Structural change considered to have little or no detrimental effect on the animal; may be transient and may occur relatively frequently in the control population

Winterization is a process whereby waxes are crystallised and removed in a filtering process to avoid clouding of the liquid fraction at cooler temperatures. The term winterization was originally applied decades ago when cottonseed oil was subjected to winter temperatures to accomplish this process. Winterization processes using temperature to control crystallization are carried out on sunflower and maize oil. A similar process called dewaxing is utilized to clarify oils containing trace amounts of clouding constituents
