Title
(EN) METHOD FOR OBTAINING AN AQUEOUS SOLUTION ENRICHED WITH BLUE PIGMENT
(FR) PROCEDE D'OBTENTION D'UNE SOLUTION AQUEUSE ENRICHIE EN PIGMENT BLEU
Abstract
(EN)
The present application relates to a method for obtaining an aqueous solution enriched with blue pigment, comprising the steps of a) providing an aqueous solution comprising a blue pigment derived from at least one microorganism of the genus Haslea, b) precipitating the blue pigment with sodium hydroxide, c) separating the precipitated phase from the aqueous phase, d) solubilizing the blue pigment included in the precipitated phase, and e) the step of dialysis.
