PROBLEM TO BE SOLVED: To provide a method for producing pregelatinized unpolished rice, in which the pregelatinized unpolished rice keeping the nutritive ingredients of unpolishd rice and having an excellent taste and excellent digestive absorbability even by the usual cooking method for polished rice is efficiently produced. SOLUTION: This method for producing the pregelatinized unpolished rice, characterized by comprising a water-absorbing process for allowing unpolished rice to absorb water, a drainage process for removing water adhered to the surface of the water-absorbed unpolished rice, a steaming process for directly bringing the drained unpolished rice into contact with high temperature steam, a high frequency wave heating process for irradiating the steamed unpolished rice with microwaves, and a drying process for drying the high frequency wave- heated unpolished rice. In the steaming process, the absorptive supply of the water to the unpolished rice and the rough pregelatinization of raw starch are carried out. In the high frequency wave heating process, the thermal denaturation of proteins, the perfect gelatinization of the starch, the scattering of fatty acids mainly causing the bad smell, and the evaporation of excessive water are performed. Consequently, the pregelatinized unpolished rice can be boiled by the same boiling method as that for polished rice to give the boiled unpolished rice having excellent taste and excellent absorbability without deteriorating the nutritive ingredients of the unpolished rice. Further, since the excessive water evaporates in the high frequency wave heating process, the drying time can be shortened. |
