Provided is a method for producing fermented blood sausage having high antioxidant activity, comprising (1) preparing hemoglobin antioxidant peptide through Plastein reaction; (2) brining and primarily fermenting livestock or poultry meat; (3) deodoring and breaking livestock or poultry blood; (4) filling and secondary fermentation; (5) obtaining a finished product after drying. Compared with prior arts, the present disclosure uses Plastein reaction of blood to prepare a highly active antioxidant peptide, the fermented blood sausage has a total antioxidant capacity up to 6.89 U/mg protein, with an increase rate of 58%. The blood was deodorized, and total amount of free amino acids in secondary fermentation by lactic acid bacteria in combination with yeasts reached 12.74 mg/g, with an increase rate of 42%, providing the fermented blood sausage with better flavor and chewiness. The present disclosure also provides a new approach to comprehensive utilization of livestock or poultry blood resources.
