Abstract
A method of producing fatty acids and glycerol from oleaginous materials utilizing comminuted seeds as an immobilized lipase catalyst. The comminuted lipase-containing seeds are combined with an oleaginous material, an organic solvent and water with the resultant heterogenous mixture being agitated under non-energy intensive conditions to provide free fatty acids and glycerol. The lipase catalyst may be recovered and recycled.
