Webster defines oil as any greasy substance that does not dissolve in water. There are many different categories of oil, which are obtained from numerous sources i.e. animal, vegetable and mineral. Edible oils are typically derived from animal and vegetable sources. These can be broken down into two categories: fixed and volatile. Fixed oil refers to oil that does not evaporate under normal conditions, while volatile oil or essential oil evaporates easily. Essential oils are used in flavors; fixed oils are used in cooking and baking. This article will discuss fixed oils, vegetable oils and seed oils.
