<P>PROBLEM TO BE SOLVED: To provide a process for treating an oil derived from microorganisms. <P>SOLUTION: This process for treating an oil comprises bringing the oil into contact with a polar solvent to extract at least one compound that is soluble in the solvent, and then separating the solvent containing the compound from the so treated oil. The oil is microbially derived, and extracted either from a fermentation broth or a filtrate thereof using hexane. The compound to be extracted is usually a sterol or a diglyceride. The solvent is ethanol having up to 5% water. The oil can contain a polyunsaturated fatty acid such as 18C, 20C or 22C ω-3 or ω-6 fatty acid, such as arachidonic acid. <P>COPYRIGHT: (C)2009,JPO&INPIT |
