PURPOSE:To obtain the titled pharmaceutical useful for a calcium nutrient supplement for liquid food due to the ready dispersibility, by expanding a food material consisting of calcium salt powder, starchy material and protein in an extruder while heating and pressurizing, and pulverizing the resultant expanded material. CONSTITUTION:A food material consisting essentially of calcium salt powder, starchy material and/or protein is first heated and pressurized preferably at 120-160 deg.C in an extruder, extruded into the air and expanded. The resultant expanded material is then pulverized to give preferably 100-500mu particle diameter. Thus, the aimed pharmaceutical 2 containing the calcium salt powder 3 and the above-mentioned porous food material 4 as constituent components is obtained. |
