The invention relates to a method for producing sea cucumber bio-alcohol. The method has the following characteristics that: sea cucumber is soaked in water, the produced soak is centrifugally filtered and concentrated, the produced concentrated solution is cooled, fucoidan hydrolytic enzyme is added to enzymatically hydrolyze the fucoidan in the concentrated solution, the temperature is increased to 80 DEG C to 90 DEG C, so that the fucoidan hydrolytic enzyme is inactivated, the produced enzymatically hydrolyzed solution is filtered, edible alcohol and auxiliary materials are added and blended, and the produced sea cucumber bio-alcohol is filtered by diatomite, filled, sterilized and packed. The sea cucumber bio-alcohol can increase the pH value of the acidic body fluid of the human body, enhance the activity of insulin, repair islet cells injured by the acidic constitution, recover the normal functions of islet cells and effectively reduce postprandial plasma glucose; and the sea cucumber bio-alcohol can strengthen metabolism, improve the acidic constitution, stabilize blood pressure, reduce blood sugar, blood fat, blood viscosity and the like, prevent and improve diabetes complication, notably reduce the activity of liver-injuring serum alanine aminotransferase and aspartate aminotransferase, increase the activity of liver SOD and reduce the content of MDA, thus having the function of protecting the liver.
