The Meaning of Cooking Oil | Definition of Cooking Oil

noun
Any of numerous vegetable oils used in cooking

Cooking Oil is a liquid or solid fat derived from plants or animals used for cooking purposes. It is commonly used to fry, sauté, or bake food, providing a way for heat to reach the food and making it taste better.
Examples include vegetable oil, olive oil, coconut oil, and lard. Cooking oil is a versatile ingredient in the kitchen, adding richness and texture to dishes while also helping cook them.
The fats in solid cooking oil are either highly saturated or they have been hydrogenated. Hydrogenation transforms liquid cooking oils into solid fats in a process that produces trans-fats.
Trans-fats are harmful to human health. The FDA says that there is no safe level of trans fat in the diet. Trans fats in foods are more likely to cause heart disease than saturated fats or cholesterol in our foods.

Example in a Sentence
Its jet fuel is blended from used cooking oil, animal fats and other wastes and residues.
