FESEM analysis of the surface microstructure after electrical and microwave treatment presented in current paper. Experimental data were obtained on the basis of the Institute of Materials Research and Engineering (Singapore). Two types of treatment considered: non-thermal pulsed electric field treatment, creating an electroporation effect of the oilseeds structure and microwave treatment. The main characteristic of capillary-porous structure of oil-bearing materials is given. Local changes in the electron density of the oilseed object under study, during the passage of radiation, made it possible to determine clearly the air cavities in the structure of the sunflower nucleus. The influence of a pulsed electric field treatment on the integrity of the structure of oil-cell membranes has been obtained with the creation of a material that has a greater permeability for diffusion processes. Experimentally was determined that over 2500 electric pores were formed on an area of 1 sq.cm as a result of a pulsed electric field treatment. In the case of a pulsed electric field treatment, the oil body material model can be represented as a capillary model with capillary and electroporation radii, thus expanding the model of a bidispersed structure with the addition micro capillaries, formed by an electric field. The data obtained are of interest not only for the technology of processing oilseeds, but also for the analysis methods of new electrophysical treatments.
