  • Patent number: 6149796
    Abstract: A method of manufacturing an aqueous solution of biocompounds containing peptide as a major component and a hydroxyapatite containing minerals and being useful an inorganic or organic composite material from tissue in an electrolytic cell by performing the electrolysis of an aqueous solution of the tissue and by taking advantage of an electrode reaction using suitable electrodes. In this case, a DC current is passed between the electrodes in the aqueous solution, thereby dissolving and crystallizing the tissue components. After unreacted matters are removed, the resultant mixed solution is separated into solid matters and a liquid. The aqueous solution of biocompounds is obtained from the filtrate, and the hydroxyapatite is obtained from the recrystallized solid matters.
