Process for extraction of low phospholipid oil from oil-bearing material

Abstract From the Canadian patent

A process is disclosed for extracting a low phospholipid oil from an oil bearing material. The process comprises mixing a preselected reagent with the material for substantially separating non-hydratable phospholipids from the material to render them into hydratable phospholipids, and subsequently extracting the oil from the material. This processing reduces the phospholipid and trace metal content in the oil extracted from the oil bearing material. The oil product produced is light in color, shows no turbidity and exhibits a minimal amount of phosphorus, calcium, magnesium and iron. The oil is ready for physical refining.
