PROBLEM TO BE SOLVED: To produce a seasoning extract having excellent taste and flavor by treating the back bone and remaining bone of fish with a protease thereby effectively utilizing the back bone of fish such as salmon holding a considerable amount of remaining meat attached to the bone owing to the difficulty in complete meat collection or utilizing the remaining bone left after collecting remaining meat from the back bone. SOLUTION: The back bone and/or remaining bone of fish such as salmon are subjected to endoprotease treatment and the endoprotease reaction is continued by adding the back bone and/or remaining bone of fish. The above endoprotease treatment process is repeated once or more and the product is treated with exoprotease to obtain the objective seasoning extract. The bone is separated into individual bone pieces after the endoprotease treatment and the bone piece free from the marrow meat at the center of the bone is separated and removed. |
