Abstract

Lipid retention in novel pressurized solvent extraction vessels was examined as a function of static and flushing cycles, flushing flow rate and flush volume in an effort to decrease lipid elution after extraction. Results indicate that none of these variables plays a pivotal role in lipid retention within this system. Regardless of which variable was altered, lipid elution remained virtually constant at (55 ± 7) %. Findings suggest that lipid elution has more to do with the high flow rate at which extracts are purged from the system at the end of the static cycle.
