PURPOSE: A production method of iron-reinforcing grains is provided to supply enough iron, and not to change the intrinsic shape of grains. CONSTITUTION: 1-5% of soluble starch is dissolved in cold water, and coating liquid in a colloid state is produced by boiling the water for 5-10 minutes. Grains and iron powder, which are washed and prepared, are inserted into a compressed-pill maker, and are mixed by rotating for 1-3 minutes in 10-100 rpm of speed. The soluble starch coating liquid is inserted into the compressed-pill maker, and mixed by additionally rotating for 1-3 minutes. The grains in which iron are reinforced is dried for 30-200 minutes at 70 deg. C.
