The coarse cereal composite rice comprises, by weight, 120-140 parts of corn, 40-50 parts of rice, 15-20 parts of oat, 3-5 parts of xanthan gum powder, 8-10 parts of laver, 4-6 parts of bean curd stick, 1-2 parts of garlic powder, 12-16 parts of freeze-dried strawberry powder, 4-6 parts of oyster powder, 2-4 parts of fish bone meal, 10-14 parts of buckwheat, 3-5 parts of camellia pollen, 6-8 parts of rhizoma drynariae and 7-10 parts of Achyranthes bidentata. Coarse cereals are puffed and milled, so the loss of nutritional elements is reduced, the fragrance is increased, and the nutritional elements can be easily absorbed by human bodies; mixed materials are steamed and granulated, so the material gelatinization degree is improved, thereby obtained composite rice granules have the advantages of very good boiling fastness, good molding effect and difficult cracking.
