The present invention relates to a method for manufacturing fermented alpha rice flour, wherein the fermented alpha rice flour is manufactured using rice as a main raw material. The fermented alpha rice flour is manufactured by immersing rice in warm water with added malt and amylase, followed by fermentation and saccharification, thereby inducing the property variation of rice； pulverizing, steaming, and punching the saccharified rice to make a rice paste； putting the rice paste into a rice cake molding machine to be molded into rice cakes having a predetermined shape and length； refrigerating and dehumidifying the rice cakes through first drying； slice-cutting the rice cakes, which are solidified after the first drying procedure, into pounded rice cakes or rice cake pallets, followed by second drying and then pulverizing. The fermented alpha rice flour of the present invention can be deep without being hard or stiff during frying, and can maintain a crisp and smooth texture for a long time even after frying. The fermented alpha rice flour of the present invention can overcome inherent limits of existing uncooked rice flour and alpha rice flour and provide novel texture and flavor, thereby satisfying new needs of consumers. Furthermore, the fermented alpha rice flour of the present invention can be used as a raw material of various cold and frozen processed foods due to the property variation, such as refrigerating and freezing stability improvement, thereby promoting the consumption of rice that is excessively supplied in the current rice situation. Furthermore, free-mix products which use the fermented alpha rice flour of the present invention as a main ingredient or a sub-ingredient and are suitable for various food processing fields can be produced. Furthermore, the fermented alpha rice flour of the present invention is mixed with various powdered materials having functionality, flavors, and colors and then steaming the mixture during the manufacturing procedur
