Kachi Ghani vs Refined Mustard Oil — What's the Real Difference?
Kachi ghani and refined mustard oil look similar in the bottle but are worlds apart in nutrition, flavour, and safety. Here is exactly what separates them.
What Does "Kachi Ghani" Actually Mean?
Kachi means raw or unrefined. Ghani refers to the traditional wooden or stone press used to extract oil from seeds. Together, kachi ghani describes a cold extraction process where mustard seeds are pressed slowly at low temperatures — typically below 45°C — without any chemical solvents or external heat.
The result is oil that retains everything the mustard seed naturally contains: its pungent aroma, deep amber colour, Omega-3 fatty acids, Vitamin E, and allyl isothiocyanate (the compound responsible for mustard oil's characteristic heat and many of its health benefits).
At Dune Aura, our kachi ghani sarson ka tel is pressed in traditional wooden Ghanis at our facility in Sector 9A, Gurgaon — the same method used for generations across North India.
How Refined Mustard Oil is Made
Refined mustard oil goes through a very different journey. Here is the typical industrial process:
- Solvent extraction — Seeds are soaked in chemical solvents (usually hexane) to extract maximum oil yield
- Degumming — Phospholipids are removed using hot water or acid
- Neutralisation — Free fatty acids are removed using caustic soda (sodium hydroxide)
- Bleaching — Colour pigments are removed using activated clay or charcoal
- Deodorisation — The oil is steam-treated at temperatures between 200°C and 270°C to remove odour
By the end of this process, the oil is pale, odourless, and shelf-stable — but most of its nutritional value has been destroyed or removed.
Side-by-Side Comparison
| Property | Kachi Ghani Cold Press | Refined Mustard Oil |
|---|---|---|
| Extraction temperature | Below 45°C | 200–270°C (deodorisation) |
| Chemical solvents | None | Hexane (industrial solvent) |
| Colour | Deep amber | Pale yellow to colourless |
| Aroma | Strong, pungent, characteristic | Mild to odourless |
| Omega-3 (ALA) | Preserved | Largely destroyed |
| Vitamin E | Preserved | Largely destroyed |
| Allyl isothiocyanate | Present | Removed |
| Shelf life | 6–12 months | 18–24 months (due to additives) |
| Smoke point | ~160°C | ~240°C (due to refining) |
The Nutrition Gap
The most significant difference between kachi ghani and refined mustard oil is nutritional density.
Omega-3 fatty acids (ALA): Cold press mustard oil contains approximately 6–11% alpha-linolenic acid (ALA), one of the few plant-based Omega-3 sources available in Indian cooking. The high-heat deodorisation process in refining converts much of this ALA into trans fats — the same fats associated with cardiovascular risk.
Vitamin E: Mustard seeds are naturally rich in tocopherols (Vitamin E), which act as antioxidants in the body. These are heat-sensitive and largely destroyed during refining.
Glucosinolates and allyl isothiocyanate: These compounds give mustard oil its characteristic pungency and are associated with antimicrobial and anti-inflammatory properties. Refining removes them entirely.
What About the Smoke Point?
A common argument for refined oil is its higher smoke point (~240°C vs ~160°C for cold press). This is true — but it is worth understanding why.
Refined oil has a higher smoke point precisely because everything that burns at lower temperatures — the volatile compounds, the antioxidants, the flavour molecules — has already been removed. You are essentially cooking with a chemically stripped fat.
For most Indian cooking — tadka, sautéing, shallow frying — temperatures rarely exceed 180°C. Cold press mustard oil is perfectly suited for these applications. For deep frying at very high temperatures, refined oil may be more practical, but the nutritional trade-off is significant.
The Flavour Difference
If you have grown up eating food cooked in kachi ghani sarson ka tel, you know the difference immediately. The pungency, the warmth, the depth it adds to a dal tadka or a sarson da saag — these come from the volatile compounds that refining destroys.
Refined mustard oil is essentially a neutral cooking fat with a mustard label. Kachi ghani is an ingredient in its own right.
Which Should You Choose?
For everyday cooking — dal, sabzi, tadka, marinades, pickles — kachi ghani cold press mustard oil is the clear choice. You get full nutrition, authentic flavour, and none of the chemical processing.
For very high-heat deep frying, refined oil may be more practical. But even then, consider whether deep frying is a daily activity that warrants keeping refined oil as your primary cooking fat.

FAQ
What does kachi ghani mean? Kachi ghani means oil extracted by the raw press method — without heat, without solvents, without any processing beyond slow mechanical pressure. "Kachi" means raw or unprocessed; "ghani" refers to the traditional wooden or stone press used to extract oil from seeds. Kachi ghani mustard oil is pressed at below 45°C, preserving all the natural nutrients, pungency, and flavour of the mustard seed.
What is the difference between kachi ghani and refined mustard oil? Kachi ghani is cold pressed at below 45°C with no chemical solvents — the oil retains its deep amber colour, strong pungency, omega-3 fatty acids, vitamin E, and allyl isothiocyanate. Refined mustard oil is extracted with hexane solvent at 200–270°C, then bleached and deodorised — producing a pale, odourless oil that has lost most of its nutritional value. The smoke point of refined oil is higher (~240°C vs ~160°C for kachi ghani), but this is because all the volatile beneficial compounds have been removed.
Is kachi ghani mustard oil better for cooking? For everyday Indian cooking — dal tadka, sabzi, marinades, pickles — kachi ghani cold press mustard oil is the clear choice. It delivers full nutrition, authentic flavour, and none of the chemical processing. For very high-heat deep frying above 180°C, refined oil may be more practical due to its higher smoke point, but most Indian cooking does not reach those temperatures.
Why does refined mustard oil have no smell? Refined mustard oil has no smell because the deodorisation process — steam treatment at 200–270°C — removes the volatile compounds responsible for mustard oil's characteristic pungency, primarily allyl isothiocyanate. These same compounds are responsible for many of mustard oil's health benefits. If your mustard oil has no smell, it has been refined and the beneficial compounds are gone.
How can I tell if mustard oil is genuinely kachi ghani? Three clear indicators: deep amber-gold colour (not pale yellow), a strong characteristic pungent smell, and an explicit "cold pressed below 45°C" statement on the label. Genuine kachi ghani cannot be pale and odourless — if it is, it has been refined regardless of what the label says.
