Coconut oil is an incredibly healthy fat.
It’s rich in several medium-chain fatty acids that can have powerful effects on your metabolism.
Fractionated coconut oil is made from coconut oil and mainly consists of two medium-chain fatty acids.
It has been marketed as a coconut oil that can stay in liquid form in the fridge.
This is a detailed review of fractionated coconut oil and its health effects.
What is fractionated coconut oil?
Fractionated coconut oil is an oil made from regular coconut oil.
Both regular and fractionated coconut oils are great sources of medium-chain triglycerides (MCTs), providing fatty acids that contain 6 to 12 carbon atoms.
However, their fatty acid composition is vastly different.
While the main fatty acid in coconut oil is the 12-carbon lauric acid (C12), most or all of this fatty acid has been removed from fractionated coconut oil.
The long-chain fatty acids present in coconut oil have also been eliminated.
Thus, the main medium-chain fatty acids (MCFAs) in fractionated coconut oil are:
C8: caprylic acid or octanoic acid
C10: capric acid or decanoic acid
MCFAs are metabolized differently than other fats.
They’re transported directly to the liver from the digestive tract, where they may be used as a quick source of energy. They can also be turned into ketone bodies, which are compounds that may have therapeutic effects in those with epilepsy (1Trusted Source).
Fractionated coconut oil is tasteless, odorless, and usually more expensive than regular coconut oil.
It’s very similar or even identical to MCT oil.
Fractionated coconut oil is made from regular coconut oil and mainly consists of the medium-chain fatty acids caprylic acid (C8) and capric acid (C10).
How is fractionated coconut oil made?
Fractionated coconut oil is produced via a process called fractionation.
Fractionation is used to separate different types of fats that are naturally found in some oils. It’s often done to make new products for consumers (2).
The different melting points of various fats make fractionation possible.
For example, lauric acid and long-chain fatty acids have higher melting points than caprylic acid and capric acid. Therefore, they will become solid sooner when cooled.
The fractionation of coconut oil is carried out by heating the oil above its melting point. Then, it’s left to cool, and the solid fraction of the oil is separated from the liquid.
The whole process of fractionation can take several hours.
