The process of extraction and purification process in a series of substu00e1ncias and active dyes from solid matrices, using CO2 supercru00ectico: Bixin from annatto
The process of extraction and purification equipment in a series of substu00e1ncias and active dyes from solid matrices, using Co ~ 2 ~ supercru00ectico: Bixin from annatto this invention deals with a process and equipment for obtaining fraction enriched in compounds the Claims and / or dye from solid matrices (leaves, roots, seeds, etc.In this special case) the seed of annatto (bixaorellana) by bringing together in a single process: (via supercritical extraction technology) and the fractionation / purification (column adsorption and elution) in which the extractor and the fracionador are in series. It is a process that does not require subsequent stages of decantation, filtration, centrifugation, removal of the solvent or aqueous solution and drying.It is a process that can occur continuously or semi continuously. In addition to being a selective process, using a solvent inert, non-toxic, low cost and does not generate residue of organic solvent; there is no contact with the light throughout the process (being a differential, as Bixin is fotodegradu00e1vel).Other features of the invention are that there is no contact with the ~ 2 ~ (to avoid the degradation of carotenoids) and extraction can be performed at temperatures of the process (around 30 to 70 198 C).
