Walk into any Indian grocery store and you will see bottles labelled "kachi ghani," "cold-pressed," "wood-pressed," and "lakdi ghani." Some brands use these terms interchangeably. Others treat them as separate categories with different price tags. Buyers searching for genuine kachi ghani oil or lakdi ghani oil often end up confused about what they are actually paying for.
These terms come from different languages and different points of focus in the extraction process. "Kachi ghani" describes what happens to the seed. "Lakdi ghani" describes what the press is made of. "Cold-pressed" is the English umbrella. And "refined" is the industrial process that strips all three of their meaning. This article breaks down each term and covers what Indian food regulations actually require for each label.
What Does Kachi Ghani Oil Mean?
"Kachi ghani" translates to "raw press" in Hindi. "Kachi" means raw or unprocessed. "Ghani" refers to the traditional oil press, a mortar-and-pestle apparatus where a heavy vertical pestle rotates inside a cylindrical pit, crushing oilseeds under lateral pressure. The term tells you that the seeds were pressed without pre-heating, roasting, or any thermal treatment before extraction.
Under FSSAI (Food Safety and Standards Authority of India) regulations, kachi ghani oil must meet specific criteria. For kachi ghani mustard oil, the allyl isothiocyanate (AITC) content must be at least 0.20% by weight, confirming genuine mustard oil that has not been refined or diluted (FSSAI, Food Products Standards and Food Additives Regulations, Chapter 2.2). AITC is the pungent compound that gives mustard oil its characteristic nose-clearing sharpness, and it degrades during high-heat processing.
FSSAI Quality Parameters for Kachi Ghani Mustard Oil
| Parameter | FSSAI / Agmark Limit | What It Indicates |
|---|---|---|
| Allyl isothiocyanate (AITC) | Min 0.20% by weight | Confirms genuine, unrefined mustard oil |
| Acid value | Max 6.0 (FSSAI); max 1.5 (Agmark Grade I) | Freshness; lower is better |
| Iodine value | 96 to 112 | Confirms fatty acid profile matches mustard |
| Saponification value | 168 to 177 | Identity marker; detects mixing with other oils |
| Peroxide value | Max 15 meq O2/kg | Oxidation level; higher means rancidity |
| Hexane residue | Absent (detection limit 0.1 ppm) | Confirms no solvent extraction |
| Moisture and impurities | Max 0.25% | Excess moisture causes spoilage |

Under FSSAI rules, "kachi ghani" means mechanically extracted, with no external heat applied before pressing, no chemical solvents, and AITC content intact. A brand that prints "kachi ghani" on a bottle of solvent-extracted oil is violating FSSAI labelling norms. For buyers, the regulated kachi ghani oil label is a stronger guarantee than vague terms like "pure" or "natural."
What Does Lakdi Ghani Oil Mean?
"Lakdi ghani" translates to "wooden press" in Hindi. "Lakdi" means wood. Where "kachi ghani" tells you about the process (raw pressing), "lakdi ghani" tells you about the equipment: a press built from wood rather than metal.
The traditional Indian ghani was almost always made of wood. The FAO documents that ghani mortars in western India were carved from tamarind, neem, baheda, or sal wood, while southern variants used granite stone bases with wooden pestles (FAO, 1993).
Why Wood Matters in Oil Extraction
The material of the press affects the oil in three ways:
-
Heat absorption: Wood absorbs and disperses friction heat rather than transferring it to the seed paste. A wooden ghani keeps extraction temperatures below 40 to 45 degrees Celsius. Steel expellers generate significantly higher friction, with commercial units reaching 100 to 150 degrees Celsius during operation.
-
Speed: Traditional wooden ghanis rotate at fewer than 15 revolutions per minute. Modern steel expellers run at several hundred RPM. Slower pressing means less friction heat and more time for oil to separate from the seed without thermal degradation.
-
Contact surface: Wood does not react with the oil's fatty acids the way some metals can. This preserves the oil's natural flavour and colour.
The trade-off is yield. A wooden ghani extracts roughly 60% of the available oil from the seed, leaving about 15% residual fat in the oilcake. A modern steel expeller recovers close to 90%, and solvent extraction pushes that even higher (FAO, 1993). This yield gap is the primary reason lakdi ghani oil costs more per litre.
