PURPOSE:To provide an industrially usable and simple method for obtaining essences of fishes, shellfishes or algae containing effective peptides, etc., corresponding to uses such as medicines, various functional foods, drugs, various growth agents, feed additives for domestic animals, seasonings, etc., and further a large quantity of mineral components included in the resources. CONSTITUTION:This method for extracting essences of fishes, shellfishes or algae having a large quantity of mineral components is to carry out proteolysis of fishes, shellfishes or algae by a protease, purify and separate an extract and waste. The proteolysis is carried out by applying an acid resistant protease at <pH5.0. to elute the mineral components into the essence. By this method the mineral components included in fishes, shellfishes and algae resources can be eluted into the essence solely by changing pH within a specific range during the usual proteolysis. |
