Why Chemical-Free Cooking Oil Is Getting Attention

The growing interest in chemical-free cooking oil comes mainly from increased awareness about food processing.

Many refined oils can involve:

• High temperatures
• Multiple refining stages
• Chemical solvents in some extraction methods
• Processes designed to increase oil yield and create a more neutral-looking and neutral-tasting oil

These processes can make oil suitable for large-scale production, but they can also change the natural character of the oil.

Cold-pressed oils work differently.

Instead of relying on chemical solvent extraction, the seeds are mechanically pressed to release their natural oil. Traditional methods such as the Marachekku (Kachi Ghani) method use a slower extraction process.

This is the approach that inspires TREFO’s cold-pressed oils.

Because the oil undergoes less processing, it can retain more of the natural aroma, taste and character associated with the seed it comes from.

Sesame oil has the characteristic aroma of sesame. Groundnut oil has its naturally rich, nutty character. Sunflower oil is lighter and suitable for everyday cooking, while coconut oil has the familiar aroma and character associated with coconut.

For many consumers, that difference matters.

Chemical-Free Cooking Oil and the Shift Back to Simpler Food

The interest in chemical-free cooking oil is part of a bigger change happening in kitchens today.

People are increasingly looking for:

• Less processed foods
• Simpler ingredients
• Traditional food preparation methods
• Greater transparency about how products are made

Cooking oil naturally became part of this conversation because it is something most families use almost every day.

Many consumers now look for oils that are:

• Hexane-free
• Unrefined
• Cold-pressed
• Made from quality seeds
• Produced with minimal processing

The goal isn’t to make food complicated. In fact, it is quite the opposite.

Sometimes, people simply want to know what they are putting into their food and how it was made.

That is where traditional extraction methods have a place in modern kitchens.

The Marachekku (Kachi Ghani) method has a long history in traditional Indian oil-making. It uses mechanical extraction rather than chemical solvent extraction. At TREFO, we combine this traditional approach with modern production and quality practices to produce cold-pressed cooking oils for homes in Zambia.

Does Chemical-Free Cooking Oil Mean Completely Natural?

This is where some confusion can happen.

When people hear the words “chemical-free cooking oil,” they may imagine oil going directly from a seed into a bottle without any processing whatsoever.

That isn’t quite how commercial food production works.

Even cold-pressed oils need to go through important steps such as:

• Cleaning the seeds
• Mechanical pressing
• Filtration
• Quality checks
• Bottling

The important difference is how the oil is extracted and how much processing it undergoes.

At TREFO, our cold-pressed oils are produced through mechanical extraction without chemical solvent extraction. We focus on preserving the natural character of the oil rather than heavily processing it to change its appearance, aroma or taste.

This is why terms such as Cold-pressed, Unrefined and Hexane-free are useful for consumers. They give you a better understanding of how the oil was produced.

And you can often notice the difference while cooking.

The aroma can be more characteristic of the original seed. The taste can feel more natural. The oil has its own identity rather than being completely stripped of its original character.

That is one of the reasons people are choosing cold-pressed oils today.

Choosing the Right Cold-Pressed Oil for Your Kitchen

There isn’t necessarily one oil that has to be used for everything. Different oils have different flavours and characteristics, so you can choose according to the type of food you are preparing.

Choosing between oils doesn’t have to be complicated. You can simply choose the oil whose taste and characteristics suit your cooking.

How to Store Cold-Pressed Cooking Oil

Cold-pressed oils are minimally processed, so proper storage is important.

A few simple habits can help:

• Keep the bottle tightly closed when not in use.
• Store it away from direct sunlight.
• Keep it in a cool, dry place.
• Avoid leaving the bottle open for long periods.
• Use clean, dry utensils when handling the oil.

Good storage helps maintain the quality and natural characteristics of the oil.

So, Does Chemical-Free Cooking Oil Really Exist?

The phrase “chemical-free cooking oil” can be confusing because, scientifically speaking, everything around us is made of chemicals, including natural foods.

When consumers use the term “chemical-free oil,” they generally mean an oil that has not been extracted using chemical solvents and has not gone through unnecessary chemical-intensive processing.

This is where the difference between refined and cold-pressed oils becomes important.

TREFO cold-pressed oils are mechanically extracted from quality seeds, following a traditional cold-pressed approach. The oils are unrefined and hexane-free, allowing the natural character of the seed to remain part of the finished oil.

So rather than simply looking for the words “chemical-free” on a bottle, look at the bigger picture:

What seeds were used?
How was the oil extracted?
Was it refined?
Was chemical solvent extraction used?
How much processing did it undergo?

These questions can tell you much more about the oil you are buying.

The TREFO Difference

At TREFO Zambia, we believe that good cooking oil starts with good seeds and a thoughtful extraction process.

Our range includes:

• TREFO Cold-Pressed Sunflower Oil
• TREFO Cold-Pressed Groundnut Oil
• TREFO Cold-Pressed Sesame Oil
• TREFO Cold-Pressed Coconut Oil

Our approach is simple: start with quality seeds and use mechanical cold-press extraction rather than chemical solvent extraction.

The idea isn’t to make exaggerated promises about what an oil can do. It is about giving consumers a more transparent choice and helping them understand what goes into the oil they use every day.

Because cooking oil is more than just another ingredient in the kitchen.

It is something we use regularly, often without thinking about where it came from.

Maybe it is time to think about it.

From seed → extraction → your kitchen.

That is the journey behind TREFO cold-pressed oils.
