Cell membranes of plant materials anatomical integrity changes under the influence of filamentary microplasma treatment assisted by thermionic emission

Abstract

The effect of low-temperature filamentary microplasma treatment on the anatomi-cal integrity of cell membranes of plant raw materials was studied. It is shown that microplasma treatment forms a through channels in the structure of plant materi-als and accelerate mass transfer process. The effect on the cell membrane of plant raw materials leads to a change in the capillary-porous structure with the for-mation of additional pores formed by microplasma discharge, oriented along the direction of the electric field strength. It was found that the dependence of the number of destroyed cells on the intensity of microplasma treatment is limited and decreases with longer processing of plant raw materials. According to the results of experimental studies, it was established that with microplasma treatment assis-tant, it is possible to control mass transfer processes which are important for the further processing of plant raw materials, such as drying and extraction