Lakdi Ghani Oil: No Separate FSSAI Category
FSSAI does not have a separate labelling category for "lakdi ghani" or "wood-pressed" oil. Lakdi ghani oil falls under the same "cold-pressed" or "kachi ghani" category, provided extraction happens below 50 degrees Celsius without solvents.
| Term | What It Describes | FSSAI Recognition |
|---|---|---|
| Kachi ghani | Raw pressing, no pre-heating | Yes, regulated for mustard oil |
| Lakdi ghani / Wood-pressed | Wooden press | Falls under cold-pressed |
| Cold-pressed | Mechanical extraction below 50 degrees Celsius | Yes, regulated labelling term |
| Refined | Solvent extraction + degumming + bleaching + deodorisation | Yes, separate category |
A brand can label its oil "wood-pressed" or "lakdi ghani" as a descriptor, but the regulatory compliance is the same as any cold-pressed oil.
The Ghani: A 3,000-Year-Old Technology
The ghani is one of the oldest documented oil-extraction technologies in the world. Mortar-and-pestle crushing systems for oilseeds existed in India as early as 1500 BCE, and by the early twentieth century, approximately 500,000 ghanis were operating across the country, processing about 97% of India's oilseeds (FAO, 1993).
The process is slow by design. A heavy wooden pestle rotates inside a carved pit, crushing seeds under lateral pressure. Small amounts of water are added in stages to separate phospholipids and gums. The oil seeps out through a channel at the base, settles naturally, and goes into the bottle without filtering, bleaching, or deodorising. A traditional ghani handles about 50 kg of seed per day; a motorised version manages about 100 kg.
By the 1980s, operating ghanis had dropped to an estimated 100,000 to 150,000. Today, ghanis process only about 4% of India's oilseeds. Steel expellers and solvent-extraction plants, with their higher yields, pushed the ghani to the margins.
The revival came from consumer demand. Health-conscious Indian buyers started asking what refining was removing from their oil. When the answer turned out to be phospholipids, AITC, lignans, tocopherols, and natural colour, the wooden ghani's slow, low-heat process found a new market. Indic Wisdom's manufacturing process uses wood-pressing that keeps every step mechanical and chemical-free.
Kachi Ghani Oil vs Cold-Pressed Oil: Are They the Same?
Both terms describe mechanical oil extraction below 50 degrees Celsius, without chemical solvents. The practical difference: "kachi ghani" is most commonly used for mustard oil and carries a specific FSSAI AITC requirement. "Cold-pressed" is the broader category covering all oil types.
| Feature | Kachi Ghani | Cold-Pressed (General) |
|---|---|---|
| Language | Hindi | English (international) |
| Seeds pre-heated? | No (the "kachi" / raw part) | No external heat applied |
| Extraction temperature | Below 50 degrees Celsius | Below 50 degrees Celsius |
| FSSAI recognition | Yes, specific label for mustard oil | Yes, general category |
| Equipment specified? | No (wooden or metal ghani) | No (any mechanical press) |
A bottle labelled “cold-pressed sesame oil" and a bottle labelled "kachi ghani mustard oil" are both extracted the same way. The label reflects the oil type, not a different process.
What About Kachi Ghani Mustard Oil Price?
Kachi ghani mustard oil costs more than refined mustard oil. The price gap comes from production realities: a ghani extracts 28 to 35% of the oil from seeds (versus 45 to 50% with solvent extraction), processes only 50 to 100 kg of seed per day, and uses no hexane to recover residual oil from the oilcake.
Refined mustard oil typically sells at Rs 120 to 160 per litre in Indian retail. Kachi ghani mustard oil from established brands ranges from Rs 220 to 400 per litre, depending on seed quality and whether the extraction is wood-pressed or steel-pressed. The price difference reflects extraction efficiency, not premium branding.
How to Tell Kachi Ghani Oil from Refined Oil
Your senses handle the first filter when comparing kachi ghani oil to refined oil:
Sensory Comparison
| Characteristic | Kachi Ghani Oil | Refined Oil |
|---|---|---|
| Colour (mustard oil) | Deep amber to golden brown | Pale yellow, almost clear |
| Aroma (mustard oil) | Sharp, pungent, nose-clearing | Flat, neutral, minimal smell |
| Taste | Bold, slightly bitter, seed-forward | Bland, oily, no distinctive flavour |
| Foam when heated | Yes, light white froth for 1 to 2 minutes | None (phospholipids removed; anti-foaming agents may be added) |
| Sediment | Fine natural sediment may settle at the bottom | Completely clear |
The foam test is particularly useful. Cold-pressed kachi ghani oil retains phospholipids that cause harmless white foaming when heated. Refined oil does not foam because these compounds are stripped during degumming. If your "kachi ghani" mustard oil heats without any foam, it may not be genuinely cold-pressed. Learn more about why cold-pressed oils foam.
