摘要
PURPOSE:To extract selectively a blue pigment in a good yield with a good selectivity from the cells of blue-green algae in a simple step, by crushing a blue-green alga, drying it, irradiating it with light and extracting a blue pigment with an aq. extractant. CONSTITUTION:The cells of a blue-green alga are crushed, dried and then irradiated with light. The irradiated product is treated with an aq. extracted to extract a blue pigment. Various blue-green algae can be used as the starting material and a typical example thereof is one belonging to the genus spirulina. The cells can be crushed, e.g., by a wet-process ball mill method, ultrasonic treatment, etc. The irradiation can be conducted by irradiating the cells with visible light of 1,000-10,000lx for 1-10 days. The crushed product is dried by freeze-drying, spray drying, etc.
