This chapter introduces different processes and methods for the milling of rice flour, and outlines the effects of these different methods on the properties of rice flour products. Physicochemical properties, such as chemical compositions, nutritional properties and thermal properties of different rice flour are summarized. Rice flours are often modified using a range of methods to change such product characteristics as water absorption index (WAI), water solubility index (WSI), sediment volume andin vitrodigestibility. These modification methods, which include extrusion, fermentation and hydrothermal treatment, are discussed and their effects on the properties of rice flour are summarized.
