The purpose of this study was to investigate the physicochemical and processing properties of commercial rice flour (CF). Rice flours of Chenmaai and Goamibyeo were compared to CF. Amylose, protein, lipid, and ash contents of CF were lower than those of two rice varieties. CF was suitable for a raw material for the bread baking, but the problem was fast retrogradation rate. Cooking loss of cooked noodle of CF was too high and textural properties were not appropriate for eating. With the technology development for milling to reduce damaged starch and lower water absorption of flour, selecting the high amylose rice cultivars will help to produce the commercial rice flour which is more suitable for bread baking.
