摘要：

Supercritical fluid extraction (SFE) of cholesterol from dry egg powder is performed with carbon dioxide delivered from cylinders containing either the native carbon dioxide vapor pressure or pressurized to approximately 1500 psi with helium. The extraction rate, with the conditions used, is 3 times slower for the helium head pressure carbon dioxide. © 1994, Oxford University Press. All rights reserved.
