Claims (1)
1. The oyster peptide extracting process includes the following steps:
(1) Crushing: pulverizing cleaned and dried Concha Ostreae and Carnis Ostreae into Concha Ostreae fine powder;
(2) Dispersing: mixing oyster fine powder, calcium bicarbonate, sodium bicarbonate, microcrystalline cellulose and water, stirring, and dispersing uniformly to obtain a dispersion liquid; the input mass ratio of the oyster fine powder, the calcium bicarbonate, the sodium bicarbonate, the microcrystalline cellulose and the water is 1:0.03:0.05:0.02:25;
(3) Enzymolysis:
