The invention discloses a preparing method for coarse rice 
powder special for baking. The preparing method includes the following steps that (1) seasonablecoarse rice is selected, sterilized and cleaned, then is introduced into a 
cellulose solution under the humidification condition, and is subjected to micro 
germination treatment; (2) the obtained coarse rice is subjected to 
superheated steam treatment, and is cooled to the temperature of 40 DEG C to 45 DEG C after 
superheated steam treatment is completed, heat preservation is carried out, then the obtained coarse rice is added into a 
glutamine transaminase solution and soaked, and 
moisture is drained off; (3) the coarse rice after being drained off is subjected to 
microwave dryingtreatment; (4) the coarse rice after being subjected to 
microwave dryingtreatment is subjected to 
superfine grinding, and the coarse rice 
powder special for baking is obtained. According to the preparing method, the 
processing performance of the coarse ricepowder can be remarkably improved, the nutritive value of the coarse rice 
powder is improved, the problem that the taste of the coarse rice powder is coarse is solved, the baking 
processing adaptability of the coarse rice powder is improved, thedigestibility of the coarse rice powder is improved, the 
plasticity and the 
extensibility of the coarse rice powder are improved, the storage stability ofraw-material coarse rice powder is kept, and the coarse rice powder is suitable for production of bakery products such as biscuits, walnut cakes, cookies and cakes.
