Zusammenfassung:	of the Invention The invention improves on the amorphous adsorbentbased processes by overcoming the soap leaching problem without using filtration before vacuum bleaching. For fatty materials containing only minor amounts of phospholipid and trace metal impurities, simply vacuum drying at least a portion of the soap-containing fatty material prior to contacting with the amorphous adsorbent eliminates the soap leaching problem. For fatty materials containing higher amounts of phospholipid and trace metals, simply using an acid pretreatment and the vacuum drying step eliminate the soap leaching problem.
