What is Refined Palm Oil?

Refined palm oil is one of the types of palm oil from palm oil fruit from the palm oil tree, different from red palm oil, and a popular ingredient found in many of the foods and products we use daily.

It is a processed oil, unlike crude palm oil, which retains its natural color and flavor. Refined palm oil undergoes a series of treatments, including bleaching and deodorizing, to remove impurities and make it more neutral in taste and appearance.

This process also increases its shelf life and stability at high temperatures, which is why it’s commonly used in cooking, frying, and packaged food products.

It’s popular for its affordability and ability to maintain consistency in food preparation, but its production can raise environmental concerns due to deforestation.

How Refined Palm Oil is Made

The refining procedure of palm oil involves many steps that turn crude palm oil into a high-quality, pliable product suitable for consumption and many industrial applications.

The refining process begins with:

  • Degumming
  • Neutralization
  • Bleaching and
  • Deodorization

Each of these steps adds to the quality of the end product by eliminating impurities, sediments, flavors, and odors that are not needed.

Let’s take a closer look at the processes:

Degumming

Degumming is the first process in the refining of crude palm oil to get refined palm oil. This step gets rid of phospholipids from crude palm oil, including impurities.

The process is effective with the mixture of phosphoric acid or citric acid in water with the crude palm, triggering the separation of acidic components.

A centrifuge is the main equipment for this process, as separation is the main objective.

The end product in this process is a cleaner oil ready for the next phase of refining.

Neutralization

Neutralization is the next step after degumming. This process is designed to extract and remove fatty acids that have a direct effect on the behavior of the refined oil, like taste and stability.

This process involves the use of sodium hydroxide, an alkali solution, to react with the free acids, which produces a soap-stock formation that is then removed from the oil with settling tanks or centrifuges.

This process of neutralization helps in improving the shelf life of the refined oil while further making the taste neutral.

Bleaching

Bleaching is the third process and involves the treatment of the neutralized oil with absorbent materials to eliminate the color to give it the popular golden color. Heat is used in this process to quicken the absorption.

The absorbent material can be clay or activated carbon, which helps to also remove impurities and residues.

Deodorization

Deodorization is the last process in refining the crude palm oil to get the refined palm oil.

This works by removing compounds that give the palm oil its odor as much as possible to make it odorless and further improve its taste.

Under high temperatures and vacuum, steam distillation is used to achieve this result.

This last process of deodorization makes the refined palm oil have a long shelf-life and stability and to be used in many applications.

Can Refined Palm Oil Be Refined Locally or Traditionally?

As a child in a palm oil community, I never cared about refined palm oil or even thought our precious red oil (crude palm oil) could be refined further.

This is because red palm oil serves every purpose we need it for and also has a minimal shelf life.

However, refining palm oil locally or traditionally is possible ,but not as common as large-scale industrial processes.

Traditional methods involve boiling or pressing the palm fruit to extract the oil, followed by basic filtration to remove impurities.

However, this crude oil retains a strong flavor and color, unlike the neutral refined version.

For more refined products, the oil would need further processing like bleaching, deodorizing, and removing contaminants, as we have mentioned abov,e and this requires specialized equipment.

While small-scale or local refiners may use simpler techniques, large-scale refining ensures the oil is purified to meet safety standards and extend shelf life.

Characteristics of Refined Palm Oil
