PURPOSE:To obtain a packed raw rice cake preservable for a long period at normal temperature, by steaming glutinous rice, making it into a rice cake in a sterilized atmosphere, packing it individually into a packing material having low permeability to oxygen gas, and packing collectively it and a disoxidant into a packing material having low permeability to oxygen. CONSTITUTION:Glutinous rice having a small number of total molds is selected, steamed in such a way that <10 total molds exist based on 1g, it is made into a rice cake in a sterilized atmosphere such as clean room, etc., molded, cooled, and cut. The prepared cut rice cake is irradiated by ultraviolet rays to sterilize the surface of the rice cake, packed individually into a sterilized packing material having 50-2,000cc/m .24hr.atm oxygen permeability to make <10% oxygen concentration. Then, the packed rice cake and a disoxidant are successively packed into a packing material having <50cc/m .24hr.atm oxygen permeability collectively, to give a packed rice cake preservable for several months at normal temperature.
