FIELD: agriculture. SUBSTANCE: method involves cleaning grain from contaminants; creating grain flow in the form of falling rain and providing aerosol flow of propionic acid comprising chitosan additive; directing aerosol flow of propionic acid through supersonic horn for contacting with grain flow; using specific preparation as chitosan source for adding to propionic acid, said preparation being produced by sequential extracting of Mortierella alliaceae micromycet biomass with the use of non-polar extractant in above-critical state, water, alkaline, water, acid, water, alkaline, and water, followed by joining of first extract with solid residue. EFFECT: increased efficiency and reliable storage of grain. 2 ex |
