Abstract

PURPOSE: To obtain a digestible and highly nutritious food, by heating grain under pressure so that it is gelatinized, reducing quickly the pressure to normal pressure so that it is expanded, cutting it in lengths, making it flat before hardening, followed by drying.

CONSTITUTION: Grain such as unpolished rice, wheat, adlay, or beans, alone or their mixture is heated under pressure so that starch is gelatinized, the grain is extruded from a nozzle to an atmospheric pressure, so it is expanded and immediately cut. In cutting, the speed of a rotary cutter is adjusted to make the diameter and length of the expanded matter approximately equal, so the cut expanded matter is made almost spherical. The cut expanded matter is rolled before it is hardened, made flat to give thin small disks, which are dried to give a product. Since the starch is gelatinized, the product has good taste and not raw scent when used directly for food. Since the product is frothy, it is easily soluble in water and warm water, so it can be used for food like a common food by simple cooking.
