Supercritical fluid extraction
3.2.1. Effect of particle size
The effect of the particle size on the extraction yield was determined
using mean particle sizes of 0.842, 0.595 and 0.387mm at a
temperature of 40 ◦C, pressure of 300 bar and SC-CO2 flow rate of
4.0×10−5 kg/s.
Fig. 2 shows the extraction curves for each mean particle
diameter, resulting in extraction yields of 43.6, 44.7 and 44.9%, cor
