Why My Palm Oil Community thinks Palm Kernel Oil Should not be Refined

In my hometown where we are known for palm oil cultivation and processing, we don’t see much reason why the palm kernel oil should be further refined, and there is a strong reason behind that.

While the refining of palm kernel oil might make it visually appealing with other benefits, my people believe it is not necessary as most of its compositions are lost along the way.

But industry stalwarts think otherwise.

For instance, refined crude palm kernel oil is not effective in tackling convulsions like raw ones, and this loss is not the only one.

From some of the experiments we have made, a lot happens while trying to make the crude palm kernel oil better. We think it’s a pyrrhic victory.

Production Process of Refined Palm Kernel Oil

Palm kernel oil undergoes a series of processes to remove impurities, improve stability, and make it suitable for food, cosmetic, and industrial applications.

Extraction of Crude Palm Kernel Oil

The first step in producing RPKO is extracting crude palm kernel oil (CPKO) from the palm kernels.

This is done through two primary methods:

• Mechanical Pressing: Palm kernels are cleaned, dried, and crushed to release the oil. The remaining kernel cake can be used as animal feed or for other industrial purposes.

• Solvent Extraction: A chemical solvent, such as hexane, is used to extract the oil from the kernel cake left after mechanical pressing. This method increases oil yield and is widely used in large-scale production.

After extraction, the crude oil is filtered to remove solid particles before entering the refining process.

Refining Process

To make the oil suitable for consumption and industrial use, crude palm kernel oil undergoes several refining steps:

1. Degumming

Water and acid are added to remove phospholipids, gums, and other impurities that can affect the oil’s stability and quality. This step ensures a smoother refining process.

2. Neutralization

An alkali, such as sodium hydroxide, is introduced to neutralize free fatty acids. This prevents rancidity, removes unwanted flavors, and extends shelf life.

3. Bleaching

Natural adsorbents like activated clay are used to remove color pigments and other impurities. This process improves the oil’s appearance and enhances its usability in food and cosmetic products.

4. Deodorization

The oil is heated under vacuum conditions to remove volatile compounds responsible for undesirable odors.

This step ensures the oil is odorless and suitable for various applications.

Quality Control and Testing

Throughout the production process, refined palm kernel oil undergoes strict quality control measures.

Key parameters tested include:

• Fatty Acid Composition: Ensuring the right balance of saturated and unsaturated fats.
• Free Fatty Acid Levels: Maintaining low levels to prevent spoilage.
• Moisture and Impurities: Ensuring purity and longer shelf life.

Nutritional Composition of Refined Palm Kernel Oil

Refined palm kernel oil (RPKO) comes from the seed of the oil palm fruit. Its composition sets it apart from many other vegetable oils.

Unlike sunflower or canola oil, which contain more unsaturated fats, RPKO is about 80% saturated fat.

Fatty Acid Profile

The primary fatty acids in RPKO include:

• Lauric acid (≈48%) – Known for its antimicrobial properties.
• Myristic acid (≈16%) – Plays a role in metabolism.
• Palmitic acid (≈10%) – Common in many fats and oils.

This high saturation level makes RPKO stable at high temperatures, which is why it’s commonly used in frying and processed foods.

How It Affects Your Health

Because RPKO is rich in medium-chain fatty acids, your body can break them down quickly for energy instead of storing them as fat.

Some studies suggest lauric and myristic acids may help with metabolism and satiety, making you feel full longer.

However, compared to oils like olive or flaxseed, RPKO lacks significant phytonutrients and antioxidants. If you’re looking for heart-healthy fats, you may want to balance your intake with unsaturated oils.

Vitamins and Micronutrients

RPKO contains small amounts of:

• Vitamin E – Supports skin health and has antioxidant properties.
• Vitamin K – Plays a role in blood clotting.

Unlike red palm oil, which is rich in carotenoids, RPKO loses most of its natural nutrients during the refining process.

How Does RPKO Compare to Other Oils?

• Coconut oil – Similar in fatty acid composition but contains more medium-chain triglycerides (MCTs), which may offer additional metabolic benefits.
• Olive oil is high in monounsaturated fats and antioxidants, making it a better choice for heart health.
• Vegetable oils (canola, sunflower, soybean) – Contain more unsaturated fats, which may help manage cholesterol levels.

