Kachi Ghani Tel vs Filtered Oil: What Is the Difference?
Kachi ghani and filtered oil are both marketed as traditional and natural — but they are not the same thing. Here is exactly what each term means and which is better.
What Is Kachi Ghani?
Kachi ghani (कच्ची घानी) literally means "raw press" in Hindi. It refers to the traditional method of extracting oil using a stone or wooden press (ghani) without applying external heat.
In the traditional kachi ghani process:
- Seeds (mustard, sesame, groundnut) are fed into a stone or wooden press
- The press rotates slowly, crushing the seeds under mechanical pressure
- The oil flows out naturally, without heat or chemical solvents
- The oil is filtered to remove seed particles
- No further processing — the oil goes directly into bottles
The key characteristic of kachi ghani oil is that the temperature during extraction stays below 40–50°C (the heat generated by friction alone). This preserves the oil's natural colour, aroma, vitamins, and bioactive compounds.
Kachi ghani is essentially the same as cold pressed. The terms are used interchangeably in India.
What Is Filtered Oil?
Filtered oil is a term used primarily in South India for groundnut and sesame oils. It refers to oil that has been extracted using a mechanical press (expeller) and then filtered to remove impurities.
The critical difference: filtered oil extraction often involves heat.
In the expeller pressing process:
- Seeds are fed into a mechanical screw press
- The screw rotates at high speed, generating significant friction
- Temperatures during extraction can reach 60–120°C
- The oil is then filtered to remove particles
Some filtered oils are extracted at lower temperatures and are genuinely close to cold pressed. Others are extracted at high temperatures that degrade the oil's nutritional value.
The problem: There is no standardised definition of "filtered oil" in India. The term does not guarantee cold extraction.
Side-by-Side Comparison
| Factor | Kachi Ghani | Filtered Oil |
|---|---|---|
| Extraction method | Stone/wooden press | Mechanical screw press |
| Heat during extraction | <40–50°C | 60–120°C (varies) |
| Chemical solvents | None | None |
| Nutrient retention | High | Medium to high |
| Colour | Deep, natural | Varies |
| Aroma | Strong, characteristic | Moderate |
| Shelf life | 6–12 months | 6–18 months |
| Price | Higher | Medium |
| Standardisation | No legal standard | No legal standard |
What About "Wood Pressed" and "Expeller Pressed"?
Wood pressed is essentially the same as kachi ghani — oil extracted using a wooden press (wooden ghani) at low temperatures. The terms are interchangeable.
Expeller pressed refers to mechanical extraction using a screw press. This can be done at low temperatures (close to cold pressed) or high temperatures (closer to refined). The term alone does not tell you the extraction temperature.
Which Is Better: Kachi Ghani or Filtered?
For maximum nutritional value, kachi ghani (cold pressed) is better — provided it is genuinely cold pressed.
Here is why:
1. Nutrient retention
Heat degrades vitamins (especially vitamin E), antioxidants, and bioactive compounds like allyl isothiocyanate in mustard oil. Cold pressing preserves these.
2. Fatty acid integrity
High heat during extraction can cause oxidation of polyunsaturated fatty acids, creating harmful compounds. Cold pressing avoids this.
3. Flavour
Cold pressed oils retain their natural flavour — the pungency of mustard oil, the nuttiness of sesame oil. Heat-extracted oils often have a flatter, less characteristic flavour.
4. No trans fats
Both kachi ghani and filtered oils are free of trans fats (unlike partially hydrogenated refined oils). This is a point in favour of both.
How to Verify You Are Getting Genuine Kachi Ghani Oil
The lack of legal standards for "kachi ghani" means some brands use the term loosely. Here is how to verify:
1. Colour
Genuine kachi ghani mustard oil is deep amber-gold, not pale yellow. Pale colour indicates heat processing or dilution.
2. Aroma
Real kachi ghani mustard oil has a strong, pungent smell. If it smells mild or neutral, it has been processed.
