PURPOSE:To obtain readily processable and treatable spirulina extract solution containing polysaccharides having immunopotentiation activities, etc., at a high concentration and excellent in preservation stability. CONSTITUTION:This method for producing a spirulina extract solution is to extract a spirulina alga body with hot water at a higher temperature than 100 deg.C, adjust pH of the residual alga body and the extract solution to the isoelectric point of the proteins or below, and remove coagulated proteins. Thereby, the extract solution which is optimal for a stock solution for processing a refreshing beverage, has a high content of polysacharides and is readily processable and treatable, and excellent in preservation stability can be obtained. |
