PROBLEM TO BE SOLVED: To provide a processing method for long storage of cereals, to provide cereals processed to be storable for long, and to provide a processing apparatus for long storage of cereals. SOLUTION: The processing method includes bringing steam plasma into contact with cereals for a short time. The cereals are various cereals such as rice, wheat, bean, corn, and millet, and may be cereals which are unskinned, skinned, crushed, ground, granulated or scraped. The steam plasma has a temperature of 40-600°C, and the time to bring the steam plasma into contact with the cereals is preferably for 0.1-30 s. The steam plasma is generated by either one kind selected from the group consisting of dielectric barrier electrical discharge, corona electrical discharge, high frequency electrical discharge, and microwave electrical discharge.
