(5) step (4) gained Phycocyanins, C-extracting solution is carried out to hig h-speed centrifugal spray drying, collect powder, obtain Phycocyanins, C-.
The buffered soln of described step (2) is the sodium radio-phosphate,P-32 solution that pH is 6.5, concentration is 0.1M.
The high pressure homogenization broken wall of described step (2) is to complete on conventional high pressure homogenizer.
Centrifugation 20~30min under the condition that the centrifugation of described step (3) is is 3500~5000r/min at rotating speed.
The combined resin of described step (4) is two or more the combination in D900 type ion exchange resin, HPD-300L type resin, the large mesh nonpolar adsorption resin of BEHP-3 type, the large mesh nonpolar adsorption resin of BEHP-4 type, D112 sun resin, and portfolio ratio is arbitrarily.
The hig h-speed centrifugal spray drying of described step (5) is to be that 2~8L/h, inlet temperature are that 180~320 ℃, air outlet temperature are that 80~90 ℃, drying temperature are to carry out under the condition of 160~220 ℃ in liquid feeding speed.
The advantage that the present invention possesses and effect: by the present invention, can extract to greatest extent Phycocyanins, C-; and product can not be secondary polluted; the operation of the present invention from broken wall, separation and purification to drying and other steps all convenient and easy, feasibility is strong; can accomplish scale production; in production process, not discharging pollutants, is a kind of environment amenable Phycocyanins, C-extracting method.Phycocyanins, C-content in spirulina is generally 3~10%, and the extraction yield that adopts method of the present invention to extract Phycocyanins, C-in spirulina is that more than 90.0% product purity reaches A620/A280>3.2.
