The invention discloses a method for preparing a high-color-value red rice product based on solid state fermentation and relates to a solid state fermentation media component and a preparation method thereof capable of remarkably improving the pigment yield of sorghum pigment monascus T3 (Monascus kaoliang T3). The main fermentation substrate in the solid state fermentation media component is red rice, meanwhile, a small amount of fructose (0.1%-1.0%), ammonium chloride (0.01%-0.45%), magnesium sulfate (0.05%-0.5%) and monopotassium phosphate (0.1%-0.5%) are added, 0.01%-0.1% (w/v) of lactic acid-aqueous solution is adopted to control the initial moisture content of the medium to be 25-55%, and then the solid state fermentation media of the sorghum pigment monascus T3 (Monascus kaoliang T3) can be obtained after sterilization. In the process of preparing high-color-value red rice, sorghum pigment monascus T3(Monascus kaoliang T3) spore suspension is inoculated to the cooled solid state fermentation medium for cultivation, and finally, the high-color-value red rice product is obtained after fermentation products are dried.