Beyond sensory tests, check the label for the FSSAI license number (verify at foscos.fssai.gov.in), ask for a lab report showing zero hexane residue and AITC at or above 0.20%, and look for a traceable manufacturing address. Browse Indic Wisdom's lab reports to see what a NABL-certified test result looks like for wood-pressed kachi ghani oil.
Choosing Between Kachi Ghani, Lakdi Ghani, and Cold-Pressed
-
Want mustard oil? Look for "kachi ghani" on the label. Confirm FSSAI certification and check that AITC content is listed or available on request.
-
Want sesame, groundnut, or coconut oil? Look for "cold-pressed" or "wood-pressed." The kachi ghani label is not commonly used for these oils.
-
Want the lowest extraction temperature? Lakdi ghani (wood-pressed) runs cooler than steel expeller cold-pressed, typically below 40 to 45 degrees Celsius versus up to 50 degrees in a steel press.
-
Is budget the priority? Cold-pressed oil from a steel expeller costs less than lakdi ghani oil from a wooden press, while still being far superior to refined oil in nutrient retention.
For a kitchen that uses multiple oils, Indic Wisdom's cold-pressed cooking oil range covers mustard, sesame, groundnut, coconut, and sunflower, all wood-pressed.
Conclusion
"Kachi ghani" means raw-pressed: no pre-heating of seeds, mechanical extraction, no solvents. "Lakdi ghani" means wood-pressed: the same process, but on a wooden press that runs cooler and slower than a steel expeller. "Cold-pressed" is the English-language umbrella covering both. And "refined" is a different category entirely, involving hexane solvents, degumming, bleaching, and deodorisation that strip the very compounds that make kachi ghani oil worth buying.
FSSAI regulates "kachi ghani" and "cold-pressed" as labelling terms with specific compliance requirements. "Lakdi ghani" and "wood-pressed" fall under the same cold-pressed category. The terms are not interchangeable in meaning, but they describe overlapping parts of the same extraction philosophy: get the oil out of the seed with pressure, not chemistry.
Next time you pick up a bottle, read the label with these definitions in mind. The price of kachi ghani oil reflects lower yields and slower processing, not premium branding.

Frequently Asked Questions
What does kachi ghani oil mean in English?
Kachi ghani translates to "raw press" in English. It refers to oil extracted by crushing seeds in a traditional press without pre-heating or roasting. The process uses no chemical solvents and keeps extraction temperatures below 50 degrees Celsius. Under FSSAI regulations, kachi ghani mustard oil must contain at least 0.20% AITC by weight.
Is lakdi ghani oil the same as kachi ghani oil?
Not exactly. Lakdi ghani means "wooden press" and describes the equipment. Kachi ghani means "raw press" and describes the process. Lakdi ghani oil is always kachi ghani oil (wood-pressing is inherently raw pressing), but kachi ghani oil is not always lakdi ghani oil, because some kachi ghani extraction happens on metal presses. Both fall under the FSSAI cold-pressed category.
Why is kachi ghani mustard oil more expensive than refined?
Kachi ghani extraction yields 28 to 35% oil from seeds, compared to 45 to 50% with solvent extraction. The process is slower (50 to 100 kg per day versus tonnes in an industrial plant) and uses no hexane to recover residual oil from the oilcake. More raw material, more time, and no chemical shortcuts result in a higher cost per litre.
How can I check if my kachi ghani oil is genuine?
Start with three checks: verify the FSSAI license number on foscos.fssai.gov.in, ask the brand for a NABL-certified lab report showing zero hexane residue and AITC at or above 0.20% (for mustard oil), and use your senses. Genuine kachi ghani mustard oil is deep amber, sharp-smelling, and foams lightly when heated. If the oil looks pale, smells neutral, or heats without foaming, it may be refined.
Does FSSAI recognise "wood-pressed" as a separate category?
No. FSSAI does not have a separate labelling category for "wood-pressed" or "lakdi ghani" oil. These terms are treated as descriptors that fall under the regulated "cold-pressed" or "kachi ghani" category. The oil must meet the same standards: mechanical extraction below 50 degrees Celsius, no chemical solvents, and the relevant quality parameters for that oil type.
