Winterizing

Some vegetable oils, when stored in the refrigerator, do not stay completely liquid. The cooler temperatures may result in cloudiness from the crystallization of certain fatty acids that have a higher melting point than their neighboring fatty acids. This cloudiness may be eliminated by winterizing the oil - a commercial process that lowers the temperature of the oil, allowing the fatty acids with higher melting points to crystallize so that they may be filtered out.
