All about Palm Oil

Palm oil, one of the world’s most widely used vegetable oils, has been a subject of much debate and controversy. Derived from the fleshy mesocarp of oil palm fruits, palm oil is used in various products, from food to cosmetics. While it offers certain nutritional benefits, its production has raised significant environmental and social concerns.

The cultivation of oil palms dates back centuries to Southeast Asia, where they were originally grown for their edible fruits. In recent decades, the demand for palm oil has surged due to its versatility and relatively low cost, leading to a significant expansion of palm oil plantations worldwide.

Palm oil’s popularity can be attributed to its neutral flavour, high smoke point, and relatively low cost. It is used in a wide range of products, including cooking oils, margarine, and processed foods. 

While palm oil contains saturated fats, it is also a source of tocotrienols, a form of vitamin E with antioxidant properties. Some studies have suggested that tocotrienols may have health benefits, such as reducing cholesterol levels and improving heart health.

What is Palm Oil?

Palm oil is a vegetable oil extracted from the fleshy mesocarp of oil palm fruits. It is one of the most widely used vegetable oils in the world due to its high yield and relatively low cost. Palm oil is semi-solid at room temperature and has a yellowish-orange colour.

Palm oil is primarily composed of saturated fats, which can raise cholesterol levels if consumed in excess. However, it also contains tocotrienols, a form of vitamin E with antioxidant properties. Tocotrienols have been linked to various health benefits, including improved heart health and reduced inflammation.

While palm oil contains saturated fats, it has a different fatty acid profile than animal fats. Palm oil is rich in palmitic acid and oleic acid, which are saturated fats that may have less of a negative impact on cholesterol levels compared to other saturated fats.

How is Palm Oil made? The Extraction Process

After the initial extraction process, palm oil undergoes further refining and purification to improve its quality and stability. These processes may include:

Refining Palm Oil

Bleaching

The bleaching process involves treating the palm oil with a bleaching agent, such as activated carbon or clay. These agents absorb the natural pigments present in the oil, resulting in a lighter and more appealing colour. Bleaching is often used to improve the appearance of palm oil for cosmetic or food applications.

Deodorization

Deodorization is a process that removes any undesirable odours or flavours from the palm oil. This is achieved by heating the oil under a vacuum and passing steam through it. The steam helps to strip away any volatile compounds that contribute to off-flavours. Deodorization is essential for palm oil that is intended for use in food products.

Degumming

Degumming is a process that removes impurities known as phospholipids from palm oil. Phospholipids can affect the oil’s stability, appearance, and functionality. By removing these impurities, the oil’s quality and performance can be improved. 

Degumming is typically achieved by treating the oil with water or a mild acid, which causes the phospholipids to precipitate out. The precipitated phospholipids can then be removed through filtration or centrifugation.