Uses and Applications of Refined Palm Kernel Oil

Health Benefits and Concerns of Refined Palm Kernel Oil

Refined palm kernel oil (RPKO) is widely used in cooking, cosmetics, and processed foods, but is it good for your health?

Like any oil, it has benefits and drawbacks. While it provides quick energy and antimicrobial properties, its high saturated fat content raises concerns for heart health.

Let’s take a closer look at what RPKO offers and where caution is needed.

Health Benefits of Refined Palm Kernel Oil

1. A Quick and Efficient Energy Source

One of the biggest advantages of RPKO is its medium-chain triglycerides (MCTs), particularly lauric acid.

Unlike long-chain fats, MCTs are rapidly absorbed and converted into energy, making them an ideal fuel source for:

• Athletes and fitness enthusiasts who need quick energy during workouts.
• People are on low-carb or ketogenic diets, where fat is the primary energy source.
• Those struggling with fat malabsorption issues, as MCTs, are easier to digest than other fats.

2. May Support Weight Management

Some studies suggest that MCTs in palm kernel oil can contribute to weight control by:

• Boosting fat metabolism – Your body burns MCTs faster than long-chain fats, which may help with calorie burning.
• Increasing satiety – MCTs can help you feel full longer, reducing overall calorie intake.

However, weight loss effects vary from person to person and depend on overall diet and lifestyle.

3. Antimicrobial and Antifungal Properties

Lauric acid, which makes up nearly half of the fat content in RPKO, has been studied for its antibacterial, antiviral, and antifungal properties.

Research suggests that lauric acid can help combat harmful pathogens like:

• Staphylococcus aureus – linked to skin infections and food poisoning.
• Candida albicans – a common cause of fungal infections.
• Certain viruses, though more research is needed to confirm its effectiveness in humans.

This makes RPKO useful in food preservation, cosmetics, and even some medicinal applications.

4. Shelf-Stable and Heat-Resistant

With 80% saturated fat, RPKO is highly resistant to oxidation, meaning it doesn’t spoil as quickly as unsaturated oils. This makes it a popular choice for:

• Deep frying – High stability prevents breakdown at high temperatures.
• Processed foods – Helps extend shelf life in baked goods, snacks, and margarine.
• Cosmetics and skincare – Used in creams and lotions to improve texture and longevity.

Health Concerns of Refined Palm Kernel Oil

1. High Saturated Fat Content and Heart Health Risks

While MCTs have potential benefits, the overall saturated fat content in RPKO is about 80%, higher than coconut oil (around 65%) and butter (around 50%).

Excessive intake of saturated fat is linked to:

• Increased LDL cholesterol (“bad” cholesterol), which may contribute to artery blockages.
• Higher risk of heart disease and stroke, especially in people with existing cardiovascular conditions.
• Potential weight gain if consumed in excess, as high-fat diets are calorie-dense.

However, some research argues that not all saturated fats are harmful and that the effects depend on overall diet quality.

The key is moderation and balance with healthier fats like olive oil, avocado, and nuts.

2. Lack of Essential Nutrients

Compared to extra virgin olive oil or flaxseed oil, which contain beneficial antioxidants and polyphenols, RPKO has minimal vitamins and phytonutrients.

It provides small amounts of:

• Vitamin E – A natural antioxidant, but not as high as in red palm oil.
• Vitamin K – Plays a role in blood clotting, though levels are minimal.

If you rely heavily on RPKO, consider supplementing with nutrient-rich oils to maintain a balanced intake of antioxidants and healthy fats.

How to Use Refined Palm Kernel Oil Wisely

If you want to include RPKO in your diet while minimizing risks, here’s how to do it:

• Use it in moderation – Combine it with heart-healthy oils like olive, avocado, or flaxseed oil.
• Pair it with fiber-rich foods – Whole grains, vegetables, and legumes can help counteract cholesterol effects.
• Stay active – Regular exercise supports heart health and fat metabolism.
• Choose sustainable options – Look for responsibly sourced products to reduce environmental impact.
