Production manner of the unpolished rice powder, comminution the raw materials unpolished rice which is dried with dry process and the said dry process which dry the raw materials unpolished rice which the moist heat treatment is done

摘要

PROBLEM TO BE SOLVED: To modify a starch so as hardly to be gelatinized in a proper range and to modify the starch so as to reduce the viscosity of a gelatinized solution in a proper range even if the starch is gelatinized. SOLUTION: In this method for producing unpolished rice flour comprising a wet- heat treatment process for subjecting raw material unpolished rice as it is to a wet-heat treatment, a drying process for drying the raw material unpolished rice subjected to the wet-heat treatment by the wet-heat treatment process and a flouring process for flouring the raw material unpolished rice dried by the drying process to give unpolished rice flour, the wet-heat treatment is carried out so that at least two of (1) a relative peak intensity in a diffraction peak 3b (angle of diffraction 2θ is 15 deg) derived from the starch is 0.012-0.023, (2) a relative peak intensity in a diffraction peak 4a-4b (angle of diffraction 2 θ is 17-18 deg) is 0.030-0.070 and (3) a relative peak intensity in a diffraction peak 6a (angle of diffraction 2θ is 23 deg) is 0.030-0.060 are exhibited when a relative peak intensity of X-ray diffraction is measured by an X-ray diffraction apparatus under a fixed condition.
