Adding trypsin and flavourzyme for double enzymolysis, and centrifuging to obtain filtrate; decolorizing and deodorizing the filtrate; filtering and drying to obtain giant salamander liver peptide powder; the giant salamander liver peptide powder is added into 12-55-degree base liquor according to the mass ratio of the giant salamander liver peptide powder to the base liquor being (1-1.5): 100, and the giant salamander liver peptide liquor improves the activity of ethanol dehydrogenase and acetaldehyde dehydrogenase in the liver, promotes decomposition of ethanol and acetaldehyde, improves the activity of SOD and GSH-Px enzymes in the liver, inhibits the activity of glutamic-pyruvic transaminase and glutamic oxalacetic transaminase, reduces the MAD content in liver tissue, and improves the liver health. The effects of dispelling the effects of alcohol and protecting the liver are achieved during drinking.
