The invention relates to a preparation method of an
oyster protein beverage, and the method comprises the following steps: cleaning fresh
oyster meat, removing black edges and internal organs, homogenizing, then adding water, adding an
enzyme for enzymolysis so as to get
oyster enzymatic
hydrolysate, performing deodorization and decolorization treatment on the oyster enzymatic
hydrolysate, adding a beverage compound
browning inhibitor and a beverage
emulsion stabilizer, stirring, uniformly mixing, heating, performing high-pressure homogenization, performing vacuum degassing, then sterilizing, canning, cooling to
room temperature and then storing at the temperature of 4 DEG C. The oyster
protein beverage has a variety of physiological health care functions; the preparation method is simple, convenient and fast, and deodorization and decolorization effects are obvious; and the problem that the color and luster of the oyster
protein beverage are darkened during the storage period is controlled so as to keep the color and luster of the oyster protein drink stable and be in line with the drink standard.
