Accelerated supercritical fluid extraction process

In a process of extracting a solute from a particulate egg substrate with supercritical fluid under supercritical conditions, the improvement comprising:

• forming said substrate into porous, non-spherical, solid particles characterized by a number weighted mean particle size ranging from about 0.5 millimeters to about 3 millimeters and by a tapped bulk density of from about 0.2 to about 0.5 grams per milliliter prior to subjecting the substrate to extraction under supercritical conditions.
