The invention discloses a processing method of nutrient rice. The processing method comprises the following steps that 1, rice screening is conducted through adopting a drum primary cleaning sieve anda vibrating screen; 2, impurities are removed; 3, solutions are mixed. The water, edible alkali, carrageenan, protease k and sodium citrate are uniformly mixed, and the mixture is heated to 60-70 DEGC for later usage; 4, soaking is conducted, the rice with the impurities removed in 2 is put into the 60-70 DEG C solution obtained in 3 and the soaking lasts for 20-40 minutes; 5, drying is conducted; 6, the rice is shelled; 7, the husked rice separation machine is adopted for separating the husked rice from the unhulled rice; 8, rice milling is conducted, the husked rice with the water contentof 18% is subjected to roughening and whitening by adopting a rice milling machine; 9, the rice cooling is conducted, the rice obtained in 8 after roughening and whitening is placed in a cooling ricebin to stand for 24 hours; 10, polishing is conducted; and 11, packaging into bags is conducted. According to the method, the flavor and the nutritive value of the nutrient rice can be improved.
