SUPERCRITICAL CARBON-DIOXIDE EXTRACTION OF CARDAMOM

Cardamom (Eletteria cardamomum Maton) seeds were extracted with supercritical carbon dioxide at different conditions of pressure, temperature, contact time, and moisture content to estimate the yield and compositional variations. The yield of cardamom extract was found to be fairly constant at different conditions of extraction, but the nonvolatiles and chlorophyll contents varied in the extract with extraction parameters. The proportion of minor and major components also showed variations under different conditions of extraction.
