FIELD: agriculture.
SUBSTANCE: according to the proposed method the grain substrate is poured into gas-permeable polyethylene bags and kept at a temperature of 55°C and humidity of 57% within 30 minutes. Then the bags with the substrate are kept in the gas mixture, which is consists of 10-20% of ethylene oxide and 80-90% of carbon dioxide. At that the bags with the substrate are kept under pressure 0.5-0.8 bar at a temperature of 55°C and humidity 57% during 45-90 minutes.
EFFECT: proposed method provides acceleration of the process of obtaining a sterile grain substrate and improvement of efficiency of disinfection while reducing costs.
