| Resumo: | This work discusses some technical and economical issues related to supercritical extraction. The major steps in process development are discussed as applied to obtaining extracts from macela (Achyrocline alata and Achyrocline satureioides) and clove buds (Eugenia caryophyllus). Process data such as temperature, pressure, and yield are presented for obtaining extracts from black pepper (Piper nigrum), lemongrass (Cymbopogom citratus), bacuri (Platonia insignis), recovery of carotenoids from palm (Elaes guineensis) residue, Artemisia (Artemisia annua), ervabaleeira (Cordia verbenacea), fennel (Foeniculum vulgare), rosemary (Rosmarinus officinalis), ginger (Zingiber officinale), anise (Pimpinella anisum), etc.
