Abstract

The purpose. To determine and justify methods which ensure protection of grain at storage, for manufacture integrally net produce without application of any chemically aggressive substances. Methods. Analysis of known non-conventional methods of protection of grain during storage: thermal disinfection, treatment by microwave field, ozonation, control gaseous medium, laser bombarding radiation. Own researches in storage of grain of corn in conditions of modified gaseous medium. Results. Features of different methods of protection of grain and parameters of modified gaseous medium which ensure long-term resistant storage of corn depending on its temperature and damp are probed. Thermal disinfection is an efficient method in technique of storage of grain for struggle against warehouse pests. Treatment by microwave field is disinfection of grain from microorganisms which during the vital activity produce poisonous substances. Ozonation is physical and chemical method of disinfection of grain. Time of biological longevity of different crops on indexes of their vital activity is specified. Conclusions. Method of storage of grain of corn in the modified gaseous medium with the following parameters is offered: O2 (content of oxygen) — 4–5%, W (damp of grain) — 10–12%, t (temperature of grain) — 3–10°C. Other methods are unstable and their efficiency depend on state of bulk grain.
