Preparation method of oyster peptide powder grease

The invention discloses a preparation method of oyster peptide powder grease. The preparation method comprises the following steps: (1) pre-treating oysters; (2) performing enzymolysis on oyster tissue homogenate with protease to obtain an inactivated enzymolysis oyster peptide material liquid; (3) separating and purifying the oyster enzymatic hydrolysate, obtaining an oyster grease protein compound and a hydrolyzed oyster protein peptide material liquid after separation, and discarding oyster tissues which are not subjected to enzymolysis; and filtering the hydrolyzed oyster protein peptide material liquid to obtain a hydrolyzed oyster protein peptide filtrate, and concentrating the hydrolyzed oyster protein peptide filtrate to obtain an oyster protein peptide concentrate; (4) preparing an enzymolysis liquid, namely uniformly mixing the oyster protein peptide concentrate, the oyster grease protein compound, an embedding base material, an emulsifier and an antioxidant in proportion toobtain an enzymolysis oys
