FIELD: agriculture and food-processing industry. SUBSTANCE: method involves treating grain with propionic acid comprising chitosan additive in ultra-high frequency electromagnetic field; using specific preparation as chitosan source for adding to propionic acid, said preparation being produced by sequential extracting of Mortierella sepedonioides 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: reliable storage of grain. 2 ex |
