“…The extraction was performed at 200 bar and 50°C (CO 2 density, 0.785 g/cm 3 ) for 270 min. The yield of product recovered in the separator at the end of this second extraction step was 0.54% (with mean diameter of particles, 900 µm) and of 2.29% (mean diameter of particles, 400 µm) by weight of the charged material.…”

“…2 Nevertheless, supercritical CO 2 extraction coupled to a fractional separation technique to isolate essential oils has rarely been studied. A fractional separation of the supercritical extract in two or more separators operating at appropriate pressure and temperature conditions, is generally necessary to achieve the removal of cuticular waxes 3,4 from the extract. Carbon dioxide shows a high selectivity to essential oils at relatively low pressure.…”

“…Heat-caused damage in this method is relatively moderate, given that the CO2 solvent is separated from the extract by releasing the pressure and the extraction temperature is lower than the boiling points of water and organic solvents. Because of these features, sCO2 extraction is excellent for reproducibility of aromas of source materials (11,13,14,(16)(17)(18). The observed significant preference for the sCO2 extract may thus be explained by extraction of katsuobushi components with minimum damage.…”

“…Steam distillation is a method for obtaining volatile components by which a sample is heated in the presence of water, and volatile components distilled with water vapor are condensed and separated from the water. Although the principle is simple, steam distillation can damage compounds by pyrolysis and hydrolysis (13,14). Difficulties in obtaining a component with a low boiling point and high volatility or with high water solubility represent additional disadvantages of this extraction method.…”
