Effects of chemical refinement on the quality of coconut oil
Refinement is usually used to remove undesired components to improve coconut oil quality. In the present study, crude coconut oil (CCO) was refined in four stages: conventional degumming, neutralization, bleaching, and deodorization. Physiochemical indices during the refinement were evaluated: peroxide value (PV), free fatty acid (FFA), fatty

Edible vegetable oils from oil crops: Preparation, refining
The free fatty acid releases of different edible oils were sorted from small to large: palm oil> rapeseed oil> linseed oil> sunflower oil> leaf lard oil. This result might be due to the significant differences in the types of fatty acids from different sources and their positions in the triglyceride molecule, which in turn significantly affects their digestibility.

14.10.1: Foods- Acid Value and the Quality of Fats and Oils
The acid value (AV) is a common parameter in the specification of fats and oils. It is defined as the weight of KOH in mg needed to neutralize the organic acids present in 1g of fat and it is a measure of the free fatty acids (FFA) present in the fat or oil. An increment in the amount of FFA in a sample of oil or fat indicates hydrolysis of

The fatty acid profiles of VCO and coconut oil are very similar, although studies have shown that VCO has a higher amount of lauric acid (46.0-52.6%), but not significantly. VCOs contain more medium-chain fatty acids, including significant amounts of lauric acid and other fatty acids, including caproic, caprylic, and capric acids [ 9 ].

Neutralization of Edible Oil to Remove Free Fatty Acids in Oil Refining Process - Oil Expeller. Edible Oil Production Line
Physical refining is to remove free fatty acids by steam distillation. Chemical refining is by neutralizing the FFA with alkali, which is often caustic soda, the chemical reaction creates soap stock, which settles down to the bottom of the tank and removed or separated by centrifugation. This process is called neutralization, or alkali refining.
