Zusammenfassung:	The invention discloses a method for removing tannin in roxburgh rose juice by using protein. The method comprises the following steps: extracting the protein; and removing the tannin from the roxburgh rose. After the ginger oil is extracted by using a supercritical CO2 extraction technology, ginger protein extracted from ginger residues reacts with tannin in the roxburgh rose juice to form a precipitate, and the tannin is separated and removed, so that the taste of the roxburgh rose juice is improved, a clarification effect is achieved, and the appearance is improved. According to the roxburgh rose juice and the preparation method thereof, tannin is removed as much as possible, VC is reserved as much as possible, so that the roxburgh rose juice has relatively high nutritional value, the tannin removal rate and the VC retention rate are high, the transparency of the roxburgh rose juice is high, ginger protein and a tannin compound precipitate part are separated, and high comprehensive utilization efficiency o
