Zusammenfassung:	PROBLEM TO BE SOLVED: To achieve sterilization/disinfection of food materials such as cereal grains, vegetables and fruits only by performing short-time processing without using a substance harmful to a human body, prevent mold from being generated, and enable long-term preservation of the food materials.SOLUTION: After food materials are caused to contact superheated steam of a temperature of 250-620°C, calcium oxide-containing powder that contains calcium oxide is added to the food materials, and then the food materials are mixed. It does not matter if the calcium oxide-containing powder is added to the food materials and the food materials are mixed as soon as the food materials are caused to contact superheated steam. The superheated steam contact time is preferably 0.5-20 seconds. The calcium oxide-containing powder is preferably natural calcium oxide (calcinated calcium) powder acquired by calcinating a shell, coral, nacreous layer, egg-shell or bone of a beast, fish, or bird at high temperature.