3. Consistency
Cold pressed mustard oil is slightly thicker than refined oil. It may also have a slight natural sediment.
4. Taste
Genuine kachi ghani mustard oil has a sharp, slightly bitter, pungent taste. Refined or adulterated oil tastes flat.
5. Price
Genuine kachi ghani oil costs more than refined oil because the yield is lower and the process is slower. If it is priced the same as refined oil, be sceptical.
The Bottom Line
- Kachi ghani = cold pressed = wood pressed: Oil extracted without heat, maximum nutrients retained
- Filtered oil: Mechanically extracted, may or may not involve heat — the term is not standardised
- For maximum health benefits: Choose kachi ghani (cold pressed) from a trusted source

FAQ
Kachi ghani aur filtered oil mein kya fark hai?
Kachi ghani oil bina heat ke stone ya wooden press se nikala jaata hai — temperature 40-50°C se kam rehta hai. Filtered oil mechanical press se nikala jaata hai jisme temperature 60-120°C tak ja sakta hai. Kachi ghani mein zyada nutrients hote hain.
Is filtered oil the same as cold pressed?
Not necessarily. Filtered oil is mechanically extracted and filtered, but the extraction temperature varies. Some filtered oils are close to cold pressed; others are extracted at high temperatures. "Cold pressed" or "kachi ghani" is a more specific and reliable term.
How do I know if my mustard oil is genuine kachi ghani?
Check the colour (deep amber-gold), aroma (strong and pungent), consistency (slightly thick), and taste (sharp, slightly bitter). Genuine kachi ghani mustard oil is unmistakable — if it looks and smells like refined oil, it probably is.
Why is kachi ghani oil more expensive?
Cold pressing is slower and yields less oil per kilogram of seeds compared to mechanical or solvent extraction. The lower yield and slower process make it more expensive to produce.
Can I use kachi ghani oil for deep frying?
Yes. Kachi ghani mustard oil has a smoke point of approximately 250°C, which is suitable for deep frying. It is one of the few cold pressed oils with a high enough smoke point for Indian deep frying.
Frequently Asked Questions
What is the difference between kachi ghani oil and filtered oil?
Kachi ghani oil is cold pressed at temperatures below 45 degrees Celsius using a wooden or steel press (ghani), extracting oil purely through mechanical pressure. Filtered oil typically refers to oil that has been extracted using heat or chemicals and then filtered to remove impurities. Kachi ghani retains all natural nutrients; filtered oil may have lost heat-sensitive compounds during extraction.
Is filtered mustard oil the same as cold pressed mustard oil?
Not necessarily. "Filtered" refers to the clarification process, not the extraction method. Oil can be filtered after either cold press or hot press extraction. Cold press filtered oil retains its nutrients. Hot press filtered oil has lost heat-sensitive compounds. Always look for "kachi ghani" or "cold pressed" on the label, not just "filtered."
Why is kachi ghani oil more expensive than filtered oil?
Kachi ghani extraction yields 30 to 35 percent oil from seeds compared to 40 to 45 percent for hot press or solvent extraction. The lower yield, combined with slower mechanical pressing and the cost of maintaining traditional ghani equipment, results in a higher per-litre cost. The premium reflects genuine nutritional value.
Can I use kachi ghani oil for all the same purposes as filtered oil?
Yes. Kachi ghani oil can be used for all cooking purposes that filtered oil is used for - tadka, frying, sauteing, marinades, and raw applications. Kachi ghani mustard oil has a higher smoke point (250 degrees Celsius) than most filtered oils and is nutritionally superior in every measurable way.
How do I know if oil labelled as kachi ghani is genuine?
Genuine kachi ghani oil has a strong natural aroma, a deep natural colour, and may be slightly cloudy. The producer should be able to tell you their extraction temperature (below 45 degrees Celsius) and show you their FSSAI certification. Prices significantly below market rate for kachi ghani oil are a red flag for mislabelling.
