Method for extending shelf life of germ remained rice by moderate moistening and electron beam irradiation

A method for extending shelf life of germ-remained rice, the method comprising:

• 1) evenly spreading the germ-remained rice on a sheet tray, and moderately moistening the germ-remained rice;
• and
• 2) packing the germ-remained moistened rice, and irradiating the germ-remained rice with an electron beam;
• and
• wherein moderately moistening comprises transferring the sheet tray to a constant climate chamber, and moistening the germ-remained rice at a temperature of 20-30° C. and a relative humidity of 88-99% for 1.0-2.0 hours without spraying water, until moisture seeps through the germ-remained rice;
• and
• the germ-remained rice is germ-remained indica rice or germ-remained japonica rice;
• the germ-remained indica rice is moistened to a moisture content of not more than 14.5%, and the germ-remained japonica rice is moistened to a moisture content of not more than 15.5%;
• and
• wherein the germ-remained rice moistened is irradiated with an electron beam at a dose of 0.5 to 1.0 kGy and stored at 25° C. from 75-120 days.
