PURPOSE: A processing method of brown rice is provided to remove a paraffin wax layer on the surface of the brown rice with a rice hull extract, and to enable users to easily cook and digest brown rice. CONSTITUTION: All dust and small fragments are removed from rice hulls using a wind blower to assort the rice hulls, and the rice hulls are sterilized (S100). The sterilized rice hulls are mixed with boiling water at a temperature greater than 100°C, and the mixture is boiled for extracting (S101). The obtained rice hull extract is cooled down to a temperature lower than 50°C (S102). The cooled rice hull extract and brown rice are mixed at a weight ratio of 1:1, and the mixture is rotated to remove a paraffin wax layer on the surface of the brown rice by friction (S103). The brown rice without the paraffin wax layer is separated from the mixture, and dried (S104). The mixture without the brown rice is boiled into a temperature greater than 100°C for filtering (S105).
