The 6-Step Kachi Ghani Process
Every step is designed to preserve what nature put into the seed — not to maximise yield at the cost of quality.
Seed Selection & Cleaning
Premium mustard seeds are hand-sorted and cleaned to remove impurities, stones, and damaged seeds. Only Grade-A seeds enter the press. Seed quality directly determines oil quality — we never compromise here.
Variety: DSS 53 mustard seeds · Moisture: 8–10% · Zero damaged seeds
Conditioning (No Heat)
Seeds are conditioned to the correct moisture level for optimal oil yield. Unlike industrial processes, we do not pre-heat or roast seeds — roasting increases yield but destroys the natural compounds that make cold pressed oil valuable.
Temperature: Ambient · Duration: 2–4 hours · No roasting, no pre-heating
Cold Pressing Below 45°C
Seeds are fed into the wooden ghani (cold press) and pressed slowly. The press speed is calibrated so friction heat never exceeds 45°C. This preserves all Omega-3 fatty acids, Vitamin E, glucosinolates, and the authentic pungent aroma.
Max temperature: 45°C · Press speed: Slow (traditional ghani) · No solvents
Natural Settling
Freshly pressed oil is transferred to settling tanks and left undisturbed for 24–48 hours. Fine seed particles and natural sediment sink to the bottom by gravity — no centrifuges, no chemical clarifiers.
Duration: 24–48 hours · Method: Gravity settling · No chemical clarifiers
Cloth Filtration
The clear oil is filtered through multiple layers of food-grade cloth to remove any remaining fine particles. This is the same method used for centuries — no diatomaceous earth, no activated clay, no bleaching agents.
Filter: Food-grade cloth · Stages: Multiple passes · No chemical filtration
Quality Check & Bottling
Every batch is checked for colour, aroma, clarity, and purity before bottling. Oil is filled into food-safe HDPE containers and sealed. FSSAI certified at every stage from seed to bottle.
Certification: FSSAI · Containers: Food-safe HDPE · Batch traceability
Why the Process Matters
The difference between cold pressed and refined oil is entirely in the process.
Temperature is everything
Above 60°C, Omega-3 fatty acids begin to oxidise. Above 100°C, Vitamin E degrades. Above 150°C, glucosinolates are destroyed. Cold pressing stays below 45°C — the only method that preserves all three.
No hexane, no residues
Industrial refining uses hexane (a petroleum solvent) to extract the last 5–10% of oil from the seed cake. Cold pressing uses only mechanical pressure — zero chemical contact, zero residues.
Nutrients stay intact
Cold pressed mustard oil retains 6–14% ALA (Omega-3), 15–30% linoleic acid (Omega-6), natural Vitamin E, and glucosinolates — the compounds responsible for mustard's health benefits and authentic flavour.
FSSAI certified process
Every step of the Dune Aura cold pressing process is certified under FSSAI food safety standards. From seed selection to bottling, each batch is traceable and quality-checked.
Cold Pressed vs Expeller vs Refined
Three extraction methods — very different results.
Frequently Asked Questions
What is kachi ghani cold press oil?
Kachi ghani means "raw press" or "cold press" in Hindi. Oil is extracted from seeds using a slow mechanical press at below 45°C — without heat, chemicals, or solvents. The result retains full nutritional profile.
What temperature is used in cold pressing?
Cold pressing keeps oil temperature below 45°C throughout extraction. Refined oil is processed at 160–220°C, which destroys heat-sensitive nutrients like Omega-3 and Vitamin E.
Is cold pressed oil the same as expeller pressed?
No. Expeller pressing generates 80–120°C from mechanical friction. Cold pressing is slower and lower-pressure, staying below 45°C. Cold pressed retains significantly more nutrients.
How long does cold pressing take?
Cold pressing takes 4–6 hours per batch. The slow process is what preserves quality — it cannot be rushed without generating heat that destroys nutrients.
