The present invention relates to a method for preparing aseptic packaged instant wet scorched rice, which mixes roasted rice, polished rice, and dried scorched rice, sterilizes the mixture, and adds a concentrate extracted from roasted rice, a polygonatum concentrate, and rice cooking water with a rice starch to the mixture to produce wet scorched rice. Subsequently, the thus-produced wet scorched rice is sealed in an aseptic condition, steamed, and cooled to produce aseptic packaged instant wet scorched rice. As the aseptic packaged instant wet scorched rice prepared according to the method of the present invention is sterilized, the rice can be preserved over 6 months or longer at room temperature. Further, the flavor of the roasted rice and the scorched rice is diffused to maximize the unique flavor of the scorched rice. The starch of the scorched rice is eluted to the rice cooking water to provide a predetermined turbidity and to enrich the flavor of the scorched rice. The scorched rice of the present invention is well softened, and has the unique texture of scorched rice. Therefore, the scorched rice of the present invention has a superior quality rivaling that of homemade scorched rice, and can be preserved over a long period of time.
