Mustard oil (sarson ka tel) is India's most traditional cooking oil - and one of the few cooking oils that naturally contains omega-3 fatty acids (alpha-linolenic acid/ALA at 6-12% of total fat). With the highest smoke point of any cold-pressed oil (~250 degrees C), natural antimicrobial compounds (allyl isothiocyanate/AITC - the same compound that gives mustard its pungent kick), and a centuries-old place in North Indian, Bengali, and Assamese cooking, kachi ghani mustard oil is the workhorse oil that handles everything from deep frying to pickling to body massage. Organic Mandya's cold-pressed mustard oil is wood-pressed from certified organic mustard seeds below 40 degrees C, retaining the full omega-3 content, AITC antimicrobial compounds, and pungent flavour that refining strips away. Here is why this traditional oil deserves its place back in every Indian kitchen.

What Is Cold Pressed Mustard Oil (Kachi Ghani)?
Cold pressed mustard oil - known as kachi ghani mustard oil in Hindi - is extracted from organic mustard seeds (Brassica juncea/nigra) using traditional mechanical pressing without chemical solvents or high heat. The term "kachi ghani" literally means "raw pressing" - the seeds are crushed in a wooden or steel ghani (oil press) at temperatures below 40 degrees C, preserving all heat-sensitive nutrients and the characteristic pungent aroma.
Mustard oil has been the primary cooking oil of North India (Punjab, Haryana, UP, Bihar), Bengal, and Assam for centuries. It is the oil in which achar (pickle) is preserved, the oil in which fish is fried in Bengali cuisine, the oil that gives Punjabi tadka its distinctive sharpness, and the oil used in traditional body massage for babies and adults during winter.
What makes mustard oil nutritionally unique is its omega-3 content (6-12% ALA) - rare among cooking oils. Most common cooking oils (sunflower, groundnut, coconut) contain negligible omega-3. Mustard oil also contains AITC (allyl isothiocyanate) - a natural antimicrobial compound that gives mustard its pungent bite and acts as a natural preservative, which is why mustard oil pickles last for years without refrigeration.
Organic Mandya's mustard oil is certified organic, wood-pressed, and lab-tested per batch.
How Is Organic Cold Pressed Mustard Oil Made? (The Organic Story)
Organic mustard farming. Seeds are grown without synthetic pesticides or chemical fertilisers. Mustard is a naturally hardy crop that enriches soil through nitrogen fixation (it is a cruciferous plant).
Wood pressing (kachi ghani). Seeds are crushed in a traditional ghani at slow speed, below 40 degrees C. The oil seeps out under mechanical pressure. No hexane, no heat, no chemical solvents. The pungent AITC compounds are preserved because they are heat-sensitive and would degrade in refined processing.
No refining. The oil is simply filtered and bottled. No degumming, no bleaching, no deodorising. The strong pungent aroma and golden-brown colour are proof of genuine kachi ghani processing.
Every batch is lab-tested for pesticide residues, erucic acid content (FSSAI limit compliance), and trans fats. Reports at trust.organicmandya.com.

What Are the Health Benefits of Cold Pressed Mustard Oil?
1. One of the few cooking oils with omega-3 (6-12% ALA). Most cooking oils are omega-6 dominant. Mustard oil provides meaningful omega-3 (ALA), which the body partially converts to EPA and DHA - anti-inflammatory fats that support heart, brain, and joint health. For vegetarians who do not eat fish, mustard oil is one of the best dietary omega-3 sources alongside walnuts and flaxseed.
2. Highest smoke point of any cold pressed oil (~250 degrees C). This makes kachi ghani mustard oil the ONLY cold pressed oil suitable for deep frying, heavy-duty cooking, and high-heat preparations. Sunflower, groundnut, and coconut cold pressed oils all smoke at 160-180 degrees C. Mustard oil handles it all.
3. Natural antimicrobial AITC. Allyl isothiocyanate (the compound that makes your eyes water when you heat mustard oil) is a powerful natural antimicrobial. It inhibits bacterial and fungal growth, which is why mustard oil pickles last years without refrigeration. Applied externally, it has traditional use for skin infections and joint pain massage.
4. Heart health through balanced fatty acid profile. The combination of MUFA (oleic acid ~12%), PUFA (linoleic acid ~18% + ALA ~10%), and low saturated fat (~8%) creates a heart-healthy fatty acid profile. The famous "Seven Countries Study" noted lower cardiovascular disease in populations using mustard oil as primary cooking fat.
5. Zero trans fats. Cold pressing at low temperature generates no trans fats. Refined oils heated to 200+ degrees C during deodorisation can develop 0.5-2% trans fats.
6. Natural warming oil for winter massage. Traditional Indian practice: mustard oil body massage during winter improves blood circulation, warms the body, and the AITC provides mild counterirritant pain relief for sore muscles and joints. Used for baby massage across North India for centuries.

