Abstract
Provided herein are methods for winterizing oil. The methods include 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.
