The invention relates to biotechnology, particularly to a process for producing the myxoxanthophyll carotenoid pigment from Spirulina platensis biomass for use in the food industry or medicine.According to the invention, the process consists in that it is carried out re-extraction of myxoxanthophyll from the biomass with 70…96% water-ethanol solution with separation of biomass by centrifugation and unification of produced extracts, to which is added 40% potassium hydroxide in a ratio of 3:1 to the amount of the extracted biomass, is maintained for 4…6 hours and is added hexane, afterwards by decantation is separated the myxoxanthophyll-containing ethyl fraction, which is diluted with water to the ethyl alcohol concentration of 45…50%, is centrifuged at 6000 rev/min, and the resulting crystals are washed with 45…50% ethanol solution and dried. |
