PURPOSE: To prepare a roast rice which has excellent taste and flavor, and can be softened in a short time, by using glutinous rice with hull harvested early after 20W25 days from heading.

CONSTITUTION: Glutinous rice with hull harvested early, i.e. 20W25 days after heading for early maturing variety or 20W27 days for late maturing variety is immersed in water at about 25°C for 24hr to effect the sufficient absorption of water. The rice is then drained, steamed and parched. After cooling the parched rice, it is treated with a husker to separate the glutinous rice grain from the hull. The rice is polished, removed from the hull by a winnower, and the polishing and winnowing procedures are repeated at least twice. The obtained glutinous rice is rolled with a rolling machine, and quenched quickly with a large amount of chilled air.
