Ghee vs Mustard Oil: Which Is Better for Cooking?
Ghraam Team
Part of our Complete A2 Ghee Guide. See the full picture of A2 ghee sourcing, purity, and buying advice.
Quick answer: Both ghee and mustard oil have high smoke points (around 250°C) suited to Indian cooking. The real difference is regulatory. Mustard oil contains erucic acid, which is why it's banned for culinary sale in the EU and US, while FSSAI permits it in India and human data hasn't shown the harm the original animal studies raised concern about. Neither oil is "wrong" to use, but purity and testing matter for both, especially given mustard oil's documented history of dangerous adulteration.
Key takeaway: This comparison isn't really about which fat cooks better; both handle Indian high heat well. It's about an honest look at a genuine, unresolved regulatory debate around mustard oil, and why buying tested, reputable products matters regardless of which oil you choose.
Who this guide is for: Anyone deciding between ghee and mustard oil for everyday Indian cooking, or who's seen conflicting claims about mustard oil's safety and wants the actual regulatory picture rather than a one-sided take. GHRAAM is a Delhi-based D2C brand making traditional A2 cow and buffalo ghee. This guide covers both oils honestly, not just the one we sell.
Smoke Point: Genuinely Similar
| Ghee | Mustard Oil | |
|---|---|---|
| Smoke point | ~250°C (482°F) | ~250°C (480°F) |
| Suited to | Tadka, frying, roasting, deep frying | Tadka, sautéing, shallow frying |
| Flavour | Rich, nutty | Pungent, sharp (mellows when heated) |
| Regulatory status in India | No erucic acid concern (dairy fat, not a seed oil) | FSSAI-permitted, no current upper limit on erucic acid |

The Erucic Acid Debate, Explained Honestly
Mustard oil naturally contains erucic acid, a fatty acid that raised health concerns after rat studies decades ago showed cardiac fat deposits (myocardial lipidosis) at high doses. This led the EU and US to restrict or ban mustard oil for culinary use, while food-grade "low erucic acid" varieties like canola were developed as an alternative. A 2025 review published in ScienceDirect notes that the European Food Safety Authority has revised its guidance on tolerable erucic acid intake over time, and that erucic acid levels in Indian mustard oil samples commonly exceed international limits.
At the same time, it's worth noting the other side. Rats process very-long-chain fatty acids differently from primates, and human epidemiological data from mustard-oil-consuming Indian populations spanning decades hasn't shown the elevated cardiac disease rates the original animal studies raised concern about. FSSAI permits mustard oil for food use in India with no current erucic acid upper limit, treating it as a traditional Indian cooking oil.
So this is a real, ongoing scientific and regulatory disagreement between jurisdictions, not a settled question either way. Moderation and oil rotation, rather than relying on any single oil exclusively, is commonly advised by nutrition professionals as a sensible middle ground for mustard oil, as for most concentrated fats.
Purity Matters More Than the Oil Itself
This is the part worth taking seriously regardless of which oil you use. In 1998, adulterated mustard oil, mixed with a toxic industrial oil, caused a poisoning outbreak in Delhi that killed 60 people and sickened over 3,000. This wasn't a problem with mustard oil itself. It was a problem with adulteration and inadequate testing, which is exactly why FSSAI's current standards for mustard oil specifically require a negative test for argemone oil contamination, and why FSSAI banned blending mustard oil with any other edible oil from October 2020 onward.
The lesson applies just as much to ghee. Purity testing isn't a nice-to-have; it's the actual difference between a safe product and a genuinely dangerous one, for any cooking fat. It's precisely why GHRAAM tests every batch through an NABL-accredited lab rather than relying on packaging claims alone.
GHRAAM tests every batch through an NABL-accredited lab, so purity isn't something you have to take on faith. You can check the actual batch reports on our Lab Reports page before you buy.
So, Which Should You Actually Use?
- If you already use mustard oil and it's part of your family's tradition: there's no strong evidence requiring you to stop, especially with moderation and oil rotation. Buy from a reputable, tested brand though, given the documented adulteration history.
- If you're mustard-oil-averse or want to avoid the erucic acid question entirely: ghee is a genuinely equivalent high-heat option with none of that particular regulatory debate attached.
- Either way: purity testing and reputable sourcing matter more than which oil you pick.
Frequently Asked Questions
Is mustard oil banned in India?
No. FSSAI permits mustard oil for food use in India, with no current upper limit on erucic acid content. The ban exists only in certain markets like the EU and US.
Why is mustard oil banned in the US and EU but not India?
The ban is based on rat studies from decades ago showing cardiac effects from high erucic acid doses. Human epidemiological data from Indian populations hasn't shown the same elevated risk, and regulatory approaches differ by jurisdiction. This remains a genuinely unresolved scientific debate, not a settled question.
Does ghee have a similar smoke point to mustard oil?
Yes, both sit at roughly 250°C, making them similarly suited to Indian high-heat cooking methods like tadka and frying.
What happened in the 1998 Delhi mustard oil poisoning?
Adulteration with argemone oil, a toxic industrial oil mixed in to cut costs, caused widespread illness and 60 deaths. It wasn't a problem with mustard oil itself, but it's why FSSAI now mandates argemone-negative testing and banned blending mustard oil with other oils.
Should I switch from mustard oil to ghee?
Not necessarily. This isn't a case where one oil is clearly better. If you're comfortable with mustard oil and buy from a tested, reputable brand, there's no strong evidence requiring a switch. Ghee is simply an equivalent high-heat alternative without the erucic acid debate.
