Abstract: Raw material rice (brown rice and partially-milled rice) is subjected to a preliminary pressurized steam-boiling process to form an alpharized layer on the surface of the raw material rice, and then a moisture adding process is performed. Since the surface of the raw material rice is alpharized to become stiff with the preliminary pressurized steam-boiling process, even rapid moisture addition does not cause a crack in the raw material rice. Therefore, water absorption can be quickly achieved to a target moisture content, thereby reducing a moisture adding time. Also, with no crack, quick-cooking rice with an excellent outer appearance of rice as a product and without a drain of nutrients in rice grains at the time of rice cooking.

Abstract: Milled rice grains are primarily immersed, and at least surface layers of the grains are converted to the alpha-type. The rice grains are then preliminarily dried and consummatively polished, and are further subjected to secondary immersing and secondary alpha-type conversion. During these processes, there occurs no cracking on the surfaces of the rice grains. The consummatively polished rice grains are then separated into individual single grains. The separated individual single grains are finally dried whereby the finished product of instant rice is obtained. The instant rice containing polished rice has good appearance and quality.
