PROCESS FOR PRODUCING DISSOLVED HARD TISSUES AND HARD TISSUES THUS DISSOLVED

WIPO Patent Application WO/1997/036911

A1

A process for producing dissolved hard tissues by dissolving a mixture of hard tissues and an acid such as lactic acid under the condition of, for example, reduced pressure and further dissolving the residue remaining in the solution with, for example, citric acid; and hard tissues thus dissolved, which contain organic substances including at least proteins, being present undenatured, and calcium. This process permits the hard tissues to be dissolved sufficiently in a short period of time without suffering from denaturation of the active ingredients peculiar thereto. The dissolved hard tissues are used as the active ingredients of foods, feeds, drugs, cosmetics, drinks, seasonings, toothpaste material, hair nourishing preparations, hair growth stimulant, or fertilizers.
