<p>PURPOSE:To produce economically refined SAKE, etc. of high quality, by heating rice flour under pressure, releasing the heated rice flour rapidly to a region under ordinary pressure, charging the resultant puffed rice flour by the conventional method, and brewing the charged puffed rice flour. CONSTITUTION:Rice flour heat-treated at 190-200 deg.C for within 20sec under 2- 6kg/cm<2> pressure is released rapidly to a region under ordinary pressure and expanded to destroy proteins or tissue, etc., reduce lipid and produce the aimed puffed rice flour easily digestible by enzymes. The resultant puffed rice flour (preferably subjected to the contraction treatment) as a main raw material is brewed by the conventional method to produce refined SAKE, low-class distilled spirit, etc. Rice bran formed as a by-product in polishing rice for producing polished rice for brewing refined SAKE (about 50% polished rice yield) may be used in place of the above-mentioned rice flour.</p> |
