PURPOSE: Disclosed is a method for producing a powder nutritional supplement using eels or conger eels as a raw material by enabling the removal of a bone marrow liquid from the bones of the eels or the like. CONSTITUTION: This method for producing a powder nutritional supplement using eels or conger eels as a raw material comprises subjecting bones taken out the eels or the like to the primary washing treatment, a mincing treatment, the secondary washing treatment, and so on, to form rice-like bone grains b, draining the bone grains b, charging the drained bone grains into a retort bag, subjecting the bone grains to a high pressure. high temperature treatment process(5a) at 70 to 180°C at 1.5 to 4 atm to remove the bone marrow liquid from the bone grains, further subjecting the left bone grains to the tertiary washing treatment(5b), a hot air-drying process(6) and a pulverizing process(7) to form the powder d, and finally subjecting the powder d to a sterilizing and deodorizing process(8) comprising irradiating 1.5 to 1,500 μm IR light for a prescribed time to prepare the powdery nutritional supplement suitable for drinking.
