A new milling method was contrived to prepare intact starch granules from the outer layer of rice grains. the grains were first soaked in 0-100% ethanol and then wet milled. As the enthanol concentration increased, the solvent content of soaked grains decreased, and the hardness of the grains increased; both showed an inflection point at an ethanol concentration of 60%. It was proved satisfactory to soak and mill rice grains in 60-70% ethanol, based on the milling degree, milling breakage, and the properties of the starch granules prepared. This method is useful as a laboratory technique.
