PURPOSE: A process of preparing the titled calcium supplementing agent by mixing an eggshell with an edible dispersing agent, a precipitation preventing agent and distilled water and grinding is provided. Whereby, the agent does not change a taste, smell and color and generates coagulation, precipitation or the like when used for calcium-enriched food. CONSTITUTION: A dispersing agent, a precipitation preventing agent and distilled water are added to a powdery eggshell having a particle size of 8 to 15 microns and the obtained mixed solution is introduced into a bead mill having a bead of 0.3mm or less and wet-ground to give a mixed solution having a d50 value of 0.2 microns or less and d90 value of 0.4 microns respectively. The mixed solution comprises 10.0 to 70.0% by weight of calcium from Eggshell, 0.1 to 10.0% by weight of methylcellulose, 0.1 to 10.0% by weight of poly-solvate and distilled water. The dispersing agent is selected from methylcellulose, gelatin or gum arabic.
