Cottonseed and peanut oils are destearinated, a process also known as winterizing, to ensure they remain liquid at low temperatures.
This procedure involves the removal of high-melting glycerides, often referred to as stearine. By cooling the oil slowly, these solid components form crystals that can be separated through filtration or centrifuging. Removing these saturated fats prevents the oil from becoming cloudy or solidifying when stored in a refrigerator, making it suitable for use as a salad oil.1
