Hexane-free oil is oil that was never touched by hexane, a chemical solvent used to strip extra oil out of seeds during large-scale refining. It's made only by pressing - nothing else goes near the seed.
Every day, oil goes into our food without a second thought. A spoon for the dosa. A splash for the tadka. A cup for Sunday's fry. We think carefully about which oil to buy - groundnut, coconut, sesame, mustard. We rarely ask the one question that matters just as much:
How did this oil get out of the seed and into the bottle?
Why Is Hexane Used in Oil at All?
Press a groundnut, and you'll get oil - but not all of it. Some always stays trapped in the leftover pulp. For a home kitchen, that's nothing. For a factory running through tons of seed a day, it's oil worth chasing.
So instead of pressing twice, factories rinse the pulp in hexane, which pulls the last of the oil out. The hexane is then evaporated away, and the oil moves on to refining.
It's fast. It's cheap. But it's a world away from a seed simply being pressed, with nothing else touching it.
Does Refined Oil Contain Hexane?
Not always - but sometimes, yes. Most of the hexane is removed by the time refined oil reaches your kitchen. Not all of it.
In India, FSSAI allows refined, hexane-extracted oil to carry up to 5 mg of hexane per kg. Small, and regulated for safety - but not zero. Oil that's simply pressed is required to have zero hexane, because hexane never touched it to begin with.
Cold Pressed Oil vs Refined Oil
| Cold Pressed Oil | Refined Oil | |
|---|---|---|
| Extraction | Pressed only | Pressed, then hexane-extracted |
| Solvent used | None | Hexane |
| Hexane in final oil | Zero | Up to 5 mg/kg (FSSAI limit) |
| Processing after pressing | None | Bleached, deodorized, chemically treated |
| Flavour & aroma | Strong, natural | Milder, often lost in processing |
Same seed. Two completely different journeys.
This simpler path is exactly how oil was made at the local chekku for generations - you brought your seeds, watched them pressed, and carried the oil home yourself. You knew exactly what went in.
We've traded that for ordering groceries on our phones. But the reason we trusted that oil hasn't changed - we still want to know what happened to our food. We've just lost the ability to see it.
Why Families Are Going Back to Cold Pressed Oil
The reasons vary - some want no solvent near their food, some prefer the traditional process, many simply say it tastes better and more natural. But underneath it all is one shared feeling: oil goes into nearly every meal a family eats. That deserves more than a passing thought.
What to Check Beyond the Label
A genuinely hexane-free oil is genuinely cold pressed - that part is simple. Before trusting a label, still ask:
- Does the brand explain how it's pressed, not just call it "pure"?
- Do they say where it's made, and from what seeds?
- Is it stored in food-safe steel, or plastic that can leach into it?
If a brand can't answer these, the label alone proves nothing.
How Chekko Makes Its Oil
We press every oil - groundnut, sesame, coconut, mustard - using a traditional wooden cold-press, with no hexane at any stage. We also use non-GMO seeds, sulphur-free copra for our coconut oil, and our own factory, so nothing is out of our hands. The oil is stored in food-grade steel, never plastic, and packed in food-grade tins.

Because this oil becomes someone's breakfast, lunch, and dinner - that's not a place for shortcuts.
Turn the Bottle Around Next Time
We were taught to pick oil by the seed. Now there's one more thing worth checking - how it was made. You don't need to be a scientist. Just ask:
How did this seed become the oil I'm taking home?
Once you ask that, cold pressed, refined, and hexane-free all start making sense.
Stay uncompromised with Chekko.
FAQs
Is cold pressed oil hexane free?
Yes. It's only ever pressed, never treated with a solvent - so it has zero hexane.
Does refined oil contain hexane?
It can, if it was solvent-extracted. FSSAI caps the residue at 5 mg/kg - small and regulated, not unlimited.
Is hexane-free oil healthier than refined oil?
Not automatically - it describes the process, not the nutrition. People choose it for fewer chemicals and a more natural taste.
Why is cold pressed oil more expensive?
It recovers less oil per seed and is usually made in smaller batches with more care. You're paying for the process.
Which cold pressed oil suits Indian cooking best?
Depends on the dish - groundnut & sunflower for everyday cooking and frying, sesame for gravies and pickles, coconut wherever its flavour belongs, and mustard for north indian dishes.
