Palm Oil Refining Process

Palm Oil Refining Process

Palm oil refining industries are most important manufacturing sectors in the world and Palm oil has become an increasingly important vegetable oil in the world market and today is the largest traded vegetable oil in the world. Malaysia is the largest producer and exporting company of Crude Palm oil.

Crude Palm oil is obtained from mesocarp part of palm oil. Extracted Crude Palm oil contains some undesirable impurities and these some of the impurities need to be removed partially or completely through the refining process in order to produce good edible oil that have better stability and keepability.

Palm Oil Refining Process

Now a days Palm oil is popular cooking oil in some tropical countries like South east Asia, Africa, and some parts of Brazil. It is broadly used in other countries because of lower cost and good oxidative stability. Palm oil is used widely for cooking due to its heat resistant property as compared to any other vegetable oil.

Palm Oil Refining Process

The unique and best quality of Palm is that it produces two types of oil: – Palm Oil and Palm Kernel oil.

Palm oil is extract from the flesh of the Palm fruit and Palm Kernel Oil is extract from the seeds or kernel of the Palm fruit.

The palm oil is extracted by the fresh palm fruit flesh by pressing & centrifugation. The palm oil extraction is to be done with the fresh palm fruit to avoid the deterioration of palm oil so the countries doing the cultivation are extracting the oil themselves. The crude palm oil comes out as yellow red or dark yellow in color and the taste of the crude palm oil is sweat.

Before going on refining / purifying process of palm oil we would like to give brief introduction about processing of Fresh fruit bunches (FFB) of Palm which includes the Harvesting of the palm fruit from the trees, the threshing which means to remove the palm fruits from its bunches. After this sterilization is done in which steam under pressure in applied on the palm fruit which helps to remove the palm fruit from the bunches. The digestion is done after sterilization which ruptures the oil bearing cell increases the extractability of the oil in the pressing section. In the pressing section the palm fruit / palm kernel enters into screw oil press/expeller to press because it yields the CPO (Crude Palm Oil).

Palm Oil Refining Process

The Crude Palm Oil Extracted from the above method does contains the unwanted impurities which effect adversely on the physical appearance, quality, oxidative stability, shelf life of the oil. In order to remove the above impurities, the oil goes to the refinery plant in order to receive the RBD Palm Oil (Refined Bleached & Deodorized). After refining of the palm oil the RBD oil goes to the fractionation section in order to get the palm olein and stearin.

Refining is the process in which we remove the undesirable impurities from Crude Palm oil as mentioned below.

• Phospholipids
• Free fatty acid
• Coloring pigments (Carotenoids).
• Moisture, oxidative material, metal impurities, and water soluble impurities (glycerol, Phenols, Sugars).

The term refining includes the removal of above impurities in order of increasing shelf life and quality of Refined Vegetable oil.
