THE terms fat and oil are only loose descriptive words, bearing little or no technical significance, except to describe the physical state of a fat. If a fatty substance is usually solid at a temperature of 15°C (60°F), it is normally termed a fat; if liquid at that temperature, then it is usually called an oil. Fats and oils are distributed relatively freely throughout nature and can be classified as mineral, animal, and vegetable.