Important tip: When heating mustard oil for cooking, heat it until it just starts to smoke (the "smoking point" ritual), then reduce heat. This is a traditional North Indian practice that breaks down the pungent AITC slightly, mellowing the flavour for cooking while retaining the omega-3 fatty acids (which are more heat-stable than AITC).
Quick pickle recipe - Instant lemon pickle: Cut 4 lemons into small pieces. Mix with 2 tsp salt, 1 tsp turmeric, 1 tsp chilli powder, 1 tsp mustard seeds (crushed). Pour 100ml cold pressed mustard oil over the mixture in a glass jar. The AITC in mustard oil naturally preserves the pickle. Ready to eat in 3-5 days; lasts months without refrigeration.

How Do I Know This Mustard Oil Is Really Kachi Ghani?
NPOP certification, FSSAI licence (#11219322000392), lab reports at trust.organicmandya.com. The authenticity test is simple: genuine kachi ghani mustard oil has a strong pungent aroma that makes your nose tingle, a deep golden-brown colour, and produces a sharp, eye-watering vapour when heated. If a "kachi ghani" oil is mild, pale, and odourless, it has been refined and mislabelled.
Why Cold Pressed Mustard Oil Is India's Most Underrated Cooking Oil
Mustard oil was India's dominant cooking oil for centuries before refined sunflower and soybean oil marketing took over. It provides omega-3 that no other common cooking oil offers, handles deep frying temperatures that no other cold pressed oil can match, preserves pickles naturally through antimicrobial AITC, and has a flavour depth that refined oils simply cannot replicate.
Organic Mandya's kachi ghani mustard oil brings back the original: organic seeds, wood-pressed, zero chemicals, full omega-3, full AITC, and the pungent honesty that real mustard oil should have. Rotate it with sunflower and coconut oil across meals, and you cover the full spectrum of fatty acids your body needs - naturally.

FAQs
Q1. What are the benefits of kachi ghani mustard oil?
Omega-3 fatty acids (6-12% ALA - rare in cooking oils), highest smoke point of any cold pressed oil (~250 degrees C), natural antimicrobial AITC for pickle preservation and traditional massage, zero trans fats, and heart-healthy fatty acid profile.
Q2. Can I deep fry with cold pressed mustard oil?
Yes - it is the ONLY cold pressed oil with a smoke point (~250 degrees C) high enough for deep frying. Sunflower, groundnut, and coconut cold pressed oils all smoke at 160-180 degrees C.
Q3. Is mustard oil safe to eat?
Yes - mustard oil has been consumed across India for centuries and is FSSAI-approved for edible use. The erucic acid content is within FSSAI regulatory limits. For optimal safety, rotate mustard oil with 2-3 other oils rather than using it exclusively.
Q4. Why does mustard oil make my eyes water?
The pungent compound AITC (allyl isothiocyanate) is released when mustard oil is heated. This is the same compound in wasabi and horseradish. It is a natural antimicrobial that also acts as a mild irritant to mucous membranes. This pungency is proof of genuine kachi ghani processing - refined mustard oil loses AITC.
Q5. How is kachi ghani different from refined mustard oil?
Kachi ghani means "raw pressing" - mechanical extraction below 40 degrees C with no chemicals. Refined mustard oil uses hexane extraction, high heat, degumming, bleaching, and deodorisation. Kachi ghani retains omega-3, AITC, and pungent flavour; refined loses most of these.
