PURPOSE:To obtain a finely pulverized rice flour, by dipping unpolished rice and polished rice in water or hot water, freezing the dipped unpolished rice and polished rice, vacuum drying the frozen rice, and pulverizing the vacuum dried rice. CONSTITUTION:Unpolished rice or polished rice is dipped in water or hot water to adjust the water content to about 20-30%, and the resultant dipped rice is then quickly frozen, dried under about 0.2-0.01mm.Hg reduced pressure and then pulverized. As a result, finely pulverized rice flour which could not be obtained in the past can be obtained. The fine powdery rice flour is particularly suitable for compositions used in a culture medium.
