NOVELTY – The method involves using supercritial carbon dioxide and seeds of urucum for extracting through supercritial technology and fractionation or purification, where extractor and fractioning unit are in series, and a nontoxic and inert solvent is used. The method has no contact with oxygen to avoid degradation of carotenoids and extraction is made at certain temperatures. USE – Method for extraction and purification in multiple active substances and dyes from solid matrix as leaves, roots, seeds. ADVANTAGE – The method ensures low-cost and does not generate waste of organic solvent.
J01 (Separation – including evaporation, crystallisation, solvent extraction, chromatography, dialysis, osmosis including drying gases and/or vapours, and separation of solids from gases, liquids and other solids. Isotope separation, filter materials (including molecular sieves for separation), and centrifuges (except where used for analysis) (B01D, B03, B04, B07B).)
