PROBLEM TO BE SOLVED: To provide a production method of freeze-dried fish powder, which can provide higher unsaturated fatty acids that are said good to bodies but are said ineffective to take as a supplement, and much contained in adult fishes, without reducing the higher unsaturated fatty acids by grilling or stewing fishes and further without discarding various nutrient components contained various sites such as head, bone, internal organ and so on.SOLUTION: Below a fish inhabitation temperature zone, a fish body is appropriately cut such that an internal organ containing a gill of a fist is divided, after that, a germicidal treatment is applied, then, after freeze-drying, each of cut parts is mashed by an ultrafine mill, followed by vacuum freeze-dried. Thus, including higher unsaturated fatty acids that the fish has, various kinds of nutrition components are maintained, when, without modifying, a safe and ease dry fish powder is provided, a waste residue called as fish waste can be prevented from occurring.SELECTED DRAWING: Figure 1
