The invention discloses a method for extracting a multifunctional nutrient of tuna blood mixed meat for longline fishing. The method comprises the following steps: crushing tuna blood mixed meat, extracting, heating and settling, performing enzymolysis, decoloring, concentrating, drying and the like. Water is used as a solvent to extract water-soluble functional substances such as goose carnosine, carnosine, taurine, organic selenium and the like. Compared with common direct enzymolysis, the functional substances can be enriched by 2-4 times through a specific water extraction process. The method does not need to add complex chemical reagents, has low requirements on extraction equipment, is simple and easy to operate, and is easy for large-scale production. The prepared tuna blood-mixed meat multifunctional nutrient is light in fishy smell, white in color and rich in various natural functional substances, certain reference value is provided for research of food, biological medicine and the like, and meanwhil
