A Hidden Ingredient in Your Daily Life
You might not think about palm kernel oil, but it’s likely in your kitchen, bathroom, and even the fuel-powering industries.
It’s used in foods, skincare, soaps, and industrial applications worldwide. But how did this oil become so widespread? Understanding its history and global impact helps you see why it matters today.
History: Roots in West Africa
My grandmother, before she passed never lacked an old bottle of palm kernel oil tucked away under his bed where it will always be within rich.
Palm kernel oil has been a part of West African culture for centuries, used in trade, cooking, and traditional medicine.
European merchants encountered it in the 15th century, leading to its introduction into global commerce.
By the 19th century, demand surged as industries in Europe and North America used it in soap-making, candles, and lubricants.
During the colonial era, palm-rich regions saw increased cultivation, with plantations expanding in Africa and later Southeast Asia.
By the 20th century, Malaysia and Indonesia became the dominant producers, shifting the industry’s center from Africa to Asia.
Today, PKO remains a key player in food, cosmetics, and industrial applications, with ongoing discussions about sustainability and environmental impact.

How Palm Kernel is Extracted: I Used to Watch My Grany 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 bring oil which is collected.
And just like that, she had pure, homemade palm kernel oil, rich, unrefined, and full of goodness.
Today, palm kernel oil 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.
Economic Power and Environmental Concerns
PKO plays a key role in the global economy, supporting jobs and trade in producing countries.
But its growth comes with challenges. Expanding palm plantations has led to deforestation, habitat loss, and concerns over sustainability.
As awareness grows, consumers and businesses push for eco-friendly practices, leading to certifications like RSPO (Roundtable on Sustainable Palm Oil) to ensure responsible sourcing.

Palm Kernel Oil Other Oils
If you’re trying to choose the right oil for cooking, skincare, or manufacturing, you might wonder how PKO, palm oil, and coconut oil compare.
These three oils come from tropical plants, but their differences in extraction, composition, and uses make each one unique.
Palm Kernel Oil vs. Palm Oil
The biggest difference between these two oils comes down to where they come from in the oil palm tree (Elaeis guineensis):
- Palm kernel oil is extracted from the seed (kernel) inside the fruit.
- Palm oil comes from the fleshy outer part of the fruit.
This distinction affects their fat content and texture:
| Property | Palm Kernel Oil | Palm Oil |
|---|---|---|
| Fat Type | High in saturated fats (about 80%) | More balanced with saturated and unsaturated fats |
| Texture | Solid at room temperature | Semi-solid but softer |
| Best Uses | Baking, frying, soaps, cosmetics | Cooking, processed foods, industrial applications |
Because PKO has more saturated fat, it stays solid at room temperature, similar to coconut oil.
This gives it a longer shelf life and makes it great for products like chocolates, margarine, and soaps, where a stable fat source is needed.
Palm oil, on the other hand, has a mix of saturated and unsaturated fats, making it more versatile for cooking and food manufacturing.
Palm Kernel Oil vs. Coconut Oil
Since both palm kernel oil and coconut oil contain a high percentage of saturated fats, they share some similarities.
However, their fatty acid composition sets them apart:
| Property | Palm Kernel Oil | Coconut Oil |
|---|---|---|
| Main Fatty Acid | Lauric acid (C12:0) (~48%), plus myristic, palmitic, and oleic acids | Lauric acid (C12:0) (~50%), plus caprylic and capric acids |
| Chain Length | Mix of medium and long-chain fatty acids | Mostly medium-chain fatty acids (MCTs) |
| Absorption & Digestion | Slower digestion (more long-chain fats) | Quick metabolism (faster energy source) |
| Best Uses | Soap-making, skincare, frying | Cooking, hair and skin care, keto diet |
Coconut oil is rich in medium-chain triglycerides (MCTs), which your body digests quickly and converts into energy. This makes it a popular choice for keto diets and energy-boosting supplements.
Palm kernel oil, while also high in lauric acid, contains more long-chain fatty acids, making it better suited for cosmetic and industrial applications, like soap-making and skincare.
