PROBLEM TO BE SOLVED: To provide a method for producing a calcium preparation capable of being used as a pharmaceutical or nutritive preparation free from protein residues and fat residues by using animal bones such as fish bones as a raw material. SOLUTION: This method for producing calcium preparation comprises applying operations such as a grinding operation and a waterwashing operation to animal bones preliminarily subjected to a large meat piece-removing treatment, adding an enzyme for decomposing organic materials to the treated animal bones, if necessary, further inoculating one or more kinds of microorganisms selected from bacteria, yeasts and molds in the treated animal bones, aerating and stirring the liquid, simultaneously heating the liquid to decompose the organic materials, washing the treated bones with water, drying the bones, and further repeating the operations once or more. Therein, the obtained animal bone powder is treated with the aqueous solution or dispersion of an amphoteric surfactant and further treated with an oxidizing agent. |
