Characterization of grape seed oil extracted by supercritical carbon dioxide

open access: yesGrasas y Aceites, 1995
In this work the quality of grape seed oil obtained by extraction with supercritical carbon dioxide was studied. At the optimun operating conditions (313 K and 25 MPa), the yield of supercritical extraction is similar to the conventional extraction by ...

Modelling and experimental study of separators for co-solvent recovery in a supercritical extraction process [PDF]

open access: yes, 2006
Co-solvent recovery in supercritical extraction is addressed here through a theoretical description of the behaviour of a CO2 + co-solvent mixture into a cascade of cyclonic separators, such as those existing in conventional fractionation processes based

Comparison of different methods for extraction from Tetraclinis articulata: Yield, chemical composition and antioxidant activity [PDF]

open access: yes, 2013
In the present study, three techniques of extraction: hydrodistillation (HD), solvent extraction (conventional ‘Soxhlet’ technique) and an innovative technique, i.e., the supercritical fluid extraction (SFE), were applied to ground Tetraclinis articulata
