The invention relates to spirulina blue polysaccharide green bear, liquor and beverage and a preparation method, which are formed through the following steps: firstly extracting pure polysaccharide and phycocyanobilin from spirulina and extracting chlorophyll from bamboo leaves; then adding in proportion, mixing the pure polysaccharide, phycocyanobilin and chlorophyll with edible alcohol and distilled water and stirring; preparing spirulina blue polysaccharide extracting solution after pasteurization and sterilization; and adding the extracting solution in proportion to bear, white spirit and series liquor and beverage so as to prepare functional green bear, functional white spirit, rectifying fruit wine series liquor and beverage, wherein the spirulina blue polysaccharide extracting solution comprises the following components by weight ratio: 2%-16% of spirulina pure polysaccharide, 0.5%-10% of spirulina phycocyanobilin, 1%-20% of chlorophyll of bamboo leaves, 5%-15% of edible alcohol and 39%-91.5% of distilled water, and the total proportion is 100%. According to the invention, the adopted spirulina pure polysaccharide contains no protein, and the phycocyanobilin contains no protein, so that the spirulina blue polysaccharide extracting solution adopted in green bear, liquors and beverage has the radiation protection function.
