FIELD: chemistry.
SUBSTANCE: invention relates to the field of obtaining substances using supercritical media. A method is described for the extraction of capsaicinoids with supercritical carbon dioxide from pungent peppers in a supercritical fluid extraction unit, characterized in that the extraction is carried out in two stages, and in the first stage of extraction, carbon dioxide is used with the use of a co-solvent, which is used as distilled water, then the resulting extract, then the standard collection is replaced with a modified one, and the second stage is carried out, and liquefied carbon dioxide is used as a solvent for extraction in the second stage, after which the obtained extract is discharged into the collection.
EFFECT: isolation of two extracts: at the first stage, the isolation of the extract containing: capsaicinoids - 0.8-3.0% (of the total extract), essential oils - 0.5%, dyes - 72.0%, fatty oils - 1.0%, unidentified impurities - 20.0%; at the second stage - the isolation of the extract containing: capsaicinoids - 14-21% (of the total extract), essential oils - 23.0%, dyes - 14.0%, fatty oils - 43.0%.
