실험 절차

Eggshell powder is used in the food industry, including animal and human nutritional supplements. Eggshells provide approximately 36-37 percent elemental calcium in addition to traces of phosphorous and other trace elements. Thus, for example, 500 mg of dried powdered eggshell provides approximately 180 mg elemental calcium. This compared vary favorably to other calcium salts. For example, calcium carbonate provides 40 percent elemental calcium, calcium citrate provides 21 percent elemental calcium, calcium lactate provides 13 percent elemental calcium, calcium gluconate provides 9 percent elemental calcium, dicalcium phosphate provides 23 percent elemental calcium (and 19 percent phosphorus), and bone meal provides 20 percent elemental calcium (and 17 percent phosphorus). A single large eggshell has a mass of approximately 6 g and provides approximately 2200 mg of calcium.
