METHOD FOR PREPARING OF GRAIN FOR STORAGE Russian patent published in 2004 - IPC

FIELD: postharvest treatment of grain before laying for storage. SUBSTANCE: method involves treating grain with propionic acid comprising additives of chitosan, arachidonic acid and eicosapentaenic acid, until film is formed on surface of each corn seed; using source of chitosan, arachidonic acid and eicosapentaenic acid for adding into propionic acid, said source being preparation produced by sequential extracting of Mortierella spinosa micromycet biomass with the use of non-polar extractant in above-critical state, water, alkaline, water, acid, water, alkaline, and water, with following joining of first extract with solid residue. EFFECT: simplified process owing to the use of raw additive for introducing into propionic acid instead of pure substances.
