Abstract
PURPOSE:To selectively extract a blue pigment from blue-green algal cells in good yield and selectivity, by drying and powdering raw material algal bodies, heat-treating the dried powder and extracting the heat-treated powder with water. CONSTITUTION:Algal bodies of blue-green algae, such as the genus Spirulina, are preferably crushed by a wet method using a ball mill, etc., and dried by a conventional method, such as spray-drying or freeze-drying. The resultant dried powder is then heated at 60-150 deg.C, preferably about 100-120 deg.C for about 10min-2hr to immobilize or thermally denature chlorophyll, carotene, etc., contained in the algal bodies. The heat-treated powder is subsequently extracted with water to afford the aimed aqueous solution of the blue pigment.
