Discover everything about palm kernel oil (PKO), from its types, benefits, uses, and extraction to sustainability and industry insights, in this ultimate guide to one of the world’s most versatile oils!
PKO comes from the seed of the oil palm tree, not the fruit’s flesh that produces palm oil and the crude palm oil, but the hard seed at the core of the fruit.
Though they come from the same tree, their composition, properties, and uses are different. Palm kernel oil is a general term for different types, including refined, crude palm kernel oil, organic, hydrogenated, and fractionated variants.
This oil has been used for generations in West Africa, Southeast Asia, and South America, but its rising demand brings concerns about sustainability and deforestation.
As someone who has lived all my life processing, eating, and using red palm oil and its coproduct, PKO, I have a lot to say about this incredible palm kernel oil.
Growing up, I saw people, especially of older generations, use palm kernel oil to cure convulsions and high fever.
A sick child with a high fever gets better when crude palm kernel oil (CPKO) is rubbed all over and a few drops into the mouth.
While it may not be the cure for a lot of illnesses, it helped arrest fevers and inflammations, but I can’t say the same for the refined palm kernel oil from experience.
You’ve probably used palm kernel oil without realizing it. It’s in your snacks, skincare, and even household products.

Extraction of Palm Kernel Oil: Local and Modern Methods
Palm kernel oil extraction has evolved from traditional manual techniques to advanced industrial processes.
Both local and modern methods are still in use today, depending on the scale of production and intended application.
Local Method: I Used to Watch My Granny Do It
I used to watch my granny extract palm kernel oil using a traditional method passed down through generations.
There are two methods she uses – cracking and heating, or cracking, pounding, and heating.
She began by extracting the palm kernel seeds, cracking open as many as needed to free them from their hard shells.
Once collected, she pounded the seeds in a mortar until they became fine particles, a process that can now be done with a blender.
She then added water and sometimes let the mixture sit for a few hours or even overnight, though this step wasn’t always necessary.
Next, she transferred the mixture into a pot and heated it until it turned a deep brown color. Once ready, she removed it from the heat, allowed it to cool, and then strained it through a cloth to separate the oil.
The second method is to heat the seeds for an hour after cracking. Under heat, the seeds begin to release oil, which is collected.
And just like that, she had pure, homemade PKO, rich, unrefined, and full of goodness.
Today, PKO can be extracted with modern machines. The kernels are then cleaned, dried, and cracked to remove the hard shell, leaving the inner seed.
Next, the kernels undergo mechanical pressing or solvent extraction.
Cold pressing uses a screw press to extract oil without high heat, preserving nutrients, while solvent extraction uses chemicals like hexane to maximize yield.
The crude oil is then filtered and refined to remove impurities, resulting in a clear, pale yellow oil.
Modern Methods
Industrial extraction methods have improved efficiency and oil quality. Mechanical pressing uses machines to apply pressure on the kernels, squeezing out the oil while leaving behind a dry cake.
This method is common in medium-scale operations.
Cold pressing is a modern technique that extracts oil without heat, preserving nutrients and natural flavor.
It is preferred for high-quality cosmetic and edible oils but produces a lower yield.
Solvent extraction is used in large-scale production. It involves soaking the crushed kernels in chemical solvents to dissolve the oil, which is then separated and refined.
This method extracts the maximum amount of oil but requires extra processing to remove solvent traces.
Once extracted, both crude and refined PKOs may undergo further refining to enhance purity and shelf life, making them suitable for food, cosmetics, and industrial applications.
Types of Palm Kernel Oil
Palm kernel oil comes in different forms, each with its own qualities and uses.
Knowing the differences helps you choose the right type for cooking, skincare, or industrial applications.
Let’s take a closer look:
Crude Palm Kernel Oil (CPKO): Extracted without refining, CPKO retains its natural color, antioxidants, and fatty acids. It is used in cooking, cosmetics, and industrial applications like soap and detergent production.
Refined Palm Kernel Oil (RPKO): Processed to remove impurities, RPKO is lighter in color and neutral in taste. It is widely used in food production, cosmetics, pharmaceuticals, and household products due to its stability.
Hydrogenated Palm Kernel Oil (HPKO): Modified to remain solid at room temperature, HPKO enhances texture and shelf life in baked goods, confectionery, and processed foods. Some versions contain trans fats, raising health concerns.
Organic Palm Kernel Oil (OPKO): Sourced sustainably without synthetic chemicals, OPKO is used in food, cosmetics, and skincare. Choosing OPKO supports ethical farming, reduces environmental impact, and promotes responsible land use.
