The invention discloses the preparation method of a seed oyster selenium-enriched protein powder, the preparation method includes：Oyster living is placed 10 15 days in the yeast selenium seawater containing 0.1 0.25% mass fraction；Oyster living is won into oyster meat, the internal organ of oyster meat are cleaned up, then by oyster meat and deionized water by weight 10:10 50, it blends at a high speed, obtains oyster liquid and add protease weight ratio 100 into oyster liquid:0.5 1, it is that 30 50MPa stir 12 hours under conditions of temperature is 40 50 DEG C, Oyster Protein enzymolysis liquid is obtained by filtration in pressure；After Oyster Protein enzymolysis liquid enzyme deactivation, the oyster selenium rich of egg white powder is obtained by freeze-drying；The present invention prepares selenium rich of egg white powder using oyster as raw material, Zn content highest wherein in oyster, and Se content is relatively low, therefore the present invention adds yeast selenium culture 10 15 days by using oyster living, increases the content of selenoprotein in oyster. |
