How are oils and fats separated
Answers
Answer:
Separation of an edible oil into liquid and solid fractions. The edible oil is dissolved in about 0.5-4 parts by weight of a solvent being a C2 -C3 alkanol containing about 2 to 10% by weight of water and the solution is cooled to a temperature at which it separates into two liquid phases and a solid fraction crystallizes. The crystallized solid fraction floats in the upper liquid phase and is recovered therefrom. The liquid fraction of the oil is recovered from the lower liquid phase.
Answer:
Fats, also known as lipids, are natural constituents of many types of food. They can be either liquid or solid at room temperature. Oils are liquid at room temperature and are extracted by pressing, extraction and refining. Animal fats are solid at room temperature and are obtained by slowly melting the fat of meat.
