A two-step fractionation method for winterizing oil

Provided herein are methods for winterizing microbial oils. In prior art winterizing methods involving dry fractionation a large amount of solids are removed, resulting in a poor liquid oil yield. The method of the invention allows for higher liquid oil yield by stepwise temperature adjustment and solid removal without loss of liquid fraction of the oil. The method as claimed involves heating the oil to a first temperature and maintaining the oil at the first temperature for a first period of time; reducing the first temperature of the oil after the first period of time to a second temperature over a second period of time, wherein reducing the first temperature produces a first solid fraction and first liquid fraction of the oil; removing the first solid fraction from the oil; reducing the second temperature of the first liquid fraction of the oil over a third period of time to a third temperature, wherein reducing the second temperature of the oil produces a second solid fraction and second liquid fraction of the oil; removing the second solid fraction from the oil; and recovering the second liquid fraction of the oil; wherein the oil is a microbial oil; and wherein the method is performed in the absence of solvent. The recovered liquid fraction may be utilized to produce biofuel or in pharmaceuticals, nutraceuticals, food supplements, animal feed additives and cosmetics.
