Refining Vegetable Oils: Chemical and Physical
Although refining extends oil shelf life, it has several disadvantages. One of the main disadvantages is the loss of substances responsible for healthy, pharmaceutical properties and technological interest in the oils, such as
The edible oil refining process is a critical step in ensuring high-quality, consumable oils for various applications. This process removes impurities, enhances stability, and aligns the oil with regulatory standards. It
Refining of edible oils ScienceDirect
However, chemical refining has proven to have a lesser effect on the desirable bioactive compounds compared to physical refining. Thus, chemical refining is still preferred and
Physical vs Chemical Refining. It depends mainly on the free fatty acid (FFA) content of the oil. If FFA content is very low then physical refining is very useful because by using lesser steam, oil
The difference between physical refining
Sometimes, physical refining and chemical refining methods will be used simultaneously according to the quality of the crude oil. As for which refining technology is better, it depends on your requirement. You can tell us your
Some include chemical refining with caustic soda neutralization and physical refining based on steam distillation [49, 50]. In chemical refining, the oil is treated with an alkali solution (caustic soda) that reacts with the free fatty

Two processes have been developed for the refining of edible oils and fats, i.e. physical and chemical refining; the decision which process to use depends on the types and
- What is the difference between chemical and Physical refining of edible oil?
- Chemical refining means chemically removing FFA (acid-base neutralization). In edible oil refining process, it utilizes alkali liquor to neutralize the acid in crude oil. 2. Different refining methods are suitable for different crude edible oil; Physical refining method is suitable for edible oil with high acid value:
- What is edible oil refining?
- Apart from chemical refining, physical refining is another method that used for edible oil refining. Through this method, the free fatty acids are removed during the process of distillation, which is one stage of deodorizing. The crude oil should be thoroughly degummed to come up with effective results.
- Which refining method is suitable for different crude edible oil?
- Different refining methods are suitable for different crude edible oil; Physical refining method is suitable for edible oil with high acid value: Physical refining method is mainly apply to the crude edible oil which has low phospholipid content and high acid value.
- What is the difference between deacidification and chemical refining of edible oil?
- In the process of deacidification of edible oil, no alkali is added for deacidification. Both deacidification and deodorization are carried out in a deodorization tower. The aid and odours can be removed by high temperature steam distillation. Chemical refining means chemically removing FFA (acid-base neutralization).
- What is Physical refining method?
- Physical refining method is mainly apply to the crude edible oil which has low phospholipid content and high acid value. It can reduce the loss of final edible oil and increase the added value of the product. (Like : crude palm oil, crude palm kernel oil and crude coconut oil and so on)
- Which method is suitable for edible oil with high acid value?
- Physical refining method is suitable for edible oil with high acid value: Physical refining method is mainly apply to the crude edible oil which has low phospholipid content and high acid value. It can reduce the loss of final edible oil and increase the added value of the product.
