Production method of scallop skirt fermentation product with blood pressure reduction function

The invention discloses a preparation method of a scallop skirt fermentation product with a blood pressure reduction function. The preparation method includes the following steps: cleaning scallop skirts, removing impurities and draining prior to freeze-drying and grinding to obtain scallop skirt freeze-dried powder; mixing scallop skirt freeze-dried powder with water and sucrose prior to regulating the initial pH value; performing sterilization, adding bacillus natto bacterial suspension, and performing ventilated culture to obtain scallop skirt fermentation liquor; performing centrifugation, collecting supernate, and performing concentration and freeze-drying to obtain the scallop skirt fermentation product with the blood pressure reduction function. The scallop skirts are fermented via bacillus natto, enzymes with a thrombolytic function can be produced, proteins in the scallop skirts are further degraded into proteins and polypeptides smaller in molecular weight, and digestive absorption is facilitated; f
