Abstract
Disclosed is a process for recovering an edible oil, such as soybean or canola oil, from an adsorbent material, such as a bleaching agent, by contacting a feed of the adsorbent material containing the edible oil with a normally gaseous solvent, such as liquid propane, for a time sufficient to extract a substantial portion of the oil from the adsorbent material, before the oil degrades to an appreciable extent.
