Method for extracting functional polysaccharide derived from mushroom mycelium and culture solution thereof, and method for manufacturing functional tea and food using the extract

PURPOSE: Provided are a method for extracting functional polysaccharide derived from mushroom mycelium and its culture solution, and a method for manufacturing functional tea and a food using the extract, thereby obtaining nucleic acid, amino acid, protein and polysaccharide in high yield without damage. CONSTITUTION: A method for extracting functional components such as polysaccharide, nucleic acid, amino acid, and protein derived from mushroom mycelium and its culture solution comprises the steps of: separating mycelium from a mushroom mycelium culture solution; homogenizing it within a range of 5000-6000rpm for 0.01-30 minutes, 1-15 times; and irradiating microwave(1000-3000MHz) for 1-30 minutes, 1-30 times.
